| Conteúdo: | Abstract: Glycerol is a by-product of biodiesel. It offers a suitable additive in fabricating fuel-grade solids. However, studies on biomass-glycerol frameworks for energy generation are still emerging topics, driving the need to conduct further experiments and trials to develop alternatives (e.g., non-wood pellets and co-pelleting lines) and understand relationships between raw materials, products, and processes. We, therefore, analyzed whether adding glycerol to agroindustrial residues of bioethanol, namely sugarcane bagasse (first-generation) and lignocellulosic cake (second-generation), could develop suitable agropellets for heating and power. We combined sugarcane bagasse and lignocellulosic cake at 100/0, 75/25, 50/50, 25/75, and 0/100 (wt%, dry basis) for single and hybrid solid biofuels. We mixed them with glycerol at 0, 1, 2, and 3 wt% for a controllable addition and then pelletized them on an automatic press at 200 MPa and 150 °C. We assessed the models for glycerol-containing agropellet for standard fuel properties, such as water, volatile matter, fixed carbon, bulk density, and calorific value. In addition, we conducted thermogravimetry and energy-dispersive x-ray spectroscopy to provide further information about their thermal stability and decomposition, external morphology, and propensity to slagging and fouling. We obtained evidence for sugarcane bagasse and lignocellulosic cake developing high-quality pellets. Their products could be as dense (1161.5–1277.3 kg m−3) and energetic (20.30–21.75 MJ kg−1) as premium-grade wood biofuels; hence, they can offer stakeholders excellent solutions to address high-throughput pelleting lines and generate heat and power in the strictest residential and commercial combustion systems. Blending these materials at 25/75 (wt%, dry basis) could develop a lower degree of compactness of 1135.55 kg m−3. However, introducing glycerol up to 2%wt to such a mixture could increase it to 1162 kg m−3 while maintaining its calorific feature. As a result, it enhanced energy density from 24.1 to 27 GJ m−3. At 3 wt%, however, such an additive can limit technical performance because of its lubricating feature. In addition, it can increase the degree of roughness on the surface, making it easier for samples to reabsorb isothermally available water from the surroundings, implicating low-grade fuels. Furthermore, it can reduce heat transport while increasing physical deposits (i.e., foul and slag) during combustion, as it contained 2.9% inorganic salts. However, its impurities cannot be a limiting factor to the utilization of agropellets in boilers since they only generated 1.3% residue. Therefore, we advanced the field’s prominence in adding glycerol to non-woody materials for pelletization and co-densification as a relatively new topic. Stakeholders may benefit from our products to address high-throughput energy-producing systems while valorizing waste. |

| Conteúdo: | Abstract: Understanding the genetic diversity and mechanisms underlying genetic variation in pathogen populations is crucial to the development of effective control strategies. We investigated the genetic diversity and reproductive biology of Colletotrichum graminicola isolates which infect maize by sequencing the genomes of 108 isolates collected from 14 countries using restriction site-associated DNA sequencing (RAD-seq) and whole-genome sequencing (WGS). Clustering analyses based on single-nucleotide polymorphisms revealed three genetic groups delimited by continental origin, compatible with short-dispersal of the pathogen and geographic subdivision. Intra- and intercontinental migration was observed between Europe and South America, likely associated with the movement of contaminated germplasm. Low clonality, evidence of genetic recombination, and high phenotypic diversity were detected. We show evidence that, although it is rare (possibly due to losses of sexual reproduction- and meiosis-associated genes) C. graminicola can undergo sexual recombination. Our results support the hypotheses that intra- and intercontinental pathogen migration and genetic recombination have great impacts on the C. graminicola population structure. |

| Conteúdo: | Abstract: The Caatinga, a Brazilian dry tropical forest that sheds its leaves seasonally, harbors diverse lignocellulose-degrading microbes as a valuable source of lignin-modifying enzymes useful for the chemical and biofuel industry. Nonetheless, the detailed process of lignin decomposition in soils is still poorly understood due to most studies focusing on the biodegradation of non-ligninolytic components of plant biomass (i.e., cellulose, hemicellulose, and oligosaccharides). Hence, the microbial dynamic was investigated in kraft lignin (KL) amended soil microcosms incubated at 45 °C for 9, 18, and 27 days. The changes in the GC-MS profile indicated rapid and complete biodegradation of lignin-derived compounds (i.e., phenol, guaiacol, paracyclophane, eugenol, benzene, ethisterone, and methadone N-oxide) by the microbial ligninolytic systems. Metabarcoding analyses showed that species richness (Chao 1 index from 14313,6 ± 338 to 7230,4 ± 1056) and diversity (H’ index from 7,9 ± 0,05 to 5,6 ± 0,6) decreased in response to KL addition. However, the bacterial diversity was stabilized from the 18th to the 27th day, shaping a soil bacterial community dominated by members of the Proteobacteria (Bordetella and Roseomonas), Firmicutes (Bacillus, Pullulanibacillus, Lysinibacillus, Cohnela, and Ornithinibacilus), and Actinobacteria (Isoptericola, Saccharomonospora, and Beutenbergia) phyla, some of which have not yet been reported as able to degrade lignin. Although the KL addition has promoted the extinction of microbial taxa, the co-occurrence networks reveal high modularity values (0.92) of the microbial structure in the 18th and 27th days of KL-amended soil microcosms, indicating metabolic plasticity even with the ecological disturbance. Some individual taxa clustering into more distinct modules might be explained by the emergence of new ecological niches resulting from the heterogeneous features of KL. Metagenome-based evidence suggests that key bacterial (Bordetella and Streptomyces), and fungal (Aspergillus) members may play synergistic ecophysiological roles in decomposing lignin-derived compounds by carrying the most genes encoding lignin-modifying enzymes belonging to the auxiliary activity (AA) family. The great increase of Aspergillus-affiliated genes of the AA9 family (log ratio of 1.46), which includes the copper-dependent lytic polysaccharide monooxygenases (LPMOs), suggests a key role in lignin-derived compounds degradation. Overall, the insights gathered herein reveal the microbial dynamics of a tropical dry forest soil in kraft lignin-amended microcosms and open perspectives for a rational exploration of potentially novel enzymes and microbial candidates for biotechnological applications. |

| Conteúdo: | Abstract: Background: Plants rely on their root microbiome as the first line of defense against soil-borne fungal pathogens. The abundance and activities of beneficial root microbial taxa at the time prior to and during fungal infection are key to their protective success. If and how invading fungal root pathogens can disrupt microbiome assembly and gene expression is still largely unknown. Here, we investigated the impact of the fungal pathogen Fusarium oxysporum (fox) on the assembly of rhizosphere and endosphere microbiomes of a fox-susceptible and fox-resistant common bean cultivar. Results: Integration of 16S-amplicon, shotgun metagenome as well as metatranscriptome sequencing with community ecology analysis showed that fox infections significantly changed the composition and gene expression of the root microbiome in a cultivar-dependent manner. More specifically, fox infection led to increased microbial diversity, network complexity, and a higher proportion of the genera Flavobacterium, Bacillus, and Dyadobacter in the rhizosphere of the fox-resistant cultivar compared to the fox-susceptible cultivar. In the endosphere, root infection also led to changes in community assembly, with a higher abundance of the genera Sinorhizobium and Ensifer in the fox-resistant cultivar. Metagenome and metatranscriptome analyses further revealed the enrichment of terpene biosynthesis genes with a potential role in pathogen suppression in the fox-resistant cultivar upon fungal pathogen invasion. Conclusion: Collectively, these results revealed a cultivar-dependent enrichment of specific bacterial genera and the activation of putative disease-suppressive functions in the rhizosphere and endosphere microbiome of common bean under siege. |

| Conteúdo: | Abstract: Background Disease suppressiveness of soils to fungal root pathogens is typically induced in the feld by repeated infections of the host plant and concomitant changes in the taxonomic composition and functional traits of the rhizosphere microbiome. Here, we studied this remarkable phenomenon for Bipolaris sorokiniana in two wheat cultivars difering in resistance to this fungal root pathogen. Results: The results showed that repeated exposure of the susceptible wheat cultivar to the pathogen led to a signifcant reduction in disease severity after fve successive growth cycles. Surprisingly, the resistant wheat cultivar, initially included as a control, showed the opposite pattern with an increase in disease severity after repeated pathogen exposure. Amplicon analyses revealed that the bacterial families Chitinophagaceae, Anaerolineaceae and Nitrosomonadaceae were associated with disease suppressiveness in the susceptible wheat cultivar; disease suppressiveness in the resistant wheat cultivar was also associated with Chitinophagaceae and a higher abundance of Comamonadaceae. Metagenome analysis led to the selection of 604 Biosynthetic Gene Clusters (BGCs), out of a total of 2,571 identifed by AntiSMASH analysis, that were overrepresented when the soil entered the disease suppressive state. These BGCs are involved in the biosynthesis of terpenes, non-ribosomal peptides, polyketides, aryl polyenes and posttranslationally modifed peptides. Conclusion: Combining taxonomic and functional profling we identifed key changes in the rhizosphere microbiome during disease suppression. This illustrates how the host plant relies on the rhizosphere microbiome as the frst line of defense to fght soil-borne pathogens. Microbial taxa and functions identifed here can be used in novel strategies to control soil-borne fungal pathogens. |

| Conteúdo: | Abstract: Sugarcane plays an important role in electricity and sugar production and is a viable biofuel. Developing and optimizing a mechanism that can predict crop growth and yield at different spatiotemporal scales can promote the understanding of the effects of cultivation on the ecosystem, while providing options for optimizing management measures and improving the operational procedures of sugarcane growers. The main objective of this study is to integrate the sugarcane module into the ECOSystem MOdel Simulator (ECOSMOS) model and calibrate a parameter set for sugarcane genotypes groups (using different datasets); the model supports datasets that vary in complexity (from flux tower experiments to operational plots), while accounting for high genotype-byenvironment-by-management (GxExM) variability. First, we calibrated the ECOSMOS biophysical and physiological parameters for the sugarcane module using two micrometeorological experimental sites, based on eddycovariance and biomass measurements. Second, sugarcane genotypes located in different regions of contrasting climate conditions were split into two groups based on their period of harvest, i.e., early or mid-to-late harvest season, and two parameter sets were proposed. The sugarcane module was used to estimate the yield of numerous plots, using two different parameter sets, namely, the general and regionally-specific parameter sets. The model could successfully simulate the biophysical and physiological processes of the biomass of stalks and leaves, energy and carbon fluxes, and soil-water dynamics; for Experimental Site 2, the Nash-Sutcliffe efficiency (NSE) was 0.14–0.86 and the relative root mean square error (RRMSE) was 13–112. However, the generic parameter set did not perform well in all production environments, and the difference between the observed and simulated yields ranged from 0.9 to 14.5 (Mg ha-1). Hence, a novel calibration approach adopted in this study improved the module’s accuracy, while improving the performances for all five production environments, with the difference between the observed and simulate yields being 0.3–2.2 (Mg ha-1). Although the two parameter sets can be used as a reference for sugarcane plantations in Brazil, we recommend recalibrating the model (for ensuring higher accuracy) before operational applications. Notably, the ECOSMOS-sugarcane model is emerging as a complex ecosystem model that can support the quantifications and evaluations of the effects of sugarcane plantations on the carbon and water balances in different environmental conditions, particularly in tropical regions. |

| Conteúdo: | Abstract: Sugarcane croplands account for ~70% of global sugar production and ~60% of global ethanol production. Monitoring and predicting gross primary production (GPP) and transpiration (T) in these fields is crucial to improve crop yield estimation and management. While moderate-spatial-resolution (MSR, hundreds of meters) satellite images have been employed in several models to estimate GPP and T, the potential of high-spatial-resolution (HSR, tens of meters) imagery has been considered in only a few publications, and it is underexplored in sugarcane fields. Our study evaluated the efficacy of MSR and HSR satellite images in predicting daily GPP and T for sugarcane plantations at two sites equipped with eddy flux towers: Louisiana, USA (subtropical climate) and Sao Paulo, Brazil (tropical climate). We employed the Vegetation Photosynthesis Model (VPM) and Vegetation Transpiration Model (VTM) with C4 photosynthesis pathway, integrating vegetation index data derived from satellite images and on-ground weather data, to calculate daily GPP and T. The seasonal dynamics of vegetation indices from both MSR images (MODIS sensor, 500 m) and HSR images (Landsat, 30 m; Sentinel-2, 10 m) tracked well with the GPP seasonality from the EC flux towers. The enhanced vegetation index (EVI) from the HSR images had a stronger correlation with the tower-based GPP. Our findings underscored the potential of HSR imagery for estimating GPP and T in smaller sugarcane plantations. |

