| Conteúdo: | Abstract: Biofertilizers that associate biological P-solubilization and plant disease control are sustainable alternatives to mitigate the impact of conventional phosphate fertilizers and agrochemicals in agriculture. However, the economic aspect is critical given that these bio-based products innovate in well-consolidated markets. Thus, we proposed and evaluated, from a techno-economic analysis (TEA) perspective, three different processes for biofertilizer production. The cases differ in terms of downstream processing and the use of single (SM) or double microorganisms (DM), following the concept of a granule bioreactor. In SM cases, Trichoderma asperelloides fungi act as a biocontrol agent, while in the DM case, Aspergillus niger fungi are added to promote P-solubilization. The lowest minimum biofertilizer selling price (MBSP) was US$1.06/kg, attributed to the cases with fewer downstream steps. Moreover, the global sensitivity and uncertainty analyses indicated that the substrate cost and the final product composition significantly impact the MBSP, which fluctuates from US$0.87 to 1.29/kg. These values demonstrate the biofertilizers’ competitiveness since, in addition to promoting soil fertilization, they can help control plant pathogens in a sustainable way. |

| Conteúdo: | Abstract: Microbial biodiversity of an environment can contribute to plant growth and increase crop yield. Plant extracts from soybean (Glycine max (L.) Merrill) were investigated on soybean plants grown after inoculation with these extracts. Soil samples were collected from two important Brazilian soybean-growing regions to produce the extracts used in the experiments. The extracts were produced with material collected from aboveground biomass and rhizosphere of soybean plants cultivated in a controlled greenhouse (phase 1). The extracts produced in phase 1 were applied in a sequential experiment (phase 2). Phase 2 was conducted to examine the plant microbiome after the microbial alteration process in the greenhouse through seed inoculation with the extracts produced previously. Samples of aboveground biomass were collected to determine root dry matter and crop yield. Bacterial 16S rRNA sequences were processed to determine the final microbial content of soybean. The inoculated treatments had lower species diversity; however, the phyla Firmicutes and Bacteroidetes were more abundant in the treatments than in the non-inoculated treatment. The soybean plant stem in the inoculated treatment also had a positive response to enrichment of the bacterial classes Betaproteobacteria, Bacilli and Flavobacteria. Inoculation affected the microbial composition of soybean plants. The alteration of microbiome changes revealed differences for crop yield between the inoculated and non-inoculated treatments, with up to 93.5 % higher crop yields per plant according to the extract applied. |

| Conteúdo: | Abstract: This study evaluated the effects of potassium and sodium carbonate and bicarbonate, Bacillus subtilis (Cohn, 1872) QST-713, Bacillus pumilus (Meyer & Gottheil, 1901) QST-2808, and crude and roasted coffee oils on the inhibition of mycelial growth and conidial germination in Botrytis cinerea Pers.: Fr and the colonization of begonia (Begonia elatior Hort. ex Steud) leaf discs by B. cinerea inoculated before, simultaneously and after with these alternative products. The assays were carried out using the Baladin begonia cultivar. The inhibition of B. cinerea mycelial growth and conidial germination was proportional to increases in the concentration of all the products. The inhibition of conidial germination was directly proportional to the concentrations of B. pumilus QST-2808 and B. subtilis QST-713. Coffee oils were less efficient in inhibiting germination than the other products. The crude and roasted coffee oils, potassium and sodium carbonates and bicarbonates, and B. pumilus and B. subtilis sprayed 24 h before, simultaneously, or 24 h after pathogen inoculation inhibited the colonization of begonia leaf discs by B. cinerea. The positive results for the suppression of B. cinerea by the alternative products tested herein merit scrutiny. There is a pressing need to evaluate these products in the management of gray mold, as the severity of this disease is usually high under favorable conditions in greenhouses. |

| Conteúdo: | Abstract: The use of phosphate rocks as low-solubility phosphorus fertilizers has been promoted to reduce the environmental impacts of agriculture, but adequate nutrient uptake by plants depends on solubilization of the rock, driven by soil microorganisms. Here, investigation was made of the microbial solubilization of low-solubility phosphate rocks, together with simultaneous bioprotective action involving the biocontrol of microorganisms. The aim was to enhance function and value by delivering two effects using a single bio-based product, in accordance with the concept of a “bioreactor-in-a-granule” system. A composite structure was developed, based on a starch matrix, comprising a combination of Trichoderma asperelloides, as a biocontrol agent, and Aspergillus niger, as an acidulant. A significant increase of up to 150% in P solubilization was achieved, indicating the positive effect of the microorganism-composite interaction. In vitro assays showed that the ability of T. asperelloides to inhibit Fusarium oxysporum mycelial growth was maintained in the presence of A. niger. Moreover, the estimated cost of the composite granule (0.35 US$/kg of product on a dry basis) revealed competitive. The results indicated that the association of T. asperelloides and A. niger is an effective way to increase nutrient availability and to inhibit plant pathogens, opening up possibilities for the design of multifunctional bio-based fertilizer composites. |

| Conteúdo: | Abstract: Caatinga is the predominant biome in the Brazilian semiarid region. Its vegetation is composed by plants and microorganisms with high tolerance to drought. Microorganisms associated with plants in this biome can develop mechanisms to protect cells from water stress and desiccation. The aim of this study was to identify plant growth-promoting rhizobacteria associated with the drought-tolerant legume Mimosa artemisiana and to examine their effect on the growth of soybean (Glycine max L.) under drought condition (irrigation with 30% of field capacity). Rhizospheric soil was collected along the Caatinga (In the States of Bahia and Pernambuco) at 4 collection points, totaling sixty subsamples. Xerotolerant bacteria with plant growth-promotion characteristics were isolated in a selective culture medium for diazotrophic bacteria. Two strains of the genera Bacillus and one Paenibacillus were promising in in vitro and in vivo tests. Both were able to grow in a medium with low water availability (0.919 Aw) and could produce exopolysaccharides and indole acetic acid (up to 130 µg mL−1). In addition, they produced 1-aminocyclopropane-1-carboxylate (ACC) deaminase and formed biofilms under drought conditions. The inoculation with the isolated strains in the seedling root system mitigated the adverse effects of drought, increasing roots and shoots dry weights of soybean seedlings compared with non-inoculated. |

| Conteúdo: | Abstract: Monitoring the vegetation structure and species composition of forest restoration (FR) in the Brazilian Amazon is critical to ensuring its long-term benefits. Since remotely piloted aircrafts (RPAs) associated with deep learning (DL) are becoming powerful tools for vegetation monitoring, this study aims to use DL to automatically map individual crowns of Vismia (low resilience recovery indicator), Cecropia (fast recovery indicator), and trees in general (this study refers to individual crowns of all trees regardless of species as All Trees). Since All Trees can be accurately mapped, this study also aims to propose a tree crown heterogeneity index (TCHI), which estimates species diversity based on: the heterogeneity attributes/parameters of the RPA image inside the All Trees results; and the Shannon index measured by traditional fieldwork. Regarding the DL methods, this work evaluated the accuracy of the detection of individual objects, the quality of the delineation outlines and the area distribution. Except for Vismia delineation (IoU = 0.2), DL results presented accurate values in general, as F1 and IoU were always greater than 0.7 and 0.55, respectively, while Cecropia presented the most accurate results: F1 = 0.85 and IoU = 0.77. Since All Trees results were accurate, the TCHI was obtained through regression analysis between the canopy height model (CHM) heterogeneity attributes and the field plot data. Although TCHI presented robust parameters, such as p-value < 0.05, its results are considered preliminary because more data are needed to include different FR situations. Thus, the results of this work show that low-cost RPA has great potential for monitoring FR quality in the Amazon, because Vismia, Cecropia, and All Trees can be automatically mapped. Moreover, the TCHI preliminary results showed high potential in estimating species diversity. Future studies must assess domain adaptation methods for the DL results and different FR situations to improve the TCHI range of action. |

