| Conteúdo: | Abstract: Sustainable agriculture Biological control Plant protection Microbial revolution Synthetic microbiomes Bioinputs Beneficial microbes play crucial role in modern agriculture, serving as biopesticides, biostimulants/biofertilizers, and alleviating abiotic stress in crops. Their multifaceted functions contribute significantly to crop health and sustainability, aligning with the principles of regenerative agriculture by minimizing carbon footprints and reducing dependence on agrichemical inputs. The concept of ‘microbial consortia’, involving the combination of multiple fungal and bacterial species or strains, has gained recognition for its potential advantages over single species/strains applications. This method aims to employ a spectrum of ecological functions, encouraging biological equilibrium within agricultural systems. Recent research highlights how microbial consortia can directly and indirectly enhance plant health, through various mechanisms and interactions with their host plants. This review presents examples demonstrating the efficacy of microbial consortia as biopesticides and biostimulants/ biofertilizers. These consortia exhibit potential in managing plant diseases and pests, while also promoting plant growth and mitigating specific abiotic and biotic stresses in crops. This review examines real-world examples considering instances of success and failure, discusses methodologies employed for evaluating interactions, and also addresses challenges in the selection, production, and application of optimal microbial consortia for agricultural use providing valuable insights in the current and future prospects of microbial consortia in modern agriculture. |

| Conteúdo: | Abstract: Alum sludge (AS) is a by-product generated from drinking water treatment and produced in large amounts around the world. Its chemical composition makes this waste an emerging alternative source of silicon and aluminum for aluminosilicates or zeolite material production, which can add value to residues and contribute to the circular economy process on a global scale. In this sense, and considering the scarcity of information about AS, this review shows data collection about AS in different countries, including generation, chemical composition, and disposal information. The reuse of AS is discussed based on circular economy and the environmental gains derived from such approaches are highlighted, including the possibility of utilization with other residues (e.g., ash, bioproducts, etc). Moreover, this review shows and discusses the benefits and challenges of AS reuse in the synthesis process and how it can be a sustainable raw material for aluminosilicates and zeolite synthesis. The most common conditions (conventional or non-conventional) in zeolite synthesis from AS are mentioned and advantages, limitations and trends are discussed. The discussions and data presented can improve the AS management and reuse legislations, which certainly will collaborate with sustainable AS use and circular economy processes. |

| Conteúdo: | Abstract: Background: Bacillus subtilis is well known for promoting plant growth and reducing abiotic and biotic stresses. Mutant gene-defective models can be created to understand important traits associated with rhizosphere fitness. This study aimed to analyze the role of exopolymeric genes in modulating tomato rhizosphere microbiome assembly under a gradient of soil microbiome diversities using the B. subtilis wild-type strain UD1022 and its corresponding mutant strain UD1022eps−TasA, which is defective in exopolysaccharide (EPS) and TasA protein production. Results: qPCR revealed that the B. subtilis UD1022eps−TasA− strain has a diminished capacity to colonize tomato roots in soils with diluted microbial diversity. The analysis of bacterial β-diversity revealed significant differences in bacterial and fungal community structures following inoculation with either the wild-type or mutant B. subtilis strains. The Verrucomicrobiota, Patescibacteria, and Nitrospirota phyla were more enriched with the wild-type strain inoculation than with the mutant inoculation. Co-occurrence analysis revealed that when the mutant was inoculated in tomato, the rhizosphere microbial community exhibited a lower level of modularity, fewer nodes, and fewer communities compared to communities inoculated with wild-type B. subtilis. Conclusion: This study advances our understanding of the EPS and TasA genes, which are not only important for root colonization but also play a significant role in shaping rhizosphere microbiome assembly. Future research should concentrate on specific microbiome genetic traits and their implications for rhizosphere colonization, coupled with rhizosphere microbiome modulation. These efforts will be crucial for optimizing PGPR-based approaches in agriculture. |

| Conteúdo: | Abstract: Recent technological advances have allowed the production of many studies on evapotranspiration, resulting in improvements in reference evapotranspiration estimates and crop coefficients with remote sensing data. However, these two areas of research often work independently, producing valuable studies, but without an effective integration to predict actual evapotranspiration directly, without the need for weather stations. Thus, this study aimed to model actual evapotranspiration in sugarcane crop using machine learning techniques, independently of weather stations and thermal sensor data. To achieve this goal, data from the OLI (Operational Land Imager) and TIRS (Thermal Infrared Sensor) sensors aboard the Landsat-8 and 9 satellites were used to produce the variable observed from the METRIC model, and data from the Sentinel-2A and 2B satellites, NASA POWER, WorldClim and astronomical variables, latitude, elevation, day of the year and month were used to generate the explanatory variables and feed 13 machine learning models for three different biomes: Atlantic Forest, Caatinga and Cerrado. The results indicated that the brnn (Bayesian regularized neural networks) model with R2 and RMSE of 0.73 and 1.10, respectively, and the XgbLinear (extreme gradient boosting – linear method) model, which obtained values of 0.74 and 1.25 for these metrics, in that order, showed the best overall performance. Specific analyses indicated that brnn was superior for cultivated areas in the Atlantic Forest and Caatinga biomes, while XgbLinear was superior in the Cerrado biome. These results show that machine learning algorithms are able to predict actual evapotranspiration without the need for using weather stations and thermal data. |

| Conteúdo: | Abstract: This study aimed to encapsulate Talaromyces amestolkiae colorants in maltodextrin and chitosan microparticles using the spraydrying technique and to evaluate the biopolymers’ capacities to protect the fungal colorant against temperature (65 °C) and extreme pH (2.0 and 13.0). The compact microparticles exhibited smooth or indented surfaces with internal diameters ranging between 2.58–4.69 μm and ζ ~ −26 mV. The encapsulation efficiencies were 86 % and 56 % for chitosan and maltodextrin microparticles, respectively. The shifted endothermic peaks of the free colorants indicated their physical stabilization into microparticles. The encapsulated colorants retained most of their absorbance (compared to the 0 h) even after 25 days at 65 °C. Contrary, the free colorant presented almost no absorbance after 1 day under the same conditions. Colorants in chitosan and maltodextrin matrices also partially maintained their colorimetric and fluorometric properties at acidic pH. However, only maltodextrin improved the resistance of the red colorant to alkaline environments. For the first time, the potential of polysaccharide-based microparticles to preserve polyketide colorants was demonstrated using 3D fluorescence. Therefore, this study demonstrated an alternative in developing functional products with natural color additives. |

| Conteúdo: | Abstract: Fusarium wilt of banana (FWB), caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc), poses an undeniable threat to global banana production. This disease has intensified in recent years, with the tropical race 4 (TR4) strain spreading rapidly. Since 2018, the number of affected countries has increased from 16 to 23, presenting a significant challenge to researchers, producers, and National Plant Protection Organizations (NPPOs) worldwide. The potential impact of TR4 in Latin America and the Caribbean (LAC) is particularly concerning. This region boasts seven of the top ten banana-exporting countries, and bananas and plantains are crucial for food security and income generation. In Colombia, where TR4 was detected in 2019, the disease has already spread from La Guajira to Magdalena, and it is currently affecting 20 large commercial export farms. In Peru, the disease was detected in 2021 and although still restricted to the northern region, flood irrigation and heavy rains associated with the Yaku cyclone, boosted pathogen spread, and more than 400 small organic banana farmers are currently affected. In Venezuela, TR4 detection occurred in 2023, with plantations across three states and five municipalities now affected. Worryingly, TR4 has also been confirmed in plantains, a staple food in the region. Current national responses in LAC primarily rely on preventive and reactive measures: preventing initial incursions and containing outbreaks to avoid further spread. However, the disease’s relentless progression suggests that its eventual presence in all banana-producing areas is likely. Therefore, exploring alternative management approaches beyond pathogen exclusion becomes crucial, both in affected and disease-free regions. This paper examines the current spread of TR4, focusing on epidemiological aspects and recent research-based management options. Key epidemiological features were highlighted, drawing practical examples from various scales (plots to landscapes) and utilizing experiences from LAC’s fight against TR4. The paper also reviews field-tested approaches in biosecurity, biological control, resistant varieties, soil health, and integrated disease management, acknowledging the specific challenges faced by smallholder settings. In each section research initiatives were analyzed, identifying gaps, and proposing directions to minimize TR4 impact and accelerate the development of sustainable solutions for managing this devastating disease. |

| Conteúdo: | Abstract: The objectives of the present study were to estimate the heritability for daily methane emission (CH4 ) and residual daily methane emission (CH4 res) in Nellore cattle, as well as to perform genome-wide association studies (GWAS) to identify genomic regions and candidate genes influencing the genetic variation of CH4 and CH4 res. Methane emission phenotypes of 743 Nellore animals belonging to 3 breeding programs were evaluated. CH4 was measured using the sulfur hexafluoride (SF6 ) tracer technique (which involves an SF6 permeation tube introduced into the rumen, and an appropriate apparatus on each animal), and CH4 res was obtained as the difference between observed CH4 and CH4 adjusted for dry matter intake. A total of 6,252 genotyped individuals were used for genomic analyses. Data were analyzed with a univariate animal model by the single-step GBLUP method using the average information restricted maximum likelihood (AIREML) algorithm. The effects of single nucleotide polymorphisms (SNPs) were obtained using a single-step GWAS approach. Candidate genes were identified based on genomic windows associated with quantitative trait loci (QTLs) related to the 2 traits. Annotation of QTLs and identification of candidate genes were based on the initial and final coordinates of each genomic window considering the bovine genome ARS-UCD1.2 assembly. Heritability estimates were of moderate to high magnitude, being 0.42 ± 0.09 for CH4 and 0.21 ± 0.09 for CH4 res, indicating that these traits will respond rapidly to genetic selection. GWAS revealed 11 and 15 SNPs that were significantly associated (P < 10−6) with genetic variation of CH4 and CH4 res, respectively. QTLs associated with feed efficiency, residual feed intake, body weight, and height overlapped with significant markers for the traits evaluated. Ten candidate genes were present in the regions of significant SNPs; 3 were associated with CH4 and 7 with CH4 res. The identified genes are related to different functions such as modulation of the rumen microbiota, fatty acid production, and lipid metabolism. CH4 and CH4res presented sufficient genetic variation and may respond rapidly to selection. Therefore, these traits can be included in animal breeding programs aimed at reducing enteric methane emissions across generations. |

| Conteúdo: | Abstract: Various sensory perceptions drive the quality and typicality of wines, with the volatile profile playing a fundamental role in the characteristics of odor, aroma and consequently flavor, which combines the smell (odor and aroma), taste, and trigeminal sensations. Efforts have been made in both the field of instrumental and sensory analysis to understand the relationship of volatile compounds with sensory attributes in omics approaches. Gas chromatography (monodimensional and two-dimensional (heartcutting and comprehensive)) associated with mass spectrometry (GC/MS, GC-GC/MS and GCxGC/MS) and chemometric tools have contributed to foodomics analyses, specifically those linked to metabolomics/volatilomics. These tools, along with the elucidation of sensory properties (sensomics), lead to advanced results in the field of flavoromics. They also help to define the best practices in both vineyard management and winemaking that enable the production of high-quality wines. The objective of this review is to report the challenges of determining the volatile profile of wines, pointing out the ways that can be followed in successful identification and quantification of volatile compounds. The state of the art of sensory evaluation methods is also addressed, providing information that helps in choosing the most appropriate sensory method to be conducted with chromatographic analysis to achieve more in-depth results in the field of flavoromics. |