| Conteúdo: | Abstract: Perfluorooctanesulfonic acid (PFOS) is a manmade chemical with several industrial applications and also a potential byproduct of many other per- and polyfluorinated substances (PFAS) in the environment. Due to the gathered evidence on its environmental persistence, long-range transport, toxicity, and bioaccumulative and biomagnifying properties, PFOS, its salts and perfluorooctane sulfonyl fluoride (PFOSF), were listed for global restriction under the Stockholm Convention on Persistent Organic Pollutants in 2009. Nevertheless, Brazil has granted an acceptable purpose exemption for using PFOSF to produce sulfluramid (EtFOSA) and to apply it as insecticide to control leaf-cutting ants of the genus Atta and Acromyrmex. Previous studies have pointed out EtFOSA as a precursor of PFOS in the environment, including in soils. Therefore, we aimed to confirm the role of EtFOSA in PFOS formation in soils representing areas where sulfluramid-based ant baits are used. A biodegradation assay was carried out by applying technical EtFOSA in triplicate samples of ultisol (PV) and oxisol (LVd) and measuring the contents of EtFOSA, perfluorooctane sulfonamide acetic acid (FOSAA), perfluorooctane sulfonamide (FOSA), and PFOS at seven moments (0, 3, 7, 15, 30, 60, and 120 days). The monitored byproducts started being noticed on the 15th day. After 120 days, PFOS yields were 30% for both soils, whereas FOSA yields were 46% (PV soil) and 42% (LVd soil) and FOSAA yields were 6% (PV soil) and 3% (LVd soil). It can be expected that FOSAA and FOSA contents will eventually be converted into PFOS in the environment and that the presence of plants could boost PFOS formation. Therefore, the ongoing extensive and intensive use of sulfluramid-based ant baits pose a considerable source of PFOS to the environment. |

| Conteúdo: | Abstract: The quality of the aquatic environment can be compromised by the practice of intensive use of pesticides in agriculture and by the misuse of veterinary drugs. Therefore, organisms that live in aquatic ecosystems may be affected due to the presence of these chemicals, through runoff, leaching and other processes. Exposure of aquatic organisms to these xenobiotics could pose health risks. Consequently, there is a growing interest in predicting the bioaccumulation of these substances in aquatic biota from experiments conducted under laboratory conditions. Studies on fish have been performed due to its importance as human food and their wide distribution in most of the aquatic environment. Thus, this article reviews the concepts on determining the accumulation of pesticides and veterinary drugs in fish. The risk regarding the consumption of fish containing residues of these chemical agents, the acceptable daily intake, the testing protocols and the analytical techniques used to determine the residues of these substances in fish tissues are discussed. An emphasis on studies involving tilapia as the test organism was included because, according to Food and Agricultural Organization (FAO), this species is one of the most cultivated in the world. |

| Conteúdo: | Abstract: Agro-industrial waste byproducts are commonly inexpensive organic nutritional sources for production of filamentous fungi, and selection of an optimal bioreactor is a key factor for attaining satisfactory biomass yield and quality. The insect-pathogenic fungus Beauveria bassiana (Hypocreales: Cordycipitaceae) has been extensively mass produced by solid-state fermentation using precooked cereal grains. Here, we propose low-cost palm oil residues as the main substrate using a cylindrical packed-column aerobic bioreactor prototype designed for conidial production of B. bassiana. Fermentation treatments using B. bassiana strain CG1229 assessed the impact of temperature, air flow, substrate moisture content, and ratio between palm fiber (PF) and palm kernel cake (PKC) on conidial yield and desiccation tolerance. Results showed significant enhanced productivity (2 ×1010 conidia g−1 dry matter) and reduced fermentation time (from 168 h to 120 h) by this method compared with the conventional tray bioreactor. Optimal substrate conditions were 60% initial moisture and 30% PF + 70% PKC content, fermentation at 26 °C with aeration rate ≥ 0.2 L min−1. Air drying conidia inside the column yielded > 95% germination. Maximum spore production was achieved in 120 h. Our findings demonstrate the feasibility of using a packed-column bioreactor for mass production of B. bassiana conidia using low-cost agricultural residues, which contributes to a sustainable production method of this biopesticide in Brazil. |

| Conteúdo: | Abstract: The typical phenolic profile in grapes is characterized by its complexity both in terms of number of diverse chemical structures and their variation during ripening. Besides, the specific phenolic composition of grapes directly influences the presence of those components in the resulting wine. In this contribution, a new method based on the application of comprehensive two-dimensional liquid chromatography coupled to a diode array detector and tandem mass spectrometry has been developed to obtain the typical phenolic profile of Malbec grapes cultivated in Brazil. Moreover, the method has been demonstrated to be useful to study how the phenolic composition in grapes evolved during a 10-week ripening period. Main detected compounds in grapes and in the wine derived from them were anthocyanins, although a good number of polymeric flavan-3-ols were also tentatively identified, among other compounds. Results show how the amount of anthocyanins present in grapes was increased during ripening up to 5-6 weeks and then decreased towards week 9.

| Conteúdo: | Abstract: Assessing the sustainability of agricultural systems encompasses complex and interchanging economic, environmental and social issues, and requires multi-criteria decision-analysis approaches. Various models have been proposed to assess agricultural sustainability considering these issues, based for example on programs for multi-attribute decision making or Fuzzy Interference Systems. However, we identify a lack of comprehensive models applicable to broad agricultural conditions in different environments and socioeconomic contexts. To fill this gap, we propose a novel, indicator-based fuzzy logic model for assessing the sustainability of agricultural systems. To test the model’s suitability, we conducted twenty-two case studies over the 2018/19 cropping season in the Brazilian agricultural-forest frontier region; the farms chosen represent the three most common farming systems there: (i) pure crop farming (crop rotation only: soybean - corn), (ii) pure livestock, and (iii) integrated farming (crop - livestock and livestock - forest). Partial indicators were built to assess the economic, environmental, and social performances of those farming systems, then were further integrated in a sustainability index. The results show higher and better-balanced performance for integrated farms, which displayed the highest sustainability index values. In contrast, livestock farms performed poorly in all dimensions and showed the lowest sustainability index. Crop farms showed higher economic, but lower social and environmental performances. These results are in contrast to the oft-perceived trade-offs among different pillars of sustainability and show that integrated systems have the potential to balance multiple sustainability objectives, by leveraging multiple subsystem synergies. The innovative fuzzy inference model proposed is suitable to deal with information at the farm level, handling different types of farming systems, and applicable to different environmental or socioeconomic contexts. Moreover, the proposed indicators and associated indices offer relevant information to policy-makers to foster the sustainable intensification of farming systems, while promoting environmental protection and the coexistence of biodiversity and the agricultural sector. |

| Conteúdo: | Abstract: Plant ingredients, when used as substitutes for animal protein ingredients, can negatively influence fish growth. Thus, feed additives have been used to enhance feed consumption, nutrient utilization efficiency and stress tolerance under intensive management conditions. One such potential feed additive in aquafeeds is poultry liver protein hydrolysate (PLPH), which is rich in essential amino acids and has in vitro antioxidant and antibacterial properties. In this study, we aimed to evaluate the effect of poultry liver protein hydrolysate as feed additive on the productive performance of Nile tilapia reared in a water recirculation system and investigate stress responses and redox status after an air exposure challenge. Nile tilapia juveniles were randomly distributed in 24 aquariums and fed plant-based diets supplemented with increasing levels of PLPH (0, 10, 20, and 40 g/kg) over a 45-day period. At the end of the experiment, we did not observe a significant effect of PLPH on productive performance variables or body indices (P > 0.05). Air exposure triggered stress responses in fish, as evidenced by an increase in blood glucose (P < 0.05). However, PLPH supplementation did not mitigate this effect (P > 0.05). Regarding redox status, a quadratic effect of PLPH supplementation was observed on malondialdehyde (P = 0.003) levels, as well as the activities of superoxide dismutase (P = 0.015), catalase (P = 0.015), and glutathione S-transferase (P = 0.001). Optimum PLPH supplementation levels were estimated at 25.14, 25.91, 22.57, and 18.83 g/kg, respectively, for these redox parameters. Increasing PLPH levels decreased carbonylated protein contents (P = 0.001) but increased hydrogen peroxide levels in the gills (P = 0.006). Although PLPH supplementation improved antioxidant enzyme activity, and attenuated protein damage, it concurrently increased reactive oxygen species production and lipid peroxidation. Further studies are necessary to elucidate the underlying mechanisms of action by which protein hydrolysates influence the redox status of fish reared under intensive management. |

| Conteúdo: | Abstract: Citric acid is an organic acid, which has been used as a feed additive because it has a reasonable cost, pleasant taste, and fast assimilation, showing positive effects on the growth and health of some livestock and aquatic species. This study aimed to evaluate the effects of increased levels of citric acid (0, 10, 20, 30, and 40 g/kg) in an isonitrogenous (280.00 g/kg of digestible protein) and isoenergetic diet (12.98 MJ/kg of digestible energy) on growth performance, body composition, apparent digestibility of nutrients and minerals, hematology, pH in stomach and intestine, and intestinal histomorphometry of Nile tilapia juveniles. Fish (n = 200, initial average weight of 14.59 ± 0.81 g) were randomly distributed in 25 experimental tanks (five replicates per treatment) and fed experimental diets over a 40-day period. Increasing levels of citric acid supplementation resulted in a decrease in the pH of the experimental diets (P = 0.021). However, no significant differences in pH levels were observed in the stomach and intestine among the treatments (P > 0.05). Citric acid supplementation did not significantly (P > 0.05) affect the growth performance variables, body composition, or the apparent digestibility coefficients (ADC) of dry matter, crude protein, gross energy, ether extract, and ash of the diets. Fish fed diets with 10 and 30 g/kg citric acid exhibited higher values for total leukocytes (P = 0.043) and total plasma protein (P = 0.019) compared to the control group. Diets supplemented with 20 g/kg citric acid showed a higher ADC value for phosphorus (P = 0.027) and calcium (P = 0.032) compared to the control. Additionally, fish fed with diets containing 20 g/kg citric acid demonstrated higher values for villus height (P = 0.002) and width (P = 0.048), crypt depth (P = 0.035), and villus: crypt ratio (P = 0.014) compared to the control group. In conclusion, the supplementation of 20 g/kg citric acid improved the availability of phosphorus and calcium and positively influenced the intestinal morphology of Nile tilapia juveniles. |

| Conteúdo: | Abstract: The operational slowness in the execution of direct methods for estimating forage mass, an important variable for defining the animal stocking rate, gave rise to the need for methods with faster responses and greater territorial coverage. In this context, the aim of this study was to evaluate a method to estimate the mass of Urochloa brizantha cv. BRS Piatã in shaded and full sun systems, through proximal sensing applied to the Simple Algorithm for Evapotranspiration Retrieving (SAFER) model, applied with the Monteith Radiation Use Efficiency (RUE) model. The study was carried out in the experimental area of Fazenda Canchim, a research center of Embrapa Pecuária Sudeste, São Carlos, SP, Brazil (21°57′ S, 47°50′ W, 860 m), with collections of forage mass and reflectance in the silvopastoral systems animal production and full sun. Reflectance data, as well as meteorological data obtained by a weather station installed in the study area, were used as input for the SAFER model and, later, for the radiation use efficiency model to calculate the fresh mass of forage. The forage collected in the field was sent to the laboratory, separated, weighed and dried, generating the variables of pasture total dry mass), total leaf dry mass, leaf and stalk dry mass and leaf area index. With the variables of pasture, in situ, and fresh mass, obtained from SAFER, the training regression model, in which 80% were used for training and 20% for testing the models. The SAFER was able to promisingly express the behavior of forage variables, with a significant correlation with all of them. The variables that obtained the best estimation performance model were the dry mass of leaves and stems and the dry mass of leaves in silvopastoral and full sun systems, respectively. It was concluded that the association of the SAFER model with the proximal sensor allowed us to obtain a fast, precise and accurate forage estimation method. |

| Conteúdo: | Abstract: An ever-growing collection of commercial biostimulants is becoming available in a wide variety of forms and compositions to improve crop performance. Given the intricate nature of deciphering the underlying mechanisms of commercial products, which typically comprise various biological components, it is crucial for research in this area to have robust tools to demonstrate their effectiveness in field trials. Here, we took a multi-attribute approach to evaluating the impact of biostimulants on crop performance. First, we assessed the impact of a biostimulant on the soil and rhizosphere microbiomes associated to crops in eight reference farms, including corn (3 farms), soybean (2), cotton (2) and sugarcane (1), in different biomes and production contexts in Brazil and Paraguay. Second, we modeled a set of integrated indicators to measure crop responses to biostimulant application, including five analytical themes as follows: i) crop development and production (9 indicators), ii) soil chemistry (9), iii) soil physics (5), iv) soil biology (6) and v) plant health (10). Amplicon 16S rRNA and ITS sequencing revealed that the use of the biostimulant consistently changes the structure of bacterial and fungal communities associated with the production system for all evaluated crops. In the rhizosphere samples, the most responsive bacterial taxa to biostimulant application were Prevotella in cotton; Prauserella and Methylovirgula in corn; and Methylocapsa in sugar cane. The most responsive fungal taxa to biostimulant use were Arachnomyces in soybean and cotton; and Rhizophlyctis in corn. The proposed integrated indicators yielded highly favorable positive impact indices (averaging at 0.80), indicating that biostimulant-treated fields correlate with better plant development and crop performance. Prominent indices were observed for indicators in four themes: soil biology (average index 0.84), crop production (0.81), soil physics (compaction reduction 0.81), and chemical fertility (0.75). The multi-attribute approach employed in this study offers an effective strategy for assessing the efficacy of biostimulant products across a wide range of crops and production systems. |