| Conteúdo: | Abstract: Bananas are important tropical fruits conventionally cultivated under intensive nitrogen fertilization. A current challenge is to understand the environmental impacts of this crop across the different cultivation stages considering greenhouse gas emissions. Therefore, the present study evaluated whether inorganic fertilization with ammonium sulphate and urea during different planting stages can change soil CO2, CH4 and N2O emissions. The experiment was conducted in 2018 in an Atlantic Forest region of São Paulo State, Brazil. We used the chamber-based methodology for gas sampling in young and established banana plantations and in a forest remnant fragment. Seasonal differences in temperature and rainfall during the sampling period resulted in a larger WFPS during the wet season. The CO2 emissions followed the rainfall variations. CH4 fluxes were mainly resulted of methanotrophy reactions. The maximum and minimum N2O fluxes were 7.38 and −0.93 mg m2 day−1, peaking after nitrogen fertilization. We found that the accumulated N2O fluxes from soil were greater for the two banana plantations than those observed in the forest remnant in dry and wet seasons. The highest N2O peaks were observed in the young banana plantation. CH4 uptake was 92 and 61% less in young and established banana plantations than in the forest remnant, while N2O emissions were 95 and 74% greater in young and established banana plantations than in the forest remnant. Considering the negative effect of N2O emissions, reduced rates of nitrogen application and the adoption of conservation practices should be considered in young banana plantations. |

| Conteúdo: | Abstract: Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long-lived plants requires direct observation over many years and such datasets have rarely been made publicly available. Here we introduce MASTREE+, a data set that collates reproductive time-series data from across the globe and makes these data freely available to the community. MASTREE+ includes 73,828 georeferenced observations of annual reproduction (e.g. seed and fruit counts) in perennial plant populations worldwide. These observations consist of 5971 population-level time-series from 974 species in 66 countries. The mean and median time-series length is 12.4 and 10 years respectively, and the data set includes 1122 series that extend over at least two decades (≥20 years of observations). For a subset of well-studied species, MASTREE+ includes extensive replication of time-series across geographical and climatic gradients. Here we describe the open-access data set, available as a.csv file, and we introduce an associated web-based app for data exploration. MASTREE+ will provide the basis for improved understanding of the response of long-lived plant reproduction to environmental change. Additionally, MASTREE+ will enable investigation of the ecology and evolution of reproductive strategies in perennial plants, and the role of plant reproduction as a driver of ecosystem dynamics. |

| Conteúdo: | Abstract: Protease inhibitors (PIs) are important biotechnological tools of interest in agriculture. Usually they are the first proteins to be activated in plant-induced resistance against pathogens. Therefore, the aim of this study was to characterize a Theobroma cacao trypsin inhibitor called TcTI. The ORF has 740 bp encoding a protein with 219 amino acids, molecular weight of approximately 23 kDa. rTcTI was expressed in the soluble fraction of Escherichia coli strain Rosetta [DE3]. The purified His-Tag rTcTI showed inhibitory activity against commercial porcine trypsin. The kinetic model demonstrated that rTcTI is a competitive inhibitor, with a Ki value of 4.08 × 10-7 mol L-1. The thermostability analysis of rTcTI showed that 100% inhibitory activity was retained up to 60 °C and that at 70-80 °C, inhibitory activity remained above 50%. Circular dichroism analysis indicated that the protein is rich in loop structures and beta-conformations. Furthermore, in vivo assays against Helicoverpa armigera larvae were also performed with rTcTI in 0.1 mg mL-1 spray solutions on leaf surfaces, which reduced larval growth by 70% compared to the control treatment. Trials with cocoa plants infected with Mp showed a greater accumulation of TcTI in resistant varieties of T. cacao, so this regulation may be associated with different isoforms of TcTI. This inhibitor has biochemical characteristics suitable for biotechnological applications as well as in resistance studies of T. cacao and other crops. |

| Conteúdo: | Abstract: Bananas are a worldwide cultivated crop and one of the main agricultural activities in Brazil. The banana orchards cultivated in the region of São Paulo State are under native areas of the Atlantic Forest biome. The Atlantic Forest has suffered agricultural and urban pressure for many years. Banana crops require soil management and superficial vegetation removal in the first cycles. We conducted a study aiming to understand the impact of long-standing banana cultivation in the Atlantic forest region. Soil samples in banana plantations (EBP) and forest remnants (FR) were collected from trenches with 0- to 100-cm layers. The soil bulk density in EBP until 30-cm depth was 12.76% higher than that in FR. Quantifications of macropores and micropores in FR reached values higher than those in EBP. The results showed that carbon stocks decreased from the top to the deeper layers. Thirty years after the conversion, the FR treatment accumulated 28.23% more carbon than EBP. Considering our results, it was evident that changes in physical and chemical properties reflected the negative impacts of the banana plantations, cropped through conventional management, when converted from forest even in regard to a remnant one. These findings, showed for the first time, lead us to understand the soil management of banana plantations, following conventional agriculture systems, as a potential carbon stock reducer and a factor resulting in the loss of soil quality in the region. Additionally, our data can be used by environmentalists and government policymakers to promote environmental sustainability. |

| Conteúdo: | Abstract: The environmental risks of pesticides found in surface waters of an important agricultural basin in Brazil were estimated by adopting two approaches: individual pesticides risk quotients (RQ) and concentration addition model for pesticide mixtures (∑RQs) contained in each water sample. Monitoring was carried out in the Mogi Guaçu River basin, Brazil, from October 2017 to May 2018. Four sampling points were selected in the Mogi Guaçu River and seven in its tributaries A multiresidue method with solid-phase extraction and subsequent analysis by UPLC-ESI-QqQ-MS/MS was developed to quantify 19 pesticides. Herbicides, except for simazine, presented the highest detection frequencies with values above 70%. Tebuthiuron was found in all 55 analyzed samples, presenting the highest concentration (6437 ng L− 1) over the monitoring period. Fungicides and insecticides showed similar detection frequency (DF) values, ranging from 1.8% to 21.8%. Tebuconazole and carbofuran were the fungicides and insecticides most frequently detected, respectively. January 2018 sampling showed the highest total concentration of pesticides, differing from March 2018 and May 2018 (p < 0.05). The MG2 > TMG8 > MG1 > TMG6 sites showed the highest concentration total of pesticides while MG4 > TMG4 > TMG3 (p < 0.05) sites showed the lowest values: MG4 > TMG4 > TMG3 (p < 0.05). Most pesticide occurrences presented no risks to aquatic organisms. Only 19 out of the 175 pesticide occurrences > LOQ presented individual risks to aquatic biota. Contrary to the results obtained by the individual risk assessment, most pesticide mixtures presented risks to aquatic biota. In 36 out of the 55 samples analyzed during monitoring, pesticide mixtures presented risks to aquatic life. |

| Conteúdo: | Abstract: Bioenergy production from sugarcane can be one of the sustainable means of mitigating climate change. This was the central idea of the Conference, “Carbon Balance in the Sugar-Energy Sector,” held in Brazil on September 14, 2021. The various panels showed that sugarcane stakeholders, including scientists, farmers, industrialists, and investors, are committed to making large-scale sugarcane production a key ingredient in the mitigation of climate change. Their strategies include sustainable land use and management practices to increase soil carbon sequestration; the large-scale production of biofuel, bioelectricity and bioproducts; negative emission industrial technologies; industrial waste recycling; and sector-specific policies rewarding farmers with carbon credits for avoided greenhouse gas emissions. Therefore, the sugarcane sector is not only key to promoting the socialeconomic development of Brazil, but also to promoting energy transition, curbing greenhouse gas emissions and consequently, reducing global warming and climate change. |

