| Conteúdo: | Abstract: The evolutionary history of crop pathogens is shaped by a complex interaction of natural and anthropogenic factors. The fungus Colletotrichum graminicola causes maize anthracnose which results in significant yield losses worldwide. We conducted a comprehensive investigation into the evolutionary genomics of C. graminicola using a collection of 212 isolates from 17 countries across five continents. Genomic analyses supported the existence of three geographically isolated genetic lineages, with a significant pattern of isolation by distance. We identified two distinct gene flow patterns, driven by short- and long-distance dispersal, likely resulting from the natural spread of the pathogen and the exchange of contaminated seeds. We present evidence of genetic introgression between lineages, suggesting a long history of recombination. We identified significant recombination events coalescing at distinct points in time, with the North American lineage displaying evidence of the most ancient recombination. Demographic modelling has indicated that North America is an intermediate between Brazil, Europe and an ancestral, unsampled source population, which is hypothesised to be Mesoamerican. Our analyses revealed that the global genomic structure of C. graminicola is shaped by geographic differentiation driven by long-distance migration and a long history of recombination and introgression. We show historical relationships amongst these lineages, identifying a potential route for fungal spread, with the North American population emerging ancestrally, followed sequentially by the Brazilian and European populations. Our research indicates that the European lineage is more virulent, which has implications for the potential emergence of new outbreaks of maize anthracnose in Europe. |

| Conteúdo: | Abstract: Few studies have addressed the sustainability of harvesting of secondary compounds from non-timber forest products (NTFP). Most of them suggest that reproductive aspects can be compromised due to competition for resource allocation. These impacts may depend on the harvest history and may be more pronounced in environments with lower resource availability. This study assessed the impact of different oleoresin harvesting intervals on the reproductive phenology of Copaifera pubiflora Benth. (Leguminosae) in two tree populations with different harvesting time spans (mid- x short-term) and resource constraints in Roraima, northern Brazilian Amazon. We evaluated the impact of different intervals of consecutive oleoresin harvest compared to a control group without harvesting. Tree populations are found in forests with different precipitation ranges: (i) an ecotonal forest at the savanna-tropical rainforest boundary (intervals: 18 months, six months; mid-term; less constrained forest), and (ii) a gallery forest within the savanna ecosystem (12 months, six months; short-term; greater constrained forest). Data on the number of trees in different phenophases and fruit abortion were obtained fortnightly for two years and ten months. The occurrence, duration, and activity (number of trees) of the phenophases were examined through circular analyses. Our results indicate that oleoresin harvest did not affect the timing and duration of reproductive events, and the interval between successive collections should be considered when designing more sustainable management practices. Long-term studies should be conducted to assess whether observed patterns are maintained and to determine the optimal oleoresin harvest interval so trees can allocate resources for defense without competing with other functions. |

| Conteúdo: | Abstract: Background: The rise of herbicide-resistant weeds like Conyza canadensis L. poses a challenge to modern agriculture, driving the need for eco-friendly alternatives. Microbial metabolites from actinobacteria species offer promising weed-control solutions. This study aims to screen and identify an actinobacteria isolate from Brazil’s Caatinga biome that produces phytotoxic metabolites and to characterize its compounds. Results: An isolate, named as Caat 7–52, was selected because of its significant phytotoxic effects against Lemna minor L. Phylogenetic analyses using six concatenated genes (gyrB, recA, rpoB, trpB, atpD and 16S rRNA) confirmed Caat 7–52’s close relationship to Streptomyces musisoli TBRC 9950T, despite phenotypical differences. Bioassay-directed isolation against L. minor revealed 3-hydroxybenzoic acid and albocycline as phytotoxins, with minimum inhibitory concentrations of 50.00 and 3.12 μg mL−1, respectively. Albocycline analogues were also detected and exhibited moderate phytotoxicity in L. minor. In addition, albocycline effectively inhibited the seed germination of C. canadensis with a minimum inhibitory concentration of 6.25 μg mL−1, marking the first report of albocycline’s phytotoxic activity. Direct use of the fermented broth selectively inhibited dicot weeds, offering a sustainable and solvent-free weed management strategy. Conclusion: The discovery of Streptomyces sp. Caat 7–52 and its metabolites, combined with the direct application of fermented broth, represents a significant advancement in sustainable weed control. This bioherbicidal approach offers an environmentally friendly alternative for managing resistant weeds like C. canadensis and supports the broader use of microbial metabolites in integrated pest management programs. |

| Conteúdo: | Abstract: Wheat and wheat flour play a vital role in global food security. There is a knowledge gap regarding the environmental impacts associated with wheat cultivation and wheat flour production in subtropical and tropical environments. As one of the world’s major grain producers, Brazil needs to identify and mitigate the environmental impacts of its agricultural products. This study aimed to (1) identify the environmental impacts of the Brazilian wheat cultivation and flour production system and (2) propose strategies to mitigate the environmental impacts. The study was conducted in Brazil’s main wheat-producing region, assessing 61 farms in the wheat cultivation, grain transport, processing, and milling processes. Environmental impacts were calculated using SimaPro 9.5.0.2 with the Ecoinvent® v3.5 database. Wheat cultivation was the primary source of environmental impacts in Brazilian wheat flour production, contributing between 67% and 98% across the categories analysed. The carbon footprint of wheat cultivation was 0.50 kg CO2eq kg wheat−1, while wheat flour production ranged from 0.67 to 0.80 kg CO2eq kg flour wheat−1. Field emissions, particularly N₂O from urea, significantly impacted the global warming potential (GWP). The grain transport had a marginal environmental impact (<1.5%), and the grain processing contributed minimally, while wheat milling had a higher impact on freshwater eutrophication potential (FEP). Replacing urea with calcium ammonium nitrate (CAN) and more productive wheat varieties reduced environmental impacts in the wheat cultivation process. The use of photovoltaic energy in grain processing and milling reduced industrial environmental impacts. Brazilian wheat flour proved to be environmentally competitive compared to production in other countries, especially in terms of carbon footprint, providing insights into wheat cultivation for subtropical and tropical environments. |

| Conteúdo: | Abstract: The quality of juice obtained by pressing grape pomace and the viability of its incorporation into whole grape juice was investigated for the first time on an industrial scale. Two pressing systems were tested: hydraulic and pneumatic and the evaluated treatments were as follows: whole grape juice (CJ - control), juice 100% from hydraulic press (HP), juice 100% from pneumatic press (PP), juice with a blend of 87% CJ + 13% HP (CJHP), and 87% CJ + 13% PP (CJPP). Analyses were conducted to determine the physicochemical profiles of the juices, levels of primary and secondary metabolites, antioxidant capacity, sensory profile, and consumer acceptability. Pressing increased the yield in the hydraulic and pneumatic systems by 20.5% and 27.3%, respectively, the concentration of phenolic compounds, especially flavanols, flavonols, and stilbenes, and the antioxidant capacity. However, HP and PP juices obtained the lowest overall sensory acceptability scores compared with the control, whereas CJPP and CJHP did not differ from CJ. The pneumatic press stood out for providing better results in juice quality and yield. In this study, the incorporation of juice from pressing grape pomace collected during the maceration stage positively influenced the product’s chemical composition without altering its sensory profile or negatively affecting its acceptance by consumers. |

| Conteúdo: | Abstract: During the past 30 years, augmentative biological control (ABC) has received increasing interest and is now applied in a large diversity of crops on many hectares in Latin America and the Caribbean. Around the year 2000 4.35 million hectares were estimated to be treated with ABC, in 2018 this had grown to 31.4 million hectares, and the estimate for 2024 was about 62 million hectares. Many factors explain this dramatic increase, the most important being (a) the development of microbial agents that are relatively cheap compared to macrobial agents, easy to produce, store and apply, and reliable, (b) the fine tuning and drastic shortening of registration procedures, (c) a change in attitude towards use of alternatives for chemical pesticides among young farmers. However, there are also factors frustrating implementation of ABC of which the most important are the lobbying activities of the synthetic pesticide industry and lack of application of the true cost principle for these pesticides which makes them unrealistically cheap. Major differences with other world regions are that in Latin America ABC is almost exclusively applied in the open field, is often not based on development of resilient systems and changed in the 21st century from mainly using macrobial control agents to increased applications with microbial control agents. |

| Conteúdo: | Abstract: Gray mold, caused by Botrytis cinerea, is a primary disease affecting rose production and leads to significant post-harvest losses. This study evaluated the potential of seven bacterial species to control B. cinerea and extend the post-harvest longevity of cut roses. In vitro tests assessed the production of diffusible and volatile antifungal metabolites. Four strains (Bacillus acidiceler, Bacillus subtilis, Bacillus pumilus, and Staphylococcus equorum) were selected based on their efficacy and applied to roses of the cultivar “Tonight” at harvest. Roses treated with bacteria were inoculated with B. cinerea to evaluate disease control and stem durability. B. acidiceler, B. subtilis, and B. pumilus effectively suppressed disease symptoms and increased floral stem durability by up to two days compared to controls. Scanning electron microscopy revealed pathogen inhibition through bacterial colonization and petal biofilm formation. This study highlights the potential of beneficial bacteria as sustainable alternatives to chemical fungicides for post-harvest disease management in roses. |

However, the absence of standardized tests, specifically designed for these new methods, prompts concerns about performance consistency and transparency in the marketplace. This discussion paper underscores the critical factors that influence predictive performance and stresses the need for proficiency tests tailored to sensor-based techniques. It also highlights the significance of error metrics for accurate interpretation. Establishing robust proficiency tests is crucial for ensuring reliable soil analysis services and promoting the adoption of best practices in this technology. |

| Conteúdo: | Abstract: Atmospheric CO2 concentrations in urban areas reflect a combination of fossil fuel emissions and biogenic fluxes, offering a potential approach to assess city climate policies. However, atmospheric models used to simulate urban CO2 plumes face significant uncertainties, particularly in complex urban environments with dense populations and vegetation. This study addresses these challenges by analyzing CO2 dynamics in the Metropolitan Area of São Paulo (MASP) using the Weather Research and Forecasting model with Chemistry (WRF-Chem). Simulations were evaluated against ground-based observations from the METROCLIMA network, the first greenhouse gas monitoring network in South America, and column concentrations (XCO2) from the OCO-2 satellite spanning February to August 2019. To improve biogenic fluxes, we optimized parameters in the Vegetation Photosynthesis and Respiration Model (VPRM) using eddy covariance flux measurements for key vegetation types, including the Atlantic Forest, Cerrado, and sugarcane. Results show that at the urban site (IAG), the model consistently underestimated CO2 concentrations, with a negative mean bias of −9 ppm throughout the simulation period, likely due to the complexity of vehicular emissions and urban dynamics. In contrast, at the vegetated site (PDJ), simulations showed a consistent positive mean bias of 5 ppm and closely matched observations. Seasonal analyses revealed higher CO2 concentrations in winter, driven by greater atmospheric stability and reduced vegetation uptake estimated by VPRM, while summer exhibited lower levels due to increased mixing and higher agricultural productivity. A comparison of biogenic and anthropogenic scenarios highlights the need for integrated emission modeling and improved representation of biogenic fluxes, anthropogenic emissions, and boundary conditions for high-resolution modeling in tropical regions. |

| Conteúdo: | Abstract: Sugarcane is a major tropical C4 crop of global economic significance, primarily used for sugar, ethanol, and bioenergy production. As climate change accelerates, with projected increases in global temperatures, understanding the temperature sensitivity of sugarcane’s radiation use efficiency (RUE) is crucial for projecting yield under changing environmental conditions. In this context, this study aimed to characterize sugarcane RUE response to temperature across various environments and varieties from key producing regions worldwide. Using experimental data from six countries (Brazil, South Africa, United States of America, Zimbabwe, Argentina, and La Réunion) and 40 distinct varieties, our results indicated that maximum RUE (RUEMAX) is consistent across varieties, while apparent RUE (RUEA) showed significant variation. Based on this diverse dataset, we parameterized different RUEMAX temperature response formalisms used in crop models (APSIM-Sugar, DSSAT-Canegro, MOSICAS, and emergent formalisms). We compared their ability to simulate RUEA in various regions accurately. Our analysis revealed significant differences in formalism performance, emphasizing the need for accurate parameterization. Additionally, we demonstrated that predictions of biomass production under climate change scenarios are highly sensitive to the formalism parameterization used to represent the RUE-temperature relationship. These findings highlight the critical importance of refining crop models considering temperature response and cardinal temperatures (optimal range: 30–33°C) to enhance projections of sugarcane yield under future climate conditions. We discussed physiological processes that may explain differences in RUEA among varieties. Incorporating these refined mechanisms into models will support more accurate climate impact assessments and aid breeding programs focused on developing high-yield sugarcane varieties. |

| Conteúdo: | Abstract: Background: During the Green Revolution, one of the biggest developments of wheat domestication was the development of new cultivars that respond well to fertilisers and produce higher yields on shorter stems to prevent lodging. Consequently, this change has also impacted the wheat microbiome, often resulting in reduced selection of taxa and a loss of network complexity in the rhizospheres of modern cultivars. Given the importance of rhizosphere microbiomes for plant health and performance, it is imperative that we understand if and how these changes have affected their function. Here, we use shotgun metagenomics to classify the functional potential of prokaryote communities from the rhizospheres of pre-green revolution (heritage) cultivars to compare the impact of modern wheat breeding on rhizosphere microbiome functions. Results: We found distinct taxonomic and functional differences between heritage and modern wheat rhizosphere communities and identified that modern wheat microbiomes were less distinct from the communities in the surrounding soil. Of the 113 functional genes that were differentially abundant between heritage and modern cultivars, 95% were depleted in modern cultivars and 65% of differentially abundant reads best mapped to genes involved in staurosporine biosynthesis (antibiotic product), plant cell wall degradation (microbial mediation of plant root architecture, overwintering energy source for microbes) and sphingolipid metabolism (signal bioactive molecules). Conclusions: Overall, our findings indicate that green revolution breeding has developed wheat cultivars with a reduced rhizosphere effect. The consequences of this are likely detrimental to the development of microbiome-assisted agriculture which will require a strong rhizosphere selective environment for the establishment of a beneficial plant root microbiome. We believe our results are of striking importance and highlight that implementation of microbiome facilitated agriculture will benefit from deliberately incorporating the development of beneficial plant-microbiome interactions, alongside traditional yield traits, to advance sustainable wheat production. |

| Conteúdo: | Abstract: In laboratory trials, sulfluramid (N-ethyl perfluorooctane sulfonamide; EtFOSA) has been shown to degrade into perfluorooctanesulfonic acid (PFOS) under aerobic conditions, including in Brazilian agricultural soils. Thus, we aimed to investigate the environmental occurrence of PFOS in agricultural areas mostly used for forestry, where sulfluramid-based ant baits are primarily used. Surface water, groundwater, and sediment samples were collected from selected micro-watersheds, primarily used for forest plantation, and PFOS and its precursors were assessed by ultra-performance liquid chromatography coupled to a triple quadrupole mass spectrometer. PFOS was the most frequently detected compound, present in 76 % of surface water samples, with concentrations up to 50.6 ng L−1. EtFOSA and perfluorooctane sulfonamide (FOSA) were also detected, but at lower frequencies and concentrations. The highest PFOS concentrations were found in the watershed with mixed urban/industrial and agricultural activities, indicating multiple contamination sources. However, groundwater samples from monitoring wells inside planted forests of Pine and Eucalyptus also showed detectable PFOS contamination, likely due to the biodegradation of EtFOSA from ant bait applications. Sediment samples revealed seasonal variations, with higher detection rates during the dry season, suggesting a high-mobility of the studied compounds. Risk assessment using the risk quotient (RQ) approach indicated that all measured PFOS concentrations exceeded the European Union\\\'s annual average environmental quality standard (AA-EQS) for inland surface waters, posing potential risks to aquatic biota. This study endorses the need for ongoing monitoring, regulations, and safer pest control alternatives to mitigate PFOS contamination and its environmental risks. |

| Conteúdo: | Abstract: Accurately estimating direct land use change (DLUC) greenhouse gas (GHG) emissions remains a major challenge for agricultural GHG inventories and life cycle assessment. Given their relevance and agricultural production in Brazil, this study addresses critical data gaps in DLUC CO2 accounting for Brazilian agriculture. It adds to existing frameworks by estimating and quantifying the uncertainties of carbon stocks at the municipality level for 44 land use combinations and the DLUC-CO2 balance for 64 crops, pasture, and planted forest. The methodology follows IPCC guidelines and the Brazilian Land Use Change (BRLUC) method. It employs the stock-difference approach, implemented in the BRLUC tool, using Tier 1 and 2 best available data (e.g., biomass carbon stocks) alongside land conversion patterns (MapBiomas), with uncertainties propagated via 10,000 Monte Carlo simulations. Results highlight substantial geographical variation in carbon stocks and high uncertainties that often prevent statistically significant differentiation between management practices. The national average DLUC-CO2 balance (tCO2.ha−1.yr−1±95 %CI) exhibits considerable uncertainty. Net emissions were estimated for soybean (1.7 ± 0.8), corn (2.1 ± 0.8), and pasture (4.2 ± 1.5), while net removals were observed for coffee (−4.7 ± 2.6). For some land uses, balances can range from emissions to removals—for example, sugarcane (−0.3 to 0.4 tCO2.ha−1.yr−1) and planted forests (−3.3 to 2.2 tCO2.ha−1.yr−1). We recommend that DLUC-CO2 accounting or interpreting the results cautiously. To reduce uncertainties, future efforts should prioritize improving precision, spatial resolution, and coverage of carbon stock data. |