| Conteúdo: | Abstract: A polyphasic approach was applied to characterize taxonomically a novel endophytic bacterial strain, designated as EP178T, which was previously isolated from Passiflora incarnata leaves and characterized as plant-growth promoter. The strain EP178T forms Gram stain-negative and rod-shaped cells, and circular and yellow-pigmented colonies. Its growth occurs at 10–37 °C, at pH 6.0–8.0, and tolerates up to 7% (w/v) NaCl. The major cellular fatty acids found were summed feature 8 (C18:1 ω7c), summed feature 3 (C16:1 ω6c /C16:1 ω7c), and C16:0, and the predominant ubiquinone was Q-9. The phylogenetic and nucleotide-similarity analysis with 16S rRNA gene sequences showed that strain EP178T belongs to Pseudomonas genus. The genomic-based G + C content was 65.5%. The average nucleotide identity and digital DNA-DNA hybridization values between strains EP178T and the closest type strain, P. oryzihabitans DSM 6835T, were 92.6% and 52.2%, respectively. Various genes associated with plant-growth promoting mechanisms were annotated from genome sequences. Based on the phenotypic, genomic, phylogeny and chemotaxonomic data, strain EP178T represents a new species of the genus Pseudomonas, for which the name Pseudomonas flavocrustae sp. nov. was proposed. The type strain is EP178T (= CBMAI 2609T = ICMP 24844T = MUM 23.01T). |

| Conteúdo: | Abstract: The recovery of degraded pastures and the increase in their capacity for storing carbon is a key strategy in Brazil’s commitment to meeting its Nationally Determined Contribution (NDC) to the international effort to halt global warming. Here we report the fluxes of CO2, N2O and CH4 gasses and their balances, obtained by the eddy covariance method, from a representative pasture area in southeast Brazil. The measurements covered more than five years, starting with the old degraded pasture, covering the renewal process and then the re-establishment of pasture. The latter only received nitrogen fertilization once after the renewal – the common practice. The net ecosystem carbon balance (NECB), which considered the sum of the net ecosystem exchange (NEEpasture) of CO2 and methane (FCH4pasture) without the cattle respiration and enteric fermentation, as well the export/import of carbon by grazing and as feces (stocking rates of 1.8 to 3.3 AU ha−1), was positive in the old pasture (236 ± 104g CO2 m−2 year−1) representing a source to the atmosphere, but a sink (negative) during the first year of the renewal (-1603 ± 122 g CO2 m−2 year−1) when it was fertilized and the recorded rainfall was normal. In the following two years it was neutral (77 ± 93 and 5 ± 100g CO2 m−2 year−1), partially a consequence of the lower rainfall received. In the fourth year it was a sink again (-736 ± 131g CO2 m−2 year−1). On average the cumulative fluxes of CH4 (42 ± 19 g CO2 eq. m−2 year−1) without the animals’ enteric fermentation and N2O (20 ±10 g CO2 eq. m−2 year−1) were small and positive, being offset by the net carbon gain. The NECB for this site covering the period of measurements was an overall source of 671 ± 254g CO2 m−2. |

| Conteúdo: | Abstract: Soil-plant simulation models have been ever more used as predictive tools to evaluate productivity and environmental impacts of agriculture practices. The aims of this work were to evaluate the STICS model’s capacity of simulate the emissions of nitrous oxide (N2O) under different management systems. And, to predict, by applying the calibrated and validated STICS model, the N2O emissions, under different management systems, in the edaphoclimatic conditions of the Brazilian Cerrado. The study was conducted in a long-term experiment at Embrapa Cerrados, located in Planaltina/DF, Brazil. The experiment started in 1995. The following land use systems were evaluated: CT - conventional tillage with disc harrow, and biannual grass/legume rotation; NT1 - No-tillage, with biannual crop rotation – soybean/sorghum; NT2 - No-tillage, with biannual crop rotation – maize/pigeon pea.Closed static chambers and gas sample analysis by gas chromatography were used to measure N2O fluxes. The model was calibrated with the data measured in the CT and NT1 treatments. The attributes used in the calibration were: growth, development and yield of crops and N2O fluxes. To test the model, data from the NT2 treatment was used. Data for all treatments were collected at the same time. After calibration and validation, the STICS model was used to predict the effects of soil management systems, conventional (CT) and no-tillage (NT) on greenhouse gas emissions and on grain and biomass crops production. The simulation was made for the period from 2021 to 2070. The STICS model performed well at simulation of the following parameters: N2O emissions, soil water dynamics, soil temperature; and leaf area, aerial biomass and grain yield of soybean and maize. The performance of the model was good for the conventional soil management system as well as in the no-tillage system. Based on the predicted increase in temperature for the period 2021–2070, we can conclude from the data generated through the STICS model that there is strong evidence that grain yield and total aerial biomass of plants will decrease. The data show that there is a rising tendency in N2O emissions over the simulated period. This is expected to occur for the two soil management systems studied (NT and CT). We believe this increase in emissions along the years is related to temperature increase and to the reduction of crop cycle. |

| Conteúdo: | Abstract: Pastures represent the main land use type in Brazil and are used for livestock production and maintenance of land ownership. Most pasture areas exhibit signs of degradation related to inadequate management, which affects pasture biomass production. Terrestrial ecosystem models are effective tools for evaluating the economic and ecological returns associated with distinct management scenarios. In this paper, a new forage module implemented in the ECOSystem MOdel Simulator (ECOSMOS) is formulated, and ECOSMOS-Forage model calibration and evaluation results were obtained for estimating tropical forage growth under continuous and rotational stocking methods subject to grazing or cutting regimes. A set of equations to simulate the daily carbon allocation, growth, senescence, and morphological characteristics of Urochloa (syn. Brachiaria) brizantha cvs. Marandu and Piatã were proposed. Biophysical and physiological parameters, including the solar radiation balance, soil water content, evapotranspiration and carbon assimilation, were calibrated and evaluated with one micrometeorological experiment. Additionally, two sets of parameters were calibrated for Marandu grass growth under continuous and rotational stocking. Based on the Marandu parameterization, a third set of parameters, thereby adjusting a few parameters, was derived for the Piatã grass under rotational stocking. The ECOSMOS-Forage model could successfully capture the energy, carbon and water fluxes and biomass dynamics during growth cycles. The net radiation, evapotranspiration and gross primary production were simulated with agreement index (d) values of 0.97, 0.89, and 0.95, respectively, during the calibration phase and 0.98, 0.90, and 0.93, respectively, during the evaluation phase. Regarding model application to simulate forage growth under rotational stocking, the model could estimate aboveground, leaf and stem dry matter accumulation levels with d values ranging from 0.91 to 0.98. Although forage growth is relatively difficult to simulate, compared with annual crops, the results suggested that the model could provide high potential for simulating tropical perennial forage grasses. |

| Conteúdo: | Abstract: Essential oils (EOs), as rumen additives, decreased CH4 emissions in in vitro trials but results from in vivo studies are still limited. We investigated the effects of Origanum vulgare (OEO) and Thymus vulgaris (TEO) EOs on in vivo methane emissions from Nellore beef cattle. Six adult rumen-cannulated Nellore cattle were used in a double 3 × 3 Latin square design. Treatments consisted of three diets containing either 3 mL OEO per kg of concentrate, 3 mL TEO/kg of concentrate, or no EO addition. The experimental period consisted of three 21 d feeding periods and methane production was measured using the sulfur hexafluoride (SF6) technique from Day 16 to Day 21 of each feeding period. Intake, total apparent digestibility (dry matter as well as neutral and acid detergent fiber), and rumen parameters (pH, ammoniacal nitrogen concentration, and short-chain fatty acids) were also evaluated. The EOs did not decrease CH4 emissions and had no effect on rumen parameters. |

| Conteúdo: | Abstract: Research organisations experience increasing demands to analyse on the multidimensional societal impacts of their activities. This leads to more reflections about the integration of organisational strategies devoted to research evaluation and impact monitoring, in order to answer societal and funder’s demands, improve research practices, and make research and innovations more transformative to society. Establishing a “culture of impact” within an organisation is driven by multiple factors and translates into a variety of changes at different organisational levels. We aim to understand what motivates agricultural research organisations to develop a culture of impact, and the consequences of this culture on research, management, and collaboration practices. For this, we analyse organisational trajectories of three research organisations: the French Agricultural Research Centre for International Development (Cirad), the Brazilian Agricultural Research Corporation (Embrapa), and the Colombian Agricultural Research Corporation (AGROSAVIA). Through a cross-analysis of these cases along the reasons to integrate impact evaluation in strategic agendas, the materialisation of a culture of impact in practice, and what it entails in terms of cognitive and practical changes within their respective staff and management structures, we highlight drivers and patterns of development of a culture of impact, and circumstances that seem to either favour or hinder its emergence. This study is unique for examining various types of changes that a culture of impact can generate among individuals, in particular. It offers valuable material to enable re-interrogate and orient a research organisation’s culture of impact’s path in accordance with organisational values, priorities, and opportunities. |

| Conteúdo: | Abstract: Understanding the mechanisms of soil organic matter (SOM) stabilization is fundamental to soil carbon sequestration and reduction of greenhouse gas emission (GEE), playing a pivotal role in the soil carbon cycle. Soil samples were collected from 1-meter trenches in no-till systems and compared to native vegetation, totalizing 256 samples from commercial farms in the Cerrado, Atlantic Forest, and Pampa Brazilian biomes. Soil fractionation (>53 µm and < 53 µm), laser-induced fluorescence spectroscopy (LIFS), and δ13C isotopic analysis were employed to investigate SOM dynamics and their relationships with soil carbon stocks. SOM presents chemical compounds more susceptible to decomposition in the surface, increasing its recalcitrance in deeper layers. Over 90 % of soil carbon is in the < 53 μm fraction, indicating organo-mineral association as the major SOM stabilization mechanism. However, in a minor extension physical protection by soil aggregation, can play a role in SOM stabilization. HLIFS from < 53 μm fraction demonstrated that SOM in these agricultural areas contains more labile compounds than in native vegetation areas, indicating recently incorporated less transformed organic material. Farms 2 and 4 (Cerrado) showed increases in carbon stocks in agricultural areas compared to native vegetation of 89 Mg C ha-1 and 24 Mg C ha-1, respectively, with distinct δ13C patterns. Farm 1 (Atlantic Forest) presented a reduction of 59 Mg C ha-1, primarily due to land use change, from native vegetation to agriculture. Farm 3 (Pampa) maintained its carbon stock, with no differences in δ13C patterns. These findings provide valuable insights into SOM stabilization for carbon sequestration, and the benefits of conservationist management practices, emphasizing the importance of generate data from on-farm research experiments. Measurements from agricultural and native vegetation areas in on-farm research across commercial farms provide real-field data to optimize protocols and support good management practices for enhancing soil carbon sequestration in tropical regions. |

| Conteúdo: | Abstract: We investigated the impact of various complex organic nitrogen sources on the submerged liquid fermentation of Beauveria bassiana, a versatile entomopathogenic fungus known for producing hydrophilic yeast-like single cells called blastospores. Specifically, we examined yeast extract, autolyzed yeast, inactive yeast, cottonseed flour, corn bran, and corn gluten meal as nitrogen compounds with different carbon-to-nitrogen (C:N) ratios. Our comprehensive analysis encompassed blastospore production, tolerance to abiotic stresses, shelf stability after drying, and virulence against mealworm larvae, crucial attributes for developing effective blastospore-based biopesticides. Notably, cottonseed flour emerged as the optimal nitrogen source, yielding up to 2.5 × 109 blastospores/mL within 3 days in a bioreactor. These blastospores exhibited the highest tolerance to heat stress and UV-B radiation exposure. The endogenous C:N ratio in blastospore composition was also impacted by nitrogen sources. Bioassays with mealworm larvae demonstrated that blastospores from cottonseed flour were the most virulent, achieving faster lethality (lower LT50) and requiring a lower inoculum (LC50). Importantly, blastospores produced with cottonseed flour displayed extended viability during storage, surpassing the retention of viability compared to those from autolyzed yeast over 180 days at 4°C. Despite differences in storage viability, both nitrogen sources conferred similar long-term blastospore bioactivity against mealworms. In summary, this research advances our understanding of the crucial impact of complex organic nitrogen selection on the phenotypic traits of blastospores in association with their intracellular C:N ratio, contributing to the production of ecologically fit, shelf-stable, and virulent propagules for effective pest biocontrol programs. |