| Conteúdo: | Abstract: Microbial crop protection products based on Trichoderma have the ability to display multifunctional roles in plant protection, such as pathogen parasitism, enhance nutrient availability and stimulate plant growth, and these traits can be used to enhance the overall agronomic performance of a variety of crops. In the current study, we explored the multifunctional potential of two indigenous Brazilian strains of Trichoderma (T. asperelloides CMAA 1584 and T. lentiforme CMAA 1585) for their capability of controlling Sclerotinia sclerotiorum, a key plant pathogen of cotton, and for their ability of growth promotion in cotton plants (Gossypium hirsutum). Both strains were able to solubilize mineral phosphorus (CaHPO4), to release volatile organic compounds that impaired the mycelial growth of S. sclerotiorum, and to promote the growth of cotton plants under greenhouse conditions. In dual culture, Trichoderma strains reduced the growth rate and the number of sclerotia formed by S. sclerotiorum. By treating sclerotia with conidial suspensions of these Trichoderma strains, a strong inhibition of the myceliogenic germination was observed, as a result of the marked mycoparasitic activity exerted on the sclerotia. The parasitism over S. sclerotiorum was more effective with T. asperelloides CMAA 1584, whilst the biostimulant effects on cotton growth were more pronounced with T. lentiforme CMAA 1585, which also showed a higher capacity of phosphate solubilization. Thus, T. asperelloides CMAA 1584 displays higher efficiency in controlling S. sclerotiorum, while T. lentiforme CMAA 1585 is more suitable as a biostimulant due to its ability to promote growth in cotton plants. Overall, these Trichoderma strains may be used in mixture to provide both pathogen control and promotion of plant growth, and this strategy will support growers in minimizing the use of synthetic fertilizers and fungicides against white mold in cotton crops. |

| Conteúdo: | Abstract: Leaf decomposition is the primary process in release of nutrients in the dynamic mangrove habitat, supporting the ecosystem food webs. On most environments, fungi are an essential part of this process. However, due to the peculiarities of mangrove forests, this group is currently neglected. Thus, this study tests the hypothesis that fungal communities display a specific succession pattern in different mangrove species and this due to differences in their ecological role. A molecular approach was employed to investigate the dynamics of the fungal community during the decomposition of three common plant species (Rhizophora mangle, Laguncularia racemosa, and Avicennia schaueriana) from a mangrove habitat located at the southeast of Brazil. Plant material was the primary driver of fungi communities, but time also was marginally significant for the process, and evident changes in the fungal community during the decomposition process were observed. The five most abundant classes common to all the three plant species were Saccharomycetes, Sordariomycetes, Tremellomycetes, Eurotiomycetes, and Dothideomycetes, all belonging to the Phylum Ascomycota. Microbotryomycetes class were shared only by A. schaueriana and L. racemosa, while Agaricomycetes class were shared by L. racemosa and R. mangle. The class Glomeromycetes were shared by A. schaueriana and R. mangle. The analysis of the core microbiome showed that Saccharomycetes was the most abundant class. In the variable community, Sordariomycetes was the most abundant one, mainly in the Laguncularia racemosa plant. The results presented in this work shows a specialization of the fungal community regarding plant material during litter decomposition which might be related to the different chemical composition and rate of degradation. |

| Conteúdo: | Abstract: Stingless bees are the most species-rich group of eusocial bees and show great diversity in behaviour, ecology, nest architecture, colony size, and worker morphology. How this variation relates to varying selection pressures and constraints is not well understood. Variation can be caused by selection acting on behavioural or morphological traits, both alone and in correlation across traits. Here we tested whether behavioural and morphological traits important for foraging and defence are linked to nest-entrance architecture, an extended phenotype relevant to both foraging and nest defence. Using 23 species we investigated whether eye size, nest entrance size, landing behaviour and foraging method show cross-species correlations. A phylogenetically-controlled comparative analysis revealed that species with relatively smaller eyes build relatively larger entrances, which in turn are associated with faster landing approaches and fewer landing errors by foragers, both of which could reduce predation risk. Concerning foraging, mass-recruiting species have c. 10-times larger entrance holes than species with a solitary foraging strategy. Larger entrances could help species with mass recruitment to rapidly increase forager traffic or mount a strong defensive response when under attack. Our results show that studying correlations among different traits helps understand phenotypic diversity in species rich groups. |

| Conteúdo: | Abstract: Bacillus spp. are widely marketed and used in agricultural systems as antagonists to various phytopathogens, but it can also benefit the plant as plant growth promoters. Therefore, the longer presence of the bacterium in the rhizosphere would result in a prolonged growth-promoting benefit, but little is yet known about its persistence in the rhizosphere after seed coating. The objectives of this study were to evaluate the tomato growth promotion mediated by Bacillus licheniformis FMCH001 and Bacillus subtilis FMCH002 and the survival rate of these bacteria both in shoots and in the rhizosphere. The Bacillus strains used throughout this study were obtained from Quartzo® produced by Chr. Hansen. The application of a mixture of B. subtilis and B. licheniformis (Quartzo®) at concentrations 1 × 108, 1 × 109, and 1 × 1010 CFU mL−1, as well as the application of B. subtilis and B. licheniformis individually at concentration 1 × 108 CFU mL−1, increased fresh and dry masses of shoot and root system, volume of root system, and length of roots of tomato plants when compared to control. Both Bacillus strains produced IAA after 48 h of in vitro. Bacillus colonies obtained from plant sap were morphologically similar to colonies of B. subtilis and B. licheniformis strains and were detected in inoculated on plants and not detected in control ones. A similar pattern was obtained through DNA-based detection (qPCR). Therefore, B. subtilis and B. licheniformis were able to produce auxin, promote tomato growth, and colonize and persist in the rhizosphere. |

| Conteúdo: | Abstract: Methanotrophic bacteria can use methane as sole carbon and energy source. Its importance in the environment is related to the mitigation of methane emissions from soil and water to the atmosphere. Brazilian mangroves are highly productive, have potential to methane production, and it is inferred that methanotrophic community is of great importance for this ecosystem. The scope of this study was to investigate the functional and taxonomic diversity of methanotrophic bacteria present in the anthropogenic impacted sediments from Bertioga´s mangrove (SP, Brazil). Sediment sample was cultivated with methane and the microbiota actively involved in methane oxidation was identified by DNA-based stable isotope probing (DNA-SIP) using methane as a labeled substrate. After 4 days (96 h) of incubation and consumption of 0.7 mmol of methane, the most active microorganisms were related to methanotrophs Methylomonas and Methylobacter as well as to methylotrophic Methylotenera, indicating a possible association of these bacterial groups within a methane-derived food chain in the Bertioga mangrove. The abundance of genera Methylomonas, able to couple methane oxidation to nitrate reduction, may indicate that under low dissolved oxygen tensions, some aerobic methanotrophs could shift to intraerobic methane oxidation to avoid oxygen starvation. |

| Conteúdo: | Abstract: The Neotropical region hosts 4225 freshwater fish species, ranking first among the world’s most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications. |

| Conteúdo: | Abstract: Prediction of crop yield, evapotranspiration, and crop water productivity are essential aspects for water management and the sustainable intensification of agriculture. The goal of this study was to evaluate the Cropping System Model (CSM)-CROPGRO-Soybean model for simulating evapotranspiration and crop water productivity of soybean grown in a tropical environment. Energy balance evapotranspiration was measured daily using a Bowen Ratio Energy Balance (BREB) system for irrigated experiments that were conducted in Piracicaba, SP, Brazil, during the 2016-2017 and 2017-2018 growing seasons. Evapotranspiration was simulated with the CROPGRO-Soybean model using either the Priestley-Taylor or the FAO-56 Penman-Monteith method for potential ET combined with either the Ritchie-Two-Stage or the Suleiman-Ritchie soil water evaporation methods. The model provided good predictions of daily (D-statistic > 0.7) and cumulative evapotranspiration (RMSE ranged from 8 to 64 mm). FAO-56 Penman-Monteith with the Ritchie-Two-Stage method provided a better fit than the Priestley-Taylor with Suleiman-Ritchie when compared with measured data. Simulated crop water productivity agreed well with observed, but with a systematic underprediction (variation between simulated and measured ranged from -2.2 to -16.8 %). Simulation of long-term scenarios was conducted for different tropical environments, i.e., Piracicaba and Teresina, with soil tillage and water management practices. The results demonstrated that the implementation of no-tillage can increase 0.1 kg/m3 (11%) crop water productivity for grain. This study also showed that when irrigation was triggered at more than 60% of available soil water, irrigation did not result in an increase in yield despite an increase in water supply. |