| Conteúdo: | Abstract: Soil microbial diversity plays a crucial role in plant health, influencing pathogen suppression and biocontrol efficacy. This study investigated how soil microbial diversity modulates interactions between the pathogen Bipolaris sorokiniana and the biocontrol bacterium Pseudomonas inefficax in the wheat rhizosphere. Using a dilution-to-extinction method, we established five soil microbial diversity levels: natural soil, dilutions at 10-1, 10-3, 10-6, and fully autoclaved soil. This gradient allowed us to evaluate disease severity, plant growth, and rhizosphere microbiome shifts. Inoculation with Pseudomonas inefficax significantly reduced disease severity caused by Bipolaris sorokiniana, particularly in low-diversity soils, emphasizing the effectiveness of P. inefficax in these simplified environments where microbial competition is reduced. Despite higher pathogen abundance in low-diversity soils, P. inefficax effectively mitigated disease severity, likely through direct antagonistic activity. Alpha diversity indices confirmed a reduction in microbial diversity across the gradient, while beta diversity analyses revealed distinct shifts among treatments. Although Chitinophaga, Pseudomonas and Dyadobacter were significantly enriched in natural soils with inoculation of the P. inefficax, statistically significant disease suppression was not observed under these higher-diversity conditions. On the other hand, in low-diverse soils (autoclaved soil), where disease is suppressed with P. inefficax inoculation, Fluviicola showed a significant enrichment when compared with the treatment inoculated only with the pathogen, suggesting that this bacterial taxon can play a role in disease suppression along with the inoculant. These findings underscore the critical role of the soil microbial diversity in shaping the success of biocontrol interventions. |

| Conteúdo: | Abstract: Rhipicephalus microplus, commonly known as the cattle tick, is responsible for causing severe economic losses in livestock production in several countries. The utilization of entomopathogens in infested pastures may represent a sustainable and eco-friendly alternative for tick control. This study evaluated the effectiveness of combining entomopathogenic fungi (EPF, Metarhizium spp.) and entomopathogenic nematodes (EPN, Heterorhabditis bacteriophora) for controlling R. microplus. Laboratory assays tested sub-doses of M. robertsii IP 146 conidia in combination with H. bacteriophora HP88 infective juveniles against engorged females of R. microplus, whereas field trials assessed a granular formulation containing M. robertsii microsclerotia applied with H. bacteriophora infective juveniles in infested field plots to target the tick’s non-parasitic phase during rainy and dry seasons. In laboratory experiments, the co-application of fungal sub-doses and nematodes demonstrated synergistic effects, significantly enhancing tick control. Field applications during the rainy season achieved tick population reductions of 54.09% (M. robertsii), 38.11% (H. bacteriophora), and 46.72% (combination). During the dry season, only the fungal formulation significantly reduced tick populations, with 26.27% efficacy. These findings underscore the potential of EPF and EPN, either singly or in combination, as complementary tools to traditional chemical methods for sustainable cattle tick management. |

| Conteúdo: | Abstract: Coffee demand continues to rise, while producing countries face increasing challenges and yield losses due to climate change. In response, farmers are adopting agricultural practices capable of boosting productivity. However, these practices increase intercrop variability, making coffee mapping more challenging. In this study, a novel approach is proposed to identify coffee cultivation considering four phenological stages: planting (PL), producing (PR), skeleton pruning (SK), and renovation with stumping (ST). A hierarchical classification framework was designed to isolate coffee pixels and identify their respective stages in one of Brazil’s most important coffee-producing regions. A dense time series of multispectral bands, spectral indices, and texture metrics derived from Harmonized Landsat Sentinel-2 (HLS) imagery, with an average revisit time of ~3 days, was employed.This data was combined with an ensemble learning approach based on decision-tree algorithms, specifically Random Forest (RF) and Extreme Gradient Boosting (XGBoost). The results achieved unprecedented sensitivity and specificity for coffee plantation detection with RF, consistently exceeding 95%. The classification of coffee phenological stages showed balanced accuracies of 77% (ST) and from 93% to 95% for the other classes. These findings are promising and provide a scalable framework to monitor climate-resilient coffee management practices. |

| Conteúdo: | Abstract: Grasslands are vital for global food security, making reliable monitoring of forage mass (FM) essential for sustainable pasture management. The availability and quality of FM are key factors in determining the profitability of pasture-based farms. This study presents a replicable methodology for estimating FM using multi-sensor satellite data and an agrometeorological modeling framework. Conducted at the Brazilian Agricultural Research Corporation Southeast Livestock Center (Embrapa Pecuária Sudeste) in São Carlos, Brazil, the research integrates NASA’s Harmonized Landsat and Sentinel-2 (HLS) imagery with climate data processed through the Simple Algorithm for Evapotranspiration Retrieving (SAFER) and Monteith’s Light Use Efficiency (LUE) models. The SAFER model explained over 67 % of FM variability in three pasture-based livestock systems. A key factor in achieving accurate FM estimates was the differentiation between field green matter (GM) and total dry matter, as GM represents the most nutritious and consumable forage component. The model performed best in extensive systems, where minimal management intervention resulted in stable forage conditions. In integrated crop-livestock systems, the accuracy remained high, though fertilization and crop residue decomposition influenced FM estimates. In intensive systems, model performance was slightly lower due to higher management variability. This study contributes to the development of automated, scalable FM assessment methods, enabling systematic pasture monitoring and data-driven grazing management. The SAFER model allowed simultaneous processing of satellite imagery and climate data, increasing the accuracy of FM estimations. Future research should explore the use of higher-resolution imagery (e.g., CBERS-4A, PlanetScope) to better capture within-field variability and consider increasing the frequency of field sampling frequency (from 32 days to 15 or even 7 days) to further improve FM estimation accuracy, particularly in intensive systems. |

| Conteúdo: | Abstract: CONTEXT: Grazing landscapes cover a substantial portion of global agricultural land and are essential for the provision of ecosystem services, food security, and rural livelihoods. The yield gap concept highlights the potential for increased agricultural production through sustainable intensification by quantifying the difference between current yields and maximum achievable yields. Assessing yield gaps is crucial for targeting public and private interventions and investments in regions with the greatest potential for production increases. However, methods for assessing yield gaps vary, impacting their ability to identify underlying factors and assess yield risks consistently and accurately, particularly in pasture-based systems where interactions between plants and animals add complexity. OBJECTIVE: The objectives of this review were to provide an overview of methods used to assess and analyze yield gaps in pasture-based livestock production systems and to discuss how they may aid decision-making processes. METHODS: Review of literature. RESULTS AND CONCLUSIONS: Different approaches have been applied for yield gap analysis of pasture-based livestock production systems. For benchmarking, climate binning, frontier methods, and production system models approaches we provide a brief description, examples of applications, data requirements, and advantages and disadvantages. The selection of specific approaches depends on the research questions addressed, spatial scale of the study, data availability and computational processing capacity. Benchmarking approaches are commonly used by farmers to compare the performance of their enterprise to others with similar characteristics. The climate binning approach is applied to larger spatial scales for identifying regions where sustainable intensification technically could be an option. Frontier approaches provide insights on both technical and economic efficiencies. Methods based on production system models may be applied for different purposes, according to the characteristics of the models. In general, mathematical models currently used for yield gap analysis in pasture-based production systems rarely account for the effects of different grazing strategies, plant species proportion, pasture nutritive value and selective grazing by animals. SIGNIFICANCE: Methods for yield gap assessment and analysis in pasture-based systems can contribute knowledge and technical conditions to increase productivity and resource use efficiency from existing areas rather than expanding to new ones. This provides opportunities to meet the increasing demand for food while conserving land and natural resources. It is necessary to integrate technical insights from yield gap analysis into a broader social, economic, and political framework to support decision making by policy makers and farmers, highlighting the need for future research to improve the current methods. |

| Conteúdo: | Abstract: ETa (actual evapotranspiration) is widely used in irrigated agriculture. Traditional methods use parameters of the soil, plant and atmosphere but depend on tabulated values and weather stations, while via remote sensing they have limitations regarding the presence of clouds. Therefore, this study aimed to train machine learning algorithms to directly estimate ETa, without the need for a weather station, using active remote sensing, which is not affected by the presence of clouds. Data were collected from areas cultivated with sugarcane in the Atlantic Forest, Caatinga and Cerrado biomes using the OLI (Operational Land Imager) and TIRS (Thermal Infrared Sensor) sensors aboard the Landsat-8 and 9 satellites. These data were used to calculate ETa using the METRIC (Mapping Evapotranspiration at High Resolution with Internalized Calibration) model, which was used as the response variable. In addition, data were collected from the SAR (Synthetic Aperture Radar) sensor aboard the Sentinel-1 satellite, as well as soil, meteorological, climatological, elevation, latitude, day of the year and astronomical information data, which were used as predictor variables in 13 machine learning algorithms. After training, the brnn and XgbTree algorithms stood out from the others, showing R2 of 0.45 and 0.46 and RMSE of 1.5 and 1.6, respectively. Despite the relatively low statistical values, it is possible to determine ETa in areas with the presence of clouds using the machine learning algorithms developed in this study and without the need for a weather station. |

| Conteúdo: | Abstract: Using managed pollinators to supplement the contributions of wild pollinators is a promising means to increase crop production and rural livelihoods sustainably. However, evidence of the efficacy of managed pollinators must be provided for many crops, especially in tropical regions. Herein, we introduced managed colonies, including Africanized honey bees (Apis mellifera) and native stingless bees (Scaptotrigona spp.), in 23 coffee fields across a gradient of native forest cover in southeastern Brazil. We found coffee yield per bush increased by 16 % in coffee fields near managed colonies compared to more distant control fields. We detected positive effects for both managed bee species, though with higher variability for the native bee species due to low replication. Our study provides robust evidence that supplementing coffee farms with managed bee colonies can increase coffee yields and should stimulate further research and investment in bee supplementation. |

| Conteúdo: | Abstract: The incorporation of organic amendments into the soil offers numerous long-term benefits. Waste from Tenebrio molitor larvae production, including feces, exoskeletons, and feed residue, can serve as a valuable organic fertilizer. However, factors such as the type of waste, application rate, decomposition stage, and soil characteristics can significantly impact plant growth. This study evaluates the effectiveness of yellow mealworm frass as a biofertilizer for tomato plants. The waste was incorporated into the soil at concentrations of 0, 1, 2, 3, 4, and 5 % (v/v) and incubated for 0, 10, and 20 days, after which ten tomato seeds were sown. Seedling emergence, as well as the fresh and dry weights of the tomato plants, were evaluated weekly. Additionally, the impact on tomato plant growth was studied under greenhouse conditions. The results indicated that yellow mealworm frass did not exhibit phytotoxicity when incubated for more than 20 days; however, phytotoxic effects were observed at shorter incubation periods (0 and 10 days). After 20 days of incubation, both the fresh and dry mass of the plants increased proportionally with the rise in waste concentration. Greenhouse experiments further revealed that yellow mealworm frass enhanced stem diameter, fresh and dry mass, net photosynthesis, and water use efficiency of tomato plants. These findings underscore the potential of yellow mealworm frass as an effective organic fertilizer in agriculture. |

| Conteúdo: | Abstract: Sphenophorus levis, commonly known as the sugarcane weevil, is one of the most important pests affecting Brazilian sugarcane crops. It has spread to all sugarcane-producing regions of Brazil, mainly through contaminated stalks. Effective control of this pest is difficult due to the protection conferred by the host plant during the larval stage. As a result, despite current control measures, S. levis populations continue to grow, and reports of new infestations remain frequent. Biotechnological control measures, such as the use of viruses, stands as a promising tool for pest control in agriculture. The aim of this study was to explore the RNA virome associated with S. levis using a viral metagenomic approach. Through the Read Annotation Tool (RAT) pipeline, we characterized, for the first time, the gut-associated viral community in adult weevils, identifying several novel viral genomes. Sphenophorus levis-associated virus (SLAV) had 12,414 nucleotides (nt); Sphenophorus levis tombus-like virus (SLTV) had 4085 nt; and the four genomic segments of Sphenophorus levis reo-like virus (SLRV) ranged from 2021 to 4386 nt. These genomes were assembled from 65,759 reads (SLAV), 114,441 reads (SLTV), and 270,384 reads (SLRV). Among the detected viral families, Partitiviridae was the most abundant. The identification of possible viral pathogens lays the foundation for future research into their potential use as biological control agents against S. levis. Resumo: O Sphenophorus levis, comumente conhecido como o gorgulho da cana-de-açúcar, é uma das pragas mais importantes que afetam as culturas brasileiras de cana-de-açúcar. Tem se espalhado para todas as regiões produtoras de cana-de-açúcar do Brasil, principalmente através de talos contaminados. O controle efetivo desta praga é difícil devido à proteção conferida pela planta hospedeira durante a fase larval. Como resultado, apesar das atuais medidas de controle, as populações de S. levis continuam a crescer, e os relatos de novas infestações continuam frequentes. Medidas de controle biotecnológico, como o uso de vírus, são uma ferramenta promissora para o controle de pragas na agricultura. O objetivo deste estudo foi explorar o viromo RNA associado a S. levis usando uma abordagem metagenômica viral. Através do pipeline Read Annotation Tool (RAT), caracterizamos, pela primeira vez, a comunidade viral associada ao intestino em graus adultos, identificando vários genomas virais novos. O vírus associado ao Sphenophorus levis (SLAV) tinha 12.414 nucleotídeos (nt); o vírus semelhante ao tombus de Sphenophorus levis (SLTV) tinha 4085 nt; e os quatro segmentos genômicos do vírus semelhante ao Sphenophorus levis (SLRV) variavam de 2021 a 4386 nt. Esses genomas foram montados a partir de 65.759 leituras (SLAV), 114.441 leituras (SLTV) e 270.384 leituras (SLRV). Entre as famílias virais detectadas, o Partitiviridae foi o mais abundante. A identificação de possíveis patógenos virais estabelece as bases para futuras pesquisas sobre seu uso potencial como agentes de controle biológico contra S. levis. |

| Conteúdo: | Abstract: Leaf-cutting ants (LCAs) of the genera Atta and Acromyrmex are major agricultural pests in the Americas, relying on their mutualism with the fungus Leucoagaricus gongylophorus for colony survival. Mycoparasites such as Trichoderma spp. offer promising biocontrol tools by antagonizing this essential symbiont. This study aimed to identify the most antagonistic isolate of Trichoderma asperelloides, elucidate its mechanisms of action against the fungal garden-symbiont L. gongylophorus, and further evaluate its indirect biocontrol activity on the health and survival of Atta sexdens mini-colonies. Isolates of T. asperelloides namely Tricho 4, Tricho 5, Tricho 7, and Tricho 11 exhibited strong antagonism, reducing L. gongylophorus colony growth by more than 94 % in dual culture assays. Additionally, antibiosis mechanism and volatile compound release by T. asperelloides induced over an 80 % reduction in L. gongylophorus growth. Moreover, exposure to these isolates significantly disrupted ant mini-colonies, leading to mortality rates of up to 60 % and a concurrent reduction in waste production, likely linked to the antagonism effects of T. asperelloides on the garden-symbiont fungus. Overall, these T. asperelloides isolates demonstrate potent antifungal activities against L. gongylophorus and may serve as a sustainable biological strategy for managing LCA colonies. |

| Conteúdo: | Abstract: Wine lees, a winemaking by-product, have high potential for reuse due to their significant phenolic content and antioxidant capacity. To preserve their composition and enhance their feasibility for incorporation into food products, this study evaluated the effects of oven drying (40 °C) and freeze-drying on the physicochemical and nutritional characteristics of malolactic lees, as well as the impact of the storage time. Samples were analyzed at 0, 45, and 90 days of storage at 25 °C under light exposure conditions. Total phenolic content was determined by Folin–Ciocalteu, antioxidant activity by DPPH and FRAP assays, and phenolic groups by HPLC-DAD-FD. Both methods preserved a high protein content (~20%), with 44.66% essential amino acids and an essential amino acid index of 1.55, indicating high-quality proteins. The freeze-dried lees showed a higher phenolic content (77.92 mg GAE/g), whereas the oven-dried lees exhibited greater antioxidant activity, likely due to the formation or release of bound phenolic compounds induced by thermal processing. Among the phenolic groups, tannins were the most favored in terms of preservation. Storage time significantly influenced the parameters evaluated, indicating the impact of drying on stability. While freeze-drying better preserved phenolic compounds, oven drying was considered the most suitable option for large-scale application. |