| Conteúdo: | Abstract: One challenge of the citrus industry is the treatment and disposal of its effluents due to their high toxicity, substantial organic load, and consequent resistance to conventional biotechnological processes. This study introduces a novel approach, using electrochemical oxidation with a boron-doped diamond anode to efficiently remove organic compounds from biodegraded pulp wash (treated using the fungus Pleurotus sajor-caju.) The findings reveal that employing a current density of 20 mA cm−2 achieves notable results, including a 44.1% reduction in color, a 70.0% decrease in chemical oxygen demand, an 88.0% reduction in turbidity, and an impressive 99.7% removal of total organic carbon (TOC) after 6 h of electrolysis. The energy consumption was estimated at 2.93 kWh g−1 of removed TOC. This sequential biological-electrochemical procedure not only significantly reduced the mortality rate (85%) of Danio rerio embryos but also reduced the incidence of morphologically altered parameters. Regarding acute toxicity (LC50) of the residue, the process demonstrated a mortality reduction of 6.97% for D. rerio and a 40.88% lethality decrease for Lactuca sativa seeds. The substantial reduction in toxicity and organic load observed in this study highlights the potential applicability of combined biological and electrochemical treatments for real agroindustrial residues or their effluents. |

| Conteúdo: | Abstract: The use of fungicides in the postharvest treatment of mangoes has been widespread due to the incidence of pathogens, but awareness of the health risks arising from their use has increased, driving the search for more sustainable treatments. This study aimed to evaluate the activity of antifungal treatment of seven essential oils (EO) against four fungi that cause postharvest diseases in mangoes and define the minimum inhibitory concentration (MIC) and chemical composition, analyzed by gas chromatography (GC-MS). The results showed that the EOs of oregano, rosemary pepper, cinnamon bark, and clove inhibited 100% of the mycelial growth of the studied pathogens, with MIC ranging from 250 to 2000 μL.L−1. The main compound found in oregano was carvacrol (69.1%); in rosemary and pepper oil, it was thymol (77.2%); cinnamaldehyde (85.1%) was the main constituent of cinnamon bark, and the eugenol (84.84%) in cloves. When evaluating the antifungal activity of these compounds, thymol and carvacrol showed greater inhibitory activity against fungi. Therefore, this study showed the great potential of oregano, clove, rosemary pepper, and cinnamon bark essential oil as alternative treatments to synthetic fungicides in controlling postharvest diseases in mangoes. |

| Conteúdo: | Abstract: Umbu is a native fruit from the Brazilian Caatinga Biome, which is a source of income for families involved in extractivism. This fruit is highly perishable and production losses have been experienced. The production of sparkling wine can be a strategy for better use and to add value to this fruit. Furthermore, consumers have been attracted to innovative beverages, produced with alternative raw materials and with an exotic and pleasant aroma. The potential for producing sparkling wine from umbu was evaluated through physical-chemical, instrumental (gas chromatography with detection by mass spectrometry and olfactometry) and sensory analyses (acceptance test, Just-about-right (JAR) scale, and penalty analysis). Both the base wine and the sparkling wine meet all regulatory physicochemical parameters. The volatile profile of umbu pulp contains mainly terpenes (55%), while esters predominated in the base and sparkling wines (32 and 33%, respectively). In sparkling wines, hexanoic acid (3114 mg L−1) and linalool (1266 mg L−1) were the major compounds. Among the 26 odor-active compounds of sparkling wines are mainly ethyl esters with fruity aroma (acetate, decanoate, and 2-phenylacetate; OSME area: 4.8, 4.8, and 5.0%, respectively), and terpenes with floral notes (p-cymene, geranic oxide and linalool; OSME area: 8.5, 7.4, and 6.9%, respectively). The acceptance and purchase intention tests endorsed the commercialization expectation, although JAR scale and penalty analysis showed that the umbu aroma and sweetness may be improved. The potential of umbu for the production of sparkling wines has been proven, which satisfies the current market demand for innovative beverages. |

| Conteúdo: | Abstract: In biotechnological methods for biodegradation, the effectiveness of detoxifying xenobiotics and recalcitrant substances in soil and water has sparked significant interest. Our study takes a unique approach by focusing on immobilizing the white-rot fungus (WRF) Pleurotus sajor-caju onto a Luffa cylindrica plant support. This innovative method aims to facilitate the mycoremediation of agro-industrial pollutant pulp wash generated by the orange industry. The immobilization process significantly increased MnP enzymatic activity, reaching 23 IU.mL−1 and Lac activity at approximately 40.5 IU.mL−1. Qualitative SEM and FTIR analyses provided insights into the microorganism’s attachment mechanism to the support, suggesting that aggregation occurs due to an affinity to the lignocellulosic structure, enhancing the production of polysaccharides responsible for biocatalyst adherence and potential reusability. Furthermore, the production of an enzymatic extract rich in ligninolytic enzymes from P. sajor-caju showcased its ability to reduce the toxicity of pulp wash. An exploration into the toxicity of citrus effluent revealed the generation of embryos with severe deformities and the inhibition of Lactuca sativa germination, even at low concentrations. Notably, post-treatment with the enzymatic extract resulted in a remarkable 90% reduction in toxicity to the trophic level of Danio rerio and lettuce seeds. This research significantly contributes to understanding fungal immobilization strategies in environmental biotechnology, emphasizing the potential of agricultural residues as sustainable inducers for enzyme production and their pivotal role in mitigating the environmental impact of agro-industrial waste. |

| Conteúdo: | Abstract: Microbial inoculation stands as a pivotal strategy, fostering symbiotic relationships between beneficial microorganisms and plants, thereby enhancing nutrient uptake, bolstering resilience against environmental stressors, and ultimately promoting healthier and more productive plant growth. However, while the advantageous roles of inoculants are widely acknowledged, the precise and nuanced impacts of inoculation on the intricate interactions of the rhizosphere microbiome remain significantly underexplored. This study explores the impact of bacterial inoculation on soil properties, plant growth, and the rhizosphere microbiome. By employing various bacterial strains and a synthetic community (SynCom) as inoculants in common bean plants, the bacterial and fungal communities in the rhizosphere were assessed through 16 S rRNA and ITS gene sequencing. Concurrently, soil chemical parameters, plant traits, and gene expression were evaluated. The findings revealed that bacterial inoculation generally decreased pH and V%, while increasing H+Al and m% in the rhizosphere. It also decreased gene expression in plants related to detoxification, photosynthesis, and defense mechanisms, while enhancing bacterial diversity in the rhizosphere, potentially benefiting plant health. Specific bacterial strains showed varied impacts on rhizosphere microbiome assembly, predominantly affecting rhizospheric bacteria more than fungi, indirectly influencing soil conditions and plants. Notably, Paenibacillus polymyxa inoculation improved plant nitrogen (by 5.2%) and iron levels (by 28.1%), whereas Bacillus cereus boosted mycorrhization rates (by 70%). Additionally, inoculation led to increased complexity in network interactions within the rhizosphere (∼15%), potentially impacting plant health. Overall, the findings highlight the significant impact of introducing bacteria to the rhizosphere, enhancing nutrient availability, microbial diversity, and fostering beneficial plant-microbe interactions. |

| Conteúdo: | Abstract: Mangroves are coastal environments that provide resources for adjacent ecosystems due to their high productivity, organic matter decomposition, and carbon cycling by microbial communities in sediments. Since the industrial revolution, the increase of Greenhouse Gases (GHG) released due to fossil fuel burning led to many environmental abnormalities such as an increase in average temperature and ocean acidification. Based on the hypothesis that climate change modifies the microbial diversity associated with decaying organic matter in mangrove sediments, this study aimed to evaluate the microbial diversity under simulated climate change conditions during the litter decomposition process and the emission of GHG. Thus, microcosms containing organic matter from the three main plant species found in mangroves throughout the State of São Paulo, Brazil (Rhizophora mangle, Laguncularia racemosa, and Avicennia schaueriana) were incubated simulating climate changes (increase in temperature and pH). The decay rate was higher in the first seven days of incubation, but the differences between the simulated treatments were minor. GHG fluxes were higher in the first ten days and higher in samples under increased temperature. The variation in time resulted in substantial impacts on α-diversity and community composition, initially with a greater abundance of Gammaproteobacteria for all plant species despite the climate conditions variations. The PCoA analysis reveals the chronological sequence in β-diversity, indicating the increase of Deltaproteobacteria at the end of the process. The GHG emission varied in function of the organic matter source with an increase due to the elevated temperature, concurrent with the rise in the Deltaproteobacteria population. Thus, these results indicate that under the expected climate change scenario for the end of the century, the decomposition rate and GHG emissions will be potentially higher, leading to a harmful feedback loop of GHG production. This process can happen independently of an impact on the bacterial community structure due to these changes. |

| Conteúdo: | Abstract: The advancement of fungal biocontrol agents depends on replacing cereal grains with low-cost agro-industrial byproducts for their economical mass production and development of stable formulations. We propose an innovative approach to develop a rice four-based formulation of the benefcial biocontrol agent Trichoderma asperelloides CMAA1584 designed to simulate a micro-bioreactor within the concept of full biorefnery process, afording in situ conidiation, extended shelf-life, and efective control of Sclerotinia sclerotiorum, a devastating pathogen of several dicot agricultural crops worldwide. Rice four is an inexpensive and underexplored byproduct derived from broken rice after milling, capable of sustaining high yields of conidial production through our optimized fermentation-formulation route. Conidial yield was mainly infuenced by nitrogen content (0.1% w/w) added to the rice meal coupled with the fermentor type. Hydrolyzed yeast was the best nitrogen source yielding 2.6× 109 colony-forming units (CFU)/g within 14 days. Subsequently, GControl, GLecithin, GBreak-Thru, GBentonite, and GOrganic compost+Break-Thru formulations were obtained by extrusion followed by air-drying and further assessed for their potential to induce secondary sporulation in situ, storage stability, and efcacy against Sclerotinia. GControl, GBreak-Thru, GBentonite, and GOrganic compost+Break-Thru stood out with the highest number of CFU after sporulation upon re-hydration on water-agar medium. Shelf-life of formulations GControl and GBentonite remained consistent for>3 months at ambient temperature, while in GBentonite and GOrganic compost+Break-Thru formulations remained viable for 24 months during refrigerated storage. Formulations exhibited similar efcacy in suppressing the myceliogenic germination of Sclerotinia irrespective of their concentration tested (5× 104 to 5× 106 CFU/g of soil), resulting in 79.2 to 93.7% relative inhibition. Noteworthily, all 24-month-old formulations kept under cold storage successfully suppressed sclerotia. This work provides an environmentally friendly bioprocess method using rice four as the main feedstock to develop waste-free granular formulations of Trichoderma conidia that are efective in suppressing Sclerotinia while also improving biopesticide shelf-life. |

| Conteúdo: | Abstract: Entomopathogenic fungi (EPF) can be defined as beneficial multifunctional eukaryotic microorganisms that display pivotal ecological services in pest management, with some species possessing the special ability to establish mutualistic relationships with plants. Mass production of these fungi is critical to support affordable widespread commercialization and worldwide field application. Among the mass production methods explored mainly by industry, submerged liquid fermentation is a robust and versatile technology that allows the formation of different types of propagules designated for various applications in pest control. Many hypocrealean EPF are easily culturable on artificial substrates by producing single-celled structures (hyphal bodies, blastospores, and submerged conidia) or multicellular structures (mycelium and microsclerotia). Less frequently, some EPF may form environmentally resistant chlamydospores, but these structures have almost always been overlooked. A continued research pipeline encompassing screening fungal strains, media optimization, and proper formulation techniques aligned with the understanding of molecular cues involved in the formation and storage stability of these propagules is imperative to unlock the full potential and to fine-tune the development of robust and effective biocontrol agents against arthropod pests and vectors of diseases. Finally, we envision a bright future for the submerged liquid fermentation technology to supplement or replace the traditional solid substrate fermentation method for the mass production of many important EPF. |