| Conteúdo: | Abstract: Eucalypt is one of the most-planted broadleaf genera around the globe, exhibiting high yield, plasticity and growing capacity on a broad range of environments. The main objective of this study is to present the integration of a specific module for eucalypt short-rotation plantations into ECOSMOS (Ecosystem Model Simulator). Different calibrations and validations, from intensively monitored sites, experimental networks, and plots in commercial stands were performed. We calibrated all ECOSMOS model biophysical and physiological parameters for the Eucalyptus module using three micrometeorological experiments. A generic genotype was calibrated and applied to evaluate the model performance in response to contrasting environments and genotypes, on a dataset from an experimental network with high Genotype x Environment interactions. The model was applied over commercial eucalypt plantations sites, where re-calibration was necessary for four parameters of the ECOSMOS-Eucalyptus module related to leaf carbon allocation and specific leaf area, because of significant differences in genotypes and management among datasets. Results showed the consistency of the biophysical and physiological processes solved by the model, simulated energy and carbon fluxes, soil water dynamics, and growth of different plant components when compared with observations; Nash-Sutcliffe efficiency (NSE) of 0.93, 0.43 and 0.27 for net radiation, net ecosystem exchange and evapotranspiration, respectively were obtained for the validation dataset. The generic genotype calibration varied greatly in simulating the eucalypt stem growth of the 26 locations. The generic calibration can be used as reference for eucalypt plantation’ areas in Brazil; however, a re-calibration is recommended for operational applications to adjust the ECOSMOS-Eucalyptus module to the management conditions, management practices and genotypes used by companies. |

| Conteúdo: | Abstract: Bioenergy from sugarcane production is considered a key mitigation strategy for global warming. Improving its representation in land surface models is importante to further understand the interactions between climate and bioenergy production, supporting accurate climate projections and decision-making. This study aimed to calibrate and evaluate the Joint UK Land Environment Simulator (JULES) for climate impact assessments in sugarcane. A dataset composed of soil moisture, water and carbon fluxes and biomass measurements from field experiments across Brazil was used to calibrate and evaluate JULES-crop and JULES-BE parametrizations. The ability to predict the spatiotemporal variability of sugarcane yields and the impact of climate change was also tested at five Brazilian microregions. Parameters related to sugarcane allometry, crop growth and development were derived and tested for JULES-crop and JULES-BE, together with the response to atmospheric carbon dioxide, temperature and low-water availability (CTW-response). Both parametrizations showed comparable performance to other sugarcane dynamic models, with a root mean squared error of 6.75 and 6.05 t ha−1 for stalk dry matter for JULES-crop and JULES-BE, respectively. The parametrizations were also able to replicate the average yield patterns observed in the five microregions over 30 years when the yield gap factors were taken into account, with the correlation (r) between simulated and observed interanual variability of yields ranging from 0.33 to 0.56. An overall small positive trend was found in future yield projections of sugarcane using the new calibrations, with exception of the Jataí mesoregion which showed a clear negative trend for the SSP5 scenario from the years 2070 to 2100. Our simulations showed that na abrupt negative impact on sugarcane yields is expected if daytime temperatures above 35°C become more frequent. The newly calibrated version of JULES can be applied regionally and globally to help understand the interactions between climate and bioenergy production. |

Results: The prevalence of infection by Bc strains on field-caught C. sordidus ranged from 1.3% to 12.9%. Similar to the Beauveria bassiana strains tested, none of the Bc strains caused more than 50% weevil mortality at a concentration of 1 × 108 conidia ml−1. Bc strain CMAA1810 caused the highest mortality in C. sordidus and had enhanced insecticidal activity when formulated with an emulsifiable oil. In paired co-culture assays, this same strain showed a significant growth-inhibitory effect on the causal agent of Fusarium banana wilt (Fusarium oxysporum f. sp. cubense, Foc) of twofold magnitude compared with the control. Cell-free crude filtrates derived from the red-pigmented culture broth of Bc (CMAA1810) strongly reduced Foc conidial viability, and this inhibitory activity was inversely related to the age of the Bc culture. Crude concentrated filtrates from 4-day-old cultures exhibited the strongest antifungal activity (13-fold) compared with untreated Foc conidia. The abundant compound identified in the crude filtrate of Bc was oosporein (1,4-dibenzoquinone) present at a concentration of 0.829 ± 0.018 mg g−1 dry matter, and the antifungal activity of the filtrate was demonstrated. Conclusion: These results indicated that Bc strains might have the potential to manage both C. sordidus and Foc, two of the major phytosanitary problems in banana crops worldwide. Further research under field conditions using suitable formulations of virulent Bc strains in combination with the metabolite oosporein is needed to evaluate their efficacy in the management of C. sordidus and Foc in banana plantations. |

| Conteúdo: | Abstract: Silver nanoparticles (AgNPs) currently possess widespread applications in many products. Although there is an increase in the evaluation of their potential environmental risks and toxicity, the data available on AgNP safety levels are limited. Studies on the ecotoxicological and environmental risks of AgNPs, then, are still a requirement. In the present study, AgNPs sized at 82.8 nm were synthetized with an aim to assess their effect on some organisms including algae, plants, microcrustaceans, cnidaria, nematodes, aquatic insects, earthworms, and fish embryos. In addition, some ecotoxicity data obtained from the literature were also used. The non-observed-effect concentration (NOEC) was then calculated for each organism using a log-logistic function. Additionally, the stability of AgNPs in contact with the culture media throughout the analyzed period and conditions employed was evaluated in order to ensure their availability for the organisms tested. The AgNPs remained stable, presenting a dispersion rate of less than 20%, except for the A. salina medium, which presented a dispersion of approximately 25% but did not display differences in AgNP size. The predicted no-effect concentration (PNEC) in the aquatic and sediment compartment was estimated to lie in a concentration range from 0.07 to 0.35 µg Lâ??1. A risk quotient (RQ) of 28.6 was derived for the NPs tested in relation to a maximum AgNP predicted environmental concentration (PEC) estimate. Since an RQ value superior to 1 indicates an occurrence of risk and, consequently, the need for management measures to be implemented, the present data, in conjunction with the expected increase in AgNP use, reinforce the importance of the establishment of AgNP safety levels that can contribute to AgNP risk assessment studies. |

| Conteúdo: | Abstract: The objectives of this study were to test an artificial substrate sampler method for aquaculture ponds and assess the water quality based on the benthic macroinvertebrate community living in fishpond sediment at four farms with tilapia production in the Baixa Mogiana region of São Paulo State, Brazil. Benthic macroinvertebrates were monitored every 15 days for 3 months. Approximately 500,000 organisms distributed in 47 taxa were collected. Chironomidae, Glossiphonidae, Hirudinidae, Libelullidae, Oligochaeta, and Polycentropodidae were present in all collected samples, with the dominance of Chironomidae in the benthic community. Polycentropodidae, a sensitive family to organic pollution, had a greater abundance in fish farms with better environmental conditions. Significant differences in dissolved oxygen and pH were observed among fishponds at different fish farms. Biomonitoring with artificial substrate is a simple and low-cost alternative to monitoring water quality of tilapia culture in fishponds. The artificial substrate sampling method was effective, but the evaluation of more critical conditions of water quality would improve the method and enhance the knowledge of taxa and ecology of macrobenthic organisms in fishponds. |