| Conteúdo: | Resumo: O presente artigo tem como objetivo realizar uma revisão sistemática da literatura acadêmica referente à Assistência Técnica e Extensão Rural (ATER) digital no Brasil. A metodologia adotada, de natureza qualitativa e caráter exploratório-descritivo, fundamentou-se em procedimentos de revisão sistemática, utilizando técnicas de Análise Lexical, Classificação Hierárquica Descendente e Análise Fatorial de Correspondência, por meio do software Iramuteq. Os resultados apontam que os estudos sobre a temática permanecem incipientes, com maior concentração nas regiões Sul e Sudeste do país, sendo significativamente impulsionados pelo contexto da pandemia de COVID-19. Observou-se que as pesquisas têm enfatizado o uso independente de aplicativos, redes sociais e sistemas de geoinformação pelos agricultores, ressaltando o potencial da ATER digital para ampliar o acesso a conhecimentos técnicos e intensificar a interação entre agricultores e extensionistas. Entretanto, sua efetiva implementação ainda enfrenta entraves relacionados à baixa conectividade, à ausência de políticas públicas consistentes e à dependência de superar barreiras estruturais e institucionais, configurando-se, assim, como um complemento às práticas de extensão rural tradicionais. |

| Conteúdo: | Abstract: Our study focused on the phytotoxic and antifungal activities of metabolites isolated from Fusarium sp., an endophyte associated with the medicinal plant Piper sp. Chromatographic separations of the Fusarium sp. crude extract led to the isolation of three analogous compounds: anhydrofusarubin (1), 5,10-dihydroxy-1,7-dimethoxy-3-methyl-1H-benzo[g]isochromene-6,9-dione (2), and javanicin (3). The structures of the isolated compounds were determined by high-resolution mass spectrometry (HRMS) analysis and direct comparison of 13C NMR data with that reported in the literature. The isolated compounds were evaluated for phytotoxic activity against Lactuca sativa and Agrostis stolonifera. All compounds exhibited strong phytotoxic activity on both plant species, completely inhibiting seed germination at a concentration of 1 mg mL-1. Additionally, the isolated compounds were evaluated against Lemna paucicostata, achieving a 50% growth inhibition (IC50) at concentration of 64, 28, and 31 μM for compounds 1, 2, and 3, respectively. The antifungal activity of these compounds was evaluated using a bioautography assay targeting the agricultural pathogen Colletotrichum fragariae. Among them, compound 2 demonstrated significant antifungal activity. Our results showed that tropical medicinal plants harbor an interesting endophyte that has a potential reservoir of bioactive compounds. Moreover, the structures of these compounds could serve as scaffold for the development of new pesticides. |

| Conteúdo: | Abstract: Brazil is a leading producer of multi-purpose crops—such as corn, soybean, and sugarcane—used for human consumption, animal feed, and biofuel production. This study generated agricultural inventories for these three crops based on state-level information. For sugarcane, we used primary data submitted by ethanol producers to RenovaBio. For soybean and corn, we retrieved and updated data from a previous study, which gathered information through panel consultations with farmers and sector experts. We also calculated the greenhouse gas (GHG) emissions associated with the crops using the Life Cycle Assessment (LCA) method. Our analysis revealed significant variability in emissions across states, especially for corn and sugarcane. Without considering direct land use change (dLUC), the states with the highest and lowest emissions for each crop were as follows: (i) sugarcane: Paraíba at 54 and Goiás at 37, with a national average of 42 kg CO2e/t cane; (ii) soybean: Maranhão at 344 and Minas Gerais at 300, average of 323 kg CO2e/t soy; (iii) first-crop corn: Maranhão at 416 and Mato Grosso at 264, average of 300 kg CO2e/t corn; (iv) second-crop corn: Paraná at 306 and Minas Gerais at 153, average of 255 kg CO2e/t corn. Emissions were inversely related to crop yields, with the exception of second-crop corn. In general, lower yields were observed in states of the Northeast region (e.g., Maranhão and Paraíba), which face challenges due to irregular climate patterns and water deficits. For sugarcane cultivated in the same region, emissions from straw burning had a significant impact, with the practice being applied to more than 60% of the crop area. If dLUC emissions were included, variability would increase dramatically—particularly for corn and soybean in some states—due to patterns of cropland expansion into native vegetation areas over the 2000–2019 period. In particular, total soybean emissions would range from 471 in Paraná to 2173 in Maranhão, with a national average of 1022 kg CO2e/t soy. These findings can be valuable as references for life cycle databases, for the development of state-specific emission factors for biofuels produced from the investigated crops, and as supporting information for decarbonization programs. |

| Conteúdo: | Abstract: Penicillium digitatum and Geotrichum citri-aurantii are fungi that cause green mold and sour rot, respectively, both of which are postharvest diseases responsible for economic losses in oranges. Concerns about environmental and human health regarding agrochemicals necessitate the investigation of effective disease control alternatives. This study aimed to investigate the in vitro effect of seven essential oils (EOs) on the mycelial growth of G. citri-aurantii and P. digitatum in orange, to identify the EOs with the highest antifungal activity, and to determine the minimal inhibitory concentration (MIC) of the selected EOs. Additionally, the chemical composition of two batches of EOs from the same plant species was analyzed using gas chromatography with mass spectrometry (GC–MS), and the results were compared. The antifungal activity of the mixture of the major constituents of each selected EO was evaluated. According to the results, oregano, cinnamon bark, clove basil, and rosemary pepper EOs exhibited the most promising outcomes in inhibiting G. citri-aurantii and P. digitatum, with MIC of 0.25–3.0 μL. mL−1. Despite being extracted from the same plant species, the two EO batches showed different profiles of chemical constituents and proportions. Concerning the antifungal activity of the constituents, the mixture of the three major EO constituents displayed greater antifungal activity than the pure EO, with MIC of 0.25–1.00 μL. mL−1, suggesting an interaction among the mixture components. Therefore, using a mixture of the major constituents of EO represents a promising alternative to chemical fungicides commonly used for controlling postharvest diseases in oranges. |

| Conteúdo: | Abstract: Papaya is susceptible to fungal deterioration and the use of essential oils (EOs) emerges as a promising alternative to fungicides, which causes environmental and human health problems. To evaluate the antifungal activity of essential oils and their major constituents in controlling papaya pathogens, the following in vitro assessments were conducted: I) screening of seven EOs regarding the antifungal activity; II) determination of the minimum inhibitory concentration (MIC) of the most promising EOs; III) analysis of chemical composition of the most effective oils; and IV) evaluation of the antifungal potential of the major constituents both individually or in combination. The results showed that the EOs of cinnamon bark, oregano, clove basil, and rosemary pepper exhibited high antifungal activity against all studied fungi, with MIC values from 0.50 to 2.00 μL mL-1. The major constituents found in oregano EO were carvacrol, ρ-cymene, and thymol; in cinnamon bark EO, cinnamaldehyde, o-methoxy, and cinnamyl; in rosemary pepper EO, thymol, ρ-cymene, and caryophyllene; and in clove basil EO, eugenol, ρ-cymene, and caryophyllene. Regarding the antifungal activity of the EO constituents, the mixture of the three major demonstrated greater efficiency against the studied fungi. Using constituents represents an alternative for controlling postharvest diseases in papaya. |

| Conteúdo: | Abstract: The objective of this study was to optimize the culture medium for enhanced production of Bacillus velezensis AP-3 endospores using both liquid and solid-state fermentation techniques. Additionally, the study aimed to assess the stability of endospores in powder formulations containing talc and potato starch, and to evaluate the growth-promoting effects of these formulations on bean plants. Further, we evaluated the inhibition of mycelial growth of Sclerotinia sclerotiorum and Fusarium oxysporum f. sp. lycopercisi by metabolites produced by this bacterial strain. The plant growth promotion assay evaluated these formulations across various application methods: seed treatment, sowing furrow application, and a combination of both. Adjustments to culture medium significantly influenced the endospore yield of B. velezensis. Solid-state fermentation in rice flour and potato starch yielded up to 2.06 × 108 and 1.82 × 108 CFU g− 1 after 7 days in a 60% moisture medium, respectively. Conversely, submerged fermentation in molasses + cottonseed flour medium produced 1.7 × 109 CFU mL− 1 (viable endospores) in 3 days. The powder formulations showed high stability, maintaining viability for up to 226 days at room temperature. This bacterial strain effectively inhibited the mycelial growth of target fungal pathogens and promoted bean plant growth, particularly by enhancing root development. These findings highlight the versatility of B. velezensis AP-3 in producing endospores through two fermentation methods, its extended shelf-life as a wettable powder formulation, and its efficacy both as biocontrol agent and plant growth promoter, contributing to a sustainable agriculture. |

| Conteúdo: | Abstract: Gibberellic acid (GA3) may help to synchronize coffee flowering, whilst ethylene (in the form of Ethephon) may assist in advancing coffee berry maturation even when applied in the pre-flowering stage of phenophase. Functional–structural plant modeling (FSPM) can be used to help understand whole-plant responses, such as plant-scale photosynthesis. FSPM has never been used to investigate the response of coffee plants to external plant growth regulator (PGR) applications. We hypothesized that treatment with PGRs at the beginning of berry maturation (BM) during phenophase could (1) influence plant leaf area and plant photosynthesis at the end of BM and (2) assist in the uniformity of the berry maturation of seven-year-old coffee plants. Additionally, we assumed that (3) the distribution of berries over the vertical plant profile could be related to the coffee beans’ chemical quality, and that irrigated plants would have delayed maturation, but a higher yield than non-irrigated (NI) plants. To test these hypotheses, a short sustainable period of irrigation was applied six weeks before harvest. Irrigated plants were treated with GA3 or Ethephon. A combination of field measurements (leaf gas exchanges, berry collection and bean chemical analyses in relation to vertical plant strata) and computer modeling were used. At the beginning or the end of BM, coffee trees were coded using the VPlants modeling platform and reconstructed using CoffePlant3D software to compute the plant leaf area and plant photosynthesis. The greatest number of second-order red berries were found in the upper stratum, S3 (>160 cm), while slightly fewer were found in S2 (80–160 cm) belonging to the third-order axes, and the lowest number was found in S1 (<80 cm). Green berries were more representative in S2, with the greatest number belonging to the third-order axes. The participation of third-order axes in berry yield was up to approximately 37% for red berries and 25% for green berries. The greatest separation between PGRs could be seen in S2, where more berries in the Ethephon-treated plants were found than in the GA3 treated ones, while the dry mass (DM) percentage was higher in GA3 than in the Ethephon treatment. The percentage of DM in fresh mass was 17–28% in the green berries and 28–36% in the red berries. PGRs were important for homogenous berry maturity, especially GA3, which also showed the lowest total chlorogenic acid content. The NI plants showed reduced red and total berry production when compared to irrigated ones, indicating this horticultural measure is important, even during a sustainably reduced six-week period, due to preserved leaf area and plant photosynthesis, and it also increased the lipid and kahweol contents of irrigated plants when compared to NI plants, despite the maturation delay. |

| Conteúdo: | Abstract: Dioecious species show a division of labor expressed through the differentiated manifestation of resource acquisition. We hypothesized that the expression of secondary sexual dimorphism (SSD) in the leaf gas exchange of yerba mate would be more intensive in females than in males to permit females the carbon investments necessary to finish the reproductive cycle. This species can present two growth units annually (GU1-fall and GU2-spring) intercalated with two rest periods (R1-summer and R2-winter). The leaf area index (LAI) and the diurnal courses of leaf photosynthesis (Anet), stomatal conductance (gs), leaf transpiration (E), intercellular CO2 concentration (Ci), water use efficiency (WUE), and instantaneous carboxylation efficiency (Anet/Ci) were estimated in female and male plants of yerba mate during four periods of annual rhythmic growth in monoculture (MO) and agroforestry (AFS). Leaf gas exchanges varied over the annual rhythmic growth and were more intensive under MO than under AFS. Anet, Anet/Ci ratios, and WUE were higher in females than in males during the summer (R1) and spring (GU2). Also, gs and E were more intensive in females than males during the summer. Oppositely, higher WUE in males than in females was observed during the fall (GU1) and winter (R2), with males also showing a higher Anet/Ci ratio during the winter and higher E during the spring (GU2). Despite the strong effect of the cultivation system on LAI and leaf gas exchange traits over the diurnal course, SSD expression was rarely modified by the cultivation system, being expressed only in MO for E during the spring (GU2) and WUE during the winter (R2). High WUE in males during the winter would benefit plants during cold and dry periods, improving the balance between carbon acquisition and water loss through transpiration. On the other hand, high Anet during the summer and spring could be considered as a general fitness strategy of female plants to improve photoassimilate supply and support their additional reproduction costs. |

| Conteúdo: | Abstract: Hops (Humulus lupulus (L.) have been cultivated in Brazil, the world’s third‐largest beer producer, to meet the growing demand of its expanding brewing industry. Despite advances in agricultural practices, research on the sustainability of tropicalizing hop production remains limited. This study evaluates the social and environmental impacts of hop production in 10 reference farms across the Brazilian states of Alagoas, Goiás, and São Paulo using the Ambitec‐Agro tool. This tool assesses the impacts generated by technological innovations adopted in rural environments through change coefficients incorporated into multicriteria indicators, with weights assigned based on the spatial scale of impact occurrence within the farms. Impact indices were calculated across seven aspects: technology efficiency, environmental quality, customer respect, employment, income, health, and management and governance. These aspects were integrated into 27 criteria and 148 indicators. The results indicate positive outcomes across most criteria, with occasional temporary negative results related to energy consumption; use of agricultural inputs and raw materials; water consumption; occupational safety and health; and atmospheric emissions. To address these issues, farmers have invested in solar panels to reduce energy consumption and support other crops, implemented fertigation to improve water and input efficiency, promoted the safe use of protective equipment, and implemented green manure to store carbon. Additionally, hop production has contributed to economic growth by generating income, creating jobs, and promoting gender and generational equality, while also fostering the production of a high‐added‐value product for the Brazilian agroindustry. |

| Conteúdo: | Abstract:Umbu is a native Brazilian fruit that is underutilized and has experienced post-harvest production losses. This study aimed to evaluate the bioactive and aroma potential of umbu pulp using a metabolomics and flavoromics approach. The extractable and non-extractable phenolic compounds were analyzed by LC-DAD-ESI-QToF-MS. The antioxidant activity of umbu was evaluated against four reactive oxygen species (H2O2, ABTS•+, •OH and ROO•). The volatile and aroma profile evaluation was carried out using gas chromatography associated with olfactometry, flame ionization detector, and quadrupole mass spectrometry (GC-O-FID/qMS). A total of 19 phenolic compounds and 1 organic acid were identified in umbu pulp. The extractable phenolics found in greater quantities were (µg g− 1 dry weight, DW): myricetin (11.07), quercetin hexoside (8.40), epicatechin (7.43), rutin (7.43), and kaempferol (6.24). The non-extractable fraction accounted for 82% of the total polyphenol content and its major compounds were (µg g− 1 DW) catechin (147.08) and caffeic acid (29.53). Both fractions presented antioxidant activity against H2O2, ABTS•+, •OH and ROO•. Regarding the volatile profile evaluated by HS-SPME-GC/qMS, 2,3-butanediol and phenylethyl alcohol were found at the highest concentrations. Citrus, floral and sweet odors of p-cymene, citral, β-linalool and nerol were predominant. The bioactive and aroma potential revealed possibilities for better use of umbu pulp as a raw material/ingredient for the food, beverage, and cosmetics industries. |

| Conteúdo: | Abstract: This study aimed to evaluate the dynamics of total carbon (TC), total nitrogen (TN), total phosphorus (TP), and some indicators of environmental sustainability of Nile tilapia reared in a biofloc technology (BFT) system. Nile tilapia fingerlings were cultured in three BFT units of production (4.2 m3 each) at a stocking density of 395 fish/m3. After 70 days, the survival rate was 98.05%, with a final average weight of 20.43 g, and apparent feed conversion of 1.05. Nutrient inputs were from supply water, initial fish biomass, and feed; outputs were measured from the final fish biomass and effluent. TC, TN, and TP concentrations in the water increased linearly over time (p < 0.001) by 1.54, 1.66, and 0.44 mg/L, respectively. Feed contributed over 88% of nutrient inputs, while fish final biomass accounted for over 50% of output. Nutrient retention in fish final biomass was 29.74% (TC), 45.38% (TN), and 46.34% (TP). The system had low eutrophication potential, estimated at 57.39 kg TC, 20.02 kg TN, and 5.70 kg TP per ton of fish. Water use was minimal (0.0074 m3/ton), but energy demand was high (114.59 MJ/kg). The closed system reduces biodiversity risks by preventing fish escape. In conclusion, BFT supports high fish productivity with efficient nutrient use, minimal water use, and limited environmental impact, contributing to environmentally sustainable aquaculture. |