| Conteúdo: | Abstract: Mango production, particularly of the Tommy Atkins variety, is prominent in the São Francisco Valley region of Northeast Brazil due to favorable conditions and year-round cultivation facilitated by irrigation and growth regulators. However, concerns arise over its significant water footprint and heavy pesticide usage, prompting a study on the gray water footprint of pesticides applied to Tommy Atkins mangoes in Sub-middle São Francisco Valley-Pernambuco, Brazil. Utilizing models by Hoekstra et al. (2011) and Paraiba et al. (2014), the study estimated the Gray Water Volume (GWV) and assessed potential water contamination using the GUS Index and GOSS method. Results suggest minimal groundwater pollution risk but moderate surface water contamination risk. The GWV ranged from 106 to 107 m3 ha-1, with the model of Paraiba et al. (2014) showing higher environmental sustainability due to considering toxicity to aquatic nontarget organisms. Despite this, both models indicate a high gray water footprint. The pesticide ranking derived from these findings can aid in selecting environmentally safer pesticide mixtures for mango cultivation, aiming to balance water protection and agricultural productivity. |

| Conteúdo: | Abstract: Microbes employ a variety of mechanisms, encompassing chemical signaling (e.g., quorum-sensing molecules) and genetic processes like horizontal gene transfer (HGT), to engage in interactions. HGT, in particular, holds a pivotal role as it facilitates the generation of metabolic diversity, thus directly or indirectly influencing microorganisms’ interactions and functioning within their habitat. In this study, we investigate the correlations between enhanced metabolic diversity through HGT and cooperative behavior in the rhizosphere. Despite the potential drawbacks of cooperative behavior, which renders it susceptible to exploitation by cheaters based on evolutionary theory, HGT emerges as a mitigating factor. It serves as a valuable and adaptive tool for survival in competitive environments, notably the rhizosphere. By initiating a comprehensive discussion on these processes combined, we anticipate achieving a profound understanding of the rhizosphere microbiome, ultimately enhancing soil microbiology management and the exploitation of this ecological niche. |

| Conteúdo: | Abstract: This study was conducted to evaluate the relationship among digestibility, residual feed intake (RFI), and enteric methane emission in growing Nellore cattle (Bos indicus) divergently classified based on RFI phenotype and breeding value (EBV-RFI). Animals (n = 122) subjected to performance testing (forage:concentrate ratio of 60:40) in two test groups were classified based on RFI. A sample of 80 animals classified as low (−0.748±0.076 kg DM/day) or high (0.775±0.075 kg DM/day) RFI was evaluated regarding feed compounds digestibility, fecal excretion, and methane emission (CH4, g/day). Statistical mixed models included fixed effects of RFI (or EBV-RFI), linear effect of initial age as covariate, and the random effects of the test group. There was no difference in the digestibility of feed compounds between the most and least efficient animals. However, dry matter intake (DMI; 6.92 vs. 8.66 kg DM/day) and feed conversion (7.93 vs. 9.42 kg/kg) were lesser in low RFI animals. On average, low RFI animals emitted 14.3 g less CH4 per day (174 vs. 188 g CH4/day); however, CH4 emission expressed as g/kg DMI (23.1 vs. 20.1) and the percentage of gross energy intake lost as CH4 (8.13 vs. 7.08%) were greater for these animals. These results showed the benefits of using more feed efficient animals in the beef production chain, i.e., animals that exhibit lower feed intake, lower fecal excretion, and lower enteric methane emission without differences in weight gain or body weight. However, the variations in feed efficiency among them cannot be explained by differences in dry matter or feed compounds digestibility. More efficient animals emit less enteric methane than less efficient animals, probably as a result of lower DMI. |

| Conteúdo: | Abstract: Modern agriculture has had to face complex environmental issues, many of which result from land use, which includes the degradation of its fertility properties. Soil quality is fundamental to the sustainability of the planet, as it also affects other natural resources. Therefore, it must be seen as a fundamental action for the sustainability of the planet and be evaluated using methodologies capable of holistically relating the environmental impacts of production systems, as does the Life cycle assessment (LCA) methodology. However, due to the lack of suitable models, LCA is still ineffective in assessing soil quality. Therefore, our objective was to evaluate the use of chemical soil quality indicators in the context of LCA, contributing new information to the debate. To this end, a set of soil quality indicators from the APOIA-NovoRural method were applied in some agricultural production systems in southern Brazil. Thus, the LCA results confirmed soil quality maintenance activities as those that most contribute to impacts, particularly in the categories of climate change, (eco)toxicities and land use. However, the indicators efficiently contributed direct information about the agricultural environment, relating them to the impacts estimated by the LCA. Therefore, the use of indicators makes it possible to improve soil management by adjusting chemical parameters, accurately contextualizing activities, and use of inputs to the real conditions of the area assessed. Thus, we demonstrate that indicators can be useful in providing information for agricultural environmental management in interrelation with LCA, whose application alone is not yet capable of achieving such results. |

| Conteúdo: | Abstract: Coconut cultivation faces serious challenges caused by pests and diseases, whose targets are often not reached by conventional application methods such as spraying and soil application. New control strategies, such as vegetative endotherapy, have emerged, but knowledge gaps persist regarding many aspects, especially in pesticide translocation within palm trees, which is crucial for an efficient practical field application. This study investigated the translocation of a mixture of commercial insecticides and fungicides—difenoconazole, imidacloprid, thiabendazole, cyproconazole, thiamethoxam, spirodiclofen, and carbosulfan—applied via pressurized and nonpressurized endotherapeutic methods to coconut stems. This assessment aimed to quantify the concentrations of pesticide translocation through the stem, from the application site to the plant canopy. Due to the difficulty of applying the solution to the instrument used for pressurized endotherapy, the solution had to be diluted and used at a lower volume. In experimental field conditions, stem samples were assessed at 50 and 100 cm above the application point following endotherapy treatments conducted over a period ranging from 2 to 45 days. The analyses were performed using LC-MS/MS. In the pressurized method, the highest concentrations were observed for difenoconazole (1684 µg kg−1), imidacloprid (1278 µg kg−1), and thiabendazole (781 µg kg−1). Conversely, in the nonpressurized method, the highest concentrations were recorded for imidacloprid (5803 µg kg−1), followed by difenoconazole (3660 µg kg−1) and thiabendazole (2598 µg kg−1). To address the issue with formulation conditions in the pressurized method and to allow a comparison between the two application methods, we simulated extrapolated results for comparison with the nonpressurized method. This evaluation aimed to evaluate both methods under similar formulation conditions (volume and concentration). The results predicted that if the solution had not been diluted, the pressurized method would present the best translocations, mainly near the plant canopy, except for carbofuran. All pesticides were translocated independently of their physical–chemical properties or formulation. No pesticide residues were detected in the coconut water and pulp up to 120 days after the endotherapy application. |

| Conteúdo: | Abstract: Objective: To estimate the water volumes of the main components of BH in a Haplic Cambisol in forests and pastures in the Bonfim River basin, mountainous region of RJ. Theoretical framework: The water balance (BH) accounts for the volumes of water input and output in a given space (Haplic Cambisols under forests and pastures). Method: The study period was 01/01/2000 and 12/31/2019. The HYDRUS-1D model was used to estimate water volumes in BH. Pedotransfer functions were used to determine the physical water parameters of water retention and conduction in the soil. The daily precipitation and evapotranspiration data were considered upper boundary conditions, and the lower boundary conditions were considered free drainage. Water absorption by the roots was considered as the additional factor (Sink factor) in the soil water mass balance. Results and conclusion: The average annual precipitation was 1462 mm and the potential evapotranspiration was 1026 mm. In lhe area under pastures: 83%, 7% and 9% of the total precipitated and percolated, transpired and evaporated, respectively. In areas under forests: these values were 43%, 51% and 6%. In the dry season, evapotranspiration was 20% of the total precipitation in the forest area and 8% in the pasture areas. Percolation in the dry season was 17% of the total precipitation in the pasture and 7% in the forest. In the rainy season the percolated values were 66% in the pasture and 36% in the forest. Implications of the research: Knowing the volumes of water in the components of the BH can help in decisions regarding the organization of land use and cover systems in basins of the Atlantic Forest biome. Changing soil use and cover systems alters the volumes of water percolated or evapotranspired. Originality/value: Estimating the water volumes in the BH components in pasture and forest allows predicting the effects of climate change and land use and their consequences. |

| Conteúdo: | Abstract: Honey from stingless bees has parameters that are different from those produced by Apis mellifera. These differences have led to studies of honey conservation techniques. In this context, it is necessary to evaluate whether the use of different conservation processes impacts the quality and chemical composition of this type of honey. The aim of this study was to conduct sensory analysis and determine the chemical profile, quality, and antioxidant activity of S. depilis honey subjected to different conservation processes. The physicochemical characteristics were determined in the fresh sample (time-point zero sample) and after freezing, pasteurization, dehumidification and maturation for 180 days. The reducing sugar, apparent sucrose, total acidity, moisture, water-insoluble solids, minerals, diastatic activity, Brix, color and hydroxymethylfurfural (HMF) levels were determined. These samples were also evaluated for their volatile composition and sensory aspects. After 180 days, the processed honeys showed changes in the phenolic content, and dehumidification was the treatment that most interfered with the phenolic content of the samples. The physicochemical properties that presented significant differences were the acidity, moisture, diastatic activity and color for the matured honey and the HMF levels in the dehumidification and pasteurization treatments. The main volatile compounds differed in each treatment in relation to the untreated honey. The sensory acceptance test showed significant differences for some of the attributes evaluated and the preference of consumers was for the untreated honey. |

| Conteúdo: | Abstract: Herbicides are essential tools for the phytosanitary security of agricultural areas, but their excessive use can cause problems in agricultural production systems and have negative impacts on human health and the environment. The objective of this study was to present and discuss the main causes behind the increase in herbicide commercialization in Brazil between 2010 and 2020. Data from the Brazilian pesticide database, provided by the Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA), were used. In 2010 and 2020, Brazil sold 157,512 and 329,697 tons of herbicide active ingredients, respectively, representing a 128.1% increase in commercialization over 11 years. Some herbicides, such as clethodim, haloxyfop-methyl, triclopyr, glufosinate, 2,4-D, diclosulam, and flumioxazin, showed increases in sales volumes between 2010 and 2020 of 2672.8%, 896.9%, 953.5%, 290.2%, 233.8%, 561.3%, and 531.6%, respectively, percentages far exceeding the expansion of Brazil’s agricultural area. The primary reason for this sharp increase in herbicide sales was the worsening cases of weeds resistant and tolerant to glyphosate, with species such as Conyza spp., Amaranthus spp., Digitaria insularis, and Eleusine indica standing out. This situation created the necessity of the use of additional herbicides to achieve effective chemical control of these weed species. |

| Conteúdo: | Abstract: Amblyomma ticks pose a signifcant public health threat due to their potential to transmit pathogens associated with rickettsial diseases. (E)-2-octenal, a compound found in donkeys (Equus asinus), exhibits strong repellent properties against Amblyomma sculptum nymphs under laboratory conditions. This study assessed the efectiveness of the (E)-2-octenal in wearable slow-release devices for personal human protection against Amblyomma ticks under natural conditions. Slow-release devices treated with (E)-2-octenal and untreated controls were prepared and tested on two volunteers walking through a tick-infested area in Goiania, Brazil. The experiment was conducted twice daily for three series of 10 days, with each volunteer wearing two devices attached to each leg, one on the ankle and one just above the thigh. Volunteers with control and treated devices exchanged them between rounds. Also, the daily release rate of (E)-2-octenal from the slow-release devices was determined in the laboratory, increasing signifcantly from 0.77 ± 0.14 μg/day on the frst day to 9.93 ± 1.92 μg/day on the 4th day and remaining constant until the 16th day. A total of 5409 ticks were collected from both volunteers. Treated devices resulted in recovering fewer ticks (n=1,666; 31%) compared to untreated devices (control: n=3,743; 69%). (E)-2-octenal efectively repelled Amblyomma spp. larvae, A. sculptum adults, and exhibited pronounced repellency against A. dubitatum nymphs and adults. These fndings suggest the potential of (E)-2-octenal delivered by wearable slow-release devices as a green-based repellent. Further improvements, however, are necessary to provide better protection for humans against A. sculptum and A. dubitatum in feld conditions. |