| Conteúdo: | Abstract: Titanium dioxide nanoparticles-multiwalled carbon nanotubes (TiO2−MWCNT) nanohydrid has an enhanced photocatalytic activity across the visible light with promising applications in environmental remediation, solar energy devices and antimicrobial technologies. However, it is necessary to evaluate the toxicological effects of TiO2−MWCNT towards safe and sustainable development of nanohybrids. In this work, we studied the cytotoxicity, protein corona formation and cellular internalisation of TiO2−MWCNT on fibroblasts derived from gonadal rainbow trout tissue (RTG-2) for the first time. This nanohydrid did not show any toxicity effect on RTG-2 cells up to 100 mg L−1 after 24 h of exposure as monitored by alamar blue, neutral red and trypan blue assays (in presence or absence of foetal bovine serum, FBS). Futhermore, cryo-transmission electron microscopy analysis demonstrated that TiO2 particles is attached on nanotube surface after FBS-protein corona formation in cell culture medium. Raman spectroscopy imaging showed that TiO2−MWCNT can be internalised by RTG-2 cells. This work is a novel contribution towards better understanding the nanobiointeractions of nanohydrids linked to their in vitro effects on fish cells in aquatic nanoecotoxicology. |

| Conteúdo: | Abstract: In the field of agriculture, nanopesticides have been developed as an alternative to the conventional pesticides, being more efficient for pest control. However, before their widespread application it is essential to evaluate their safe application and no environmental impacts. In this paper, we evaluated the toxicological effects of two kinds of atrazine nanoformulations (ATZ NPs) in different biological models (Raphidocelis subcapitata, Danio rerio, Lemna minor, Artemia salina, Lactuca sativa and Daphnia magna) and compared the results with nanoparticle stability over time and the presence of natural organic matter (NOM). The systems showed different characteristics for Zein (ATZ NPZ) (184 ± 2 nm with a PDI of 0.28 ± 0.04 and zeta potential of (30.4 ± 0.05 mV) and poly(epsilon-caprolactone (ATZ PCL) (192 ± 3 nm, polydispersity (PDI) of 0.28 ± 0.28 and zeta potential of −18.8 ± 1.2 mV) nanoparticles. The results showed that there is a correlation between nanoparticles stability and the presence of NOM in the medium and Environmental Concentrations (EC) values. The stability loss or an increase in nanoparticle size result in low toxicity for R. subcapitata and L. minor. For D. magna and D. rerio, the presence of NOM in the medium reduces the ecotoxic effects for ATZ NPZ nanoparticles, but not for ATZ NPs, showing that the nanoparticles characteristics and their interaction with NOM can modulate toxic effects. Nanoparticle stability throughout the evaluation must be considered and become an integral part of toxicity protocol guidelines for nanopesticides, to ensure test quality and authentic results regarding nanopesticide effects in target and non-target organisms. |

| Conteúdo: | Abstract: 1. Agricultural expansion is one of the main drivers of global pollinator loss. Paradoxically, this occurs while agriculture is becoming increasingly dependent on biotic pollination, raising concerns about food production. Integrated Crop Pollination (ICP), the use of both wild and managed pollinators in crop fields, can help conserve pollinator diversity while ensuring effective pollination services for growers. However, given the context-dependent nature of this approach, there is an urgent need to evaluate its application across different landscapes and crops. 2. We apply the ICP approach to açaí palm (Euterpe oleracea Mart.) production in the eastern Brazilian Amazon to explore effects of a native stingless bee, Scaptotrigona aff. postica (Apidae: Meliponini), and landscape-level forest conservation on yield and socioeconomic outcomes for açaí fruit growers. We assessed flower visitor assemblages and fruit production on 18 plantations across a landscape forest cover gradient, with bee colonies introduced on nine plantations. Field data were combined with information from semistructured interviews of growers to estimate yield and profit per hectare under different pollinator management scenarios. 3. Bee colonies and forest cover enhanced flower visitor abundance on palm inflorescences, but abundance increases attributed to managed bees were associated with shifts in flower visitor evenness and diversity (species richness), due to reduced visitation of wild bees near managed colonies. 4. Fruit production on inflorescences was positively related to bee abundance and bee diversity. Consequently, overall pollination performance was lower in plantations with bee colonies. This was repeated at the hectare scale, where yield and profit were associated with surrounding forest cover and not bee colonies. 5. Synthesis and applications. Managed bees can increase pollinator densities and fruit production, but the increased environmental and socioeconomic risks associated with this activity means açaí growers should prioritise forest conservation to safeguard pollination services and improve overall sustainability of açaí production in the eastern Brazilian Amazon. |

| Conteúdo: | Abstract: Phytosanitary control is essential to ensure agricultural productivity and quality. However, approaches based on scheduled use of pesticides, overuse of harmful molecules produce impacts on different types of living organisms. Integrated Pest and Disease Management (IPM-IDM) may significantly reduce the burden of pesticides in the environment. Plant resistance may also be included in the IPM-IDM and even in conventional management due to little requirement of additional knowledge and changes in agricultural practices. Robust environmental assessments using methodology of universal use, life cycle assessment (LCA), may estimate the impacts of specific pesticides that cause major damages, including remarkable category impacts. Therefore the objective of this study was to determine the impacts and (eco)toxicological effects of phytosanitary strategies (IPM-IDM including or not lepidopteran resistant transgenic cultivars) vs. the scheduled approach. Two inventory modeling methods were also applied to gather information on the use and applicability of these methods. Life cycle assessment (LCA) was applied using two inventory modeling methods: 100%Soil and PestLCI (Consensus) using data from Brazilian croplands under tropical conditions, by combining phytosanitary approaches (IPM-IDM, IPM-IDM + transgenic cultivar, conventional, conventional + transgenic cultivar) and modeling methods. Hence, eight soybean production scenarios were established. The IPM-IDM was efficient to reduce the (eco)toxicity impacts of soybean production mainly for freshwater ecotoxicity category. Due to the dynamic character of IPM-IDM approaches, the inclusion of recently introduced strategies (plant resistant and biological control to stink bugs and plant fungal diseases) may diminish even more the principal impacting substances throughout the Brazilian croplands. The PestLCI Consensus method, although its development is yet in progress, to date can be suggested to estimate the agriculture environmental impacts more properly under tropical conditions. |

| Conteúdo: | Abstract: The cattle tick, Rhipicephalus microplus (Acari: Ixodidae), is a multi-billion dollar ectoparasite of global importance affecting beef and milk production. Submerged cultures of cosmopolitan entomopathogenic fungal species of the genus Metarhizium typically produce microsclerotia that provide both long-term survival and environmental resistance. Microsclerotia hold great potential as an unconventional active propagule to control this tick under laboratory and semi-field conditions. However, heat stress caused especially by elevated temperatures poses a critical environmental constraint for the successful development and efficacy of microsclerotia under tropical conditions. First, we screened six strains of Metarhizium anisopliae, Metarhizium robertsii and Metarhizium humberi for their ability to produce microsclerotia by submerged liquid cultivation. In addition, we assessed the biological fitness and bioefficacy of dried microsclerotial pellets under amenable (27 °C) and heat-stressed (32 °C) incubation against engorged adult females of R. microplus. Microsclerotia in pelletized formulation prepared with carriers based on diatomaceous earth and microcrystalline cellulose exhibited conidial production at different extents according to the fungal strain and the incubation temperature, but most strains displayed reduced sporogenesis when exposed to 32 °C. Engorged tick females exposed to sporulated microsclerotia from pelletized M. anisopliae CG47 or IP 119 had fewer number of hatching larvae in comparison to the control group, irrespective of the incubation temperature tested. The minimum dosage of microsclerotial pellets that effectively reduced hatchability of tick larvae was estimated to be 2 mg per plate (equivalent to 6.0 kg per hectare). Metarhizium microsclerotial pellets exhibited significant tolerance to 32 °C and pronounced acaricidal activity against this economically important ectoparasite of cattle, even under simulated environmental heat stress. |

| Conteúdo: | Abstract: This study reports the isolation and identification of the endophytic fungus Exserohilum rostratum through molecular and morphological analysis using optical and transmission electron microscopy (TEM), as well as the procurement of its secondary metabolite monocerin, an isocoumarin derivative. Considering the previously observed biological activities of monocerin, this study was performed on human umbilical vein endothelial cells (HUVECs) that are widely used as an in vitro model for several different purposes. Important parameters, such as cell viability, senescence-associated β-galactosidase, cellular proliferation by using 5(6)-carboxyfluorescein diacetate N-succinimidyl ester (CFSE), apoptosis analysis with annexin, cellular morphology through scanning electron microscopy (SEM), and laser confocal analysis were evaluated after exposing the cells to monocerin. After 24 h of exposure to monocerin at 1.25 mM, there was more than 80% of cell viability and a low percentage of cells in the early and late apoptosis and necrosis. Monocerin increased cell proliferation and did not induce cell senescence. Morphological analysis showed cellular integrity. The study demonstrates aspects of the mechanism of action of monocerin on endothelial cell proliferation, suggesting the possibility of its pharmaceutical application, such as in regenerative medicine. |

| Conteúdo: | Abstract: Currently, species within the genus Akanthomyces are poorly studied and explored compared to other hypocrealean entomopathogenic fungi employed as commercial biocontrol agents. This study aimed to molecularly identify 23 Brazilian Akanthomyces strains, most originally isolated from aphids and scales (n = 22), and one from the coffee leaf rust, and further investigate their pathogenicity to six plant-sucking insects as a means to better understand their host spectra. We also explored the capacity of A. muscarius CG935 for blastospore production via liquid fermentation. Akanthomyces dipterigenus, A. muscarius, A. lecanii, and two unidentified species were recognized as naturally occurring in Brazil. Akanthomyces dipterigenus CG829 and A. muscarius CG935 were highly virulent to nymphs of Bemisia tabaci (67.5–85.4% confirmed mortality) and the aphid Aphis fabae (74.6–75.3%), but only the first strain was virulent to the mealybug Planococcus sp. (80.9%). Akanthomyces lecanii CG824 was weakly virulent to all tested insects. None of the strains were pathogenic to the thrips Caliothrips phaseoli, and all strains showed low virulence to the wooly whitefly Aleurothrixus floccosus and the scale Duplachionaspis divergens. Submerged liquid fermentation yields varied from 1.72 × 109 (day 2) to 3.90 × 109 (day 5) blastospores mL− 1 . Blastospores or aerial conidia from A. muscarius CG935, at a single concentration of 1 × 107 viable propagules mL− 1, resulted in 67.5–83.1% mortality of B. tabaci nymphs within 8 days posttreatment. Overall, these results encourage additional studies that could lead to the development of new mycopesticides based on Akanthomyces strains. |

| Conteúdo: | Abstract: Beauveria bassiana is a cosmopolitan entomopathogenic fungus that can infect over 1000 insect species. During growth inside the host, B. bassiana transitions from hyphal to yeast-like unicellular growth as blastospores. Blastospores are well suited as an active ingredient in biopesticides due to their ease of production by liquid fermentation. Herein, we investigated the impact of hyperosmotic growth environments mediated by ionic and non-ionic osmolytes on two strains of B. bassiana (ESALQ1432 and GHA) relevant to growth morphology, blastospore production, desiccation tolerance, and insecticidal activity. Polyethylene glycol (PEG200) increased osmotic pressure in submerged cultures leading to decreased blastospore size but higher blastospore yields for one strain. Morphologically, decreased blastospore size was linked to increased osmotic pressure. However, smaller blastospores from PEG200 supplemented cultures after air-drying exhibited delayed germination. Ionic osmolytes (NaCl and KCl) generated the same osmotic pressure (2.5–2.7 MPa) as 20% glucose and boosted blastospore yields (> 2.0 × 109 blastospores mL−1). Fermentation performed in a bench-scale bioreactor consistently promoted high blastospore yields when using NaCl (2.5 MPa) amended media within 3 days. Mealworm larvae (Tenebrio molitor) were similarly susceptible to NaCl-grown blastospores and aerial conidia in a dose-time-dependent manner. Collectively, these results demonstrate the use of hyperosmotic liquid culture media in triggering enhanced yeast-like growth by B. bassiana. Understanding the role of osmotic pressure on blastospore formation and fitness will hasten the development of viable commercial fungal biopesticides. |

| Conteúdo: | Abstract: Arbuscular mycorrhizal fungi form symbiotic associations with 80-90% of all known plants, allowing the fungi to acquire plant-synthesized carbon, and confer an increased capacity for nutrient uptake by plants, improving tolerance to abiotic and biotic stresses. We aimed at characterizing the mycorrhizal community in the rhizosphere of Neoglaziovia variegata (so-called `caroa`) and Tripogonella spicata (so-called resurrection plant), using high-throughput sequencing of the partial 18S rRNA gene. Both plants are currently undergoing a bioprospecting program to find microbes with the potential of helping plants tolerate water stress. Sampling was carried out in the Caatinga biome, a neotropical dry forest, located in northeastern Brazil. Illumina MiSeq sequencing of 37 rhizosphere samples (19 for N. variegata and 18 for T. spicata) revealed a distinct mycorrhizal community between the studied plants. According to alpha diversity analyses, T. spicata showed the highest richness and diversity based on the Observed ASVs and the Shannon index, respectively. On the other hand, N. variegata showed higher modularity of the mycorrhizal network compared to T. spicata. The four most abundant genera found (higher than 10%) were Glomus, Gigaspora, Acaulospora, and Scutellospora, with Glomus being the most abundant in both plants. Nonetheless, Gigaspora, Diversispora, and Ambispora were found only in the rhizosphere of N. variegata, whilst Scutellospora, Paraglomus, and Archaeospora were exclusive to the rhizosphere of T. spicata. Therefore, the community of arbuscular mycorrhizal fungi of the rhizosphere of each plant encompasses a unique composition, structure and modularity, which can differentially assist them in the hostile environment. |