| Conteúdo: | Abstract: Genetic engineering of entomopathogenic fungi combined with fast-acting infective blastospores grown by liquid fermentation offers an innovative approach to develop more efficient mycoinsecticides targeting a broad spectrum of arthropod pests, thus minimizing the over-reliance on synthetic chemical insecticides. In this research, Beauveria bassiana (Ascomycota: Cordycipitaceae) was genetically engineered by integrating multiple copies of an endogenously derived Chit1 gene, which encodes a constitutively expressed chitinase putatively involved in insect cuticle degradation, into its genome, with the aim at enhancing blastospore virulence. Genomic analysis of two highly virulent mutants overexpressing Chit1 identified 4 and 2 copies of this gene in their genomes, designated as OEBbChit1-3 and OEBbChit1-5, which were significantly upregulated by approximately ∼ 3- to 5-fold higher compared to the wild-type (WT) strain, thus confirming elevated gene expression and chitinase activity consistent with overexpression of the target gene. Compared with the WT, the median time to lethality (LT50) of the OEBbChit1 mutants was shortened to 75.7 %, and the median lethal concentration (LC50) decreased approximately 4.6-log10 fold when blastospores were applied to Galleria mellonella larvae via the natural cuticle infection route. Among the phenotypic traits examined, oxidative stress was more pronounced in the highly virulent mutants, which exhibited slightly reduced blastospore production in vitro than the WT strain. Moreover, infections by the highly virulent mutants increased the density of total hemocytes relative to the WT and mock control, thus triggering a rapid insect immune response. Collectively, our findings provide compelling evidence of an innovative strategy based on the genetic improvement of B. bassiana by overexpression of the native chitinase in fast-acting blastospores, thus leading to enhanced virulence with minimal detrimental phenotypical effects in fungal development. |

| Conteúdo: | Abstract: Microbial transplantation represents a sustainable strategy to address productivity gaps in agricultural soils by transferring microbiomes that enhance nutrient cycling, pathogen suppression, and stress tolerance. This study evaluates whether probiotic consortia from high-yield soybean soils (donor soil) could improve crop performance in less productive fields (recipient soil). We developed a host-adapted inoculant from soybean rhizospheres grown in donor soil and applied it to seeds at five concentrations (0.25–10 g/kg seed) in recipient soil, with untreated controls for comparison. To assess crop-specific microbial recruitment, we prepared a parallel bean-derived inoculant under identical conditions. Through 16S rRNA sequencing and growth/yield analysis, we found the following: (1) Distinct bacteriome assemblies between soybean- and bean-derived inoculants, confirming host specificity; (2) Successful enrichment of beneficial taxa (Enterobacteriaceae increased by 15–22%, Rhizobiaceae by 7–12%) despite native community resilience; and (3) Consistent yield improvement trends (4.8–6.2%), demonstrating potential to bridge productivity gaps. These results show that transplanted microbiomes can effectively modulate rhizosphere communities while maintaining ecological balance. This work establishes a scalable approach to address soil productivity limitations through microbiome transplantation. Future research should optimize (a) inoculant composition for specific productivity gaps; (b) delivery systems; and (c) compatibility with resident microbiomes, particularly in systems where niche-specific processes govern microbial establishment. |

| Conteúdo: | Abstract: This study explored the impact of high pH and short maceration on red wines’ physical and chemical traits and stability. Specifically, wines from Petit verdot, Merlot, Malbec and Tempranillo grapes, harvested in a tropical wine-producing region, were analysed. A consistent maceration period of 96 hours was applied in all vinification trials. After six months of bottling, parameters such as colour, acetaldehyde levels, higher alcohols and phenolic compounds were assessed. The findings highlighted significant impacts of grape pH on chemical stability, influenced by the phenolic profile of each grape variety. The short maceration period reduced phenolic compound extraction in high-pH musts, leading to decreased antioxidant potential and chemical stability. Critical indicators included colorimetric parameters, acetaldehyde and free SO₂ content. Acetaldehyde levels were strongly correlated with free SO₂ consumption and colour variations, signifying oxidative processes. Wines with higher concentrations of (+)-catechin, procyanidins and monomeric anthocyanins exhibited enhanced stability, while the presence of hydroxycinnamic acids was associated with oxidative changes. Caffeic acid emerged as a potential marker of oxidative stress, particularly in grapes from warmer climates. To improve the stability of wines made from high-pH grapes, extended maceration times or increased SO₂ dosages may be required. |

This study explored the potential of five commercial probiotics - Colostrum® BS Liquid, Colostrum® BS Powder, Colostrum® BIO 21 Liquid, and Colostrum® BIO 21 MIX Powder (widely used in poultry production), and Enterogermina® (used for humans) in managing coffee leaf rust (CLR), brown eye spot (BES), bacterial leaf blight (BHB) and dieback, as well as their effect on coffee seedlings growth. In vitro experiments revealed that only Colostrum® BIO 21 Liquid completely inhibited urediniospores germination of Hemileia vastatrix, CLR causal agent, while the other probiotics showed partial inhibition. Colostrum® BS Powder, partially inhibited Cercospora coffeicola (BES causal agent) and Boeremia coffea (dieback causal agent) mycelial growth. Colostrum® BS Powder and Colostrum® BIO 21 MIX Powder, containing Bacillus sp. and lactic acid bacteria, significantly reduced the severity of CLR, dieback and showed some effectiveness against BHB (caused by Pseudomonas syringae pv. garcae). None of the tested probiotics reduced BES severity. Beyond disease control, Colostrum® BS Powder and Colostrum® BIO 21 MIX Powder consistently enhanced coffee seedling growth parameters, including shoot and root biomass, root volume, and leaf characteristics, in both cell trays and rhizotrons. Conversely, liquid formulations and Enterogermina® generally did not show significant benefits for disease control or plant growth promotion. These findings suggest that Colostrum® BS Powder and Colostrum® BIO 21 MIX Powder, that are safe for the environment and have their mass production well developed, could offer a promising, eco-friendly approach to enhancing plant health and coffee seedling growth. After further studies in field conditions they can become important tools to improve sustainable coffee production. |

| Conteúdo: | Abstract: Soil bulk density (BD) is a critical variable in the estimation of carbon (C) stocks, which are central to agriculture-based C projects. However, field sampling of BD is often labor-intensive and costly. Pedotransfer functions (PTFs), which estimate BD from easily measured soil attributes, provide a promising alternative. This study evaluated 6941 observations from plots under grain production (GR) and 1246 from native vegetation (NV), sampled down to 1 m depth across 47 farms in the South-Central region of Brazil. Each observation included BD and the contents of sand, silt, clay, and C. Thirty-three PTFs from the international literature were tested, and four new ones (F34, F35, F36, F37) were developed. Function performance was assessed using the correlation coefficient (r), function efficiency (FE), mean error (ME), and root mean square error (RMSE). Two literature-based PTFs and the four developed in this study achieved the best performance, with RMSE ranging from 0.11 to 0.20 and ME from −0.01 to 0.09. Among them, F36 and F37 showed the strongest predictive ability, with FE values of 0.41 and 0.66 and r of 0.74 and 0.81, respectively. Carbon stocks estimated from BD predicted by the selected PTFs were strongly correlated with measured stocks (r > 0.90), demonstrating that these functions are reliable alternatives to direct BD measurements for estimating C stocks. For conservative application in C projects, function F37 is recommended for layers below 30 cm, while BD should continue to be directly measured in shallower layers, where management practices exert stronger influence. |

| Conteúdo: | Abstract: Thermovinification has emerged as a rising alternative method in red wine production, gaining popularity among winemakers. The use of autochthonous yeasts isolated from grapes is also an interesting practice that contributes to the creation of wine with a distinctive regional character. This research investigated how combining thermovinification with autochthonous yeast strains influences the fermentation dynamics of Syrah wine. Six treatments were conducted, combining the use of commercial and two autochthonous yeasts with traditional vinification (7-day maceration) and thermovinification (65 °C for 2 h) processes. Sugars and alcohols were quantified during alcoholic fermentation by high-performance liquid chromatography with refractive index detection. Cell viability and kinetic parameters, such as ethanol formation rate and sugar consumption, were also evaluated. The Syrah wine’s composition was characterized by classical wine analyses (OIV procedures). The results showed that cell viability was unaffected by thermovinification. Thermovinification associated with autochthonous yeasts improved the efficiency of alcoholic fermentation. Thermovinified wines also yielded a higher alcohol content (13.9%). Future studies should investigate how thermovinification associated with autochthonous yeasts affects the metabolomic and flavoromic properties of Syrah wine and product acceptability. |

| Conteúdo: | Abstract: Clonostachys rosea is a necrotrophic mycoparasite studied for biocontrol of plant pathogenic fungi, including Botrytis cinerea, the causal agent of gray mold that causes economic losses in several common fruits and vegetables. This study evaluated how the culture aeration, manipulated through the medium‐to‐flask volume ratio, affects the submerged production of conidia and microsclerotia, key propagules for disease control. A low medium‐to‐flask ratio (1:5), which enhances aeration, significantly increased propagule yields. A high C:N ratio (50:1) favored submerged conidia production under elevated aeration, while microsclerotia formed only with low C:N (10:1) and boosted under high aeration. These propagules, along with cell‐free culture filtrates, were formulated into water‐dispersible microgranules and tested for efficacy against gray mold on cherry tomatoes. All formulations reduced disease incidence. UPLC ESI–QTOF–MS analysis of the organic extract from the culture filtrate revealed sorbicillinoids as the major antifungal metabolites. Overall, this study highlights the role of aeration in optimizing C. rosea submerged cultivation and supports the potential of its propagules and metabolites for use in biocontrol strategies against postharvest disease induced by B. cinerea. |

| Conteúdo: | Abstract: Inflammation and oxidative stress are the main mortality mechanisms caused by SARS-CoV-19. Grape juice has anti-inflammatory and antioxidant properties, which are believed to be beneficial in treating COVID-19. This randomized clinical trial evaluated the impact of grape juice supplementation in the treatment of patients with COVID-19. Thirty-six patients were randomized to the grape juice supplementation group (GJG, n = 20; 10 ml/kg/day) or the control group (CG, n = 16), which received conventional COVID-19 treatment protocols. Blood samples were collected at admission and discharge for analysis of oxidative stress markers. CBC, C-reactive protein levels, electrolytes and markers of renal function were obtained from medical records. Handgrip strength was also measured to assess muscle strength. The GJG presented significantly lower levels of C-reactive protein compared to the CG (16.35 ± 26.81 vs 56.51 ± 73.29, respectively) with an intragroup decrease in C-reactive protein after the procedures (p = 0.010). The strength of the non-dominant hand in the GJG improved in relation to pre-intervention levels and in the CG after the procedures (p < 0.05), there was a significantly shorter time of hospitalization for the GJG compared to the CG (6.85 ± 3.16 vs 9.94 ± 5.69 days, respectively). The addition of grape juice during COVID-19 treatment reduced inflammation levels and length of hospital stay, as well as increased upper limb functional strength inCOVID-19 patients.

| Conteúdo: | Abstract: Mapping banana and peach palm in heterogeneous landscapes remains challenging due to spatial heterogeneity, spectral similarities between crops and native vegetation, and persistent cloud cover. This study focused on the municipality of Jacupiranga, located within the Ribeira Valley region and surrounded by the Atlantic Forest, which is home to one of Brazil’s largest remaining continuous forest areas. More than 99% of Jacupiranga’s agricultural output in the 21st century came from bananas (Musa spp.) and peach palms (Bactris gasipaes), underscoring the importance of perennial crops to the local economy and traditional communities. Using a time series of vegetation indices from Sentinel-2 imagery combined with field and remote data, we used a hierarchical classification method to map where these two crops are cultivated. The Random Forest classifier fed with 10 m resolution images enabled the detection of intricate agricultural mosaics that are typical of family farming systems and improved class separability between perennial and nonperennial crops and banana and peach palm. These results show how combining geographic information systems, data analysis, and remote sensing can improve digital agriculture, rural management, and sustainable agricultural development in socio-environmentally important areas. |

| Conteúdo: | Abstract: Lipopolysaccharides (LPS) are structural components of gram-negative bacteria that potentially induce innate immune responses in plants. A previous study demonstrated that an LPS acts as an elicitor, triggering systemic resistance against bacterial spot in tomato caused by Xanthomonas euvesicatoria pv. perforans. However, its long-term impact on plant growth, disease control and productivity remained unclear. The first experiment determined the optimal concentration of the crude LPS for effective bacterial spot control without deleterious effects on plants. The second experiment evaluated LPS application methods and timings that provide balanced benefits for plant growth, productivity and control of bacterial spot and powdery mildew. Additionally, the involvement of polyphenoloxidase and phenylalanine ammonia-lyase (PAL) in disease resistance was also investigated through gene expression assays. Results estimated 7.3 μg/mL as the optimal dose for minimising disease severity without compromising chlorophyll content. At least one application in the vegetative stage, using either electrostatic spraying or soil dispensing, yielded the most balanced outcomes for plant growth, productivity and disease control. Electrostatic spraying provided an average reduction in severity of 60% for bacterial spot and 32% for powdery mildew, while soil dispensing provided 58% and 28%, respectively. These treatments also promoted increased PAL gene expression, suggesting that this enzyme is involved in the resistance response. |

| Conteúdo: | Abstract: The recent IPCC reports have shown that climate crises are intensifying in the third decade of the 21st century; therefore, policies based on socioeconomic and ecological sustainability must be urgently executed. However, the production organization models and results differ significantly between countries. This paper aims to compare the organic production systems of Denmark, a successful organic player, and Brazil, which has great potential but is poorly structured. Methodologically, due to the lack of quantitative data on the Brazilian organic sector, a qualitative method (SWOT Analysis) was employed to evaluate the Strengths, Weaknesses, Opportunities, and Threats of Danish and Brazilian organic agriculture. Subsequently, eleven criteria were proposed to construct a factorial space in a quadrant system for evaluating scenarios of virtuous and vicious circles. The results have shown that in Denmark, a virtuous circle of interaction between public and private agents has led the country into the global spotlight. In contrast, a vicious circle in Brazil generates obstacles that hinder the growth of organic production. Therefore, identifying these limiting circles also creates opportunities for change, such as recommending actions and public policies to overcome the limitations of Brazil’s organic sector. These findings have implications for Denmark and Brazil and can be replicated in Latin American and African countries, contributing to the global effort to enlarge sustainable food production. |

| Conteúdo: | Abstract: The cultivation of conventional maize in refuge areas is important for preserving Bt technology and serving specific markets with greater added value to the grains. Therefore, research aimed at chemical weed control must also continue to be directed to conventional maize hybrids. The objective was to evaluate the selectivity of herbicides applied in preand post-emergence of a conventional maize hybrid cultivated in the Cerrado biome of Brazil. Two field experiments were set up, one in summer and the other in second season. The treatments were composed of eleven herbicide treatments, whose doses are presented in g ha-1 of active ingredient: S-metolachlor (1,440), S-metolachlor (1,680), mesotrione + atrazine (115.2 + 2,000), mesotrione + atrazine (192 + 2,000), tembotrione + atrazine (75.6 + 2,000), tembotrione + atrazine (100.8 + 2,000), nicosulfuron + atrazine (16 + 2,000), nicosulfuron + atrazine (24 + 2,000), [mesotrione + atrazine] ([120 + 1,200]), sequential application of [mesotrione + atrazine] ([60 + 600]), atrazine (2,000), plus a weeded control. Regardless of the experiment, all herbicides applied preand post-emergence of maize led to low percentages of phytointoxication. In both experiments, none of the treatments caused reductions in crop stand, confirming the absence of plant mortality due to the application of herbicides. Plant tipping/lodging was seen in summer maize, with no treatment effect. Maize 100grain mass and yield did not change as a result of the application of herbicides in preand post-emergence of the crop. All herbicide treatments evaluated showed selectivity for the conventional maize hybrid.
Resumo: O cultivo do milho convencional em áreas de refúgio é importante para preservação da tecnologia Bt e para atender mercados específicos com maior valor agregado aos grãos. Portanto, as pesquisas voltadas ao controle químico de plantas daninhas também devem continuar direcionadas aos híbridos convencionais de milho. O objetivo foi avaliar a seletividade de herbicidas aplicados em pré e pós-emergência de um híbrido convencional de milho cultivado no bioma Cerrado do Brasil. Foram instalados dois experimentos de campo, um na safra verão e outro segunda safra. Os tratamentos foram onze herbicidas, cujas doses são apresentadas em g ha-1 de ingrediente ativo: S-metolachlor (1.680), mesotrione + atrazine (115,2 + 2.000), mesotrione + atrazine (192 + 2.000), tembotrione + atrazine (75,6 + 2.000), tembotrione + atrazine (100,8 + 2.000), nicosulfuron + atrazine (16 + 2.000), nicosulfuron + atrazine (24 + 2.000), [mesotrione + atrazine] ([120 + 1.,200]), aplicação sequencial de [mesotrione + atrazine] ([60 + 600]), atrazine (2.000), mais testemunha capinada. Independentemente do experimento, todos os herbicidas aplicados pré e pós-emergência do milho proporcionaram baixos percentuais de fitointoxicação. Em ambos os experimentos nenhum dos tratamentos causou redução no estande, confirmando a ausência de mortalidade das plantas pela aplicação de herbicidas. O tombamento/acamamento das plantas foi observado no experimento realizado de verão e não observou efeito entre tratamentos. Massa de 100 grãos e produtividade do milho não alteraram em função da aplicação de herbicidas na pré e pósemergência da cultura. Todos os tratamentos herbicidas avaliados apresentaram seletividade ao híbrido de milho convencional. |