| Conteúdo: | Abstract: In Coffea arabica, there is a small genetic distance between wild and bred genotypes. However, coffee genotypes express differential acclimation to multiple drought cycles, allowing them to successfully deal with water-limiting conditions. We hypothesized that bred coffee cultivars have a plant structure less sensitive to drought than wild genotypes. Plant and leaf architecture were analyzed over the coffee strata of two cultivars (Iapar 59 and Catuai 99) and two wild Ethiopia accessions (‘E083’ and ‘E027’) grown under rainfed conditions and irrigation. During two consecutive productive years, evaluations were taken at leaf and berry expansion (BE1 and BE2) and harvest (BH1 and BH2) phenophases. The plant canopy was divided into up to four strata of 40 cm of thickness. Topological and geometric coding of coffee trees was performed in three botanical scales - metamers, branches, and plants in multiscale tree graphs (MTGs), following the VPlants modeling platform. Leaf and branch area per plant increased with tree structure development, being always significantly higher in irrigated than in rainfed plants over all phenophases. The individual leaf area was the least sensitive to water regime in Catuai 99, while the 2nd order axis elevation - angle in relation to horizontal plane, ranging from 0 degrees to 90 degrees - of bred cultivars was less sensitive to drought than in ‘E083’. This finding partially corroborated our hypothesis that orchestrated reprograming of leaf/branch responses over the vertical plant profile were less sensitive to water availability in cultivars than in wild accessions. Leaves of 2nd to 4th-order branching were roughly plagiophile, while the 1st-order leaves were classified as extremophiles. When the coffee leaves were planophile, irrespective of genotype, this pattern was found at the lowest, 1st plant stratum, and the newest developed 4th stratum. Such responses were not obligatorily related to water regime, similar to branch elevation - with exception of ‘E083’, very sensitive to drought. Taken together, our data suggest that the leaf and branch elevations in C. arabica were more influenced by light distribution through the canopy profile - i.e., self-shading - than by water availability. |

| Conteúdo: | Abstract: Cancer is a complex disease that can also affect the younger population; however, it is responsible for a relatively high mortality rate of children and youth, especially in low- and middle-income countries (LMICs). Besides that, lipidomic studies in this age range are scarce. Therefore, we analyzed blood serum samples from young patients (12 to 35 years) with bone sarcoma (osteosarcoma) and compared their lipidomics to the ones from the control group of samples, named healthy control (HC group), using NMR and LC-MS techniques. Furthermore, differences in the lipidomic profiles between OS patients with and without metastasis indicate higher glycerophosphocholine (GPC) and glycerophospholipid (GPL) levels in osteosarcoma and increased cholesterol, choline, polyunsaturated fatty acids (PUFAs), and glycerols during the metastasis. These differences, detected in the peripheral blood, could be used as biomarkers for liquid biopsy. |

| Conteúdo: | Abstract: Most studies concerning biochar, which can enhance chemical, physical, and biological soil qualities and increase crop yields, are short-term experiments in controlled environments with temperate regions and sandy soils. Biochar amendment benefits for clayey soils in tropical climate regions are uncertain. Herein, field conditions in clayey soil were investigated for 28 months. Eucalyptus biochar was obtained from charcoal production and incorporated in soil with disc plows (0.00–0.20 m). Treatments comprised six single biochar application amounts–0 (control), 10, 20, 30, 40, and 50 Mg·ha-1. The experiments were conducted in April 2016, and corn was cultivated in 2016/17 and 2017/18. Soil samples were collected in 2018 for macro/micronutrient, bulk density, porosity, macroporosity, microporosity, water availability, and soil penetration resistance evaluations in the 0.00–0.05-, 0.05–0.10-, 0.10–0.20-, 0.20–0.30-, and 0.30–0.40-m layers. Chemicals P, K and Ca increased compared to the control. The K and Ca increases were related to the biochar composition (6% K and 2% Ca). Soil bulk density decreased by 0.07 kg·dm-3, and macro/microporosity (total porosity) increased linearly by 2.5% in the 0.05–0.10-m layer with increasing biochar application amount. Soil penetration resistance was unaffected. For each 1 Mg·ha-1 of biochar applied, a 500-L·ha-1 increase in available water occurred, which may be important for crops with low water demand and to overcome water restriction periods. |

| Conteúdo: | Abstract: Important public and private initiatives to map agricultural lands and natural resources have been carried out in Brazil to support land use planning. Some studies indicate that Brazil still has up to 109.7 million hectares of cultivated pastures with some level of degradation, representing around 60% of the total pasturelands, estimated at 177 million hectares. This study aimed to gather, process, and analyze publicly available databases to generate quantitative and spatial information about the potential of Brazilian degraded pastures for agricultural expansion. We considered data related to the natural agricultural potential, restrictions imposed by special areas (indigenous lands and Afro-Brazilian “quilombola” settlements), areas with high biodiversity conservation priorities, infrastructure such as distance between major highways and availability of warehouses, current ag- ricultural areas, and the information made available by Agricultural Climate Risk Zoning. The re- sults indicated the existence of approximately 28 million hectares of planted pastures with interme- diate and severe levels of degradation that show high potential for agricultural crops. These areas could increase the planted areas with grains in Brazil by approximately 35% in relation to the total area used in the 2022/23 crop season. |

| Conteúdo: | Abstract: Global fruit and nut yields are affected by shortfalls in pollinator populations, and pollen limitation is most prevalent among tropical, bee-pollinated and self-incompatible plants. Macadamia is a subtropical, bee-pollinated crop in which some cultivars have been found to be highly outcrossing. We aimed to determine the extent of outcrossing and its effects on nut quality across a wide range of international macadamia cultivars in three countries. We sampled fruit from 19 macadamia cultivars across 23 sites in Australia, Brazil and South Africa. We used genotype-by-sequencing and MassARRAY methods to assign paternity to individual fruit and we assessed pollen-parent effects on nut quality. Macadamia was highly outcrossing, producing 80–100% of fruit by cross-pollination, at 17 of the 23 sites. Mixed mating (41–72% outcrossing) was identified at five sites, and low outcrossing (10%) was identified in one cultivar at one site where it was isolated from other flowering macadamia trees. Outcrossed fruit often had significantly better quality than selfed fruit, with 1.61–3.39 g higher nut-in-shell mass, 0.53–1.55 g higher kernel mass, 3.3–6.4% higher kernel recovery, and 3.0–3.5% higher oil concentration. The differences in kernel recovery equated to differences in value of USD 433–841 per ton of nut-in-shell at prices of USD 3000 per ton. In summary, macadamia cultivars were mostly highly outcrossing, and outcrossed nuts often had higher quality than selfed nuts. Growers should consider interplanting different cultivars more closely and distributing bee hives more widely to maximise cross-pollination, produce high yields, and optimise nut quality. |

| Conteúdo: | Abstract: Cemeteries are among the most polluting sources of groundwater and surface water in the world. Necro-leachate, a liquid released during the putrefaction of corpses, is the main culprit of such pollution. Among the compounds in this liquid are the potentially toxic amines cadaverine and putrescine, which are still poorly understood in terms of the environmental health risks they pose. This study evaluated the acute toxicity of cadaverine and putrescine, using efficient contamination bioindicators of aquatic environments. Danio rerio and Daphnia magna were exposed to both amines individually or in a mixture. Acute toxicity (LC50) was then observed in both organisms after exposure to the amines individually. Cadaverine showed higher lethality for D. magna (LC50 – 9.5 mg. L−1) and D. rerio (LC50—335.5 mg. L−1) than did putrescine (LC50—36.7 mg. L−1 and LC50- 452.6 mg. L−1, respectively). In embryotoxicity tests with D. rerio (hatching rate and malformations), delayed hatching, vertebral column malformations, and pericardial edema were observed after exposure to an amine mixture. However, co-exposure to cadaverine and putrescine was not toxic to D. magna. The results of this study confirmed the efficiency of the bioindicators used to assess contaminants in cemeteries and raised awareness of the toxic potential of cadaveric decomposition by-products. |

| Conteúdo: | Abstract: Stingless bees (Apidae, Meliponini) comprise a group of eusocial bees with great potential for use in greenhouse pollination. However, low light and increased temperature in these protected systems can compromise bee performance. This study evaluated the effect of reduced light incidence and intensity in the spectral range of ultraviolet (∼ 345 nm) and green (∼ 540 nm) and increased temperature on bee acclimation and foraging behaviour of three tropical stingless bee species (Melipona quadrifasciata, Frieseomelitta varia, and Scaptotrigona cf. postica) in experimental arenas. For M. quadrifasciata foraging was more frequent in the mild-temperature treatments and was not affected by UV and green light reduction. However, Frieseomelitta varia was more active in treatments with higher light incidence and intensity in the UV and green range. In conditions of mild temperature and high luminosity, there was an increase in foraging activity for this species throughout the days of confinement. Lastly, S. cf. postica had the greatest difficulty acclimating, even under conditions of high light incidence and mild temperature. Taken together, our results show that the environmental conditions evaluated (i.e., reduced UV and green light incidence and increased temperature) differentially affected stingless bee species. These results reinforce the need for specific management strategies when using tropical stingless bees as pollinators for greenhouse crops. |

| Conteúdo: | Abstract: Stingless bees live in populous colonies that vary in size from a few hundred individuals to tens of thousands, although information on actual colony size is limited. The objectives of this study were to determine the colony size of five Amazonian stingless bee species (Melipona flavolineata, Melipona fasciculata, Scaptotrigona aff. postica, Frieseomelitta longipes, and Plebeia minima), and to identify biological parameters that covary with colony size. The number of brood cells, adult bees, and food stocks were counted under laboratory conditions, alongside field assessments of egg-laying rate and external activity of adult workers. To identify covariates of colony size, the number of adult bees was regressed against the number of brood cells, egg-laying rate, external activity of adult workers, and food stocks, and the best candidate models were ranked using the Akaike Information Criterion. Mean (±s.d.) adult populations were: in M. flavolineata, 1046 ± 185; in M. fasciculata, 593 ± 300; in S. aff. postica, 7404 ± 1391; in F. longipes, 2425 ± 1000 and in P. minima, 405 ± 254. Thus, we showed that the external activity is the biological parameter, after the number of brood cells, that presents the best relationship with the number of adult bees, which can be easily evaluated in the field. Determining colony sizes using easily measurable biological parameters are important steps to understanding stingless bee’s life histories, ecology, and evolution, and to ease their keeping and utilization for pollination. |

| Conteúdo: | Abstract: The use of Meliponini for crop pollination in protected environments is practically non-existent. One of the reasons is the difficulty of acclimatizing Meliponini to the temperature and light conditions inside greenhouses. We investigated how covering materials used in greenhouses, which filter different intensities of ultraviolet (UV) light, affect the foraging behaviors, flight orientation, attraction to walls and ceilings, and mortality of Scaptotrigona cf. postica (Letreille), Frieseomelitta varia (Lepeletier), and Melipona quadrifasciata (Lepeletier). The experiments were conducted in 5.3 m3 arenas covered with four types of plastic films that do not polarize sunlight, with UV transmittance levels ranging from 0.1 to 54%, compared to a transparent glass control. The temperature inside the arenas varied between treatments, from 27 ± 3°C to 31 ± 2°C. All three species collected resources and returned to the colony, regardless of the covering material. However, the proportion of this behavior, the number of bees attracted to the ceiling and wall, and mortality varied among treatments and/or throughout the confinement days for each species. Melipona quadrifasciata and F. varia acclimatized better to the confined environments than S. cf. postica and showed consistent resource collection behavior throughout the confinement days in all tested materials, except for the one that filtered around 90% of UV. In all three species, the mortality gradually decreased throughout the confinement days. The results indicate that the choice of covering material, considering its optical characteristics, can be crucial to ensure greater effectiveness of the pollination services provided by stingless bees in protected systems. |

| Conteúdo: | Resumo: The grain production area in the Brazilian agricultural region known as SEALBA, especially in Alagoas State, has seen significant growth in recent years. This study aims to contribute to sustainable regional development by evaluating the effects of inoculation, co-inoculation, and the application of starter mineral nitrogen (N), either individually or in combination, on soybean growth and yield. Eight field experiments were conducted from 2018 to 2021 in two municipalities within Alagoas, covering soybean cultivation areas ranging from the first to the fourth year. The experiments followed a randomized complete block design with four replications, employing a factorial arrangement of treatments. The first factor encompassed five levels related to inoculation technologies and N management: 1) Inoculation with Bradyrhizobium; 2) Inoculation with Bradyrhizobium combined with N basal fertilization; 3) Co-inoculation of Bradyrhizobium + Azospirillum; 4) Co-inoculation of Bradyrhizobium + Azospirillum + N fertilization at the base; and 5) Control treatment without microbiological inputs or nitrogen fertilizers. The second factor involved the evaluation of different soybean cultivars, with two materials assessed in 2018 and three cultivars in 2019, 2020, and 2021. Results demonstrated that seed inoculation with Bradyrhizobium led to increased soybean grain yield in first-year cultivation areas. However, N basal fertilization, commonly known as starter fertilization, did not result in yield improvements compared to the use of microbiological inputs alone.