| Conteúdo: | Abstract: An oil palm (Elaeis guineensis Jacq.) bud rod disorder of unknown etiology, named Fatal Yellowing (FY) disease, is regarded as one of the top constraints with respect to the growth of the palm oil industry in Brazil. FY etiology has been a challenge embraced by several research groups in plant pathology throughout the last 50 years in Brazil, with no success in completing Koch’s postulates. Most recently, the hypothesis of having an abiotic stressor as the initial cause of FY has gained ground, and oxygen deficiency (hypoxia) damaging the root system has become a candidate for stress. Here, a comprehensive, large-scale, single- and multi-omics integration analysis of the metabolome and transcriptome profiles on the leaves of oil palm plants contrasting in terms of FY symptomatology—asymptomatic and symptomatic—and collected in two distinct seasons—dry and rainy—is reported. The changes observed in the physicochemical attributes of the soil and the chemical attributes and metabolome profiles of the leaves did not allow the discrimination of plants which were asymptomatic or symptomatic for this disease, not even in the rainy season, when the soil became waterlogged. However, the multi-omics integration analysis of enzymes and metabolites differentially expressed in asymptomatic and/or symptomatic plants in the rainy season compared to the dry season allowed the identification of the metabolic pathways most affected by the changes in the environment, opening an opportunity for additional characterization of the role of hypoxia in FY symptom intensification. Finally, the initial analysis of a set of 56 proteins/genes differentially expressed in symptomatic plants compared to the asymptomatic ones, independent of the season, has presented pieces of evidence suggesting that breaks in the non-host resistance to non-adapted pathogens and the basal immunity to adapted pathogens, caused by the anaerobic conditions experienced by the plants, might be linked to the onset of this disease. This set of genes might offer the opportunity to develop biomarkers for selecting oil palm plants resistant to this disease and to help pave the way to employing strategies to keep the safety barriers raised and strong. |

| Conteúdo: | Abstract: Glyphosate-resistant palmer amaranth, Amaranthus palmeri, a difficult to control weed with aggressive growth, capable of causing large yield losses in annual crops, was identified in Brazil, in the state of Mato Grosso, in 2015. After notification, an epidemiological survey was carried out to identify the place of entry and area of dispersion. Containment and eradication measures were quickly established by state and federal phytosanitary authorities through legislative measures. After identification, it was classified as a quarantine weed under official control. The Palmer amaranth Containment and Eradication Committee was established in order to support the phytosanitary defense agencies in the actions to combat the weed. State agricultural inspectors were trained to identify the species and survey the State. Actions aimed at the farmers were also carried out, highlighting the importance of identification, control and awareness. The weed was found in six municipalities in 10 farms in Mato Grosso. The importation of a used cotton harvester from the United States of America and its internal transit were found to be the main route of entry and spread of the weed. The weed spread to the State of Mato Grosso do Sul, in 2022 and was detected in two municipalities and six properties. A detailed survey is on progress. It is necessary to understand movement routes and establish measures to contain it. Effective measures regarding the importation and cleaning of used machinery needs to be adopted to avoid weed seed dispersal, and Federal legislation is needed to contain and eradicate the weed. |

| Conteúdo: | Abstract: The succession of soybean/maize has been largely adopted. Storm damage and crop problems can lead to grain loss, generating maize ear fragments or even whole ears that remain in the soil and still display germination viability, resulting in the occurrence of volunteer plants. In this context, the present study aimed to evaluate the interference of voluntary maize plants on soybean and investigate the susceptibility of maize hybrids to pre-emergence herbicides. In the first step, an experiment was performed evaluating the influence of voluntary maize plant density and spatial distribution on soybean. The experiment was performed in a randomized completely block design (RCBD) with four replications, with treatments disposed in factorial arrangement (2 x 4) + 1. The first factor corresponded to the spatial distribution of maize plants: row or in between soybean rows; while the second factor adopted four infestation densities of maize plants m-2: 4, 8, 12, and 16. The additional treatment consisted of a control without maize plants. For the second step, an experiment was conducted in two locations aiming to determine the efficacy of pre-emergence herbicides in the control of voluntary maize. Both experiments were installed in RCBD in a split-plot scheme with four replications. Fomesafen, lactofen, sulfentrazone, chlorimuron-ethyl, diclosulam, flumetsulam, imazethapyr, clomazone, metribuzin, [sulfentrazone + diuron], [imazethapyr + flumioxazin], and a control without herbicide application were evaluated in the main plot. In each subplot, the maize hybrids DKB310 PRO3? and DKB390 PRO3? were evaluated. No influence on the position of voluntary maize on the soybean yield was observed. The presence of the maize population led to a progressive decrease in soybean yield, ranging up to 86%, at 16 plants m-2. DKB390 displayed a stand reduction of 82.88% after the use of diclosulam. Diclosulam led to better results regarding maize plant decreases for both hybrids. |

| Conteúdo: | Abstract: Sugarcane cultivation uses many chemical inputs to ensure good yields, which puts local water resources under pressure. Grey water footprint (GWF) is a widely used indicator of the volume needed to assimilate a pollutant load in a water body. However, the GWF relies on leaching runoff fractions, which are empirically determined. We hypothesize that these fractions might not represent the true magnitude of the Brazilian sugarcane environment and that management practices can further reduce this fraction loaded into the environment. In two field trials, we measure the herbicides and nitrate loaded into the environment through in situ measurements, determine their loss fractions, compare them with some empirical models, calculate the GWF, and estimate the potential for nitrate pollution attenuation with the adoption of split and incorporated nitrogen application. Both hypotheses are confirmed. For nitrate, our results suggest that the leaching runoff fraction used in most GWF studies is overestimated by about two times, impacting the GWF estimation for the Brazilian sugarcane environment. However, the same conclusion was not possible for herbicides due to the low diversity of the analyzed molecules. In addition, the fertilizer management application reduced the nitrate load on the environment, which the GWF did not necessarily detect. |

| Conteúdo: | Abstract: Agricultural intensification practices have been adopted in the Brazilian savanna (Cerrado), mainly in the transition between Cerrado and the Amazon Forest, to increase productivity while reducing pressure for new land clearing. Due to the growing demand for more sustainable practices, more accurate information on geospatial monitoring is required. Remote sensing products and artificial intelligence models for pixel-by-pixel classification have great potential. Therefore, we developed a methodological framework with spectral indices (Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), and Soil-Adjusted Vegetation Index (SAVI)) derived from the Harmonized Landsat Sentinel-2 (HLS) and machine learning algorithms (Random Forest (RF), Artificial Neural Networks (ANNs), and Extreme Gradient Boosting (XGBoost)) to map agricultural intensification considering three hierarchical levels, i.e., temporary crops (level 1), the number of crop cycles (level 2), and the crop types from the second season in double-crop systems (level 3) in the 2021-2022 crop growing season in the municipality of Sorriso, Mato Grosso State, Brazil. All models were statistically similar, with an overall accuracy between 85 and 99%. The NDVI was the most suitable index for discriminating cultures at all hierarchical levels. The RF-NDVI combination mapped best at level 1, while at levels 2 and 3, the best model was XGBoost-NDVI. Our results indicate the great potential of combining HLS data and machine learning to provide accurate geospatial information for decision-makers in monitoring agricultural intensification, with an aim toward the sustainable development of agriculture. |

| Conteúdo: | Abstract: Secondary sexual dimorphism (SSD) in flowering plants is expressed by sexual differences of characters that are not directly related to gamete production. The leaf C/N ratio, photosynthetic traits or clonal responses have never been studied in relation to SSD in yerba-mate. It was hypothesized that leaf and plant photosynthesis are higher in female than in male individuals because females must supply photoassimilates to compensate for the additional reproductive investments of SSD in biomass. Here, we investigated how two contrasting light environments (monoculture—MO and agroforestry—AFS) and plant genders change leaf and plant photosynthesis, plant architecture, leaf and branch biomass production and C and N investments of two male and two female clones. To model the 3D yerba-mate structure, virtual trees were constructed using measurements of plant morphology using VPlant modelling software. The light-response curves of leaf CO2 assimilation were used to model instantaneous leaf and daily plant photosynthesis. Photosynthetic traits derived from light-response curves did not differ between MO and AFS. Some architectural traits were segregated sexually only in MO, while some physiological ones only in AFS. Leaf photosynthesis was higher in females than in males in AFS over a large part of the diurnal cycle, but SSD was not expressed in carbon gains at plant or daily scales. Leaf C/N ratio was higher in MO than in AFS, indicating MO as an ecosystem with higher degree of environmental degradation. Female clones had leaves with lower C/N ratio than males in both systems, relating to higher leaf photosynthesis on an area basis in females. SSD expressed in leaf photosynthesis over a large part of the diurnal cycle in AFS was not observed in carbon gains at plant or daily scales, indicating that the integration of physiology and architecture equalized the gender specificities. The insensitivity of photosynthetic traits derived from light-response curves indicated acclimation of yerba-mate leaves to a wide range of incoming light. |

| Conteúdo: | Abstract: The assessment of soil quality improvement provided by biochars is complex and rarely examined. In this work, soil quality indices (SQIs) were produced to evaluate coffee industry feedstock biochars improvement on soil quality samples of a heavy metal-multicontaminated soil. Therefore, a 90-day incubation experiment was carried out with the following treatments: contaminated soil (CT), contaminated soil with pH raised to 7.0 (CaCO3), contaminated soil + 5% (m/m) coffee ground biochar, and contaminated soil + 5% (m/m) coffee parchment biochar (PCM). After incubation, chemical and biological attributes were analyzed, and the data were subjected to principal component analysis and Pearson correlation to obtain a minimum dataset (MDS), which explain the majority of the variance of the data. The MDS-selected attributes were dehydrogenase and protease activity, exchangeable Ca content, phytoavailable content of Cu, and organic carbon, which composed the SQI. The resulting SQI ranged from 0.50 to 0.56, with the highest SQI obtained for the PCM treatment and the lowest for the CT. The phytoavailable content Cu was the determining factor for differentiating PCM from the other treatments, which was a biochar original attribute and helped to improve soil quality based on the SQI evaluation, further than heavy metal immobilization due to the soil sample pH increase. Longer-term experiments may illustrate clearer advantages of using biochar to improve heavy metal-contaminated soil quality, as physical attributes may also respond, and more significant contributions to biological attributes could be obtained as biochar ages. |

| Conteúdo: | Abstract: The bioactive compounds of Artemisia annua have been used as feed supplements due to their pharmacological activities. The present study examined the effect of short-term feeding with a supplemented diet on the growth, feed efficiency, intestinal morphology, stress, immune system, and antioxidant biomarkers of juvenile Nile tilapia (Oreochromis niloticus) to evaluate the efficacy of using an alcoholic extract of A. annua (ae-Aa) as an additive in fish feed. Juvenile fish (200 fish, 30.43 ± 0.54 g) were distributed in 10 tanks (400 L, 20 fish/tank) corresponding to two treatments, each with five replicates. The fish were fed either a control diet (37% protein, 11% lipid: ae-Aa free) or an equivalent diet containing 0.5% ae-Aa to satiation for 15 days. Subsequently, blood, liver, and intestine samples were obtained from 10 fish per treatment group (2 fish per tank). Dietary supplementation with ae-Aa affected the leukocyte count (27.9 vs. 19.7 × 103 µL−1, ae-Aa group vs. control group), leukocyte respiratory activity (0.3 vs. 0.2 DO), and serum lysozyme concentration (28.1 vs. 22.4 ng dL−1) but not blood cells or the oxygen-carrying capacity. Treatment with ae-Aa reduced the plasma cortisol level (11.0 vs. 15.1 µL−1) but did not affect the levels of either glucose or chloride. Dietary ae-Aa influenced hepatic catalase (453.2 vs. 255.7 µmol H2O2 mg pt−1 min−1), glutathione-S-transferase (406.9 vs. 279.8 nmol mg pt−1 min−1), glutathione (4.5 vs. 2.9 nmol mg pt−1), and superoxide dismutase activity (22.4 vs. 20.1 U mg pt−1) and thus affected the antioxidant capacity, as reflected by reductions in lipid peroxidation (21.3 vs. 34.4 nmol mg pt−1) and DNA damage (26.7 vs. 32.2 µg DNA mg pt−1). Dietary ae-Aa increased the intestinal villus area and improved growth (body mass, 24.2 vs. 20.7 g; body length, 2.0 vs. 1.6 cm). Based on the above-described results, the administration of dietary ae-Aa, even for a short period, may have beneficial effects on immunity and oxidant defences and enhance the growth rate. |

| Conteúdo: | Abstract: Grape juices are rich in bioactive compounds; however, for these compounds to exert their functionality, they must be bioaccessible. Thus, the present study evaluated a simulated digestion process on the main bioactive compounds of monovarietal grape juices of five Brazilian hybrid cultivars (V. vinifera x V. labrusca). Characterization of the chemical profiles in liquid chromatography (HPLC-DAD-RID), behaviour of phenolics in the stages of digestion and bioaccessibility through the INFOGEST protocol plus intestinal barrier passage were carried out. Of the 24 polyphenols identified in the grape juice samples, 11 were bioaccessible, with emphasis on the class of flavanols. Procyanidin B2 (101?426%), (+)-catechin (169?370%) and gallic acid (61?230%) stood out in all juices, showing that these compounds are key to the functionality of these drinks. Particularities were observed to differ between juices, demonstrating that factors such as the cultivar should be explored more extensively in studies on functional foods. The study also suggests that quality components such as sugars and organic acids influence the bioaccessibility of beverages. |