However, studies are required to evaluate the stability of the relationship among DMC x SSC x consumer acceptance for different mango cultivars under different climatic/seasonal growing conditions. The hypothesis of our study was that the minimum mango DMC required to achieve high consumer quality and acceptance is highly affected by the cultivar and climatic/seasonal growing conditions. The objective of this study was to determine the fruit DMC at harvest required to achieve high consumer quality and acceptance for Palmer and Tommy Atkins mangoes produced during the summer and winter growing seasons in the Sao Francisco Valley, Brazil. |

| Conteúdo: | Abstract: The Brazilian Savanna presents a complex agricultural dynamic and cloud cover issues; therefore, there is a need for new strategies for more detailed agricultural monitoring. Using a hierarchical classification system, we explored the Harmonized Landsat Sentinel-2 (HLS) dataset to detect soybean in western Bahia, Brazil. Multispectral bands (MS) and vegetation indices (VIs) from October 2021 to March 2022 were used as variables to feed Random Forest models, and the performances of the complete HLS time-series, HLSS30 (harmonized Sentinel), HLSL30 (harmonized Landsat), and Landsat 8 OLI (L8) were compared. At Level 1 (agricultural areas native vegetation), HLS, HLSS30, and L8 produced identical models using MS + VIs, with 0.959 overall accuracies (OA) and Kappa of 0.917. At Level 2 (annual crops perennial crops pasturelands), HLS and L8 achieved an OA of 0.935 and Kappa > 0.89 using only VIs. At Level 3 (soybean other annual crops), the HLS MS + VIs model achieved the best performance, with OA of 0.913 and Kappa of 0.808. Our results demonstrated the potential of the new HLS dataset for medium-resolution mapping initiatives at the crop level, which can impact decision-making processes involving large-scale soybean production and agricultural sustainability. |

| Conteúdo: | Abstract: Background: We examined the influence of superoxide dismutase 3 (SOD3) Arg213Gly and Peroxisome Proliferator-Activated α-Receptor (PPARα) 7G/C polymorphisms to a single dose of purple grape juice supplementation on time-to-exhaustion running test, redox balance and muscle damage in recreational runners. Methods: Forty-seven male recreational runners performed a running test until exhaustion after supplementation with grape juice or a control drink. Serum total antioxidant capacity (TAC), malondialdehyde (MDA), plasma nitrite (NO), creatine kinase (CK) and lactate dehydrogenase (LDH) were measured pre and post exercise. Also, polymorphisms were analyzed in DNA extracted from the oral mucosa. Results: Grape juice improved the time-to-exhaustion. When analyzed by genotype, the recreational runners with GG+CG genotypes of the SOD3 gene had greater time-to-exhaustion than the CC genotype, but was no different for the PAPRα gene. A slight difference was noted in TAC, since the CC genotype of the SOD3 gene showed higher TAC values in the post-exercise compared to the baseline and with pre-exercise, but these values did not increase compared to the CG+GG group, respectively. The SOD3 and PPARα genes were similar at all times for the other biochemical variables. Conclusion: The ergogenic effect of grape juice was genotype-dependent for SOD3 Arg213Gly. However, biochemical redox balance markers did not explain this difference. |

| Conteúdo: | Abstract: Background: The control of ticks is challenged by the resistance of tick populations to chemical acaricides. In this study, we evaluated, under laboratory conditions, the efficacy of Heterorhabditis bacteriophora against Rhipicephalus (Boophilus) microplus engorged females with varying body weights (150, 200, 250, 300 or 350 mg per female) or from eight different geographical populations. We also determined the efficacy of H. bacteriophora for tick control under field conditions. Results: R. microplus engorged females with varying body weights exposed to 150 juveniles of H. bacteriophora resulted in a high control efficacy (97.5% to 98.4%). Tests with females from different geographical populations comprised eight tick strains treated with H. bacteriophora and their respective control groups. The biological parameters of females exposed to nematode treatments did not differ significantly and resulted in 89% to 99% of control efficacy. Trials conducted under field conditions were performed in field plots with Megathyrsus maximus grass. Treatment groups received eight cadavers of Tenebrio molitor fully colonized with H. bacteriophora at 1 week prior to the release of female ticks, whereas control groups were untreated. On the first day of the experiment, six engorged females were distributed in each plot. On day 42 and day 63, the apical portion of the grasses with R. microplus larvae were collected and quantified. The population of R. microplus larvae was reduced up to 73.1% in plots treated with H. bacteriophora at day 63 after treatment. Conclusion: R. microplus engorged females with varying body weights or from different geographical populations were highly susceptible to H. bacteriophora. The field test demonstrated the efficacy of H. bacteriophora in reducing R. microplus larvae in infested pastures. |

| Conteúdo: | Abstract: Agricultural intensification is often seen as an appropriate approach to meet the growing demand for agricultural products. In regions affected by seasonal or chronic water scarcity, closing the yield gap depends on irrigation. Brazil is the second-largest wheat importer of the world and irrigated wheat has high yield potential in Brazil, especially in tropical and sub-tropical regions of the country. The crop coefficient (Kc) is still a practical and simple way of quantifying crop irrigation requirements. In this paper, we provided Kc values based on a robust experimental dataset across different wheat-producing regions in Brazil. Four experiments were conducted in three sites [season 2017 in Piracicaba, State of São Paulo (Southeast region); season 2012 Maringá, State of Paraná (Southern region); and seasons 2016 and 2017 Rondonópolis, State of Mato Grosso) (Midwest region)] using lysimeters and the Bowen ratio energy balance method for crop evapotranspiration measurements. Our data showed that Kc values varied among the regions analyzed. For the Midwest region, Kc values ranged from 0.88 to 1.36; the Southeastern region from 0.81 to 1.15, and the Southern region from 0.67 to 1.01. Considering values suggested by FAO, those for arid climates should be used in the Midwest region, sub-humid values for the Southeast, and humid values in the Southern. Differently, that was observed for other crops, our database showed wheat Kc values being stable disregarding the ETo range, which might be related to relatively lower ETo during the winter. |

| Conteúdo: | Abstract: Among the prospective biocontrol agents, the saprophytic filamentous fungus Clonostachys rosea is an excellent necrotrophic mycoparasite of numerous plant pathogenic fungi. However, its commercial development has been hampered by mass production difficulties during solid-state fermentation. Conversely, the submerged liquid fermentation shortens the cultivation time while increasing yields of fungal propagules. However, this method has been overlooked for C. rosea. In this work, we investigated the impact of liquid pre-culture inoculum on the spore production by the two-stage fermentation process using rice grains in comparison to the traditional solid-state fermentation. In parallel, we studied the submerged cultivation of C. rosea by manipulating carbon-to-nitrogen (C:N) ratio and nitrogen source, with the further optimization of spore production in a benchtop bioreactor. Additional bioassays included assessing the bioactivity of water-dispersible microgranules (that contained a submerged conidia) against the whitefly (Bemisia tabaci biotype B) and Sclerotinia sclerotiorum (causal agent of the white mold). Our results showed a maximum concentration of 1.1 × 109 conidia/g-dry-matter after 7 days of cultivation by two-stage fermentation process. The liquid fermentation yielded 1.4 × 109 submerged conidia/ml after 7 days using a medium with a 50:1 C:N ratio, and it also induced the production of microsclerotia (MS) up to 1.35 × 104/ml within 6 days with 10:1 C:N ratio; both media were supplemented with dextrose monohydrate and soybean meal. The fermentation batches carried out in a benchtop bioreactor with medium 50:1 C:N ratio and amended with soybean meal rendered a production peak on the fourth day, corresponding to 1.11 × 109 conidia/ml and 4.35 × 108 colony forming units (CFU)/ml. Following air-drying, the conidia production from air-dried microgranules of C. rosea biomass was estimated at 3.4 × 1010 conidia/g of formulated product upon re-hydration for 7 days. Both submerged conidia and MS of C. rosea inhibited 100% germination of S. sclerotiorum sclerotia by direct parasitism. The air-dried submerged conidia exhibited a suppressive activity on sclerotia (88% mycoparasitism) and early whitefly nymphs (76.2% mortality) that rendered LC50 values of 3.2 × 104 CFU/g soil and 1.5 × 107 CFU/ml, respectively. Therefore, the submerged liquid culture of C. rosea may offer a feasible and cost-effective method for its large-scale production, alleviating critical constraints to their commercial use while providing an additional tool for management of B. tabaci and S. sclerotiorum. |

| Conteúdo: | Abstract: The aim of this work is to optimize the nutritional conditions using low-cost carbon and nitrogen sources for microsclerotia (MS) production of two Brazilian Trichoderma asperellum strains (BRM-29576 and BRM-29104). A fractional factorial design was used to investigate five variables: carbon source, carbon concentration, nitrogen source, C:N ratio and fungal strain. In this study, the optimal nutritional conditions for improving MS yield was achieved using sucrose and autolyzed yeast, carbon concentration at 20 g L−1 and C:N ratio of 10:1 for the BRM-29104 strain, which outperformed the other strain and yielded up to 2.5 (±0.9) × 104 MS mL−1 within 7 days of fermentation. Sucrose and autolyzed yeast are two economically available carbon and nitrogen sources in Brazil that are suitable for MS production by T. asperellum BRM-29104. Vacuum filtration of MS biomass through nylon filter (200 mesh/74 μm) increased MS concentration, resulting in up to 1.8 (±0.2) × 105 MS g−1. Our results support a cost-efficient liquid medium to achieve high MS yields by strain BRM-29104 in combination with an easy method to harvest and concentrate MS from culture broth for further formulation development. |