| Conteúdo: | Abstract: Background: Thermovinification is a non-conventional winemaking practice that replaces the traditional method of grape maceration. Methods: This study evaluated the influence of thermovinification temperature on the quality of Syrah wines. The treatments included traditional winemaking with 7 days of maceration during alcoholic fermentation at 23 °C (TW—control); and thermovinification for 2 h at 55 °C (TV55), 65 °C (TV65), and 75 °C (TV75). The red wines were made through microvinification (10-litre glass). Phenolic compounds (n = 26) were quantified by high-performance liquid chromatography and a colour analysis using the CIELab/CIEL*C*h systems and a sensory analysis was conducted to evaluate the acceptability of the thermovinified wine. Results: The results indicate that thermovinification increased the content of bioactive compounds and intensified the colour of the wine, reducing L* and a*. However, the content of phenolic acids decreased, except for trans-caftaric acid, which was approximately 50 times higher. A higher temperature of thermovinification (75 °C) promoted the degradation of all anthocyanins. Among flavonols, kaempferol-3-O-glucoside, quercetin-3-β-D-glucoside, and isorhamnetin-3-O-glucoside were higher in TV65 and TV75 wines. Greater amounts of stilbenes were quantified in TV65. Among the flavan-3-ols, TV75 stood out, especially for (+)-catechin, (−)-epicatechin, procyanidin A2, and procyanidin B1. Conclusions: The thermovinification at 65 °C is optimal for minimising anthocyanin degradation and improving Syrah wine quality. |

| Conteúdo: | Abstract: Metabolites isolated from Penicillium palitans, obtained from deep sea sediments in the maritime Antarctica, were investigated for phytotoxic and antifungal activities. The fungus was submitted to solid state fermentation, and its crude extract was produced. Chromatographic separations of the P. palitans methylene chloride crude extract led to the isolation of two analogous compounds: (−)-penienone (1) and (−)-palitantin (2). The phytotoxic activity of these compounds was assessed against seeds of Lactuca sativa and Agrostis stolonifera. Both compounds demonstrated activity exclusively in the monocotyledonous model, A. stolonifera. At a concentration of 1 mg mL−1, (−)-penienone caused 100 % inhibition of seed germination, while (−)-palitantin had only moderate activity on germination and growth of seedlings at this concentration after 7 days of treatment. Against Lemna paucicostata, at 57 μM, (−)-penienone inhibited growth by 50 % (IC50). (−)-Palitantin was much less active. When evaluated for their antifungal activity against Colletotrichum fragariae, only (−)-penienone had an IC50 value of 0.3 μM. The strain P. palitans was shown to be a promising source of phytotoxic and antifungal compounds, suggesting that extremophilic fungi, such as wild Penicillium strains from Antarctica, have the potential to yield novel prototype molecules for new pesticide development. |

| Conteúdo: | Abstract: The Brazilian Cerrado biome is known for its high biodiversity, and the role of groundwater recharge and climate regulation. Anthropogenic influence has harmed the biome, emphasizing the need for science to understand its response to climate and reconcile economic exploration with preservation. Our work aimed to evaluate the seasonal and interannual variability of the surface energy balance in a woodland savanna (Cerrado) ecosystem in southeastern Brazil over a period of 19 years, from 2001 to 2019. Using field micrometeorological measurements, we examined the variation in soil moisture and studied its impact on the temporal pattern of energy fluxes to distinguish the effects during rainy years compared to a severe drought spell. The soil moisture measures used two independent instruments, cosmic ray neutron sensor CRNS, and FDR at different depths. The measures were taken at the Pé de Gigante (PEG) site, in a region of well-defined seasonality with the dry season in winter and a hot/humid season in summer. We gap-filled the energy flux measurements with a calibrated biophysical model (SiB2). The long-term averages for air temperature and precipitation were 22.5 °C and 1309 mm/year, respectively. The net radiation (Rn) was 142 W/m2, the evapotranspiration (ET) and sensible heat flux (H) were 3.4 mm/d and 52 W/m2, respectively. Soil moisture was marked by a pronounced negative anomaly in the 2014 year, which caused an increase in the Bowen ratio and a decrease in Evaporative fraction, that lasted until the following year 2015 during the dry season, despite the severe meteorological drought of 2013/2014 already ending, which was corroborated by the two independent measurements. The results showed the remarkable influence of precipitation and soil moisture on the interannual variability of the energy balance in this Cerrado ecosystem, aiding in understanding how it responds to strong climate disturbances. |

| Conteúdo: | Abstract: Analyzing the impacts of climate change on phytosanitary problems in Brazil is crucial due to the country’s special role in global food security as one of the largest producers of essential commodities. This review focuses on the effects of climate change on plant diseases and discusses its main challenges in light of Brazil’s diverse agricultural landscape. To assess the risk of diseases caused by fungi, bacteria, viruses, oomycetes, nematodes, and spiroplasms, we surveyed 304 pathosystems across 32 crops of economic importance from 2005 to 2022. Results show that diseases caused by fungi account for 79% of the pathosystems evaluated. Predicting the occurrence of diseases in a changing climate is a complex challenge, and the continuity of this work is strategic for Brazil’s agricultural defense. The future risk scenarios analyzed here aim to help guide disease mitigation for cropping systems. Despite substantial progress and ongoing efforts, further research will be needed to effectively prevent economic and environmental damage. |

| Conteúdo: | Abstract: The objective of this work was to adapt and validate a multiresidue method for pesticide analysis, to determine the influence of the current postharvest handling steps on the degradation of pesticide residues in papaya. ‘THB’ papaya of the Solo group were sampled at each postharvest handling step in the packinghouse. For the validation of the multiresidue analysis in papaya, the technique used for extraction was the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method, with modifications. Pesticide quantification was carried out using an ultra-high performance liquid chromatograph coupled to a triple quadrupole mass spectrometer with electrospray ionization (UHPLC-MS/MS). Fruit were analyzed before and after the handling procedures and were evaluated after ripening. The used methodology was successfully validated to detect the azoxystrobin, carbendazim, carbofuran, difenoconazole, imazalil, imidacloprid, flutriafol, prochloraz, pyraclostrobin, tebuconazole, thiabendazole, and thiacloprid pesticides in papaya. Fruit washing reduces azoxystrobin and difenoconazole residue levels in 78 to 90% and in 47 to 90% on fruit surface, respectively. Although the postharvest handling steps are ineffective in reducing the levels of thiabendazole, if this fungicide is applied at the appropriate rate, the residue levels will remain below the limits permitted by law.
Resumo: O objetivo deste trabalho foi adaptar e validar um método multirresíduo para análise de agrotóxicos, para determinar a influência das atuais etapas de manejo pós-colheita sobre a degradação de resíduos de agrotóxicos em mamão. Mamões ‘THB’ do grupo Solo foram amostrados em cada etapa de manejo pós-colheita, em casa de beneficiamento. Para a validação da análise multirresíduos em mamão, a técnica de extração utilizada foi o método quick, easy, cheap, effective, rugged, and safe (QuEChERS), com modificações. A quantificação foi realizada com cromatógrafo líquido de ultraeficiência, acoplado a espectrômetro de massa triplo, quadrupolo, com ionização por eletrospray (UHPLC-MS/MS). Os frutos foram analisados antes e depois dos procedimentos de manuseio e avaliados após o amadurecimento. A metodologia utilizada foi validada com sucesso para detectar os pesticidas azoxistrobina, carbendazim, carbofuran, difenoconazol, imazalil, imidacloprid, flutriafol, prochloraz, piraclostrobina, tebuconazol, tiabendazol e thiacloprid em mamão. A lavagem dos frutos reduz os níveis de resíduos de azoxistrobina e difenoconazol em 78 a 90% e em 47 a 90% na superfície dos frutos, respectivamente. Embora as etapas de manejo pós-colheita sejam ineficazes para a redução dos níveis do tiabendazol, se este fungicida for utilizado na dose adequada, os níveis de resíduos permanecerão abaixo dos limites permitidos por lei. |

| Conteúdo: | Abstract: In Brazil, the cultivation of macadamia (Macadamia integrifolia) has expanded within the nut industry. However, there is a lack of information concerning the primary macadamia diseases under Brazilian conditions, which is crucial to defining management strategies. This study aims to identify the causal agents responsible for macadamia diseases and determine their prevalence based on a 2-year survey in a representative production area in Brazil. Samples were collected from leaves, trunk sections, racemes, and macadamia fruit from November 2019 to September 2021 in Brazil. All associated microorganisms were isolated, and pathogenicity tests were conducted to fulfill Koch’s postulates. For isolates confirmed as pathogenic, morphological characterisation and molecular identification were performed. The diseases observed, along with their respective prevalence, were as follows: leaf spot caused by Neopestalotiopsis (7%), stem canker caused by Lasiodiplodia (28%), Cladosporium blight caused by Cladosporium (72%), and fruit rot caused by Colletotrichum (18%). This study marks the first reporting of the fungi species L. pseudotheobromae, C. xanthochromaticum, and Co. siamense as phytopathogens of macadamia in Brazil. Additionally, it reports C. xanthochromaticum and Co. siamense for the first time as causal agents of Cladosporium blight and fruit rot in macadamia worldwide, respectively. |

| Conteúdo: | Abstract: In 2023, a severe outbreak led to a 70% mortality rate among Cyclamen persicum plants in Holambra, São Paulo, prompting an investigation to identify the causal agent. Symptomatic plants were sampled, and the fungus, designated CMAA 1919, was isolated and identified through morphological analysis. Pathogenicity was verified via Koch’s postulates, with inoculated plants replicating wilt symptoms. To support genomic characterization of the pathogen, whole-genome sequencing was conducted using the Illumina platform. Genomic DNA was extracted, sequenced, and processed, resulting in a 48.9 Mb genome with 200x coverage and 97.5% completeness. Phylogenetic analysis positioned CMAA 1919 within a Fusarium cluster, confirming its closest relation to Fusarium oxysporum strain Fo47 (99.07% genomic similarity) and other pathogenic strains. This study presents the first genomic and morphological description of Fusarium oxysporum f. sp. cyclaminis (CMAA 1919), the causative agent of Fusarium wilt in cyclamen in Brazil. |

| Conteúdo: | Abstract: Anthropogenic interventions have had a compromising effect on environmental health, intensifying the degradation of ecosystems, and the quantity of chemical pollutants released into nature. Therefore, research areas within the scope of environmental assessments and monitoring such as ecotoxicology have contributed to the determination of the toxic potential of contaminants. A small cyprinid known as the zebrafish (Danio rerio), the use of which has exponentially grown, is an alternative vertebrate model for scientific research, mainly in the assessment of environmental risks. The species exhibits several advantages for breeding in a laboratory, in addition to presenting multi-biomarkers of environmental toxicity. Thus, this review aims to present the main characteristics and advantages of working with this species, as well as show studies related to ecotoxicology involving biomarkers of toxicity in zebrafish. The results show a progressive trend towards employing the species in environmental risk analyses, it is an increasingly recommended species in the assessment of the toxicity level of a range of chemical pollutants. The development of future technologies must contribute to scientific advancement, rendering the potential application of this model organism an even more widespread one, which will certainly help in bridging knowledge gaps in various areas of study. |

| Conteúdo: | Abstract: The objective of this work was to evaluate the application efficiency of different nozzle tips associated with increasing application rates. A field experiment was conducted in a factorial 3 × 4 randomized block design with four replicates. The first factor consisted of three types of nozzle tips (simple flat fan, hollow cone, and hollow cone with the electrification of the drops), and the second factor constituted the four application rates (50, 100, 200, and 250 L ha-1). Electrostatic technology and a hollow cone tip increased the deposited volume on leaves on the upper and medium strata of the common bean plant, regardless of the application rate used. The increase in the application rate increased the volume of spray solution captured in the upper, medium, and lower strata, the drop density, the volumetric median diameter (VMD), and the percentage of foliar coverage, regardless of the spray tip evaluated. The percentage of leaf coverage on the adaxial and abaxial leaf was not influenced by the simple fan or hollow cone spray tips, with or without the association of electrostatic technology.
Resumo: O objetivo deste trabalho foi avaliar a eficiência de aplicação de diferentes pontas de bicos associada a taxas crescentes de aplicação.