| Conteúdo: | Abstract: Marine fisheries and aquaculture are important contributors to global food security but disturb biogeochemical cycles from local to global scales. In this Review, we summarize how marine fisheries and aquaculture affect biogeochemical cycling of carbon, nitrogen and phosphorus, and discuss differences in the spatial scale, duration and magnitude of their biogeochemical consequences. Globally, marine capture fisheries and aquaculture remove approximately 21.0 Tg C year–1, 4.6 Tg N year–1 and 0.97 Tg P year–1 from the ocean, dominated by fish and shellfish removal. Point-of-harvest activities in marine capture fisheries result in biomass extraction, fishing gear impacts on the sea bed, fuel use and emissions, lost fishing gear and altered trophic structure. Aquaculture involves the addition and subsequent extraction of biomass, and habitat alteration during the introduction of farm structures. These disturbances affect the biogeochemistry of the water column and sediment, influencing the cycling and fate of nutrients over days to centuries and from local to global scales. For example, animals raised in aquaculture excrete 6.5 Tg N year–1 and 1.2 Tg P year–1, contributing to global-scale effects. Better incorporating these biogeochemical effects into environmental footprint assessments of products can guide more sustainable decision-making in the sector. |

| Conteúdo: | Abstract: Green economy is a model designed for economic growth in line with socio-environmental equity. Practices, processes, and products characterized by low carbon consumption and emissions, innovation and efficiency in the management of natural resources and waste, as well as social inclusion and governance, contribute to this transition. Bioinputs and bioenergy represent two pillars of a more environmentally and socially sustainable economy, being intrinsically linked to the reduction and optimization of the use of chemical fertilizers, pesticides, and non-renewable components in production systems. Both topics will be addressed in this article, with emphasis on the contributions of Brazilian Agricultural Research Corporation (Embrapa). The corporation’s research into bioinputs and bioenergy began in the 1970s, and had resulted in knowledge and technology transfer for the production sector, and the development of innovative products through partnerships with both public and private sectors. The diversification of raw materials and processes, with a focus on agronomic efficiency, energy security, economic resilience, and reduced environmental impact, is contemplated in Embrapa’s research for a better use of biomass. A proposal for future advances and an overview of the challenges yet to be overcome in these areas are also presented in this article. --- Resumo: A economia verde é um modelo concebido para o crescimento econômico em consonância com a equidade socioambiental. Práticas, processos e produtos caracterizados por baixos consumo e emissões de carbono, inovação e eficiência na gestão de recursos naturais e resíduos, bem como inclusão social e governança, contribuem para esta transição. Bioinsumos e bioenergia representam dois pilares de uma economia ambiental e socialmente mais sustentável, estando intrinsecamente ligados à redução e à otimização do uso de fertilizantes químicos, pesticidas e componentes não renováveis em sistemas de produção. Ambos os temas serão abordados no presente artigo, com ênfase às contribuições da Empresa Brasileira de Pesquisa Agropecuária (Embrapa). As pesquisas da empresa em bioinsumos e bioenergia iniciaram na década de 1970, tendo resultado na transferência de conhecimentos e tecnologias para o setor produtivo, e no desenvolvimento de produtos inovadores por meio de parcerias com os setores público e privado. A diversificação de matérias-primas e processos, com foco na eficiência agronômica, segurança energética, resiliência econômica e redução do impacto ambiental, é contemplada nas pesquisas da Embrapa, para um melhor aproveitamento da biomassa. Uma proposição de futuros avanços e uma visão dos desafios ainda a serem superados nestas áreas também são apresentadas neste artigo. |

| Conteúdo: | Abstract: Cyclamen (Cyclamen spp.) is a widely cultivated ornamental plant. Among the soil-borne pathogens affecting cyclamen, Fusarium wilt, caused by Fusarium oxysporum f. sp. cyclaminis, is one of the most significant phytosanitary challenges. This study aimed to evaluate the antifungal potential of graphene oxide and β-caryophyllene, separately and in combination, applied either by spraying or through endotherapy (bulb injection), to control Fusarium wilt in cyclamen. The combined application of these antifungal agents proved more effective, resulting in 40–60% mortality of infected plants, compared to 100% mortality in the untreated control group. A sorption study of fusaric acid on graphene oxide was also conducted to better understand its antifungal activity, along with an ecotoxicological assessment of β-caryophyllene to evaluate its environmental safety. Overall, the strong synergistic effect between graphene oxide and β-caryophyllene against Fusarium oxysporum f. sp. cyclaminis highlights their potential use in plant protection and supports the advancement of sustainable agricultural practices. |

| Conteúdo: | Resumo: Este estudo teve como objetivo caracterizar o perfil socioeconômico de famílias extratoras de castanha-da-amazônia (Bertholletia excelsa), quantificar a produção das últimas três safras e identificar as práticas de manejo utilizadas em comunidades locais na Floresta Nacional do Tapajós (FLONA) do Tapajós, em Belterra, Pará. Foram realizadas entrevistas estruturadas com 24 famílias das comunidades Boa Esperança, Branco e São Jorge. Os resultados revelaram que o perfil dos entrevistados é de baixa escolaridade, com a atividade extrativista sendo parte de uma estratégia de pluriatividade, complementada por programas de transferência de renda como o Bolsa Família. A produção média familiar variou significativamente entre as safras de 2013/2014 a 2015/2016, com uma queda acentuada na última safra, atribuída pelos extrativistas à redução das chuvas e às queimadas frequentes na região. As práticas de coleta, transporte e beneficiamento são rudimentares e realizadas majoritariamente sem a licença obrigatória do ICMBio, o que favorece a contaminação por aflatoxinas. A comercialização é dominada por atravessadores, que impõem baixos preços. Concluiu-se que a cadeia produtiva carece de organização, assistência técnica e políticas públicas que promovam boas práticas, valorizem o produto e garantam a legalidade da atividade, essenciais para a conservação do recurso e a melhoria da qualidade de vida nas comunidades. --- Abstract: This study aimed to characterize the socioeconomic profile of families harvesting Brazil nuts (Bertholletia excelsa), quantify production from the last three harvests, and identify management practices used in local communities in the Tapajós National Forest (FLONA) in Belterra, Pará. Structured interviews were conducted with 24 families from the Boa Esperança, Branco, and São Jorge communities. The results revealed that the interviewees have a low level of education, with extractive activity being part of a multi-activity strategy, complemented by income transfer programs such as Bolsa Família. Average family production varied significantly between the 2013/2014 and 2015/2016 harvests, with a sharp drop in the last harvest, attributed by extractivists to reduced rainfall and frequent fires in the region. Collection, transportation, and processing practices are rudimentary and mostly carried out without the mandatory ICMBio license, which favors aflatoxin contamination. Marketing is dominated by middlemen who impose low prices. The conclusion is that the production chain lacks organization, technical assistance, and public policies that promote good practices, value the product, and guarantee the legality of the activity, all of which are essential for conserving the resource and improving the quality of life in communities. |

| Conteúdo: | This study quantified carbon (C), nitrogen (N), and sulfur (S) concentrations in the litterfall of a native Brazil nut (Bertholletia excelsa) stand in the Tapajós National Forest, Belterra (Pará, Brazil), across dry and wet seasons. Monthly collections were conducted from August 2015 to July 2016 within a permanent plot of the MapCast Project, using 12 circular litter traps (0.25 m² each) systematically distributed in the forest. Litterfall was separated into leaves, flowers and fruits, wood, and miscellaneous fractions. After drying and sorting, samples were analyzed for C, N, and S contents using an elemental analyzer (CHNS/O). Seasonal patterns in elemental composition were observed: higher N and S concentrations occurred during the wet season, particularly in the miscellaneous fraction, whereas C was more abundant in the dry season, especially in leaves. Nevertheless, differences between seasons were not statistically significant (t-test, p ≤ 0.05). Significant correlations between nutrient contents and climatic variables (precipitation and temperature) were detected, emphasizing the responsiveness of litterfall to environmental variation. Overall, the results demonstrate that litterfall acts as a key reservoir and pathway for nutrient transfer in Brazil nut-dominated Amazonian forests, contributing to nutrient cycling and sustaining soil fertility. The persistence of litter on the soil surface plays an essential role in conserving edaphic fertility and supporting ecological stability. These findings provide valuable insights for forest management and conservation practices, while also advancing the understanding of biogeochemical processes that regulate the functioning and resilience of tropical ecosystems. |

| Conteúdo: | Abstract: Background: N-Nitrosodimethylamine (NDMA) is an organic xenobiotic compound and a well-established mutagen and carcinogen. Its potential to cause reproductive and developmental toxicity at low, relevant doses is unclear. This study evaluated the effects of combined maternal and paternal NDMA exposure, both preconceptionally and during gestation, on maternal health and embryotoxicity in rats. Methods: Rats were treated orally with vehicle (5 males, 10 females) or NDMA (7.2 ng/kg/day; 5 males, 12 females). Both sexes were exposed from postnatal day (PND) 60 to 90 (31 days); females continued during mating, and pregnant females from gestational day (GD) 0 to 20. On GD 20, dams were euthanized for hemato-biochemical and embryofetal evaluations. Results: Clinical toxicity, fertility indices, and embryofetal parameters did not differ between groups. In NDMA-exposed dams, hematological analyses showed a significant reduction in lymphocyte percentages, an increase in monocyte counts, and a decrease in basophils, accompanied by elevated serum urea levels and reduced alanine aminotransferase (ALT) activity. Placental analyses were comparable between groups. Female fetuses exhibited a reduction in appropriate for gestational age (AGA) classifications with a concomitant increase in large for gestational age (LGA), while in males a borderline increase in placental efficiency was detected. No significant external, visceral, or encephalic malformations were observed. However, skeletal analysis revealed a significantly increased incidence of supernumerary ribs in NDMA-exposed fetuses. Conclusion: Combined maternal and paternal exposure to low-dose NDMA produced measurable adverse effects on maternal health and specific aspects of fetal development, highlighting its potential risk even at environmentally relevant exposure levels. |

| Conteúdo: | Abstract: Drought stress threatens global food security, highlighting the need for resilient crops. Harnessing rhizosphere microorganisms can improve plant performance in harsh conditions. Here, we investigated the rhizosphere microbiomes of drought-tolerant (BAT477, SEA5) and susceptible (IAC Milênio, IAC-Carioca 80SH) common bean cultivars (Phaseolus vulgaris L.) under contrasting water regimes in mesocosm experiments to assess microbiome functional modulation under drought. Analysis of plant growth, physiological responses, nutrient dynamics, and rhizosphere microbial functional diversity revealed that drought-tolerant cultivars exhibited greater water management, minimal growth reductions, and enrichment of beneficial microbial functions, including genes linked to drought tolerance. Notably, drought stress triggered differential abundance in 1864 microbial genes, highlighting a robust functional shift. Specifically, drought-tolerant cultivars showed an enrichment of genes related to osmotic response, photosynthetic efficiency (82–87 % reduction in photosynthesis in susceptible cultivars), oxidative stress mitigation, and osmoprotectant production, whereas susceptible cultivars relied more on genes associated with DNA repair and antioxidant defense, indicating a reactive rather than proactive stress response. Additionally, the rhizosphere microbiomes of drought-tolerant cultivars were enriched in functions related to biofilm formation, dormancy survival, and oxidative stress resistance. These cultivars also maintained higher photosynthetic activity and transpiration rates with more stable stomatal conductance. Upon rehydration, they partially restored physiological functions (e.g., 48–57 % recovery in photosynthesis), further demonstrating microbiome-conferred resilience. These findings underscore the potential of plant-microbiome interactions in adapting to water stress, suggesting that microbiome selection could be a promising strategy for developing drought-resilient crops and advancing sustainable agricultural practices. |

| Conteúdo: | Abstract: Postharvest rots caused by Fusarium pallidoroseum and Alternaria alternata limit the commercialization of melons. Managing these diseases is crucial to ensure the quality of commercialized melons. The use of essential oils (EOs) and their constituents in the postharvest treatment of melons is a promising new to control those diseases. Therefore, this study aimed to evaluate the antifungal activity of different EOs on the mycelial growth of F. pallidoroseum and A. alternata, to determine the Minimum Inhibitory Concentration (MIC) and to analyze the chemical composition of the selected EOs by Gas Chromatography/Mass Spectrometry (GC–MS), as well as to evaluate the antifungal activity of their major constituents. According to the results, the EOs of cinnamon bark, oregano, rosemary pepper, and clove basil showed higher antifungal activity against the studied pathogens, with MIC ranging from 0.50 μL mL−1 to 2.00 μL mL−1. GC–MS analysis identified carvacrol, ρ-cymene, and thymol as the major constituents of oregano EO; in cinnamon bark EO, cinnamaldehyde, o-methoxy, and cinnamyl; in rosemary pepper EO, thymol, ρ-cymene, and caryophyllene; and in clove basil EO, eugenol, ρ-cymene, and caryophyllene. The mixture of the three major constituents of each EO was more efficient than the pure EOs, with lower MIC value, ranging from 0.50 μL mL−1 to 0.75 μL mL−1. Therefore, using a mixture of major constituents of EOs has been demonstrated to be an efficient postharvest treatment to control rots in melon. |

| Conteúdo: | Abstract: The objective of this work was to investigate three endophytic bacterial strains as to their ability to promote the growth and rooting of black pepper stem cuttings, as well as to determine the mechanisms involved in the promoting activity through molecular methods. The strains were identified by 16S sequencing as belonging to the genera Bacillus, Priestia, and Lysinibacillus. They were characterized for the production of indoleacetic acid (IAA), phosphate solubilization, and siderophore production. In two assays, the roots of the cuttings were immersed in bacterial suspensions to evaluate growth promotion through plant height, stem diameter, and root and shoot dry mass. The Bacillus sp. C1.4 and Priestia sp. T2.2 strains were able to produce siderophores, whereas Priestia sp. T2.2 and Lysinibacillus sp. C5.11 produced IAA. In addition, Priestia sp. T2.2 significantly increased plant height and dry mass, whereas Lysinibacillus sp. C5.11 significantly increased root dry mass. Therefore, Priestia sp. T2.2 and Lysinibacillus sp. C5.11 are able to promote the growth and rooting of black pepper stem cuttings, respectively. This growth promotion is linked directly to the production of IAA and siderophores. --- Resumo: O objetivo deste trabalho foi investigar três isolados de bactérias endofíticas quanto à sua capacidade de promover o crescimento e o enraizamento de estacas de pimenta-do-reino, bem como determinar os mecanismos envolvidos na atividade promotora por métodos moleculares. Os isolados foram identificados por sequenciamento 16S como pertencentes aos gêneros Bacillus, Priestia e Lysinibacillus. Foram caracterizados quanto à produção de ácido indolacético (IAA), à solubilização de fosfato e à produção de sideróforos. Em dois ensaios, as raízes das estacas foram imersas em suspensões bacterianas para avaliar a promoção do crescimento por meio de altura da planta, diâmetro do caule e massa seca de raízes e brotos. Os isolados Bacillus sp. C1.4 e Priestia sp. T2.2 foram capazes de produzir sideróforos, enquanto Priestia sp. T2.2 e Lysinibacillus sp. C5.11 produziram IAA. Além disso, o isolado Priestia sp. T2.2 aumentou significativamente a altura e a massa seca da planta, enquanto Lysinibacillus sp. C5.11 aumentou significativamente a massa seca da raiz. Portanto, Priestia sp. T2.2 e Lysinibacillus sp. C5.11 são capazes de promover o crescimento e o enraizamento de estacas de pimenta-do-reino, respectivamente. Esta promoção de crescimento está diretamente ligada à produção de IAA e sideróforos. |