| Conteúdo: | Abstract: Land-use change (LUC) accounted for approximately 66% of CO2 emissions in Brazil in 2020, with significant implications for carbon footprint of Brazilian agricultural products. Accurate LUC estimates associated with agriculture are critical to carbon footprint (CF) and life cycle assessment (LCA) studies and derived measures towards low-carbon supply chains. The aim of the study was to provide direct LUC (dLUC) estimates of CO2 emissions associated with a comprehensive set of agricultural products in Brazil at municipal-level and based on spatially-explicit land conversion data, appropriate for CF and LCA studies. The effect of different dLUC modeling choices on the results are also presented. The modeling followed IPCC guidelines and improved the BRLUC method. MapBiomas spatially-explicit data, municipality-level statistics, regionalized carbon stocks and a shared responsibility approach were combined to obtain dLUC emission rates for 64 crops, plus forestry and planted pastures, in the 5,570 Brazilian municipalities, as well as at state and national levels. It will be open access at www.embrapa.br. The most recent version led to an estimated 911 Mtons of CO2 associated with agriculture in 2019, 81% of that associated with planted pastures. National level dLUC emission rates for corn, pastures, soybean and sugarcane were estimated as 2.0, 4.1, 2.3 and 0.3 tCO2.ha−1.yr−1, respectively. The dLUC emissions are highly heterogeneous across the country and land uses, ranging from positive to negative. In general, they were higher in the Amazon biome, due to deforestation, and lower in Eastern Brazil, where agricultural areas are more consolidated. The resulting data is more consistent with dLUC rationale, IPCC guidelines and PAS2050 when previous land use is known and is recommended to be used, whenever data at farm level are not available. The study also shows the strong effect of different dLUC modeling choices on results and reinforces recommendations for further mitigation options. |

| Conteúdo: | Abstract: In precision agriculture, the adoption of management zones (MZs) is one of the most effective strategies for increasing agricultural efficiency. Currently, MZs in sugarcane pro- duction areas are classified based on conventional soil sampling, which demands a lot of time, labor and financial resources. Remote sensing (RS) combined with vegetation indi- ces (VIs) is a promising alternative to support the traditional classification method, espe- cially because it does not require physical access to the areas of interest, is cost-effective and less labor-intensive, and allows fast and easy coverage of large areas. The objective of this study was to evaluate the ability of the normalized difference vegetation index (NDVI) and the two-band enhanced vegetation index (EVI2) to classify sugarcane MZs, compared with the conventional method, in the Brazilian Cerrado biome (savannah), where about half of Brazil ́s sugarcane production takes place. This study used historical crop produc- tion data from 5,500 production fields in three agricultural years (2015 to 2018) and NDVI and EVI2 values of 14 images acquired by the Landsat 8 satellite from 2015 to 2018 in Google Earth Engine (GEE). Although improvements are still necessary and encouraged, a new methodology of classifying MZs according to VIs was proposed in this study. The NDVI was not correlated with MZs classified using the conventional method, whereas EVI2 was more sensitive to biomass variations between MZs and, therefore, could better discriminate between MZs. The EVI2 values measured in crops aged 180 to 240 days in the rainy season proved to be the best strategy for classifying MZs by RS, where MZ A, for example, had EVI2 of 0.37, compared to MZ E, which had an EVI2 of 0.32. |

| Conteúdo: | Abstract: Purpose: To clarify the concept of the amortization period (20-year factor) associated with direct land-use change (dLUC) accounting, discuss its main inconsistencies, and propose improvements. The current practice is to divide (amortize) the estimated emissions associated with dLUC that has occurred over the last 20 years by another 20 years. Both periods are referred ambiguously as “amortization period.” Issues arise when considering them as a single temporal aspect (TA) that cannot fully represent the complexity of diverse research and policy contexts. Methods: First, a systematic review was conducted to understand the 20-year amortization history and concepts and discuss its inconsistencies. Based on the review results, we propose the adoption of two distinct TAs, decomposed from the “amortization period.” Then, we performed a sensitivity analysis by estimating carbon emissions due to dLUC in six land uses in Brazil: soybean, maize, sugarcane, pasture, planted forest, and mango. Results and discussion: The literature review shows that several strategies have emerged to reduce or avoid adopting the amortization period. However, most of these proposals are based on complex approaches focusing on alternatives associated with the life cycle impact assessment stage. We found that the commonly adopted amortization period has an ambiguous nature that could be explored at the life cycle inventory analysis stage. Thus, we argue that there are two distinct TAs linked to amortization in dLUC: (i) the inventory period adopted to account for land-use changes; and (ii) the period over which carbon emissions are annualized. These temporal aspects were named here the “LUC-inventory period” (IP) and the “LUC-amortization period” (AP), for clarification purposes. The sensitivity analysis showed that different values of IP and AP drastically change the emissions results due to dLUC in Brazil for different crops and land uses. Conclusion: We advocate that the “amortization period” should be decomposed into two TAs: “LUC-inventory period” and the “LUC-amortization period.” They affect how the carbon debt incurred by expanding agricultural land is accounted for and amortized over a given period-of-time. Therefore, to ensure regulatory compliance, we argued that these proposed TAs should be explicitly defined, based on three possibilities, depending on the goal and context of LCA studies, such as (i) fixed values set in standards and norms; (ii) IPCC’s 20-year defaults; and (iii) customized IP and AP values based on the study’s specificities. |

| Conteúdo: | Abstract: This study evaluated the effects of dietary protein levels on growth performance, hematological and biochemical parameters, carcass and fillet yields, somatic indexes, and body chemical composition of pacu juveniles reared in a biofloc system over a 60-day period. Five isoenergetic (13.4 MJ kg−1 DE) experimental diets were formulated with increasing crude protein (CP) levels (194, 232, 278, 316, and 359 g kg−1). Three hundred fish weighing an average of 3.16 ± 0.3 g were randomly distributed in 20 experimental tanks (50 L) at the rate of 15 fish per replicate and fed experimental diets until apparent satiation four times a day. The experimental design was completely randomized with five treatments and four replicates. Weight gain (WG), thermal growth coefficient (TGC), protein productive value (PPV), and fillet yield (FY) showed quadratic effect (P < 0.05) as protein levels increased. Feed consumption (FC) and carcass yield (CY) showed a linear growth (P < 0.05), while protein efficiency ratio (PER) decreased linearly (P < 0.05) as protein levels increased. The hematological and biochemical parameters did not differ between treatments (P > 0.05), except for the hematocrit. However, blood parameters remained at normal range for this species. The optimal dietary protein level was estimated at 310 g kg−1 CP (≈ 268 g kg−1 DP) for the best growth of pacu juveniles reared in the biofloc system. |