| Conteúdo: | Abstract: Brazilian biomes are important sources for environmental microorganisms, including efficient metabolic machineries, like actinomycetes. These bacteria are known for their abilities to produce many bioactive compounds, including enzymes with multiple industrial applications. The present work aimed to evaluate lignocellulolytic abilities of actinomycetes isolated from soil and rhizosphere samples collected at Caatinga, Atlantic and Amazon Forest. Laccase (Lac), lignin peroxidase (LiP), manganese peroxidase (MnP) and cellulase were evaluated for their efficiency. These enzymes have an essential role in lignin decomposition, through oxidation of phenolic and non-phenolic compounds, as well as enzymatic hydrolysis of vegetal biomass. In this sense, a total of 173 actinomycetes were investigated. Eleven (11) of them were selected by their enzymatic performance. The actinomycete AC166 displayed some activity in all analysed scenarios in terms of Lac, MnP and LiP activity, while AC171 was selected as the most promising strain, showing the following activities: 29.7 U.L-1 for Lac; 2.5 U.L-1 for LiP and 23 U.L-1 for MnP. Cellulolytic activities were evaluated at two pH conditions, 4.8 and 7.4, obtaining the following results: 25 U.L-1 and 71 U.L-1, respectively. Thermostability (4, 30 and 60 o C) and salinity concentrations (0 to 4 M) and pH variation (2.0 to 9.0) stabilities of the obtained LiP and Lac enzymatic extracts were also verified. The actinomycete strain AC171 displayed an adaptable response in distinct pH and salt profiles, indicating that bacterial LiP was some halophilic type. Additionally, the strain AC149 produced an alkali and extreme halophilic lignin peroxidase, which are promising profiles for their future application under lignocellulosic biomass at bioethanol biorefineries. |

| Conteúdo: | Abstract: The herbicide tembotrione is effective against grassy weeds constituting an important tool in sorghum crops. However, in Brazil, this herbicide is only registered for corn. This study aimed to evaluate the selectiveness of tembotrione combined with atrazine at different doses and developmental stages of grain sorghum. Two experiments were conducted in Rio Verde and Montividiu, state of Goiás, Brazil, in 2018. A randomized block design with four replications, in a 3x2+1+1 factorial arrangement, tested three developmental stages (V3, V5 and V7), two doses of tembotrione (37.8 and 75.6 g ha-1) combined with the herbicide atrazine (1,000 g ha-1), an additional treatment only with atrazine at V3 and a control, free of herbicide. Evident phytotoxicity was observed with the combination of tembotrione and atrazine at V3 and V5 stages. Symptoms included reductions in plant height, sorghum stem diameter, panicle length, and cumulative dry mass of sorghum plant shoots. However, there was no influence on thousand grains mass, regardless of application stages. Tembotrione at 37.8 g ha-1 combined with atrazine at 1,000 g ha-1 was selective for grain sorghum when applied at V7, without affecting grain yield. |

As Sementes Crioulas são variedades preservadas pelos seus guardiões ao longo de gerações, carregando heranças ancestrais e sendo elas estratégias de promoção à saúde, segurança e soberania alimentar. Pautando-se na grande importância dessas sementes, a Rede de Agroecologia do Leste Paulista (RALP) com o objetivo de fortalecer a prática dos Guardiões de Sementes dessa região criou um Grupo de Trabalho (GT) sobre o tema. Dessa forma, foi possível iniciar o mapeamento das Redes dos Guardiões de Sementes do Leste Paulista; contribuir com o intercâmbio de conhecimentos sobre Sementes Crioulas através do I Encontro sobre Sementes Crioulas da RALP, realizar oficinas participativas com os agricultores; construir uma cartilha informativa; e propor sugestões para PLEAPO-SP (Plano de Agroecologia e Produção Orgânica do Estado de São Paulo). |

| Conteúdo: | Resumo: Este estudo analisou o manejo do capim-mombaça como fonte interna de biomassa (ou matéria orgânica) em sistemas agroflorestais. O capim-mombaça é uma gramínea tropical que demonstra grande potencial para melhorar as propriedades do solo, devido ao seu sistema radicular e à sua produção de biomassa. A pesquisa foi realizada por meio de entrevistas com agricultores. Os resultados revelaram uma diversidade de práticas e percepções entre os agricultores, ressaltando a importância de considerar os contextos individuais e as necessidades específicas de cada sistema. Foram identificados elementos-chave para o manejo adequado, como o ponto de corte do capim, a altura de corte e a escolha dos maquinários. O estudo aponta para a necessidade de aprofundar a pesquisa nessa área e promover a troca de conhecimentos entre pesquisadores e agricultores, visando melhorar a produtividade, a resiliência e a sustentabilidade dos sistemas agroflorestais. |

A partir da utilização de metodologias participativas, um contínuo ciclo de diagnóstico - análise - tomada de decisões - ações foi colocado em prática visando avançar na construção da segurança hídrica, apontada pela comunidade como principal limitação à transição agroecológica. A partir da experiência foi possível constatar a situação de insegurança hídrica vivenciada no assentamento, que consideramos ser consequência da falta de políticas públicas e ações do governo para construir infraestrutura básica e fornecer condições mínimas para a produção das famílias assentadas. Nesse sentido, o fortalecimento da governança local e da atuação em redes sociotécnicas (ressaltando o protagonismo da comunidade local a partir de metodologias participativas) também se revelou essencial. |

| Conteúdo: | Resumo: Um dos principais entraves no manejo dos sistemas agroflorestais (SAF) é o tempo e custo de mão de obra no controle de espécies espontâneas. Esta pesquisa avaliou a eficiência de duas quantidades de biomassa de capim-mombaça usados como cobertura de solo no controle dessas espécies. O experimento foi instalado em um SAF do Sítio Agroecológico da Embrapa Meio Ambiente, Jaguariúna-SP. Tomando como referência o tratamento sem cobertura do solo (T0%), o tratamento com 50% (T50%) de biomassa roçada da entrelinha reduziu em 62% o número de plantas e espécies e 82% da massa fresca (MF), enquanto o tratamento 100% (T100%) da biomassa reduziu 80% das plantas, 75% das espécies e 90% da MF. Os valores inferiores desses parâmetros em T50% e T100%, quando comparados com T0%, apresentaram diferenças significativas e quando comparados entre si não apresentaram diferenças significativas. O manejo do capim mombaça utilizando metade da quantidade total foi eficiente na redução das espécies espontâneas. |

| Conteúdo: | Resumo: Este estudo teve como objetivo avaliar e comparar as variáveis microclimáticas dentro e fora de um sistema agroflorestal (SAF) biodiverso do sítio agroecológico da Embrapa Meio Ambiente, em Jaguariúna-SP. Foram coletados dados de luminosidade, temperatura e umidade relativa do ar (UR) em cinco horários em diferentes dias ao longo dos três primeiros meses de 2022. As variáveis luminosidade e temperatura do ar dentro do SAF foram inferiores e apresentaram diferenças significativas quando comparadas com as registradas fora do SAF. Já a UR apresentou comportamento inverso, sendo superior quando comparada com fora do SAF. O microclima do SAF pode minimizar danos e estresses provocados por eventos extremos de temperaturas elevadas e/ou estiagens prolongadas, contribuir para uma maior resiliência e produtividade das plantas cultivadas e, desta forma, garantir geração de renda e sobretudo segurança e soberania alimentar para os agricultores que adotam esses sistemas de produção. |

| Conteúdo: | Resumo: A agricultura periurbana não está se renovando. A nova geração de jovens rurais, sem autonomia para tomada de decisão nos negócios na propriedade, afasta-se da atividade rural, resultando numa quebra da sucessão familiar. Fruticultores familiares e periurbanos do município de Valinhos-SP enfrentam o desafio da urbanização das áreas rurais, convivendo com o alto custo da terra devido à pressão imobiliária. Por consequência, há a necessidade de agregar mais valor à produção. Este trabalho tem o objetivo de identificar oportunidades para a continuidade da agricultura periurbana no interior do estado de São Paulo, utilizando-se Valinhos como estudo de caso. A pesquisa foi realizada de forma participativa em um evento com “pais e filhos” e com entrevistas em campo. Foram definidos a partir das análises dos questionários três diferentes grupos de agricultura periurbana em Valinhos. O primeiro caracterizado por agricultores familiares (conceito stricto sensu), onde a família participa de todo o processo de produção e o jovem não tem espaço para tomar decisões. O segundo, caracterizado por agricultores familiares em “transição” para uma agricultura empresarial, onde a produção está em expansão, a família possui mão-de-obra contratada e o jovem está em busca do próprio nicho dentro da propriedade. O terceiro, a produção é gerenciada pela família e tratada de forma empresarial, com foco em produtividade e lucratividade. A mão-de-obra é terceirizada e o principal diferencial é a autonomia do jovem. Baseado nessas tipologias, a solução para a continuidade da sucessão familiar é uma política pública que foque no jovem rural, de forma a prover para a superação de suas dificuldades e promover o sucesso da agricultura familiar periurbana no interior do estado de São Paulo. |

| Conteúdo: | Resumo: Há um aumento significativo de iniciativas em redes alimentares alternativas nos últimos anos, gerando novas relações entre produção, distribuição e consumo de orgânicos, especialmente em regiões metropolitanas. Com as restrições impostas na fase mais crítica da pandemia da Covid-19, muitas redes precisaram criar alternativas de comercialização para se adaptar ao momento. O presente artigo apresenta as transformações socioeconômicas vivenciadas durante a pandemia por produtores familiares da Cooperapas, cooperativa de orgânicos de Parelheiros, na região sul da cidade de São Paulo. Foram conduzidas entrevistas com agricultoras-chave da iniciativa supracitada, por meio de questionário semiestruturado. Se por um lado, a pandemia trouxe desafios para a comercialização, por outro, gerou inovações nas formas de escoar a produção e de estar em contato com consumidores. Houve maior conscientização na sociedade sobre alimentação saudável e engajamento em ações solidárias de doação de alimentos. |

To this end, in each of four different edaphoclimatic regions, a trial was conducted consisting of six treatments as follows: four doses of B. aryabhatta , a standard dose of A. brasilense, and an absolute control, with four repetitions, totaling 24 experimental plots. The parameters evaluated were seed germination, phytotoxicity, plant height, stalk diameter, dry mass of the aerial parts and roots, and yield. The results showed that B. aryabhattai was not phytotoxic, promoted the growth of maize plants, and increased productivity at a dose of 4 mL kg-1 in a statistically similar way to the standard commercial product. Therefore, it may constitute a new inoculant for maize crop.