| Conteúdo: | Abstract: Headwater streams play a crucial role in the formation of rivers; they boast numerous springs and serve as hotspots for aquatic biodiversity within watersheds. However, human activities frequently compromise the health of these environments. Common disturbances include the removal of riparian vegetation, sedimentation in the streambed, and the introduction of pollutants such as pesticides. This study sought to assess the macrobenthic community in three headwater rivers over a 9-month period, examining variations in water quality and community composition across different land uses. Key water quality variables - electrical conductivity and total suspended solids - were elevated at the Extrema (EX) Stream, likely attributable to pasture management practices. The Toledo (TO) Stream had higher water temperature and phosphate levels, potentially linked to the removal of riparian forest and the use of fertilizers in vegetable cultivation, respectively. Regarding the benthic community, metrics such as dominance (D); the percentage of Ephemeroptera, Plecoptera, and Trichoptera (% EPT); the EPT/Chironomidae ratio; and the Shannon-Wiener diversity index (H’) revealed a clear gradient in environmental health among the three study sites. The Monte Verde (MV) stream emerged as the most pristine one, followed by the EX and TO sites. These data underscore the deleterious impact of unsustainable agricultural practices. In conclusion, such agricultural activities exert a negative influence on both environmental quality and benthic macroinvertebrate communities in headwater streams.
Resumo: Os córregos e suas muitas nascentes são locais importantes para a formação dos rios e geralmente também são hotspots de biodiversidade aquática na bacia hidrográfica. As atividades humanas impactam a saúde desses ambientes, muitas vezes com a retirada da vegetação ciliar e também a entrada de sedimentos no leito do curso d’água, além da carga de poluentes como agrotóxicos. Este estudo teve como objetivo avaliar a comunidade macrobentônica em três riachos de cabeceira, ao longo de nove meses, monitorando a qualidade da água e a composição da comunidade com diferentes usos do solo. As concentrações das variáveis de qualidade da água, condutividade elétrica e sólidos suspensos totais, foram mais elevados no trecho fluvial em Extrema (EX), o que pode estar associado ao manejo da pastagem. No córrego em Toledo (TO), a temperatura da água e o fosfato foram mais elevados, provavelmente devido à retirada de mata ciliar e fertilizantes utilizados no cultivo de hortaliças, respectivamente. Quanto à comunidade bentônica, as métricas Dominância (D), % EPT, EPT/Chironomidae e o índice de diversidade de Shannon-Wiener (H’) mostraram claramente um gradiente de saúde ambiental existente nos riachos estudados, sendo o de Monte Verde (MV) o mais preservado, seguido pelos córregos de Extrema (EX) e Toledo (TO). Esses dados evidenciam o impacto deletério de práticas agrícolas insustentáveis. Concluímos que tais atividades agrícolas influenciaram negativamente a qualidade ambiental e a comunidade de macroinvertebrados bentônicos nesses córregos de cabeceira. |

| Conteúdo: | Abstract: For the large-scale use of Pochonia chlamydosporia as a bionematicide, cost-effective production coupled with robust stabilization processes is essential. Submerged liquid fermentation yields large amounts of infective blastospores in a short period. This study aimed to evaluate the nematicidal activity of P. chlamydosporia blastospores from two fungal strains against the eggs of two plant-pathogenic nematodes, as well as to assess the use of various additives to enhance their dehydration tolerance and storage stability. For the more promising strain, submerged culture yielded 1 × 109 blastospores mL-1 after 96 h. Juvenile hatch inhibition was more pronounced with blastospores (64.8%–86.7%) than conidia (48.2%–65.3%) on Meloidogyne javanica and M. enterolobii eggs, respectively. Skim milk added to the liquid medium prior to inoculation or 72 h after fermentation protected fungal cells from dehydration. Following dehydration, storage stability after 10 days was significantly greater at 4°C compared to 25°C. Stabilization processes to prevent cell mortality during dehydration are crucial for the development of blastospores as active ingredients in bionematicides. |

| Conteúdo: | Abstract: This work aimed to conduct a systematic literature review on the evaluation of agricultural research impact, seeking to answer the question: “What have been the predominant themes, methodologies, and trends of evaluation studies on the agricultural research impact over time?” In order to do so, a textual data analysis was applied using natural language processing (NLP) techniques, such as tokenization and topic modeling. The analysis of 239 studies from 1969 to 2022 identified some thematic groups (climate change and food security, technology adoption, challenges in developing countries, sustainable agricultural practices, and poverty reduction) and 73 methodologies (methodological approaches, methods, and techniques). An increasing thematic focus was also observed on sustainability, resource management, and social impacts. The use of multiple methodologies within the same study grew in the 2000s. Although quantitative approaches have been the most frequently used in those studies, the findings show an emerging balance between qualitative and quantitative approaches, as well as a growing adoption of mixed methods.
Resumo: Este trabalho teve como objetivo fazer uma revisão sistemática da literatura sobre a avaliação de impacto da pesquisa agrícola, buscando responder à pergunta: “Quais têm sido os temas, metodologias e tendências predominantes nos estudos de avaliação de impacto da pesquisa agrícola ao longo do tempo?” Para tanto, aplicou-se uma análise de dados textuais, por meio de técnicas de processamento de linguagem natural (PLN), como “tokenização” e modelagem de tópicos. A análise de 239 estudos de 1969 a 2022 identificou alguns grupos temáticos (mudanças climáticas e segurança alimentar, adoção de tecnologia, desafios em países em desenvolvimento, práticas agrícolas sustentáveis e redução da pobreza) e 73 metodologias (abordagens metodológicas, métodos e técnicas). Observou-se também um foco temático crescente em sustentabilidade, gestão de recursos e impactos sociais. O uso de múltiplas metodologias dentro do mesmo estudo cresceu nos anos 2000. Embora as abordagens quantitativas tenham sido as mais frequentemente utilizadas, a pesquisa mostra um equilíbrio emergente entre abordagens qualitativas e quantitativas, bem como uma adoção crescente de métodos mistos. |

| Conteúdo: | Abstract: The region of the São Francisco River Valley (VSF) in Brazil produces 90–95% of mangoes and grapes for export; therefore, they are subjected to international phytosanitary measures. Bactrocera carambolae Drew & Hancock, 1994 (Diptera: Tephritidae) is a present quarantine pest in Brazil, restricted to the states of Amapá, Roraima, and Pará. Surveys were conducted to identify parasitoids to be used against B. carambolae, in the event of its future detection in the region. A total of 1,292.80 kg of 14 different types of fruits were collected, resulting in the recovery of 27,367 puparia. From these puparia, 18,433 fruit flies (Tephritidae) emerged: 15,679 adults of Ceratitis capitata (Wiedemann, 1824) and 2,754 of Anastrepha spp. Additionally, 557 parasitoid specimens of seven species were recovered from Tephritidae family: Tetrastichus giffardianus Silvestri, 1915 (Hymenoptera: Eulophidae), Doryctobracon areolatus (Szépligeti, 1911) (Hymenoptera: Braconidae), Utetes anastrephae (Viereck, 1913) (Hymenoptera: Braconidae), Asobara anastrephae (Muesebeck, 1958) (Hymenoptera: Braconidae), Ganaspis pelleranoi (Brèthes, 1924) (Hymenoptera: Figitidae), Pachycrepoideus vindemmiae (Rondani, 1875) (Hymenoptera: Pteromalidae), and Spalangia simplex Perkins, 1910 (Hymenoptera: Spalangiidae). Besides the abovementioned species, Tropideucoila weldi Lima, 1940 (Hymenoptera: Figitidae) emerged from unidentified host family (Tephritidae or Lonchaeidae). The parasitoids A. anastrephae, G. pelleranoi, S. simplex, U. anastrephae, and T. weldi were recorded for the first time in the state of Pernambuco (PE, Brazil). The predominant species were D. areolatus (45.27%) and T. giffardianus (23.38%), and their potential use as bioagents to control B. carambolae, in case of detection in the VSF, were discussed. |

| Conteúdo: | Abstract: The herbicide tembotrione may be seletivity to sorghum, which is of utmost importance in grain production systems. Thus, the present study aimed to evaluate the selectivity of tembotrione + atrazine combinations applied post-emergence at different phenological stages of grain sorghum. Four experiments were carried out in Rio Verde and Montividiu (state of Goiás) in succession to soybean cultivation in 2017 and 2018. The experiments were carried out in randomized block design with six replications, both in a (3x2) + 1 factorial arrangement. The first factor referred to three vegetative stages of application (V3, V5 and V7) associated with two doses of tembotrione (90 and 180 g ha-1) combined with atrazine (1,000 g ha-1)and and an additional treatment with no herbicide application. Tembotrione + atrazine applications at the V7 stage caused less damage to grain yield and dry mass accumulation in relation to V3 and V5. The dose of 90 g ha-1 tembotrione + atrazine combined with atrazine resulted in higher grain yields compared to 180 g ha-1, although still at lower levels compared to the treatment with no herbicides. Thus, herbicide tembotrione at doses of 90 and 180 g ha-1 combined with atrazine did not have selectivity for grain sorghum in applications at V3, V5 and V7 stages. |

| Conteúdo: | Abstract: Enzymatic preparations in juice processing come in different formulations, but their enzymatic activities on the stability of this beverage must be studied. This study evaluated five commercial yield and color extraction preparations concerning the chemical composition of grape juice, color, and phytochemicals quantified in HPLC. The activity of the enzymes was evaluated, and a study of the stability of the juices over 360 days was carried out. The color extraction enzymes Everzym Thermo and Endozym Rouge (hemicellulases) increased the content of flavonoids, especially malvidin-3-glucoside. The Endozym Pectofruit PR preparation (pectin lyase) stood out for its yield and extraction of organic acids such as tartaric. When assessing the stability of the juice using the half-life parameter, it became clear that all the juices showed similar evolutionary behavior, with more accelerated degradation of the components related to color in the first 100 days. Even though the Everzym Thermo preparation showed greater color extraction, it had higher degradation rates for these parameters and anthocyanins than the other preparations evaluated. At the end of the storage period, the differences in color and anthocyanins were small between the preparations, practically equal to the control. This shows that in the juice obtained without enzymes, the nondegradation of polysaccharides may be associated with a protective effect on color and anthocyanins. |

| Conteúdo: | Abstract: Due to the rising demand for bioenergy, a certain amount of sugarcane straw is often removed for ethanol production, but this practice may compromise health soil. In addition to the amount of straw, growing concern with the environment has made the use of diazotrophic plant-growth promotion bacteria (DPGPB) an alternative to the use of nitrogen fertilizers. A research was designed with the aim of evaluating the effect of different amounts of straw kept on the soil on soil microbial and enzymatic parameters and on sugarcane yield during the first ratoon. The field experiment was carried out in randomized blocks, using nitrogen fertilizer (NF) or DPGPB (BI), both with four straw levels. The parameters evaluated were: β-glucosidase (GA), urease (UR) and acid phosphatase (APA) activities, fluorescein diacetate activity, basal soil respiration, microbial biomass N, total C, total N and labile carbon. Responses were not obtained for various parameters with respect to the straw levels which was attributed to the short experimental period. In general, the evaluated parameters were always higher in the BI treatment, except for APA, which was lower in this treatment. This fact could be attributed to the greater capacity of the inoculated plants to make phosphorus available to the plants, which could reduce APA. The absence of a response for sugarcane yield between the NF and BI treatments demonstrates the beneficial effect of the bacteria in the inoculant in suppressing plants with adequate nitrogen contents. Greater yields were obtained for the L64 and L100 straw levels with no significant difference. This demonstrates the adequateness of removing part of the straw to produce second generation ethanol. |

| Conteúdo: | Resumo: Peixes representam a proteína animal mais consumida no mundo, e neste sentido, o Brasil se destaca pela prática da tilapicultura. A contaminação de águas com pesticidas é conhecida e requer atenção quanto seu acúmulo em peixes, principalmente os componentes persistentes, tais como os organoclorados. Portanto, este trabalho apresenta a validação da metodologia QuEChERS (Rápido, Fácil, Barato, Efetivo, Robusto e Seguro) - citrato para extração de 23 pesticidas em tilápia com análise por cromatografia gasosa acoplada a espectrometria de massa com analisador triplo quadrupolo (GC-MS/MS). Os pesticidas foram selecionados com base no potencial de bioacumulação em organismos aquáticos e capacidade analítica do laboratório. As condições de análise no equipamento foram individualmente otimizadas para cada pesticida, a fim de alcançar a máxima sensibilidade ao monitorar duas transições em modo MRM (Multiple Reaction Monitoring), uma para quantificação e outra para confirmação. O método foi validado em amostras de tilápia fortificadas em 5, 10, 20 e 40 μg Kg-1, sendo cada nível realizado em quintuplicata (n=5) e em dias diferentes de validações para determinar a precisão inter-dias. Os limites de quantificação foram 5,0 e 10 μg Kg-1 conforme o pesticida e mostraram precisão de 93,9 a 115,8%, precisão intra-dia de 4,6 a 17,3% e precisão inter-dia de 8,2 a 20%. O efeito matriz foi observado com aumento de sinal sendo necessário o uso de curva na matriz. As curvas de calibração foram lineares usando Trifenil fosfato (TPP) como padrão interno e coeficiente de determinação r2=0,99. Sessenta e quatro amostras de músculo de peixe provenientes do Baixo Rio São Francisco foram analisadas e não foram encontrados resíduos dos agrotóxicos em quantidades acima do limite de detecção do método. |

| Conteúdo: | Abstract: Agroforestry Systems (AFS) integrate trees, agronomic crops and forage species, focusing on agricultural sustainability and productivity. However, the lack of specific mechanization for AFS limits their efficiency. This research aimed to assess the adequacy of existing agricultural machinery for biomass handling in AFS and thus contribute to solving the issue of lack of specific mechanization in AFS for family farming, in order to foster the expansion of AFS lands. This study assessed three types of machinery for handling Mombaça grass (Megathyrsus maximus Jacq): coastal brushcutter (CBC), tractormounted rotary brushcutter (RBC), and mini grain reaper machine (GRM) throughout three cutting cycles. The dimensional analysis and Likert scale methods were employed for assessment of cutting height, handling time, labor cost, fuel consumption, regrowth speed, dry matter weight, and raking time of cut grass. Obtained through dimensional analysis, Pi-terms Π1 and Π3 represent, respectively, the treatment’s quality of cut and financial cost. The binomial Π1 × Π3 represents the cost-benefit ratio. CBC was suitable for small areas, to guarantee better grass regrowth rate, and higher biomass production, while providing the best cost-benefit ratio for fuel. GRM was the most adequate for obtaining the lowest operational costs, the lowest time required for raking up cut grass, higher biomass production, providing the best financial estimate for fuel. RBC was indicated for faster work, handling at higher scales, and considerably reduced physical strain.
Resumo: Sistemas Agroflorestais (SAFs) integram árvores, culturas de interesse agronômico e forrageiras, visando sustentabilidade agrícola e produtividade. Contudo, a falta de mecanização específica para SAFs limita sua eficiência. Esta pesquisa objetivou avaliar a adequação das máquinas agrícolas no manejo da biomassa em SAFs e contribuir para a solução do problema da falta de mecanização específica para SAFs cultivados pela agricultura familiar. O estudo avaliou três tipos de máquinas para o manejo do capim Mombaça (Megathyrsus maximus Jacq): roçadora costal (CBC), roçadora rotativa montada ao trator (RBC) e mini colhedora de grãos (GRM) ao longo de três ciclos de corte. Os métodos da análise dimensional e escala Likert foram empregados para a avaliação da altura de corte, tempo de manejo, custo de mão de obra, consumo de combustível, velocidade de rebrota, peso de matéria seca e tempo de amontoa. Os Pi-termos Π1 e Π3 representam, respectivamente, a qualidade do corte e o custo financeiro. O binômio Π1 × Π3 representa a relação custo-benefício. A CBC foi adequada para pequenas áreas, garantindo melhor vigor de rebrote, maior produção de biomassa e expressou a melhor relação custo-benefício. A GRM foi indicada para obter os menores custos operacionais, o tempo mais rápido necessário para amontoar o capim cortado, a maior produção de biomassa e a melhor previsão financeira de custo com combustível. A RBC foi adequada para realizar o trabalho mais rapidamente, para manejo em escalas maiores e para reduzir consideravelmente o esforço físico. |

| Conteúdo: | Resumo: A cana-de-açúcar é essencial no Brasil, ocupando 8,3 milhões de hectares e produzindo 30 bilhões de litros de etanol na safra 2021/2022. A vinhaça, subproduto dessa indústria, contém nutrientes como potássio, nitrogênio e fósforo, podendo beneficiar a fertilidade do solo e a saúde das plantas, promovendo uma agricultura mais sustentável. Este estudo avaliou os efeitos da aplicação localizada de vinhaça no crescimento inicial da cana-de-açúcar em solo arenoso na Fazenda Santa Rita (SR), Pirassununga – SP. O experimento foi realizado em um canavial de 9 ha com 200 linhas de 300 metros, espaçadas a 1,5 m, com 4 tratamentos: vinhaça localizada (Vlocal), vinhaça em área total (Vtotal), água localizada (W) e testemunha (T), cada um com 5 repetições. A aplicação de vinhaça foi de 3 mm (30 m³/ha). Analisaram-se a condutividade elétrica do solo, o teor de potássio e o desenvolvimento inicial da cana, com medições antes e após 30 dias. A vinhaça localizada aumentou a salinidade e o teor de potássio na camada superficial do solo, reduzindo o crescimento inicial das plantas, enquanto a vinhaça total também teve efeitos negativos, mas menos severos. Recomenda-se cautela no uso da vinhaça e estudos adicionais em solos arenosos e regiões com alta pluviosidade.
Abstract: Sugarcane is essential in Brazil, covering 8.3 million hectares and producing 30 billion liters of ethanol in the 2021/2022 harvest. Vinasse, a byproduct of this industry, contains nutrients such aspotassium, nitrogen, and phosphorus, which can benefit soil fertility and plant health, promoting more sustainable agriculture. This study evaluated the effects of localized vinasse application on the initial growth of sugarcane in sandy soil at Fazenda Santa Rita (SR), 806Fertirrigação com vinhaça...Irriga, Botucatu, v. 28, n. 4, p. 805-820, outubro-dezembro, 2023Pirassununga,SP. The experiment was conducted in a 9-hectare sugarcane field with 200 rows of 300 metersspaced 1.5 metersapart, with 4 treatments: localized vinasse (Vlocal), total area vinasse (Vtotal), localized water (W), and control (T), each with 5 replications. The vinasse application was 3 mm (30 m³/ha). The soilelectrical conductivity, potassium content, and initial sugarcane development were analyzed, with measurements taken before and 30 days after application. Localized vinasse increased salinity and potassium in the surface layer, reducing initial plant growth, whereastotal vinasse also had negative effects, although they were less severe. Caution is recommended in the use ofvinasse, with further studies needed in sandy soils and high-rainfall areas. |