| Conteúdo: | Abstract: There is growing interest in strategies for manipulating the gut microbiota of fish for beneficial communities to increase growth, improve lipid metabolism, stimulate the immune response, and improve the physiological state of the gut. We investigated the effects of diets supplemented with an alcoholic extract of Artemisia annua (ae-Aa) on gastrointestinal (GI) microbiota and intestinal morphology along with its effects on the growth performance of the Nile tilapia (Oreochromis niloticus). Juveniles were fed with ae-Aa supplementation (0.00, 0.10, 0.25, and 0.50% in the diets) for 30 days. The different ae-Aa supply levels affected bacterial interactions, resulting in a more complex network and increasing the proportion of positive correlations between bacterial groups. The different amounts of ae-Aa caused variations in specific bacterial abundance. The phyla Fusobacteriota and Bacteroidota were dominant in the intestinal microbiota in all experimental groups. The abundance of bacteria belonging to Fusobacteriaceae, Stenotrophomonas, and Clostridium correlated positively with protein efficiency, specific growth rate, weight gain, and final weight, while the opposite was observed for Acinetobacter. Diets supplemented with 0.25 and 0.5% of ae-Aa increased (p < 0.05) perimeter, height, and thickness of villi, crypt depth, villus:crypt ratio, and number of goblet cells in the intestine of Nile tilapia compared to control group. Nile tilapia supplemented with ae-Aa at all levels improved growth performance (weight gain, specific growth rate, and protein efficiency rate; p < 0.05) and feed conversion ratio (p < 0.05) compared to the control group. The weight gain was about 21% better in supplemented fish with ae-Aa than unsupplemented ones. The ae-Aa supplementation of Nile tilapia for 30 days modulated the GI microbiota communities providing variations in specific bacterial abundance, affecting the bacterial interactions, resulting in a more complex, stable, and connected network while changing their intestinal morphology and improving the performance of the fish. |

| Conteúdo: | Abstract: Organophosphate insecticides such as dimethoate (DMT) are widely used in agriculture. As a side effect, however, these insecticides contaminate bodies of water, resulting in damage to aquatic organisms. The development of nanopesticides may be an innovative alternative in the control of agricultural pests, increasing effectiveness and reducing their toxicological effects. Based upon this, the present study has investigated encapsulated DMT in alginate chitosan nanoparticles (nanoDMT) and evaluated its toxicological effects on non-target organisms. The nanoparticles were characterized by DLS, NTA and AFM, as well as being evaluated by the release profile. Nanoparticle toxicity was also evaluated in comparison with DMT, empty nanoparticles and DMT (NP + DMT), and commercial formulations (cDMT), in the embryos and larvae of Danio rerio (zebrafish) according to lethality, morphology, and behavior. The nanoparticle control (NP) showed hydrodynamic size values of 283 ± 4 nm, a PDI of 0.5 ± 0.05 and a zeta potential of –31 ± 0.4 mV. For nanoparticles containing dimethoate, the nanoparticles showed 301 ± 7 nm size values, a PDI of 0.45 ± 0.02, a zeta potential of ±27.9 ± 0.2 mV, and an encapsulation of 75 ± 0.32%, with slow-release overtime (52% after 48 h). The AFM images showed that both types of nanoparticles showed spherical morphology. Major toxic effects on embryo larval development were observed in commercial dimethoate exposure followed by the technical pesticide, predominantly in the highest tested concentrations. With regard to the toxic effects of sodium alginate/chitosan, although there was an increase for LC50–96 h concerning the technical dimethoate, the behavior of the larvae was not affected. The data obtained demonstrate that nanoencapsulated dimethoate reduces the toxicity of insecticides on zebrafish larvae, suggesting that nanoencapsulation may be safer for non-target species, by eliminating collateral effects and thus promoting sustainable agriculture. |

| Conteúdo: | Abstract: Actinobacteria have been drawing attention due to their potential for the development of new pest control products. We hereby assess the efects of Streptomyces isolated from marine and caatinga biomes against Duponchelia fovealis Zeller (Lepidoptera: Crambidae), a pest associated with the strawberry culture at a global scale. To this end, eggs deposited by adults were immersed for 5 s in a bacterial suspension, and the larvae were fed on leafets placed in glass tubes containing bacterial suspensions. In both treatments, the control was a saline solution. The bioassays demonstrated that the Streptomyces strains were able to cause the death of D. fovealis eggs (≈ 40%) and larvae (≈ 65%) compared to untreated eggs (1.4%) and larvae (2.0%). The crude extract of strain T49 and the chitinase extract of strain T26 afected larval growth when applied directly to the thorax of frst-instar larvae (larval-adult lifespan of 65.3 ± 0.5 days and 67.5 ± 0.7 days, respectively; survival of 61.2±1.2%) in relation to the control treatment (larval-adult lifespan of 41.75±0.2 days and survival of 83.7±2.6%). The Streptomyces spp. strains T41, T49, and T50 caused antifeeding activity. Apart from larval mortality, the adults that emerged from the larvae exposed to the extracts presented morphological abnormalities, and the moths’ chitin spectra showed clear alterations to the pupa and wings. Our studies show, for the very frst time, that Streptomyces isolated from the marine environment and the Caatinga biome are efective at provoking the mortality of D. fovealis and are promising agents for developing new products with biological control properties. |

| Conteúdo: | Abstract: Rationale: Propolis has a great diversity in its composition due to numerous factors; therefore, each study is an important contribution to the knoFwledge of its composition and biological action. The objective of this study was to determine the chemical profile and biological activity of propolis produced by Scaptotrigona depilis. Methods: Extracts with 70% ethanol (EPE70) and with cereal alcohol (CAPE) were elaborated, and then characterized using UHPLC-ESI(+)-MS/MS. Volatile compounds were extracted and then characterized using gas chromatography mass spectrometry (GC–MS). In addition, antimicrobial activities were verified against resistant strains. Results: The volatile compounds of propolis predominantly consist of sesquiterpenes. Using the exploratory metabolomic approach, compounds of different classes were putatively identified in the ethanolic extracts, of which the most representative were terpenes, and some of the sesquiterpenes identified among the volatiles were also detected. The extracts were shown to be active against Escherichia coli and Staphylococcus aureus bacteria with a minimum inhibitory concentration (MIC) of 0.5 and 1.0 mg mL 1, respectively. Conclusions: The molecular network approach proved to be determining the chemical profile of S. depilis propolis rapidly and accurately, and led to the identification of lipophilic compounds. The identification of compounds using GC–MS and UHPLC-ESI(+)-MS/MS is complementary and useful for the characterization of propolis. |

| Conteúdo: | Abstract: Alternative techniques for applying agricultural products, such as pressurized endotherapy, have shown promise in pest and disease control in coconut palms (Cocos nucifera Linn.). In this work, azadirachtin and abamectin were applied by pressurized endotherapy to control Brassolis sophorae. Twelve different treatments were carried out, and in all of them, at least one plant had the larvae completely dead four and five days after endotherapeutic applications, and all the others died within the next few hours. Leaf and fruit analyses were performed to determine the concentration over time. High concentrations of abamectin were observed after 15 and 30 days on leaves when applied in larger volumes. In fruits, no residue was found regardless of the applied concentration. Analytical methods were developed and validated for leaves and fruits to analyze insecticide residues using LC-MS/MS and modified QuEChERS acetate according to SANTE/11813/2017 guidelines. The insecticide translocation tests in the leaves and the high mortality of insects showed that pressurized endotherapy is a technique to be considered for future studies in controlling B. sophorae in coconut palm trees. |

| Conteúdo: | Abstract: The objective of this study was to investigate the influence of timing of paddock allocation (AM or PM) in tropical grass on nutritive value of the herbage, dry matter intake (DMI), milk yield and composition, ruminal fermentation, nitrogen excretion, and enteric CH4 emissions of dairy cows. Twenty cows were grouped in pairs and randomly distributed within pair to one of two treatments. PM herbage had greater contents of dry matter (DM), soluble carbohydrates, starch, and nonfibrous carbohydrate to protein ratio and lower contents of neutral detergent fiber and acid detergent fiber. There was no treatment effect on DMI, N excretion, milk yield, and CH4 emissions. However, milk protein and casein yields tended to be greater for PM than AM, while milk urea nitrogen concentration was lower for PM than AM. The increase in nutritive value of the afternoon relative to the morning herbage within the framework of this study was not large enough to increase DMI and milk yield or to decrease CH4 emission intensity by the dairy cows as hypothesized. The findings indicate that PM treatment can be a simple and useful grazing strategy that results in an herbage harvest with greater nutritional value and in lower excretion of urea N into milk. |