| Conteúdo: | Abstract: Symbiotic interactions between microorganisms and social insects have been described as crucial for the maintenance of these multitrophic systems, as observed for the stingless bee Scaptotrigona depilis and the yeast Zygosaccharomyces sp. SDBC30G1. The larvae of S. depilis ingest fungal filaments of Zygosaccharomyces sp. SDBC30G1 to obtain ergosterol, which is the precursor for the biosynthesis of ecdysteroids that modulate insect metamorphosis. In this work, we find a similar insect-microbe interaction in other species of stingless bees. We analyzed brood cell samples from 19 species of stingless bees collected in Brazil. The osmophilic yeast Zygosaccharomyces spp. was isolated from eight bee species, namely Scaptotrigona bipunctata, S. postica, S. tubiba, Tetragona clavipes, Melipona quadrifasciata, M. fasciculata, M. bicolor, and Partamona helleri. These yeasts form pseudohyphae and also accumulate ergosterol in lipid droplets, similar to the pattern observed for S. depilis. The phylogenetic analyses including various Zygosaccharomyces revealed that strains isolated from the brood cells formed a branch separated from the previously described Zygosaccharomyces species, suggesting that they are new species of this genus and reinforcing the symbiotic interaction with the host insects. |

| Conteúdo: | Abstract: Deforestation accounts for the majority of greenhouse gas emissions in developing countries. In Brazil, deforestation represents ~ 70% of the nation’s greenhouse gas emissions. Among the main deforested vegetation, Cerrado (Brazilian savanna) occupies a prominent position as it is the second biggest biome in Brazil. Despite its importance, there are still few estimates of above and belowground biomass of Cerrado vegetation encompassing its structural and spatial complexity. Also, Cerrado holds a specific biodiversity that is normally undervalued and which is being lost in the fires of agricultural fronts. In this context, this study aimed to verify the relationship of the existing flora biodiversity in a cerrado stricto sensu with its aboveground biomass and carbon stocks. The possibility of a relationship between fine root mass and soil organic carbon content was also verified. The study area presented a total of 67 species and 798 trees (average: 1596 trees ha−1). The mean total aboveground biomass and carbon stocks were 77.08 Mg ha−1 and 38.54 Mg ha−1 respectively. Soil organic carbon stock (0–30 cm) was 8.51 Mg ha−1 whereas fine roots were 1.637 Mg ha−1. Total aboveground biomass presented a highly significant asymptotic relationship with biodiversity demonstrating its importance in reaching high biomass accumulation. A significant relationship between soil organic carbon content and fine root biomass was found making easier belowground biomass estimates. |

| Conteúdo: | Abstract: Secondary sexual dimorphism (SSD) in flowering plants is expressed as differences in sexual characteristics that are not directly related to gamete production, involving a wide variety of morphological and physiological traits. Yerba mate (Ilex paraguariensis) is an evergreen dioecious tree native to South America. It was hypothesized that: (1) in early years, the two yerba-mate genders would segregate with lower frequency in biomass production than during later years; (2) in the case of SSD, higher biomass production would be seen for female plants when compared to male plants at a more advanced age; (3) higher SSD would appear in morphotypes that represent leaf adaptations to full sunlight cultivation; and (4) progenies originated from provenances from higher altitudes will show greater SSD in biomass production. One experiment with 135 progenies originated from six provenances with different altitudes was established in 1997 in a monoculture (under full sunlight conditions). Biomass production (leaves and thin twigs) per plant was evaluated during four harvests (1999, 2001, 2003, and 2015). The frequency of SSD in biomass production did not change throughout the plant?s life. Males were more productive than females in 1999, 2001, and 2003, while the increased frequency of more productive female plants was observed during the most recent harvest (2015), resulting in an equal frequency of female and male progenies. Sexual segregation was observed in dully green, sassafras, and gray morphotypes that are characterized by their waxy leaf structures, an adaptation to elevated irradiance and UV. As a result of adaptative responses to stressful conditions and elevated interplant variability, the relationship between SSD and biomass production of progenies originated from the highest altitudes segregated with higher frequency when compared to the lowest altitudes. |

| Conteúdo: | Abstract: One factor limiting the achievement of high yields in the soybean crop is weed interference. The level of weed interference can vary according to the specificities of the weed community but also due to the agronomic characteristics of the soybean varieties. The objective of this work was to evaluate the effects of weed interference on soybean varieties of different relative maturity groups (RMG). A field experiment was implemented in a randomized complete block design, in a 3 × 4 factorial scheme, with five replications. The treatments were composed of the varieties BMX Flecha® (RMG 6.6), BMX Power® (RMG 7.3), and BMX Bônus® (RMG 7.9), associated with the following four weed managements: weeding throughout the cycle; weeded up to 20 days after emergence (DAE); weeded after 20 DAE until the end of soybean cycle; not weeded throughout the entire cycle. There was no interaction between the effects of the varieties and the weed management for emergence speed index, plant height, chlorophyll, first pod height insertion, plant population, thousand-grain weight and yield. The initial weed management caused changes in the composition of the weed community. The managements weeded throughout the cycle and weeded up until 20 DAE provided higher levels of chlorophyll and grain yield. The management without weeding during the entire cycle negatively influenced yield components. Late interventions in weed control, regardless of the soybean variety, result in yield losses. |

| Conteúdo: | Abstract: Water availability, light, management practices, and harvest time impacts on Coffea arabica L. yield and bean quality remain uncertain. It was hypothesized that the soil water and light availability could impact berry distribution, yield, and bean chemical attributes within the plant canopy. Therefore, it was aimed to study berry yield, berry distribution, and bean chemical traits along the canopy strata of four coffee genotypes (Iapar 59, Catuaí 99 and two Ethiopian wild accessions, ‘E083’ and ‘E027’), cultivated with (IRR) and without irrigation (NI) in the two initial harvest years. The maximum height of berry occurrence was lower in NI than in IRR plants in both harvest years. In the 2nd harvest year, higher leaf-to-fruit ratio was found under NI than under IRR for all genotypes, except for Catuaí 99, while the most regular berry distribution among canopy strata was obtained in IRR ‘E083’, the highest bean yield in IRR ‘E083’ and Iapar 59, and the highest percent of useful bean biomass in NI Catuaí 99. The reduced lipid content under IRR was more important in the 1st (all genotypes) than in the 2nd harvest year (Iapar 59 and ‘E027’). As a novelty, chemical bean composition was additionally impacted by light availability along the canopy strata. Proteins declined from bottom (shaded) to upper (highly light exposed) strata, regardless of genotype and harvest year. Similar stratification was observed in caffeine in the 2nd year. Although some traits were somewhat changed among strata, no substantial quality changes occurred, thus allowing that harvest might include the entire plant and not only some specific strata. Iapar 59 and ‘E083’ showed chemical composition usually associated with high bean quality, with the highest lipid, sucrose, and soluble sugar contents, and the lowest caffeine, chlorogenic acids, and phenolic components among four genotypes, but Iapar 59 plants were less affected in their yield under NI. Based on additional responses from space occupation and yield only under IRR, the wild accession ‘E083’ must be considered in future breeding programs as promising material for intensive input conditions. High bean quality and the less variated yield under lower soil water availability qualified the Iapar 59 as the most prominent among the four genotypes. |

| Conteúdo: | Abstract: Climate change impacts are stressing many economic sectors worldwide, including agriculture, increasingly hindering efforts to meet human needs. Dioxide carbon is one of the main greenhouse gases and it affects directly the crop production. The objective of this study was to evaluate if established remote sensing indices could detect the effects of elevated atmospheric CO2 on the leaves of coffee (Coffea arabica L.) plantation growing under field conditions. Plots of coffee plants were exposed to ambient air (~390 µmol CO2 mol-1) and elevated CO2 (~550 µmol CO2 mol-1) at the free air CO2 enrichment (FACE) experiment. The statistical design was the completely randomized blocks with six replicates per treatment (ambient CO2 and elevated CO2), with 10m-diameter plots. Coffee leaves were spectrally characterized by reflectance spectra on their adaxial surfaces and seven vegetation indices were calculated from reflectance data: chlorophyll normalized difference index (Chl NDI), normalized difference nitrogen index (NDNI), normalized difference vegetation index (NDVI), photochemical reflectance index (PRI), pigment specific simple ration indices for chlorophyll a (PSSRa) and chlorophyll b (PSSRb), and structural independent pigment index (SIPI). NDNI was a sensitive indicator of the atmospheric CO2 effects on coffee leaves. NDVI, PSSRa and PSSRb were sensitive to estimate the effect of elevated CO2 only under drought conditions. These indices identify the effect of CO2 when a long period with high precipitation deficit stressing the leaves occurred. Chl NDI, PRI and SIPI were not sensitive to atmospheric CO2. |

| Conteúdo: | Abstract: Farmers in the Brazilian Cerrado are increasing grain production by cultivating second crops during the same crop growing season. The release of PlanetScope (PS) satellite images represents an innovative opportunity to monitor double cropping production. In this study, we analyzed the potential of six PS monthly mosaics from the 2021/2022 crop growing season to discriminate double cropping areas in the municipality of Goiatuba, Goiás State, Brazil. The four multispectral bands of the PS images were converted into normalized difference vegetation index (NDVI), enhanced vegetation index (EVI), green-red normalized difference index (GRNDI), and textural features derived from the gray-level co-occurrence matrix (GLCM). The ten most important combinations of these attributes were used to map double cropping systems and other land use and land cover classes (cultivated pasture, sugarcane, and native vegetation) of the municipality through the Random Forest classifier. Training and validation samples were obtained from field campaigns conducted in October 2021 and April 2022. PS mosaic from February 2022 was the most relevant data. The overall accuracy and Kappa index of the final map were 92.2% and 0.892, respectively, with an accuracy confidence of 81%. This approach can be expanded for mapping and monitoring other agricultural frontiers in the Cerrado biome. |

| Conteúdo: | Abstract: The SAFER (Simple Algorithm for Evapotranspiration Retrieving) algorithm and the radiation use efficiency (RUE) model were coupled to test large-scale remote sensing environmental indicators in Brazilian biomes. MODIS MOD13Q1 reflectance product and gridded weather data for the year 2016 were used to demonstrate the suitability of the algorithm to monitor the dynamics of environmental remote sensing indicators along a year in the Brazilian biomes, Amazon, Caatinga, Cerrado, Pantanal, Atlantic Forest, and Pampa. Significant spatial and temporal variations in precipitation (P), actual evapotranspiration (ET), and biomass production (BIO) yielded differences on water balance (WB = P−ET) and water productivity (WP = ET/BIO). The highest WB and WP differences were detected in the wettest biomes, Amazon, Atlantic Forest, and Pampa, when compared with the driest biome, Caatinga. Rainfall distribution along the year affected the magnitude of the evaporative fraction (ETf), i.e., the ET to reference evapotranspiration (ET0) ratio. However, there was a gap between ETf and WB, which may be related to the time needed for recovering good soil moisture conditions after rainfalls. For some biomes, BIO related most to the levels of absorbed photosynthetically active radiation (Amazon and Atlantic Forest), while for others, BIO followed most the soil moisture levels, depicted by ETf (Caatinga, Cerrado, Pantanal, and Pampa). The large-scale modeling showed suitability for monitoring the water and vegetation conditions, making way to detect anomalies for specific periods along the year by using historical images and weather data, with strong potential to support public policies for management and conservation of natural resources and with possibilities for replication of the methods in other countries. |

| Conteúdo: | Resumo: Devido ao aumento do consumo de agrotóxicos, a contaminação de águas superficiais por esses produtos tem sido constantemente estudada. O foco desta pesquisa foi avaliar o destino ambiental da atrazina, herbicida muito utilizado em cultivos de cana-de-açúcar e mostrar como a aplicação manual pode influenciar na distribuição da atrazina ao longo de uma área de plantação e também nas suas perdas. Além disso, antes do planejamento experimental, buscou-se entender a relação entre dados empíricos locais e as causas macro para o aumento do uso de produtos químicos na agricultura, contextualizando o uso de atrazina no Brasil e no Estado de São Paulo. Em seguida, o experimento foi realizado em parcelas experimentais, pois estas são preferíveis quando se objetiva a obtenção de dados primários. As análises físico-químicas realizadas em conjunto com análises geoestatísticas mostraram que a forma de aplicação causou um grande desvio padrão na distribuição do produto ao longo da área de cultivo. Em relação à perda do produto, o fator que mais influenciou foi a intensidade da geração de escoamento superficial em cada parcela experimental. |