| Conteúdo: | Abstract: Producers of citrus crops use different types of insecticides, such as neonicotinoids, to combat pests and diseases of these cultures. Neonicotinoids are systemic insecticides and are translocated to the plant tissue, which may leave residues in pollen and cause adverse effects on bees. Pesticide contamination of pollen is also a food safety issue in human nutrition since the product is consumed as a food supplement. Therefore, the determination of these pesticides in pollen is important to help understand their effects on bees because pollen is their main nutrient source. In this work, we developed and validated a method using UHPLC–MS/MS to determine pesticide residues in orange pollen using micro-QuEChERS extraction, which uses low consumption of solvent, sample, and reagents. The analytical method demonstrated linearity over the range of 50 to 1000 μg kg−1, with a correlation coefficient of ≥0.990. Trueness and precision were assessed using spiked samples, analyzed in quintuplicate at concentrations of 50, 100, and 200 μg kg−1. Trueness values ranged between 81 and 115 %, while precision, expressed as relative standard deviation (RSD), was consistently below 20 %. The limit of quantification (LOQ) was established at 50 μg kg−1, with acceptable precision and accuracy observed at this level. Experimental treatment samples showed high concentrations of clothianidin, imidacloprid, and thiamethoxam, while in commercial samples, the analytes were below the LOQ or not detected. |

| Conteúdo: | Abstract: Insect pests are an integral part of the agro-ecosystems. Among them, the fall armyworm (Spodoptera frugiperda - S. frugiperda), one of the most destructive cereal pests in the world, represents a significant threat to global food production. Botanical insecticides offer an eco-friendly pest management strategy to combat this serious issue. Piper aduncum (P. aduncum) provides an available source of essential oil with significant plant protection effects, including biological activity against fall armyworm. However, challenges such as low solubility, instability under environmental conditions, and potential phytotoxicity have limited the P. aduncum essential oil (OPA) widespread use. Nanoencapsulation emerges as a promising strategy to enhance the efficiency of botanical insecticides. This study describes the process of obtaining zein-based nanocarriers loaded with the P. aduncum essential oil using the anti-solvent precipitation method and analyzes the phytotoxicity and biological activity of the nanoformulations against fall armyworms. The P. aduncum essential oil (OPA) was successfully encapsulated in zein nanoparticles with 96 % encapsulation efficiency and exhibited an average size of 220 ± 20 nm, polydispersity indices lower than 0.3, pH 4.3, and positive charge. Phytotoxic OPA effects were not observed in bean plants exposed to the nanoformulation even at the highest concentration applied and an elevated germination index was obtained for seeds exposed to the nanoformulation. Encapsulated essential oil provoked higher mortality rates of S. frugiperda than emulsified ones. Thus, nanoencapsulation can be an efficient strategy for developing botanical pesticides and enhancing insecticidal activity, reducing the phytotoxicity of essential oils like P. aduncum, and promoting sustainable agricultural practices. |

| Conteúdo: | Abstract: The pyrolysis process of residues has emerged as a sustainable method for managing organic waste, producing biochars that offer significant benefits for agriculture and the environment. These benefits depend on the properties of the raw biomass and the pyrolysis conditions, such as washing and drying. This study investigated biochar production through slow pyrolysis at 300 °C, using eight biomass types, four being plant residues (PBR)—sugarcane bagasse, filter cake, sawdust, and stranded algae—and four non-plant-based residues (NPBR)—poultry litter, sheep manure, layer chicken manure, and sewage sludge. The physicochemical properties assessed included yield, carbon (C) and nitrogen (N) content, electrical conductivity, pH, macro- and micronutrients, and potentially toxic metals. Pyrolysis generally increased pH and concentrated C, N, phosphorus (P), and other nutrients while reducing electrical conductivity, C/N ratio, potassium (K), and sulfur (S) contents. The increases in the pH of the biochars in relation to the respective biomasses were between 0.3 and 1.9, with the greatest differences observed for the NPBR biochars. Biochars from sugarcane bagasse and sawdust exhibited high C content (74.57–77.67%), highlighting their potential use for C sequestration. Filter cake biochar excelled in P (14.28 g kg⁻1) and micronutrients, while algae biochar showed elevated N, calcium (Ca), and boron (B) levels. NPBR biochars were rich in N (2.28–3.67%) and P (20.7–43.4 g kg⁻1), making them ideal fertilizers. Although sewage sludge biochar contained higher levels of potentially toxic metals, these remained within regulatory limits. This research highlights variations in the composition of biochars depending on the characteristics of the original biomass and the pyrolysis process, to contribute to the production of customized biochars for the purposes of their application in the soil. Biochars derived from exclusively plant biomasses showed important aspects related to the recovery of carbon from biomass and can be preferred as biochar used to sequester carbon in the soil. On the other hand, biochars obtained from residues with some animal contributions are more enriched in nutrients and should be directed to the management of soil fertility. |

| Conteúdo: | A demanda social por de uma pesquisa responsável, orientada para a resolução de problemas, e com um impacto real, somada à crise climática e de desigualdade global, está levando as organizações de pesquisa a repensar suas estratégias de impacto para além dos indicadores de desempenho acadêmico baseados em publicações científicas. Algumas dessas organizações realizam pesquisa aplicada e procuram avaliar os efeitos concretos das suas atividades. É o caso das instituições de pesquisa agrícola, cuja missão é melhorar o desempenho dos sistemas eco-agroalimentares em todas as dimensões da sustentabilidade. No entanto, essas avaliações muitas vezes permanecem focadas em linhas específicas de pesquisa e indicadores de desempenho clássicos, sem qualquer reflexão real sobre as teorias de mudança que permitiriam avaliar os impactos. Geralmente essas avaliações privilegiam as métricas quantitativas, concentrando-se em questões como \"quais são os benefícios de cada dólar investido?\" e os resultados tangíveis da pesquisa (publicações, patentes, tecnologias, eventos), em detrimento da compreensão da apropriação de resultados de pesquisa pelos stakeholders, das mudanças de comportamento associadas e dos mecanismos subjacentes. Esse viés é acentuado por mecanismos de financiamento que favorecem projetos de curto prazo, com estruturas lógicas focadas em resultados, em vez de mudanças comportamentais e impactos como tal. Portanto, é necessária uma visão mais ampla para compreender a pesquisa sob a perspectiva do seu impacto, tanto no nível das organizações, quanto do ecossistema de pesquisa como um todo. --- Public demands for accountable, problem-solving, and impactful research, together with global climate and inequality crises, push research organisations to rethink their impact strategies beyond academic performance indicators based on peer-reviewed publications. Part of these organisations conduct applied research and attempt to assess the effect of their activities on the ground. This is the case for agricultural research organisations, which mission is to improve performances of eco-agri-food systems across all sustainability dimensions. Yet, these assessments have mainly remained concentrated along specific research lines and performance indicators, lacking explicit reflection on the theories of change against which the impact of research should be evaluated. They also tend to prioritize quantitative measures, with the traditional question “which benefits from one invested dollar?” and focus on research outputs (such as publications, patents, technologies, events), less often on understanding the uptake of these outputs by stakeholders, the associated behavioral changes they generate, and the mechanisms underlying those changes. This is encouraged by research-funding mechanisms that tend to favor short-term projects, logic-framework exercices, and projects’ output rather than behavioral change and impact per se. More in-depth considerations are necessary to examine research through the prism of impact, at both research organisation and wider research ecosystem levels. --- Les demandes sociétales en faveur d’une recherche à la fois responsable, orientée vers la résolution de problèmes et ayant un réel impact, couplées aux crises globales du climat et des inégalités, poussent les organisations de recherche à repenser leurs stratégies d’impact au-delà des indicateurs de performance académiques basés sur les publications scientifiques. Certaines de ces organisations mènent des recherches appliquées et tentent d’évaluer les effets concrets de leurs activités. C’est le cas des institutions de recherche agricole, dont la mission est d’améliorer les performances des systèmes éco-agro-alimentaires dans toutes les dimensions de la durabilité. Pourtant, ces évaluations restent souvent centrées sur des lignes de recherche spécifiques et des indicateurs de performance classiques, sans réelle réflexion sur les théories du changement permettant d’évaluer les impacts. Ces évaluations privilégient généralement les mesures quantitatives, se concentrant sur des questions comme « quels bénéfices pour un dollar investi ? » et les résultats tangibles de la recherche (publications, brevets, technologies, événements), au détriment de la compréhension de l’appropriation de ces résultats par les acteurs, des changements de comportements associés, et des mécanismes sous-jacents. Ce biais est accentué par des mécanismes de financement qui favorisent des projets à court terme, avec des cadres logiques portés sur les résultats, plutôt que sur les changements comportementaux et l’impact en tant que tel. Une vision plus large est donc nécessaire pour appréhender la recherche sous l’angle de son impact, au niveau des organisations et de l’écosystème de recherche dans son ensemble. |

| Conteúdo: | Resumo: Tem sido comum a presença de plantas voluntárias de soja em lavouras de crotalária (Crotalaria spectabilis) cultivada em segunda safra, necessitando assim a adoção de estratégias para o seu manejo. Este trabalho teve como objetivo avaliar a eficácia e a seletividade dos herbicidas pyrithiobac-sodium e ethoxysulfuron aplicados isoladamente em pós-emergência da crotalária visando ao controle de soja voluntária. Para tanto, foram instalados dois experimentos a campo, um avaliando a viabilidade de uso do herbicida pyrithiobac-sodium e outro do ethoxysulfuron. Em ambos os experimentos foi utilizado o delineamento de blocos casualizados, estando os tratamentos dispostos em esquema fatorial 2x4+2, com quatro repetições. No primeiro fator alocou-se à aplicação em pós-emergência dos herbicidas em dois estádios fenológicos distintos V3 e 3 folhas verdadeiras e V7 e 6 folhas verdadeiras, respectivamente para a soja e a crotalária. No segundo fator foi disposto doses crescentes dos herbicidas, sendo utilizadas as doses 14,0; 22,4; 30,8; e 39,2 g ha-1 para pyrithiobac-sodium e 18,0; 30,0; 42,0; e 54,0 g ha-1 para ethoxysulfuron. Os tratamentos adicionais corresponderam a uma testemunha infestada e outra capinada. Foram realizadas avaliações de controle visual da soja voluntária, bem como da fitointoxicação, estande, altura e massa seca de parte aérea das plantas de crotalária. De acordo com os resultados obtidos, o pyrithiobac-sodium na dose de 30,8 g ha-1, pode ser recomendado para aplicações quando as plantas de soja voluntária estiverem em V3 e as plantas de crotalária com 3 folhas verdadeiras, bem como o herbicida ethoxysulfuron na dose 18 g ha-1, pode ser recomendado para aplicações quando as plantas de soja voluntária estiverem em V3 ou V7 e as plantas de crotalária com três folhas verdadeiras. Esses dois herbicidas nas respectivas doses apresentam potencial para serem registrados para uso em áreas de cultivo de crotalária em sucessão à cultura da soja.
Abstract: The presence of volunteer soybean plants in showy crotalaria (Crotalaria spectabilis) crops grown in the second crop has been common, thus necessitating the adoption of strategies for their management. The objective of this work was to evaluate the effectiveness and selectivity of the herbicides pyrithiobac-sodium and ethoxysulfuron applied isolated in post-emergence of showy crotalaria in order to control volunteer soybean. For this purpose, two field experiments were set up, one evaluating the feasibility of using the herbicide pyrithiobac-sodium and the other using ethoxysulfuron. In both experiments, a randomized completely block design was used, with treatments arranged in a 2x4+2 factorial scheme, with four replications. The first factor was allocated to the post-emergence application of herbicides at two distinct phenological stages V3 and 3 true leaves and V7 and 6 true leaves, respectively for soybean and showy crotalaria. In the second factor, increasing doses of herbicides were arranged, using doses 14.0; 22.4; 30.8; and 39.2 g ha-1 for pyrithiobac-sodium, and 18.0; 30.0; 42.0; and 54.0 g ha-1 for ethoxysulfuron. The additional treatments corresponded to an infested check and a weeded check. Visual control evaluations of volunteer soybean were carried out, as well as phytointoxication, stand, height and dry mass of shoots of showy crotalaria plants. According to the results obtained, pyrithiobac-sodium at a dose of 30.8 g ha-1, can be recommended for applications when volunteer soybean plants are in V3 and showy crotalaria plants with 3 true leaves, as well as the herbicide ethoxysulfuron in dose 18 g ha-1, can be recommended for applications when volunteer soybean plants are at V3 or V7 and showy crotalaria plants owns three true leaves. These two herbicides at the respective doses have the potential to be registered for use in areas where showy crotalaria is grown in succession to soybean crop. |

| Conteúdo: | Abstract: The present study was carried out to evaluate: the effects of additives and their mixtures, used in pesticide formulations, on the conidial germination of Clonostachys rosea, and the efficacy of Clonostachys strains A10 and A11, alone or in mixture of additives, in inhibiting Botrytis cinerea conidial sporulation on Eucalyptus globulus leaf discs at different temperatures. Conidial germination of Clonostachys strains in potassium and calcium carbonate (0.5, 1, 2 g L-1), cornstarch and sodium alginate (10, 15, 20 g L-1) was similar to that of the control with water (93.7% − 97.3%); for titanium dioxide (2, 4, 6 g L-1) and carboxymethylcellulose (0.5, 1, 2 g L-1), the inhibition was between 7% and 16%. Glycerol completely inhibited conidial germination. The viability of Clonostachys conidia was maintained in mixtures containing additives (potassium and calcium carbonate, titanium dioxide and carboxymethylcellulose). Clonostachys strains in the mixtures of additives suppressed Botrytis sporulation on eucalyptus leaf discs between 15°C and 25°C. At temperatures from 15°C to 25°C, Clonostachys suppressed Botrytis sporulation on leaf discs when compared to control but, at 10°C, the pathogen sporulation inhibition was significantly lower when compared to that from 15°C to 25°C. The obtained results suggest that: 1- potassium and calcium carbonate, cornstarch, sodium alginate, titanium dioxide, and carboxymethylcellulose can be used in formulations containing Clonostachys spores; 2- Clonostachys can be used between 15°C and 25°C but, below this range, other strategies should be adopted.
Resumo: Neste estudo foram avaliados: os efeitos de aditivos, bem como de suas misturas, usadas em formulações de pesticidas, sobre a germinação de conídios de Clonostachys rosea; e a eficiência de C. rosea isolados A10 e A11, com e sem mistura dos aditivos, na inibição da esporulação de conídios Botrytis cinerea em discos de folhas de Eucalyptus globulus em diferentes temperaturas. A germinação de conídios dos isolados de Clonostachys em carbonato de potássio e de cálcio (0,5, 1, 2 g L-1) e amido de milho e alginato de sódio (10, 15, 20 g L-1) foi similar ao controle com água (93,7% - 97,3%); e para o dióxido de titânio (2, 4, 6 g L-1) e carboximetilcelulose (0,5, 1, 2 g L-1) a inibição foi entre 7 e 16%. Glicerol inibiu completamente a germinação de conídios. A viabilidade dos conídios de Clonostachys foi mantida nas misturas contendo aditivos (carbonato de potássio e de cálcio, dióxido de titânio e carboximetilcelulose). Os isolados de Clonostachys nas misturas dos aditivos suprimiram a esporulação de Botrytis nos discos de folhas de eucaliptos entre 15 °C e 25 °C. Nas temperaturas entre 15 °C a 25 °C, Clonostachys suprimiu a esporulação de Botrytis nos discos de folhas quando comparado com o controle, mas a 10 °C a inibição da esporulação do patógeno foi significativamente menor do que quando comparado com as temperaturas entre 15 °C a 25 °C. Esses resultados sugerem que: 1-carbonato de potássio e de cálcio, amido de milho, alginato de sódio, dióxido de titânio e carboximetilcelulose podem ser utilizados em formulações contendo esporos de Clonostachys; 2-Clonostachys pode ser utilizado entre 15°C e 25°C, mas abaixo desta faixa outras estratégias devem ser usadas. |

| Conteúdo: | Abstract: Brazil’s National Biofuel Policy (RenovaBio) promotes negative emission technologies (NETs) as one of the instruments to reduce the carbon intensity (CI) of biofuels; however, no mill in the country has integrated such strategies into its production processes to date. The present study examined the potential impact of two promising NETs (i.e, bioenergy with carbon capture and storage (BECCS) and field application of biochar) on the CI of sugarcane ethanol, calculated using the methodological approach adopted by RenovaBio. In addition, the assessment used data from the agricultural and industrial stages provided by 62 certified sugarcane mills. Results show that these strategies have the potential to significantly reduce the CI of ethanol. The obtained value of +32.8 g CO2e/MJ of hydrated ethanol (without NETs considered) could be reduced to +15.9 (with the application of 1.0 t biochar/ha), +10.4 (with BECCS from fermentation), and −81.3 (with BECCS from combustion). Ethanol-blended gasoline (produced in association with NETs) has the potential to reduce impacts; however, achieving reductions similar to those of electric and all-ethanol vehicles, when compared to conventional gasoline, would depend on NETs that are unlikely to be implemented (e.g. BECCS from combustion). Estimates show that the carbon credits made available in RenovaBio will probably not be sufficient to provide attractive financial viability. Other instruments, such as private funding through the voluntary carbon market (VCM) and specific national incentive policies, may be essential for financing NETs. |