| Conteúdo: | Abstract: The present study evaluated the median lethal concentration (LC50-96h), risk assessment, biometrics of weight and length, and mortality of Nile tilapia Oreochromis niloticus larvae exposed to oxytetracycline (OTC). A total of 126 fish (mean weight: 32.25±3.74 mg; mean length: 13.01±0.64 mm; 7 larvae per aquarium) were utilized for the LC50-96h assessment. These fish were randomly distributed across 21 aquaria (1 L each) containing graded concentrations of OTC: 0.0, 2.01, 2.44, 3.31, 3.65, and 4.59 mg/L. Additionally, an acute stress test involving 180 fish (mean weight: 33.9±0.73 mg; mean length: 13.06±0.72 mm; 10 larvae per aquarium) was conducted, wherein the fish were subjected to air stress for 5 minutes before being randomly allocated to 18 aquaria (1 L each) and exposed to sub-lethal concentrations of OTC: 0.0, 0.03, 0.82, 1.65, 2.47, and 3.30 mg/L. Water quality parameters (temperature, pH, dissolved oxygen, conductivity, total ammonia, and total hardness) were monitored daily throughout the experiment. The LC50-96h for OTC in Nile tilapia larvae was estimated at 3.45 mg/L. Larval weight and length significantly decreased in both tests with increasing OTC exposure. Dissolved oxygen levels exhibited significant changes over 96 hours. The post-stress test revealed significant differences (P <0.05) in pH, temperature, and dissolved oxygen. Notably, pre-exposure to air stress exacerbated the toxic effects of sub-lethal OTC levels. Risk quotient analysis indicated a high potential risk for Nile tilapia larvae exposed to therapeutic OTC concentrations. |

| Conteúdo: | Resumo: A tuvira (Gymnotus spp.) é um peixe pouco utilizado para consumo, sendo mais conhecido como isca viva. Está presente nas bacias hidrográficas do Brasil, onde convive com outras espécies comerciais que são utilizadas para consumo humano. O objetivo deste trabalho foi estudar a parasitofauna de tuviras em um estabelecimento comercial. Foram realizadas visitas técnicas para obtenção de informações sobre a rotina da propriedade e para a coleta dos peixes. Analisou-se amostras do muco da pele, raspado das brânquias, intestino e estômago. Observou-se larvas de nematóides na musculatura de dois exemplares e um cisto de metacercária na pele de um exemplar. Não se observou ectoparasitos nas brânquias e na pele dos exemplares examinados. A baixa frequência de parasitos está relacionada ao bom manejo sanitário e ao monitoramento da saúde dos peixes com o acompanhamento de um veterinário. Os nematóides encontrados possuem potencial zoonótico, ressaltando a importância da continuidade dos estudos sobre diagnóstico, tratamento e prevenção das parasitoses em tuviras. |

| Conteúdo: | Abstract: The paper decribes the motivation, challenges and preliminary results of changes made to Agrotermos, Embrapa’s conceptual space, to turn it into a semantic resource encoded in standard Knowledge Organization Systems (KOS) formats in order to facilitate it’s manteinance and edition, promote its interoperability with other resources and improve the access and visibility to Brazilian Portuguese semantic resources and henceforth to Embrapa’s results in Brazilian research in Agriculture and related domains. These changes were made within the scope of a partnership established with AgroPortal, a web-based platform designed to support data integration, sharing, and analysis, and which offers tools and services to manage and use ontologies and semantic resources. Agrotermos’ infrastructure and processes are being reformulated, VocBench is being implemented as its data management tool, and its contents are being prepared and validated for publication in AgroPortal. The preliminary results of the changes to Agrotermos’ infrastructure show that both VocBench and AgroPortal largely improve editing, visualization of the semantic content and validation of mappings and alignments between vocabularies. |

| Conteúdo: | Abstract: Biocontrol agents play a pivotal role in managing pests and contribute to sustainable agriculture. Recent advancements in genetic engineering can facilitate the development of entomopathogenic fungi with desired traits to enhance biocontrol efficacy. In this study, a CRISPR-Cas9 ribonucleoprotein system was utilized to genetically improve the virulence of Beauveria bassiana, a broad-spectrum insect pathogen used in biocontrol of arthropod pests worldwide. CRISPR-Cas9-based disruption of the transcription factor-encoding gene Bbsmr1 led to derepression of the oosporein biosynthetic gene cluster resulting in overproduction of the red-pigmented dibenzoquinone oosporein involved in host immune evasion, thus increasing fungal virulence. Mutants defective for Bbsmr1 displayed a remarkable enhanced insecticidal activity by reducing lethal times and concentrations, while concomitantly presenting negligible or minor pleiotropic effects. In addition, these mutants displayed faster germination on the insect cuticle which correlated with higher density of free-floating blastospores in the hemolymph and accelerated mortality of the host. These findings emphasize the utility of genetic engineering in developing enhanced fungal biocontrol agents with customized phenotypic traits, and provide an efficient and versatile genetic transformation tool for application in other beneficial entomopathogenic fungi. |

| Conteúdo: | Resumo: O crescimento significativo de iniciativas em redes alimentares alternativas tem gerado novas relações de produção, distribuição e consumo. Com a pandemia da Covid-19, evidenciou-se a urgência da transformação dos sistemas agroalimentares em prol de práticas mais sustentáveis. O presente artigo apresenta uma análise das mudanças qualitativas na relação de proximidade e nos valores compartilhados entre agricultores e consumidores em redes de alimentos orgânicos da cidade de São Paulo. Foram conduzidas revisão de literatura e pesquisa de campo, a qual incluiu entrevistas semiestruturadas com agricultores de uma cooperativa de orgânicos e questionários estruturados com duas redes de consumo responsável. A comercialização dos orgânicos foi impactada pontualmente nos meses mais críticos da Covid-19, entretanto, esse período trouxe inovações nas formas de escoar a produção e de estar em contato com os consumidores. Se por um lado a pandemia limitou a proximidade física nas redes alimentares alternativas, por outro, gerou uma maior conscientização sobre a importância da alimentação saudável, e sua inter-relação com a agroecologia e a saúde humana, animal e ambiental. |

| Conteúdo: | Abstract: The use of simulation models is increasingly frequent in research. The greater capacity, both in memory and processing, as well as the great availability, accessibility and amount of data collected and stored, induces and sometimes makes the use of this tool mandatory. On the other hand, when calibrated, the simulation models allow the realization, in seconds and at almost zero cost, of countless estimates of future behavior, in the most different scenarios, which, otherwise, would require a lot of time and resources to be obtained. Crop growth models and climate models are among the most widespread and used in agricultural research. Some metrics have been frequently used by users of these models to assess their efficiency. However, the best techniques are not always employed. In this work, the simulation results of air and soil temperature data were analyzed by two different models: ETA-HADGEM and STICS, respectively. The metrics usually indicated: EF (modelling efficiency) and RMSE (root mean square error), were compared with results of regression analysis and sign test for bias. The introduction of bias correction was also applied and interpreted. It is concluded that the metrics, if used in isolation and without in-depth analysis of the characteristics of the simulated variables, may result in a misinterpretation of the efficiency of the models. |

| Conteúdo: | O fenômeno El Niño Oscilação Sul (ENOS) pode modificar as interações entre variáveis meteorológicas e produção das culturas agrícolas. Avaliar essas modificações por meio de modelos de simulação do crescimento das plantas permite realizar experimentos virtuais que representam diferentes condições de manejo das culturas em curto espaço de tempo. Esse trabalho objetivou investigar a existência de efeito do ENOS, medido pelo indicador Índice Oceânico Niño (ION), sobre a produtividade da soja (Glycine max L.). A produção foi estimada pelo modelo STICS (Simulateur mulTIdisciplinaire pour les Culture Standard), que simula os processos no sistema solo-planta-atmosfera, calibrado para a cultura da soja nas condições de cultivo da Embrapa Cerrados, em Planaltina, DF. O STICS simulou a produtividade da soja semeada em cada um dos 12 decêndios entre o início de setembro e o final de dezembro, sob as condições de precipitação observadas na estação meteorológica da Embrapa Cerrados, durante 47 anos, de 1974 a 2021. Com base no ION, os mesmos 47 anos foram agrupados em 5 classes do fenômeno ENOS. Calculadas as médias de produtividade em cada decêndio, para cada classe, houve significativo efeito negativo dos anos de El Niño sobre a produtividade da soja nas semeaduras de setembro e outubro. |

| Conteúdo: | Abstract: The Brazilian Forest Sector is one of the most productive in the world with a good share of the Brazilian Gross Domestic Product. The furniture sector represents about 18% of the consumption of planted wood in Brazil and employs about 35% of the workforce in the sector. They are micro and small companies that generate a lot of jobs and fix the workforce in the countryside; however, the obsolete machinery and poorly trained workforce are responsible for the low productivity and profitability of the sector. The objective of this work was to identify the main problems and point out solutions for them. The main raw material and machinery indicators were identified, as well as corrective measures for each of them. The main conclusions were that the sector must organize itself in productive poles seeking the maximum specialization or the smallest number of products per establishment.
Resumo: O Setor Florestal Brasileiro é um dos mais produtivos do mundo, contribuindo significativamente para o Produto Interno Bruto do Brasil. O setor moveleiro representa cerca de 18% do consumo de madeira plantada no Brasil e emprega aproximadamente 35% da mão de obra no setor. São micro e pequenas empresas que geram muitos empregos e fixam a mão de obra no campo; no entanto, máquinas obsoletas e mão de obra pouco treinada são responsáveis pela baixa produtividade e rentabilidade do setor. O objetivo deste trabalho foi identificar os principais problemas e apontar soluções para eles. Foram identificados os principais indicadores de matéria-prima e maquinário, bem como medidas corretivas para cada um deles. As principais conclusões destacam a necessidade de o setor se organizar em polos produtivos buscando a máxima especialização ou o menor número de produtos por estabelecimento. |

| Conteúdo: | Resumo: Entre as mudanças que a cafeicultura brasileira vem passando nas últimas décadas, destaca-se a recente transição para a produção de cafés especiais de alta qualidade. Observa-se a relevância crescente do Brasil como produtor não apenas de quantidade, mas também de qualidade, impulsionada pela diversificação e pela valorização da origem. As características ambientais influenciam significativamente a qualidade do café. Realça-se a influência do clima, do relevo e dos solos na qualidade do café Arábica, com ênfase na altitude e latitude como fatores comprovadamente determinantes dessa qualidade. Em razão das mudanças climáticas, são diversos os desafios enfrentados pela cafeicultura. Existe uma demanda constante de adaptação e, portanto, a necessidade de pesquisas com abordagens inovadoras, que possibilitem melhor compreensão da interação do ambiente com a qualidade. Assim, fazem-se necessários mais estudos sobre a interação entre solo e qualidade do café, explorando a mineralogia da argila como indicador potencial. |

| Conteúdo: | Abstract: Cyclamen (Cyclamen persicum Mill.) is an ornamental plant that is highly susceptible to pathogens, requiring high amounts of phytosanitary products. Therefore, the development of more sustainable alternatives has been required. The present study aimed to analyze the effect of C. canadensis root extract (aqueous and with dichloromethane) applied via foliar or soil, in C. persicum, on gas exchange and the SPAD index and on the biomass of cyclamen. The aqueous extract treatment increased net CO2 assimilation, the transpiration rates, and instantaneous carboxylation efficiency. The water use efficiency values were reduced in the treatments with both extracts. The greatest increases in the SPAD index were provided by the aqueous extract. The cyclamens that received the aqueous extract applied in soil or the dichloromethane extract applied in leaves showed an increase in total biomass and number of leaves. To identify the compounds present in the extracts, CG-MS and LC-MS/MS analyses were performed. The positive effects obtained indicated a high biostimulant effect of C. Canadensis. Thus, the root extracts of C. Canadensis, particularly the aqueous extracts, have the potential to be used to reduce the use of mineral fertilizers and pesticides, promoting agroecological practices and contributing to sustainable agriculture. |