We used a randomized block experimental design in a 3 × 4 × 2 factorial scheme: row spacing of 40, 80, and 120 cm; populations of 25,000, 43,750, 62,500, and 81,250 plants·ha-1; and Fort cultivars (semi-erect leaves, and early cycle) and DKB 950 (erect leaves and super-early cycle). Three field trials were conducted in the state of São Paulo, Brazil, from mid-March. The spacing reduction provided antagonistic effects on yield with different response from hybrids in the most of locations. Population density increased plant height, stalk lodging and grain yield; populations ≥ 68,000 plants per hectare provided the best yields. Specific determinations were made in the area where moderate frost occurred; higher leaf area index and less Brix in the stem at 40 cm spacing were obtained, but without any increase in plant dry mass and grain yield. The hybrid with erect leaves was more adapted to the reduced spacing and exhibited less leaf damage by frost. The effect of frost was greater at reduced row spacings; therefore, this factor should be considered when selecting the population arrangement of off-season corn in areas with frequent frost. |

| Conteúdo: | Abstract: The current scenario of Agroforestry Systems (AFS) worldwide lacks specific machinery, resulting in practically all operations being carried out manually. This leads to a significant physical effort for small-scale farmers and limits the implementation of AFS to small areas. The objective of the study was to evaluate the suitability of existing machines for performing agroforestry tasks. This research utilizes Descriptive Statistics and Exponentially Weighted Moving Average methods to evaluate the data and compare the treatments, where different machines are used to cut Mombaça grass (Megathyrsus maximus Jacq): (i) costal brushcutter (CBC); (ii) tractor-mounted rotary brushcutter (RBC); and (iii) mini grain reaper machine (GRM). The experiments were conducted in Jaguariúna, São Paulo, Brazil. GRM is recommended for achieving greater biomass production, reducing raking time, and minimizing operational costs. CBC is suitable for smaller areas due to its affordability and slow operation, which requires significant physical effort. RBC is recommended for reducing working time, physical effort, and personnel costs, making it suitable for larger-scale contexts. |

| Conteúdo: | Abstract: This work brings a refined estimation of the land use change and derived CO2 emissions associated with sugarcane cultivation, including changes in management practices and refined land-use carbon stocks, over the last two decades for Brazil?s center?south and north regions. The analysis was carried out at the rural property level, considering spatially explicit land conversion data. With the refinements, we found a net carbon removal of 9.8 TgCO2∙yr−1 in sugarcane cultivation areas in the 2000?2020 period, which was due to the expansion of sugarcane over poor quality pastures (55% of the gross removals), croplands (15%) and mosaic (14%) areas, and the transition from the conventional burned harvesting to unburned (16%). Moreover, 98.4% of expansion was over existent agricultural areas. Considering all the land use changes within sugarcane-producing rural properties, the net removal is even larger, of 17 TgCO2∙yr−1, which is due to vegetation recovery. This suggests that public policies and private control mechanisms might have been effective not only to control deforestation but also to induce carbon removals associated with sugarcane cultivation. These results indicate sugarcane production system and derived products as contributors to net carbon removals in the land sector in Brazil and should be considered for both bioenergy and agricultural sustainability evaluation. |

| Conteúdo: | Abstract: Plants can recognize pathogen-derived molecules and trigger systemic acquired resistance. In plant pathogenic bacteria, several of these elicitors are structural components constitutively present in the pathogen, such as cell wall lipopolysaccharide (LPS). This research aims at evaluating the ability of crude LPS from incompatible Xanthomonas strains to control tomato bacterial spot caused by X. euvesicatoria pv. perforans. Crude LPS from strains that demonstrated the ability to be recognized by tomato plants were evaluated through spray, leaf infiltration, and soil applications. The LPS from X. axonopodis pv. passiflorae strain CMAA 1829 was tested three times, showing a greater reduction both in the number of lesions per leaflet and in disease severity when applied on soil. However, chlorophyll content in tomato leaflets presented a brief reduction in the short term. Peroxidase (PO) and polyphenoloxidase activities in plants exposed to crude LPS from CMAA 1829 increased in the first day after pathogen inoculation (DAI), but only PO activity remained high throughout at least the 15 DAI. Results show that the use of crude LPS from host-incompatible strains of Xanthomonas to trigger systemic resistance can configure a valuable asset to control tomato bacterial spot. |

| Conteúdo: | Abstract: Queens play an essential role in the colonies of stingless bees. Typically, only one queen occurs in a colony at any time, and she dominates the egg laying. Their presence maintains colony cohesion and ensures the development and survivorship of these matriarchal societies. Yet there remain significant gaps in our knowledge of queen life cycles as compared to their daughters, the workers. In this review, we follow chronologically the life of queens from pre-emergence inside brood cells (caste determination), to their interaction with workers (queen selection) and males (sexual selection), and up to adulthood. Stingless bee queens can be determined either trophically or genetically. After emergence, the virgin queens undergo a selection process whereby many are executed by workers. The body size, pheromones, age and behaviour of virgin queens may play a role in queen selection. Queens then leave the nest on a nuptial flight during which they mate just once. After mating, queens are still susceptible to workers? harassment. For example, if they produce diploid males they are killed by workers. Previous studies have successfully in vitro reared and mated virgin queens under laboratory conditions, which have revealed new insights of queen development time, the threshold of minimum and maximum provided food to larvae developing into queens, and lethal and sublethal effects of agrochemical substances. These new techniques have also provided new information about queen physiology. However, the daily routine of queens inside colonies demands further well-designed experiments to capture other patterns of behaviour which remain poorly understood, including their interactions with other queens, workers and even males. |

| Conteúdo: | Abstract: In Brazil, the production of benefcial microorganisms by growers exclusively for their own use is a practice known as “onfarm production”. Regarding on-farm bioinsecticides, they were initially deployed for pests of perennial and semi-perennial crops in the 1970s but, since 2013, their use has extended to pests of annual crops such as maize, cotton, and soybean. Millions of hectares are currently being treated with these on-farm preparations. Local production reduces costs, meets local needs, and reduces inputs of environmentally damaging chemical pesticides, facilitating establishment of more sustainable agroecosystems. Critics argue that without implementation of stringent quality control measures there is the risk that the on-farm preparations: (1) are contaminated with microbes which may include human pathogens or (2) contain very little active ingredient, impacting on feld efcacy. The on-farm fermentation of bacterial insecticides predominates, especially that of Bacillus thuringiensis targeting lepidopteran pests. However, there has been a rapid growth in the past 5 years in the production of entomopathogenic fungi, mostly for the control of sap-sucking insects such as whitefy (Bemisia tabaci (Gennadius)) and the corn leafhopper (Dalbulus maidis (DeLong and Wolcott)). In contrast, on-farm production of insect viruses has seen limited growth. Most of the ca. 5 million rural producers in Brazil own small or medium size properties and, although the vast majority still do not practice on-farm production of biopesticides, the topic has aroused interest among them. Many growers who adopt this practice usually use non-sterile containers as fermenters, resulting in poor-quality preparations, and cases of failure have been reported. On the other hand, some informal reports suggest on-farm preparations may be efcacious even when contaminated, what could be explained, at least partially, by the insecticidal secondary metabolites secreted by the pool of microorganisms in the liquid culture media. Indeed, there is insufcient information on efcacy and mode of action of these microbial biopesticides. It is usually the large farms, some with>20,000 ha of continuous cultivated lands, that produce biopesticides with low levels of contamination, as many of them possess advanced production facilities and have access to specialized knowledge and trained staf. Uptake of on-farm biopesticides is expected to continue but the rate of adoption will depend on factors such as the selection of safe, virulent microbial strains and implementation of sound quality control measures (compliance with emerging Brazilian regulations and international standards). The challenges and opportunities of on-farm bioinsecticides are presented and discussed. |

| Conteúdo: | Abstract: In this study, 106 bacterial strains were isolated from rhizosphere of Deschampsia antarctica and used for the screening of potential antimicrobial compounds. Among all the bacterial strains, 61 (57.55%) were classified as Gram-positive, 34 (32.08%) as Gram-negative, and 11 (10.37%) did not grown under the laboratory culture conditions and were not classified. Organic crude extracts were analysed for potential antimicrobial activity and the B-22-EA ethyl acetate extract was the most effective inhibiting 84% of Escherichia coli growth, and Staphylococcus aureus, Pseudomonas aeruginosa and Micrococcus luteus by 31, 17 and 5%, respectively. The B-22-EA extract showed a MIC of 187 µg/mL on Cryptococcus neoformans, and of 438 µg/mL on Trichophyton rubrum. The strain, coded as B22, was classified as Gram-positive and the taxonomic analysis indicated that this strain belongs to the genera Janibacter, with 98.66% of similarity with Janibacter hoylei PVAS-1 and Janibacter limosus DSM 11140; 98.51% with Janibacter cremeus HR08-44, and 98.36% with Janibacter indicus 0704P10-1, Janibacter anophelis H2.16B and Janibacter terrae CS12. The cellular fatty acids (CFA) composition for B22 (Janibacter sp.) was determined by fatty acid methyl esters (FAME) using gas chromatography and compared with those species for which the B22 strain has a high level of similarity. The comparison among the different species from the genus Janibacter shows that there is a difference in their CFA composition and in their optimum temperature for growth, showing the high biodiversity, even for the same species. The data from this study are important and B-22 (Janibacter sp.) is an interesting source of antimicrobial compounds. |

| Conteúdo: | Abstract: ‘Lima’ orange has great economic importance in the Brazilian fresh-fruit market. Significant postharvest losses have occurred mainly caused by Geotrichum citri-aurantii, the causal agent of sour rot. Currently, there is an increasing interest in studying the potential use of alternative post-harvest technologies to agrochemicals. In this study, two technologies were investigated: hot water treatment (HWT) and UV-C radiation applied individually or in combination. The CCD experimental design was used in the hot water experiment aiming to obtain the combination of levels of the factors temperature and exposure time which optimizes the sour rot control. In the HWT experiment, fruits were immersed in hot water at a temperature between 60.3 and 71.7 °C and exposure time between 15 and 49 s. To assess the effect of UV-C radiation on the severity of the disease, the following doses were evaluated: 0 (check); 0.10, 0.5, 1.0, 2.0; 3.0, 4.0 and 5.0 kJ.m−2. The optimal of factor´s levels obtained from the individual evaluation were then tested in combination: HWT at 62 °C for 44 s and UV-C at 4 kJ.m−2. The effects of the treatments on the quality of ‘Lima’ oranges were evaluated by physical–chemical parameters analysis. The HWT at 62 °C for 44 s reduced the severity of the sour rot in ‘Lima’ oranges by about 20 percent. Temperatures above 70 °C did not control the disease and caused scald of the fruit epidermis. UV-C radiation at the dose of 4 kJ.m−2 efficiently controls the disease preserving the fruit quality, presenting a promising alternative to the use of fungicides in postharvest treatment of ‘Lima’ oranges. The treatment with UV-C radiation preserved the firmness of the fruit delaying the senescence process. |

| Conteúdo: | Abstract: A total of 120 Nellore bulls, [initial body weight (BW) = 307 ± 11.6 kg and 12 mo of age] were allocated into 12 collective pens (10 bulls per pen) in a commercial feedlot to evaluate the effects of a specific blend of tannin and saponins on enteric methane (CH4) emissions. The study was a completely randomized design, in which pens were considered the experimental units (N = 6 pens per treatment) and were randomly allocated into one of two treatments: 1) Control (CON), a basal diet with monensin supplementation (25 mg/kg dry matter [DM]; Rumensin, Elanco Animal Health, Greenfield, IN, USA), or 2) Control + a specific blend of tannin and saponins (TAN; 7 g/kg DM; composed of quebracho and chestnut tannin extracts along with carriers from cereals rich in saponins; SilvaFeed BX, Silvateam, San Michele Mondovi, CN, Italy). After the adaptation period (20 d), the experiment was divided into two phases: growing phase (21 to 53 d; total of 33 d) and fattening phase (54 to 139 d; total of 86 d). Enteric methane emissions were estimated using the sulfur hexafluoride (SF6) tracer gas technique. Interactions between treatment and period (growing vs. fattening) were detected for daily CH4 emissions, in which animals fed TAN reduced CH4 emissions by 17.3% during the fattening period compared to bulls fed CON (P = 0.05). In addition, bulls fed TAN had lower CH4 emissions expressed by dry matter intake (DMI) during the fattening period compared to bulls fed CON (P = 0.06). The findings presented herein indicate that a specific blend of tannin and saponins can be used as a strategy to reduce enteric CH4 emissions and its intensity of Nellore bulls finished in feedlot systems under tropical conditions. |

| Conteúdo: | Abstract: The yerba mate leaf metabolic composition depends mainly on genetics, sex, plant and leaf age, light intensity, harvest time, climate, and fertilization. In yerba mate, the secondary sexual dimorphism (SSD), the leaf metabolic SSD association with the frequency of leaf harvests, and the stability of the metabolites in the two genders over the years is not known. It was hypothesized that (1) the SSD in the metabolite segregation would differ among the winter and summer growth pauses, (2) females would show lower metabolite concentrations, and (3) the metabolic concentrations would show stability over the years on the same plants, not obligatorily associated with the SSD stability expression. Variations in theobromine, caffeine, chlorogenic and caffeic acids were correlated to the increasing time since the previous harvest, especially in females. However, the frequency of the metabolic SSD were associated with the studied growth pauses, rejecting the first hypothesis. No regular gender superiority was expressed in the yerba mate leaf secondary metabolites, rejecting our second hypothesis, even though more cases of superior female metabolite accumulation were identified. The stability of the leaf protein was preserved over the four years, with no SSD cases observed. The leaf methylxanthines were time stable, while the decrease in the phenolic content occurred with tree aging, which was not associated with the SSD expression, partially proving our third hypothesis. The novelty was related to the time stability of the leaf metabolic SSD observed over the winter and summer growth pauses, and over the four consecutive years without a regular expression of the male- or female-biased concentrations in the studied metabolites. To demystify the random metabolic gender responses in yerba mate, gender-orientated experiments with a high number of tree repetitions must be conducted, including clonal plants grown in various environments, such as monoculture and agroforestry, or on plantations in different climates and altitudes. |