Additionally, we proposed an innovative approach to develop a rice flour-based formulation of the biocontrol agent T. asperelloides CMAA 1584, designed to simulate a micro-bioreactor within the full biorefinery context. This approach enables in situ conidiation, extended shelf-life, and effective control of S. sclerotiorum. Our findings revealed that T. asperelloides CMAA 1584 was more effective in parasitizing S. sclerotiorum, while T. lentiforme CMAA 1585 demonstrated a more pronounced effect on cotton growth. Furthermore, an environmentally friendly bioprocess using rice flour as the main feedstock was successfully implemented to develop waste-free granular formulations of Trichoderma conidia. Such formulations successfully suppressed Sclerotinia and improved the shelf-life of the biofungicide. |

In the present study, the effect of a Subsurface Plastic Film Insertion System (SPFIS) on soil water retention was evaluated. Four plots were established using the plastic film, applied through subsoiling at a depth of 40 cm. Tensiometers were installed at soil depths of 0-10 cm, 10-20 cm, 20-30 cm, and 30-40 cm, and tension was recorded weekly. The results indicated lower soil water matric potential values in the plots with the plastic film compared to the control plots (without the film). These result can be attributed to the increased water retention and concentration around the films, which also resulted in a longer duration of elevated soil moisture content, even during periods of no rainfall. The SPFIS contributed to increased soil moisture, with the potential to enhance agricultural productivity.

| Conteúdo: | Abstract: To meet the growing demand for sustainable aquaculture, the biofloc technology (BFT) system has emerged as a promising solution, offering high productivity, improved water use efficiency, and enhanced environmental and biosecurity performance. Economic and risk analyses are essential tools for identifying the key technical and economic factors that determine the profitability and long-term sustainability of aquaculture systems. This study aimed to evaluate the economic feasibility and the risk associated with Nile tilapia juvenile production in a BFT system. Economic viability indicators were calculated using real data on capital investment, operational costs, and zootechnical performance from a production cycle. Scenario analyses were conducted to assess the effects of fluctuations in input prices and survival rates on overall economic outcomes. Stochastic simulations were also conducted to determine the probabilities of economic results. The items with the greatest impact on costs were the acquisition of the greenhouse and fingerlings, representing 27.64% of the initial investment and 33.24% of the operating cost, respectively. The BFT system showed a positive net margin and profitability per production cycle, with the exception of the pessimistic scenario. The risk analysis demonstrated that in 87.29% of the simulations resulted in a positive profit. Thus, the production of tilapia juveniles in a BFT system is an economically viable investment. However, its success is contingent upon specific technical and market conditions, underscoring the need for careful management and context-specific planning. |

| Conteúdo: | Abstract: Despite being a N-fixing legume, common bean (Phaseolus vulgaris) cultivation using diazotrophic bacteria is not commonly adopted by Brazilian farmers, who instead rely on mineral nitrogen sources like urea, increasing environmental and economic costs. Diversified systems that enhance soil quality may improve the crop’s ability to depend solely on biological nitrogen fixation. This study investigated how co-inoculation with Rhizobium spp. and Azospirillum brasilense (+I or -I), with or without mineral N (+N or -N), affects N2O–N fluxes, yield, and rhizospheric community of common bean. A trial was established within a 20-year-old integrated crop-livestock system (ICLS) over the 2019/2020 (Y1) and 2021/2022 (Y2) crop years. Soil and plant variables were assessed throughout both years. N2O–N fluxes were measured using manual static chambers targeting days following co-inoculation and N fertilization applications, while the 16S rRNA microbiome composition was assessed by metabarcoding samples collected during flowering. Yields (∼3000 kg ha−1) were relatively high and similar among treatments. Co-inoculation alone (+I-N) led to reduced N2O–N fluxes (yearly average of 43.8 ± 16.0 µg/m²/h). Co-inoculation reduced the N2O emission intensity of common bean; however, its effectiveness was limited when applied in conjunction with urea. Regardless of year and co-inoculation, N2O–N fluxes remained high when N fertilizer was used (averaging 108.3 ± 30.3 µg/m²/h). Microbial diversity was generally lower under N fertilization, with shifts in the abundance of nitrogen-related functional groups, particularly in the second year. Despite seasonal variations, results indicate that co-inoculation can mitigate N₂O emission while maintaining crop yield and soil organic matter (∼4 %) in this biodiverse ICLS system. |

| Conteúdo: | Abstract: Purpose of Review: Fungi have been explored as a potential source of alternative protein for human diets, contributing to mitigate concerns about the environmental impact and nutritional adequacy of current food systems. This review covers the use of fungal cell factories to produce recombinant proteins and mycoproteins, their nutritional benefits, and the challenges to achieve the increasing global demand for protein. Recent Findings: The continued advancements in scale-up strategies and genetic engineering, particularly CRISPR-Cas9 technology, have enhanced the application of filamentous fungi and yeasts for the production of recombinant proteins and high-quality mycoproteins. Mycoprotein is emerging as a promising food ingredient, offering a texture similar to meat, a favorable nutritional profile, and the capacity to scale up production. Several companies are developing innovative mycoprotein-based products, including meat and dairy substitutes, with a focus on enhancing their properties and improving consumer acceptance. Summary: While the goal is not to completely replace animal meat, fungal proteins represent a viable strategy to diversify protein sources, reduce the environmental footprint of food production, and enhance food security. Continued research and development in strain engineering, bioprocess optimization, and downstream processing are crucial to achieve the full potential of fungal cell factories. Addressing challenges related to consumer acceptance, technological properties, nutritional quality, and safety will be essential for the successful integration of mycoproteins into the future food market. |

| Conteúdo: | No transcorrer deste artigo, diversos termos relacionados ao controle bioló gico de doenças de plantas serã o utilizados, portanto é importante que sejam, desde já, conceituados. Controle biológico será utilizado como “o controle de um organismo por outro organismo” ou como “o controle de um agente causal de uma doença de planta por um microrganismo antagonista” ou, ainda, como “o uso de um organismo para reduzir a densidade populacional de outro organismo”. Entretanto, o conceito de controle biológico de doenças de plantas mais aceito pela comunidade científica é: “[...] a reduçã o da soma de inóculo ou das atividades determinantes da doença provocada por um patógeno, realizada por um ou mais organismos que não o homem” (Cook; Baker, 1983). Para estes autores, as atividades determinantes das doenças implicam crescimento, infectividade, virulência, agressividade e outras qualidades do patógeno ou processos que determinam a infecção, o desenvolvimento de sintomas e a reprodução. E os organismos incluem: indivíduos ou populações avirulentas, hipovirulentas dentro das espécies patogênicas; plantas hospedeiras manipuladas geneticamente ou por práticas culturais; microrganismos, para maior ou mais efetiva resistência contra o patógeno e antagonistas dos patógenos (microrganismos que interferem na sobrevivência ou atividades determinantes de doenças causadas por patógenos). Assim sendo, de acordo com Cook e Baker (1983), neste conceito, o controle biológico pode ser acompanhado de: práticas culturais para criar um ambiente favorável aos antagonistas e à resistência da planta hospedeira, ou ambas as coisas; melhoramento das plantas para aumentar a resistência ao patógeno ou para melhor se adaptar às atividades dos antagonistas; introdução dos antagonistas isolados não patogênicos e de outros organismos ou agentes benéficos; entre outras práticas culturais. Contudo, não somente no mercado brasileiro, como no mundial, considera-se basicamente como controle biológico o uso de um antagonista para controlar um fitopatógeno, sendo este conceito extremamente reducionista. |

| Conteúdo: | Microrganismos benéficos, como certas bactérias e fungos, desempenham papéis fundamentais em diversos ecossistemas; eles contribuem, por exemplo, no controle biológico de pragas e na promoção de crescimento de plantas, na descontaminação química de solos e até mesmo na qualidade da saúde humana, ao promover a digestão e prevenir infecções nocivas. No entanto, aproveitar todo o potencial da diversidade microbiana existente requer, muitas vezes, uma manipulação precisa de seu material genético, objetivando aprimorar características desejáveis ou introduzir novas funcionalidades. Nessa direção, surgiu, há pouco mais de dez anos, uma ferramenta inovadora, que promete um salto revolucionário nas capacidades de edição genética de diferentes organismos, denominada CRISPR/Cas9 (Doudna; Charpentier, 2014). O seu impacto na agricultura, mais especificamente no melhoramento genético de microrganismos benéficos, apresenta um potencial ainda difícil de ser mensurado. |

| Conteúdo: | Abstract: Plants have developed specific mechanisms to tackle environmental challenges. During one annual period, a dioecious yerba mate with rhythmic growth can present two growth units (GU1 and GU2) intercalated with two rest periods (R1 and R2). We hypothesized that photosynthetic performance will be much higher under monoculture (MO, high light) than under an agroforestry system (AFS, low light) over annual growth and that secondary sexual dimorphism (SSD) will be more expressed during rest than during growth periods. We evaluated the maximum net photosynthesis (Amax), apparent quantum efficiency of CO2 assimilation (Ф), respiration rate in the dark (Rd) and in the light (RL), RL/Rd ratio, maximum apparent rate of electron transport (Jmax), maximum apparent RuBisCO carboxylation rate (Vcmax), Jmax/Vcmax ratio, and chlorophyll indexes in four (two male and two female) clones. Light was reduced by 92%–95% in AFS compared to MO. Photosynthetic traits generally varied over the annual rhythmic growth and revealed higher photosynthetic performance under MO than AFS. Lower Amax and Rd in all clones under AFS than MO occurred together with higher inhibition of respiration by light (low RL/Rd) under AFS than MO. Despite the strong effect of cultivation systems and growth rhythmicity on photosynthetic traits, our data did not suggest that the frequency of SSD in photosynthetic performance (with the exception of the Jmax/Vcmax ratio) was related to the cultivation system or period of rhythmic growth. The SSD was expressed in a higher Chl b index and lower Chl a/b ratio in female than male plants during R2 and GU2, indicating lower sensitivity of females to extreme light conditions of two cultivation systems than males. Higher Amax and similar respiration rates (Rd and RL) in females compared to in males in early vegetative phases after pruning (herein R1 and GU1) could be considered as a fitness strategy of female plants in their additional effort to produce fruits and seeds in latter phases. Our results additionally revealed the importance of the evaluation period when assessing photosynthesis in plant species with rhythmic growth. |

| Conteúdo: | Abstract: The generation of electricity from sugarcane bagasse plays an important role in Brazil’s energy mix, particularly in complementing hydropower during the dry season and in mitigating the impacts of climate change. However, sugarcane is facing increasing challenges due to the occurrence of droughts. This study assesses drought risk of sugarcane, with a particular focus on its role in bagasse-based electricity generation. The IPCC AR5 Risk Assessment Framework was employed to evaluate two global climate change models, two representative concentration pathways (RCPs), and three land use scenarios. The present study employs a dynamic approach to analyse the interconnectivity of risk components, thereby contributing to the development of a methodology to compare risk scenarios considering changes in the system. Spatial analyses of hazard, exposure, and vulnerability were conducted, revealing dynamic risk across nine scenarios. This highlights the necessity of understanding the interconnectivity for a comprehensive risk analysis and the implementation of effective measures to mitigate risk. The findings emphasise the necessity of tailored risk management strategies to effectively address drought risks, focusing on the planning of sugarcane expansion and, more specifically, on the reduction of vulnerability. The results indicate that the reduction of vulnerability is dependent on the implementation of early warning systems, which serve as a crucial mechanism for the timely dissemination of drought information. Furthermore, access to water reservoirs (e.g. dams) and the implementation of efficient irrigation systems play a pivotal role in enhancing resilience and reduce further vulnerability within the sector. The analysis facilitates the identification of the strengths and the weaknesses of the systems for the implementation of targeted mitigation measures. These measures are intended to strengthen the sector’s resilience and sustainability, aligning with national objectives. |

| Conteúdo: | Abstract: Global climate change has driven breeding programs to develop abiotic stress‐resilient plant varieties. Traditionally, assessing drought resilience involves labor‐intensive and time‐consuming processes. This study used an unmanned aerial system (UAS) to predict key phenotyping traits in maize (Zea mays L.) and monitor plant response to drought during the crop cycle. We grew transgenic maize hybrids in two trials, one irrigated and another subjected to drought stress, and used a drone equipped with red–green–blue (RGB) and multispectral sensors to capture images of the plots over time. Machine learning models and various prediction scenarios revealed significant correlations between vegetation indices over time. Interestingly, the RGB sensor outperformed the multispectral sensor in trait prediction. Prediction accuracy across scenarios with untested genotypes and environments ranged from 0.40 to 0.70 for grain yield, 0.43 to 0.69 for days to anthesis, 0.51 to 0.67 for days to silking, and 0.35 to 0.57 for plant height. Ridge and random forest models consistently delivered the most accurate predictions across traits and environments. The vegetation indices normalized green–red difference index, VARI, and RCC also effectively predicted and captured the plant response to drought. This study highlights the value of UAS phenotyping as a practical tool for assessing abiotic stress due to its straightforward implementation. |

| Conteúdo: | Abstract: Trichlorfon (TCF) is an organophosphate parasiticide commonly used in aquaculture to treat ectoparasites. However, studies across various fish species have reported adverse effects even at sublethal doses. This study assessed the hematological and biochemical responses of Nile tilapia juveniles (Oreochromis niloticus) following a one-hour exposure to a 0.5 mg L⁻¹ bath of a commercial TCF-based product. It also evaluated the fish’s physiological recovery 28 hours after exposure. Results showed elevated plasma cortisol levels and a downregulation of glutathione-S-transferase (GST) activity in liver tissue among TCF-exposed fish compared to controls. Alterations in the leukogram of treated fish indicate an increased vulnerability to disease. These findings suggest that a 28-hour recovery period is insufficient to restore the physiological health of Nile tilapia juveniles after TCF exposure. The study highlights the importance of adopting best management practices (BMPs) when applying TCF treatments in aquaculture and underscores the need for further research on the short- and long-term physiological impacts of chemical treatments on fish.
Resumo: O triclorfon (TCF) é um parasiticida organofosforado comumente usado na aquicultura para tratar ectoparasitas. No entanto, estudos em várias espécies de peixes relataram efeitos adversos mesmo em doses subletais. Este estudo avaliou as respostas hematológicas e bioquímicas de juvenis de tilápia do Nilo (Oreochromis niloticus) após uma hora de exposição a um banho de 0,5 mg L-¹ de um produto comercial à base de TCF. O estudo também avaliou a recuperação fisiológica dos peixes 28 horas após a exposição. Os resultados mostraram níveis elevados de cortisol no plasma e uma regulação negativa da atividade da glutationa-S-transferase (GST) no tecido hepático entre os peixes expostos ao TCF em comparação com os controles. As alterações no leucograma dos peixes tratados indicam uma maior vulnerabilidade à doença. Essas descobertas sugerem que um período de recuperação de 28 horas é insuficiente para restaurar a saúde fisiológica dos juvenis de tilápia do Nilo após a exposição ao TCF. O estudo destaca a importância de adotar as melhores práticas de gerenciamento (BMPs) ao aplicar tratamentos com TCF na aquicultura e ressalta a necessidade de mais pesquisas sobre os impactos fisiológicos de curto e longo prazo dos tratamentos químicos em peixes. |