| Conteúdo: | Abstract: Although insecticides are essential for the effective pest management, the development of sustainable formulations remains a challenge in modern agriculture. This work focuses on the encapsulation of thiamethoxam in polymeric micelles, a nanodelivery system. The nanomicelles, prepared by thin-film hydration method, presented 94.5 ± 10.26% of encapsulation efficiency, average size of 85.14 ± 2.23 nm, zeta potential of −5.3 mV, and acceptable homogenous distribution. Water solubility of thiamethoxam nanomicelles showed an increase by 41.7% in relation of thiamethoxam compound. Toxicity assessment was applied to Raphidocelis subcapitata Korshikov and Artemia salina Linnaeus organisms. The EC50 values obtained for microalgae of polymeric nanomicelles > polymeric nanomicelles loaded thiamethoxam > commercial pesticide. EC50 values obtained for Artemia salina in all treatments could not be compared due to lack of sensitivity shown by this organism to the adopted treatments. Nanoformulation effectiveness was evaluated against D. citri caged in citrus plants grown under greenhouse conditions, in comparison to that of standard formulations. Results have suggested that thiamethoxam nanomicelles might be effective in controlling D. citri around dose 2-fold lower than commercial formulations. |

| Conteúdo: | Abstract: Lethal bronzing (LB) is a fatal infection that affects over 20 species of palms (Arecaceae) and is caused by the phytoplasma ‘Candidatus Phytoplasma aculeata’. This pathogen causes significant economic losses to landscape and nursery companies in Florida, USA. Recently, the vector was determined to be the planthopper Haplaxius crudus, which was more abundant on LB-infected palms. Herein, the volatile chemicals emitted from LB-infected palms were characterized using headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME/GCMS). Infected Sabal palmetto were identified and confirmed as positive for LB via quantitative PCR. Healthy controls of each species were selected for comparison. All infected palms exhibited elevated levels of hexanal and E-2-hexenal. Threatened palms showed high releasing concentrations of 3-hexenal and Z-3-hexen-1-ol. The volatiles characterized herein are common green-leaf volatiles (GLVs) emitted by plants under stress. This study considers the first documented case of GLVs in palms attributed to phytoplasma infection. Due to the apparent attraction of LB-infected palms to the vector, one or several of the GLVs identified in this study could serve as a lure for the vector and supplement management programs. |

| Conteúdo: | Resumo: O objetivo deste estudo foi analisar biomarcadores hematológicos em juvenis de tilápia mantidos em diferentes sistemas experimentais de aquários para monitoramento da qualidade da água e bem estar animal. Foram avaliadas as alterações da série vermelha em juvenis de tilápia provenientes dos grupos controle de dois experimentos conduzidos no Laboratório de Aquicultura e Ecotoxicologia da Embrapa Meio Ambiente, Jaguariúna, SP. Os peixes foram mantidos durante 30 dias em um sistema de aquários com volume útil de 300 L. No experimento 1 utilizaram-se quatro tratamentos e três repetições para avaliação da suplementação alimentar com farinha de minhoca em um sistema de aquários sem recirculação da água. No experimento 2 utilizaram-se quatro tratamentos e cinco repetições para avaliação da inclusão da artemisinina na ração em sistema de aquários com recirculação da água. Apenas os peixes do grupo controle dos dois experimentos foram utilizados para avaliação neste trabalho, sendo que em nenhum desses grupos foram utilizados adição de suplemento ou aditivo na ração. O monitoramento da qualidade da água dos dois experimentos foi realizado diariamente com uma sonda multiparâmetros para as seguintes variáveis: temperatura, pH, oxigênio dissolvido e condutividade elétrica. Não foram observadas diferenças significativas para essas variáveis entre os dois grupos controle, entretanto, a concentração de amônia total foi mais alta no grupo controle do sistema sem recirculação da água. Além disso, observou-se que os peixes mantidos no sistema com recirculação de água apresentaram respostas hematológicas de acordo com o descrito na literatura para tilápias saudáveis e os peixes mantidos no sistema sem recirculação apresentaram valores mais baixos de hemoglobina, hematócrito e eritrócitos. As alterações observadas na série vermelha em juvenis de tilápia sugerem seu potencial como biomarcadores para o monitoramento da qualidade da água e bem estar animal. |

| Conteúdo: | Abstract: The genetic improvement of soybean cultivars over the years has focused on increasing the yield potential and tolerance to some abiotic and biotic factors. However, during the transfer of genes of interest, some genes responsible for a lower tolerance to herbicides can be integrated into the genome of the new cultivar. Thus, the objective of this study was to evaluate the selectivity of herbicide associations applied in the postemergence period of three soybean cultivars. The experiment was conducted in a randomized completely block design, with four replications. The selected cultivars were M7110 IPRO®, Foco IPRO®, and Bônus IPRO®. The herbicides and the respective doses (g a.i. ha-1) used were glyphosate (1176), glyphosate + bentazon (1176 + 600), glyphosate + fomesafen (1176 + 175), glyphosate + lactofen (1176 + 120), glyphosate + imazethapyr (1176 + 100), glyphosate + chlorimuron (1176 + 10), glyphosate + cloransulam (1176 + 39.5), and a control without herbicide application. The visual note of intoxication was evaluated for each treatment. The components of growth and yield evaluated were height, stand, weight of one hundred grains, and yield. The application of postherbicide herbicides did not alter the plant stands of soybean cultivars. Additionally, these herbicides did not reduce the yield of the M7110 IPRO® and Foco IPRO® cultivars. Glyphosate isolated and in association with lactofen or imazethapyr reduced the grain yield of the Bônus IPRO® cultivar. -- Resumen: El mejoramiento genético de los cultivares de soja a lo largo de los años se ha centrado en aumentar la capacidad productiva y la tolerancia a algunos factores abióticos y bióticos. Sin embargo, durante la transferencia de genes de interés, algunos genes responsables de una menor tolerancia a los herbicidas pueden integrarse en el genoma del nuevo cultivar. El objetivo de este estudio fue evaluar la selectividad de las asociaciones de herbicidas aplicadas en la post-emergencia de tres cultivares de soja. El diseño experimental utilizado fue un bloque completamente al azar, con cuatro repeticiones. Los cultivares seleccionados fueron M7110 IPRO®, Foco IPRO® y Bônus IPRO®. Los herbicidas y las respectivas dosis (g a.i. ha-1) utilizados fueron: glyphosate (1176), glyphosate + bentazon (1176 + 600), glyphosate + fomesafen (1176 + 175), glyphosate + lactofen (1176 + 120), glyphosate + imazethapyr (1176 + 100), glyphosate + chlorimuron (1176 + 10), glyphosate + cloransulam (1176 + 39,5), y un control sin aplicación de herbicida. Se hizo una nota visual de intoxicación para cada tratamiento. Los componentes de crecimiento y rendimiento evaluados fueron: altura, rodal, peso de cien granos y rendimiento. La aplicación de herbicidas en post-emergencia no alteró la masa vegetal de los cultivares de soja. Además, estos herbicidas no redujeron el rendimiento de los cultivares M7110 IPRO® y Foco IPRO®. Tanto el glifosato aislado como mezclado con lactofen o imazethapyr redujeron el rendimiento del cultivar Bônus IPRO®. |

| Conteúdo: | Abstract: Physic nut Jatropha curcas cake/meal obtained after oil extraction has a high protein content, however, the presence of antinutrients (trypsin inhibitor, lectin and phytate) and toxic compounds (phorbol esters) limit their use as an alternative feedstuf. Thus, the detoxifcation process in cake/meal is necessary to allow their inclusion in fsh diets. The present study aimed to evaluate the efects of solvent and extrusion-treated jatropha cake (SETJC) in Nile tilapia (Oreochromis niloticus) diets on growth, body composition, nutrient utilization, metabolic and hematological responses, and digestibility of experimental diets. Five experimental diets were formulated to be isonitrogenous (28.50% digestible protein) and isoenergetic (13.39 MJ/ kg digestible energy) with graded levels of SETJC (0, 3, 6, 9, and 12%). The experimental design was completely randomized with fve treatments and four replicates. The detoxifcation treatments reduced the phorbol esters (PE) of jatropha cake by 96% (0.58 mg/g of PE before and 0.023 mg/g of PE after treatments). Increased levels of SETJC depressed growth, feed efciency, and protein digestibility. A similar trend was observed for hematological and biochemistry parameters. Aspartate and alanine aminotransferase, as well as phosphorus and magnesium concentrations in the fllets, increased at the highest levels of SETJC. Thus, the data of the present study suggests that the residual content, diferent structural forms of phorbol ester and its biological activity, as well as some antinutritional factors, can infuence negatively the growth, metabolism and digestibility of experimental diets for Nile tilapia. |

| Conteúdo: | Abstract: Aim: In the present study, the structure of the benthic invertebrates in ponds in the presence and absence of Nile tilapia was evaluated. Methods: The benthic macroinvertebrates and physicochemical parameters were analyzed for a period of eight weeks, every 15 days, in two ponds (one with fish and the other without fish). Benthic invertebrates were sampled with artificial substrate samplers, made with cheap and common materials, like expanded clay, loofah leaves and gravel. Results: With the exception of turbidity, the other physical and chemical variables of water quality were within the ideal limits for tilapia farming. Despite that, there was a significant difference for all physical-chemical parameters monitored, and the average turbidity was much higher in pond with fish. The use of artificial substrate samplers for biomonitoring was effective in the colonization of several taxa in a short period of time (15 days). For benthic community metrics, organism richness, diversity and evenness were significantly higher in the pond without fish. On the other hand, the dominance of Chironomidae and the abundance of Glossiphonidae were much higher in the pond with fish. For Chironomidae, this family was dominant in both treatments, but reached a higher frequency in the pond with fish (98.49%) than in pond without fish (92.87%). The presence of sensitive families, like Leptoceridae (Order Trichoptera), was higher in the pond with no fish, as well as the metric of Ephemeroptera, Plecoptera and Trichoptera families (% EPT). Conclusions: The presence of fish altered the macrobenthic community, since metrics of richness and diversity presented lower values in pond with fish. |

| Conteúdo: | Resumo: Nos pomares brasileiros há pouca diversidade genética de porta-enxertos, deixando o setor citrícola mais suscetível aos fatores bióticos e abióticos adversos, como pragas e doenças e sensibilidade ao déficit hídrico, que reduzem a produtividade e qualidade do fruto. Por isso, são necessários estudos preliminares com novos materiais para o atendimento da demanda do setor na formação de pomares com mudas de qualidade. O presente estudo avaliou o crescimento inicial de 24 Citrandarin (híbridos de Citrus sunki vs. Poncirus trifoliata), em casa de vegetação, no Centro APTA “Sylvio Moreira” por meio de avaliações periódicas do diâmetro do caule (DC) e altura das plantas (AP). Os citrandarins apresentaram o mesmo comportamento de crescimento em relação à AP. Houve o incremento na altura média das plantas com o tempo, tornando-as aptas para o processo de enxertia. Os citrandarins 47, 152, 158, 232 e 304 não apresentaram crescimento do caule no período avaliado. Novos estudos são necessários após a enxertia das principais variedades copa para se verificar a transmissão do vigor, precocidade, compatibilidade e outras características de interesse econômico para a citricultura. |

| Conteúdo: | Resumo: Eucalyptus urophylla is one of the most planted species in the world and in Brazil for presenting excellent productivity, good adaptability to the most varied types of soil and climate and wide application. The experiment was installed in randomized blocks with four replications, linear plots with six plants in a 3 x 2 m spacing. In this test, 21 progenies were selected in three replications, to evaluate the physical (basic density and shrinkage) and mechanical properties (shear, compression, modulus of elasticity and rupture) of the wood. There was no statistical difference between the progenies for the characteristics evaluated because it was juvenile wood. The basic density showed a positive correlation with the radial and volumetric shrinkage and a negative correlation with the shrinkage index. There is no correlation of DBH with the physical or mechanical properties of wood. The values obtained were low but with the potential to increase. |

| Conteúdo: | Abstract: The interrow spacing commonly used in cassava cultivation in Brazil, especially in the Agreste region of Alagoas, ranges from 100 to 120cm. However, the reduction in row spacing can provide agronomic and environmental benefits in cassava cropping systems. Thus, this work aimed to evaluate the performance of two cassava varieties cultivated with reduced interrow spacing. Two experiments were conducted in the field, one in 2015/16 and another in 2017/18. A Split Plot design with four replications was used in both experiments. Four interrow spacing were evaluated in the main plot: 60, 80, 100 and 120cm, with plants spaced 60cm apart within rows, giving populations of 27,778, 20,833, 16,667 and 13,889 plants per hectare, respectively. In the subplots, two cassava varieties were evaluated: Caravela and Pretinha. An increase in interrow spacing promoted a linear reduction in the stem green mass of cassava. Plant height, leaf green mass, main stem diameter, root yield, tuberous root length, tuberous root diameter, flour percentage, flour yield, and starch content were not influenced by changes in interrow spacing. The Pretinha variety was superior to Caravela in the following evaluated traits: stem green mass, the diameter of tuberous roots, root yield, plant height, and flour yield. The results indicate the possibility of altering the interrow spacing in cassava to assist in the cultural management, without impacting crop yield. |

| Conteúdo: | Abstract: The appropriate arrangement of sorghum plants combined with the supply of nutrients increases grain yield. In this context, the objective was to evaluate the agronomic performance of grain sorghum grown under different plant arrangements and nitrogen fertilization levels. Experiments were carried out in Rio Verde and Montividiu in a 3 x 2 factorial randomized completely block design with six replications, with three spacing between rows (reduced, traditional and double row) and the use or not of 90 kg ha-1 topdressing nitrogen. There was a beneficial effect of topdressing nitrogen fertilization on grain yield when sorghum was grown in double rows in both locations, and for the reduced arrangement in Montividiu. However, the effect of topdressing nitrogen fertilization on grain yield in the traditional arrangement was not found. The dry shoot biomass of sorghum plants increased with nitrogen fertilization in Montividiu. The arrangement or topdressing nitrogen fertilization did not influence the thousand-grain weight of Sorghum. |

| Conteúdo: | Abstract: Urea is the main solid N fertilizer used worldwide. Among its advantages are the high nutrient content, ease of handling and application, and low cost. Urea is subject to high losses through NH3 volatilization if surface-applied on soils. Therefore, ammonium nitrate is the preferred N source, especially in the ratoon cycles. Urea treated with the urease inhibitor NBPT and controlled-release fertilizers are options to replace ammonium nitrate. Controlled-release urea (CRU) is produced by coating the urea granules with resin or synthetic polymers so that the urea in the nucleus is not in contact with soil moisture. This study aimed to test CRU in sugarcane ratoons compared with ammonium nitrate (AN) and urea treated with urease inhibitor (UR-NBPT) at three rates: 60, 120 and 180 kg ha-1. Efficiency was also compared with two control treatments, the N control and the NPK control. Two field experiments were established and conducted in 2020 and 2021 in Sao Paulo state, Brazil. Sugarcane yield was evaluated in both experiments. N losses as NH3 volatilized were measured in the first experiment. All sources were equally efficient in promoting increases in sugarcane ratoon yield in both experiments. The relative yield obtained with N fertilizers and the control without N showed yield increases in the first experiment of 40, 54 and 68% for 60, 120 and 180 kg N ha-1 as AN, respectively; 29, 61 and 61% for 60, 120 and 180 kg N ha-1 as urea-NBPT, respectively; and 32, 62 and 67% for 60, 120 and 180 kg N ha-1 as CRU, respectively. Yields were higher in the second experiment, but increases in yield were lower compared to the first. Increases of 7, 10 and 16% for AN in three doses, 5, 12, 15% for UR-NBPT and 7, 9 and 14% for CRU were observed, respectively. N losses as NH3 volatilized were relatively low; CRU fertilizer showed good protection against NH3 losses by volatilization, protecting urea for about 30 days. This protection, however, did not affect yield. NH3 losses reached 13% of the N applied in the treatment with urea (about 16 kg N ha-1), 11% for Urea-NBPT (about 13 kg N ha-1) and 9% for CRU (about 11 kg N ha-1). Analyzing the results of both experiments CRU did not show an advantage in efficiency compared to AN and Urea-NBPT. |

| Conteúdo: | Abstract: The riparian vegetation along water courses and the health of the river’s basin, regarding the aquatic and terrestrial ecosystems associated with them, are widely discussed in literature. However, the maintenance of the services and the conservation role that riparian forests provide to flora and fauna may be affected by the regional matrix that surrounds the water course and by the length and composition of the riparian vegetation associated with them. This study aimed to evaluate the relationships among the grass cover and arboreal species diversity in three watercourses surrounded by a pasture dominated with the alien grass Uroclhoa decumbens (Stapf) R.D. Webster (former Brachiaria decumbens). Two hypotheses were tested: (i) watercourses with larger riparian forest width present higher richness and abundance of native and zoochoric tree species and those associated to late succession stages, and (ii) watercourses with larger riparian forest width present a lower grass cover on their interior. The study was conducted under domain of Semideciduous Seasonal Forest, belonging to the Atlantic Forest biome, municipality of Londrina, Paraná State, south Brazil. The regional climate is Köppen’s Cfa humid subtropical. The soil is classified as a mosaic of eutroferric red nitosols and lithosols. The studied sites mostly comprise pasture with U. decumbens alien grass and small patches of woody vegetation amidst an open pasture dominated by species attributed to the first’s stages of secondary succession. The studied site is immersed in Cambé’s River watershed and contain three watercourses, Cristal River, tributary to São Lourenço River, that, in turn, is tributary to Cambé River. All watercourses are classified as small rivers (Brazilian Forestry Code, federal law: n. 12.651/2012), with length inferior to 10 m between both riversides. The riparian vegetation shares similar characteristics and structure, encompassing woody vegetation with pioneer trees species and high canopy openness. All riparian forests are immersed in pastures with U. decumbens grass. Transects of 200 meters long, measuring one meter wide from the line on both sides of the transect, and one square plot (25 m2) were allocated on the interior of each riparian forest. Transects were evaluated as arboreal species richness and the length of the riparian forest strip. In each plot, the arboreal vegetation was inventoried as species richness, abundance and density, and the U. decumbens cover was measured. The riparian forest width was arranged in two classes, forests with width ≤ 5 m or ≥ 10 m. The studied forests were compared as richness, abundance, density, and grass cover. The correlations among the riparian vegetation with the forest width and grass coverage (%) were evaluated. Species richness, abundance and density did not differ among the watercourses. However, species abundance and density presented positive correlations with the riparian forest width, indicating that the larger is the riparian vegetation, the higher is the species density. Grass cover presents a strong negative correlation with the riparian forest width, indicating that narrow strips of woody vegetation present higher grass cover. A high positive correlation was observed with riparian strip width and native trees, suggesting that native woody species establishment is limited by the riparian strip width and that those rustic trees species are more capable to colonize these environments. Also, the correlation found with species that present abiotic syndromes and pioneer species indicates that trees that can colonize open areas are more suitable to establish on narrow strips of vegetation amidst a pasture. The relationships observed with zoochoric trees suggests that the fauna that visits these forests are tolerant to open areas and visit these areas independently of their vegetation width. The larger riparian forests present lower grass cover and these can be related to shadow micro-sites that reduce the luminosity which can affect the permanence potential of the dominance of U. decumbens. In this way, the data suggests that few plants can establish in these pasture landscape, and those more rustic trees which are able to establish under open areas, high grass cover and canopy openness, and that re-sprout after a fire, became more dominant. For these watercourses, with narrow riparian vegetation strips surrounded by an U. decumbens pasture, the high grass cover can restrict and plant diversity, acting on the course and velocity of secondary succession in these areas. |

| Conteúdo: | Resumo: O Maranhão é um estado detentor de grande potencial hídrico no país, possuindo doze bacias hidrográfi cas. No entanto, essa grande malha hídrica do estado, por si só, não é sufi ciente para garantir o fornecimento de água com qualidade para as diversas necessidades dos maranhenses. Em face das cons-tantes agressões ao meio ambiente, torna-se imperativo ao poder público e à sociedade construírem juntos estruturas de gestão e de controle do uso dos recursos naturais, em particular para os recursos hídricos. Nesse cenário, encontra-se a Bacia do Rio Pindaré, um dos principais afl uentes do Rio Mearim, localizada na porção amazônica do estado do Maranhão, onde existem diversos assentamentos rurais, com atividades agrícolas de subsistência, vivendo sob condições precárias. Nesse ambiente de degradação dos recursos naturais, a água do Rio Pindaré e de seu afl uente Rio da Água Preta se encontra com a qualidade com-prometida, haja vista a presença de compostos de nitrogênio e de fósforo. Assim, o presente trabalho tem como objetivo apresentar alguns cenários de alteração da qualidade da água do Rio Pindaré (trecho Alto Alegre do Pindaré-Tufilândia-Pindaré-Mirim), a partir de dados secundários, complementados por dados primários, estes relacionados ao Rio da Água Preta nos municípios de Zé Doca e Governador Newton Bello, contribuindo assim aos estudos sobre a sustentabilidade dos recursos hídricos na região. |

| Conteúdo: | Abstract: The distinct properties of cocoa beans may be due to their different geographical and genetic origins which lead to chocolates with different characteristics. This study aimed to evaluate dark chocolate samples made with hybrid cocoa cultivated in the Bahia State, Brazil, regarding the composition of bioactive compounds (spectrophotometry, High Performance Liquid Chromatography) and the sensory characteristics (Quantitative Descriptive Analysis-QDA®), and acceptance test). External preference mapping was conducted by first using principal components analysis (PCA) on the QDA data, and then relating consumer preference (overall liking) to this PCA space by regression analysis. Significant differences among the cocoa varieties were found. Chocolate samples that showed lower acceptability also presented higher content of theobromine, caffeine, anthocyanins, and gallic acid which conferred greater intensities of bitterness, astringency, and intense cocoa flavor. Lower levels of methylxanthines, monomeric phenolic compounds, and anthocyanins allowed the highlight of fruity, sweet and caramelized notes, which contributed to greater acceptance of the chocolate samples. Therefore, these characteristics can be recognized as consumer preference drivers (negative and positive, respectively) for the high cocoa chocolates. It seems that higher values of ephicatechin and catechin had no negative contribution to the flavor of the chocolate samples. The findings of this study can be used in agriculture and in the cocoa/chocolate industry, suggesting the potential and applicability of promising hybrid cocoa, with important characteristics, representing a genetic material of great quality, that may be classified as fine flavor cocoa, associating greater value to the product, and contributing to meet consumer needs. |

| Conteúdo: | Abstract: Creamy “requeijão” is the commercially most prominent processed cheese spread in Brazil. The time intensity analysis is important to provide how the flavor behavior is for the consumers during the food ingestion and is used in order to obtain the temporal profile of an attribute in a certain product. In the present study, three different commercial brands, leaders in the market, in their traditional and light versions, were subjected to sensory and instrumental evaluations. Time-intensity analyses and acceptance tests were carried out. After the statistical evaluation, applying ANOVA, the Tukey test (p. 0.05), Partial Least Square (PLS), it was concluded that the consumers preferred products with a more intense cheese flavor and higher adhesiveness, besides expressing a greater acceptance and purchase intention for the product in its traditional version. |

| Conteúdo: | O tomateiro (Solanum lycopersicum) é uma das culturas olerícolas comerciais de maior importância, com destaque dentre as solanáceas cultivadas. Entretanto, muitos problemas fitossanitários incidem na cultura, causando perdas consideráveis. Uma das principais doenças do tomateiro é a mancha bacteriana, que afeta todos os órgãos da parte aérea da planta e, quando em alta severidade, compromete a área fotossintética, além de ocasionar redução da quantidade e qualidade dos frutos. Até o início deste século, a doença era atribuída a dois agentes causais: Xanthomonas vesicatoria e X. axonopodis pv. vesicatoria. Posteriormente, no ano de 2004, por meio de estudos envolvendo ferramentas de biologia molecular se constatou que quatro espécies causavam esta doença, com diferenças epidemiológicas e sintomatológicas sutis entre elas. Embora todas ocorram em tomateiro no Brasil, a espécie X. perforans é considerada prevalente nas principais áreas de produção. |

| Conteúdo: | A mancha bacteriana do tomateiro é uma doença de grande importância em cultivos de tomate de mesa e para processamento industrial no Brasil. É de difícil controle e de ampla ocorrência, já que o patógeno é capaz de ser veiculado por meio de sementes contaminadas. Sua disseminação por aerossóis, período de incubação curto, com rápido progresso em condições favoráveis e habilidade do patógeno em tolerar doses crescentes de cobre, principal elemento utilizado para o seu controle, faz com que danos e perdas significativas sejam relevantes à cultura. Estimativas sobre seu impacto indicam que a incidência pode reduzir em média 41,4% a produtividade de plantas de tomateiro. |

| Conteúdo: | Abstract: Atrazine is a herbicide that has stood out in recent years for being one of the most commercialized pesticides in the country, being used to control weeds, mainly in corn, sugar cane and sorghum plantations. The nanoencapsulation of this compound has been a strategy to combat environmental impacts in agriculture. The objective of this work is to evaluate the effects of nanoatrazine on the growth of bioindicators through trophic transfer, focusing on harmful effects for species present in aquatic environments. The organisms were exposed to the compounds ATZ-NPZ (atrazine encapsulated in zein nanoparticles) and ATZ-PCL (atrazine encapsulated in poly-epsilon-caprolactone nanoparticles), in the presence and absence of organic matter. No significant difference (p>0.05) was observed between treatments and controls, with the exception of ATZ-PCL 0.002 mg/L in the absence of organic matter for Daphnia magna. This microcrustacean showed a significant increase of 31% in the growth rate compared to the control group. Our study shows that there are no adverse effects on the development of bioindicators, as the trophic transfer of these compounds would not pose risks to fish and microcrustaceans. The results indicate positive aspects in the use of nanoatrazine as a viable alternative for agriculture, aiming at a decrease in environmental impacts. |