| Conteúdo: | Abstract: Edible insects are a potential alternative food source of high feed conversion efficiency and protein content. Zophobas atratus is an edible insect that adapts to different diets, enabling sustainable rearing by adding value to by-products and agro-industrial residues. This study aimed to evaluate the performance and nutritional characterization of Zophobas atratus larvae fed with different proportions of grape residue. Physicochemical analysis of the diets and larvae (AOAC procedures), fatty acid profile (chromatographic techniques), metals and non-metals (inductively coupled plasma optical emission spectrometry), larval mass gain, feed conversion efficiency, and mortality rate were assessed. The replacement of 25% of the conventional diet with grape residue increased lipid, ash, and fiber contents and reduced protein, carbohydrates, and energy. It promoted greater mass gain, lower mortality rate, and reduced larval growth time by 51%. Among the replacements, 25% resulted in the second-highest content of calcium, sodium, magnesium, and zinc, and the lowest content of potassium and phosphorus in the larvae. The 100% replacement resulted in the highest amounts of C18:2n6 (27.8%), C18:3n3 (2.2%), and PUFA (30.0%). Replacing 25% of the conventional diet with grape residue is equivalent to the conventional diet in many aspects and improves several larvae performance indices and nutritional values. |

| Conteúdo: | Abstract: Since studies on the reproductive consequences after the exposure to environmentally relevant doses of Benzo(a)pyrene (BaP) during critical stages of development are scarce, this study evaluated female reproductive parameters of adult rats exposed to a low dose of BaP during the juvenile phase. Female rats (Post-natal 21) were treated with BaP (0 or 0.1 µg/kg/day; gavage) for 21 consecutive days. During the treatment, no clinical signs of toxicity were observed. Nevertheless, the ages of vaginal opening and first estrus were anticipated by the BaP-exposure. At the sexual maturity, the juvenile exposure compromised the sexual behavior, as well as the placental efficiency, follicle stimulating hormone levels, placenta histological analysis, and ovarian follicle count. A decrease in erythrocyte, platelet, and lymphocyte counts also was observed in the exposed-females. Moreover, the dose of BaP used in this study was not able to produce estrogenic activity in vivo. These data showed that juvenile BaP-exposure, at environmentally relevant dose, compromised the female reproductive system, possibly by an endocrine deregulation; however, this requires further investigation. |

| Conteúdo: | Abstract: The modernization of computational resources and application of artificial intelligence algorithms have led to advancements in studies regarding the evapotranspiration of crops by remote sensing. Therefore, this research proposed the application of machine learning algorithms to estimate the ETrF (Evapotranspiration Fraction) of sugar can crop using the METRIC (Mapping Evapotranspiration at High Resolution with Internalized Calibration) model with data from the Sentinel-2 satellites constellation. In order to achieve this goal, images from the MSI sensor (MultiSpectral Instrument) from the Sentinel-2 and the OLI (Operational Land Imager) and TIRS (Thermal Infrared Sensor) sensors from the Landsat-8 were acquired nearly at the same time between the years 2018 and 2020 for sugar cane crops. Images from OLI and TIR sensors were intended to calculate ETrF through METRIC (target variable), while for the MSI sensor images, the explanatory variables were extracted in two approaches, using 10 m (approach 1) and 20 m (approach 2) spatial resolution. The results showed that the algorithms were able to identify patterns in the MSI sensor data to predict the ETrF of the METRIC model. For approach 1, the best predictions were XgbLinear (R2 = 0.80; RMSE = 0.15) and XgbTree (R2 = 0.80; RMSE = 0.15). For approach 2, the algorithm that demonstrated superiority was the XgbLinear (R2 = 0.91; RMSE = 0.10), respectively. Thus, it became evident that machine learning algorithms, when applied to the MSI sensor, were able to estimate the ETrF in a simpler way than the one that involves energy balance with the thermal band used in the METRIC model. |

| Conteúdo: | Abstract: Brazil has a large share of hydropower in its electricity matrix. Since hydropower depends on water availability, it is particularly vulnerable to drought events, making the Brazilian electricity matrix vulnerable to climate change. Starting in 2005, Brazil opened the matrix to new renewable sources, including sugarcane-based electricity. Sugarcane is known for its resilience to short dry spells. Over the last decades, its production area moved from the coastal plains of the Atlantic Forest biome to the savannahs of the Cerrado biome, which is characterised by a five- to six month-long dry season. The sugarcane-based electricity system is highly dynamic and complex due to the interlinkages, dependencies, and cascading impacts between its agricultural and industrial subsystems. This paper applies the risk framework proposed by the IPCC to assess climate-change-driven drought risks to sugarcane electricity generation systems to identify their strengths and weaknesses, considering the system dynamics and linkages. Our methodology aims to understand and characterize drought in the agriculture as well as industrial subsystems and offers a specific understanding of the system by using indicators tailored to sugarcane-based electricity generation. Our results underline the relevance of actions at different levels of management. Initiatives, such as regional weather forecasts specifically for agriculture, and measures to increase industrial water-use efficiency were identified to be essential to reduce the drought risk. Actions from farmers and mill owners, supported and guided by the government at different levels, have the potential to increase the resilience of the system. For example, the implementation of small dams was identified by local actors as a promising intervention to adapt to the long dry seasons; however, they need to be implemented based on a proper technical assessment in order to locate these dams in suitable places. Moreover, the results show that creating and maintaining small water reservoirs to enable the adoption of deficit-controlled irrigation technology contribute to reducing the overall drought risk of the sugarcane-based electricity generation system. |

| Conteúdo: | Abstract: The therapeutic efficacy of different doses of albendazole (ABZ) in the treatment of infection by acanthocephalan (Neoechinorhynchus buttnerae) in tambaqui (Colossoma macropomum) was evaluated. The bioaccumulation of ABZ and its main metabolites in the target tissue (muscle plus skin in natural proportions) was also evaluated. The fish received a daily dose of 10, 20 or 30 mg ABZ kg−1 bw via medicated feed for 34 days. Incorporation of ABZ in the fish feed was performed by coating with ethyl cellulose (EC) (0.75% w/w). The quantitation of ABZ residues and its metabolites in the target tissue was done using a validated ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) analytical method. In relation with the therapeutic efficacy, no statistically difference was found between the treated groups. The total residue (sum of ABZ residues and its metabolites) in the target tissue at steady-state was significantly higher for the high dose. Biomagnification factors in all treatments were of low values, indicating that ABZ and its metabolites do not offer the risk of bioaccumulation in the target tissue. Thus, ABZ dose of 10 mg kg−1 bw is recommend. However, the effect of feed coating on treatment effectiveness and bioaccumulation of albendazole relative to an uncoated feed, and joint therapeutic studies of ABZ with anthelmintic natural products are recommended to be conducted. |

| Conteúdo: | Abstract: Drought is considered as the major environmental stress affecting coffee production, and high phosphorus (P) supply may alleviate the drought effects on crop metabolism. Here, we hypothesized that high P supply would mitigate the impacts of drought on Arabica coffee physiology, morphology, and biomass accumulation. Potted Arabica coffee plants were grown under two P levels: the recommended P fertilization (P), and twice the recommended fertilization (+P), and two water regimes: well-watered and water withholding for 32 days. Leaf, stem, and root P concentrations were increased under +P, with plants showing higher photosynthesis and growth than the ones receiving the recommended P dose. Higher plant growth under high P supply seems to upregulate leaf photosynthesis through the source–sink relationship. Under the water deficit, the reduction of leaf photosynthesis, stomatal conductance, transpiration, water use efficiency, carboxylation efficiency, chlorophyll content, number of plagiotropic branches, plant leaf area, and vegetative biomass production was similar comparing plants fertilized with the recommended P to those supplied with +P. However, Arabica coffee trees under high P supply and water deficit presented morphological and physiological traits similar to plants under well-watered and recommended P fertilization. |

| Conteúdo: | Abstract: Earth’s climate has undergone changes in recent decades as a result of the intensification of anthropic activities, which alter the concentration of certain environmental components, such as the atmospheric carbon dioxide (CO2). The present study aimed to evaluate the effect of increasing atmospheric CO2 concentration on plant growth, as well as on the incidence of coffee leaf rust (Hemileia vastatrix) and leaf miner (Leucoptera coffeella) in coffee trees (Coffea arabica) cultivated for three years in a free air carbon dioxide enrichment (FACE) facility. The experiment was conducted at ClimapestFACE facility which was controlled and monitored through a wireless sensor network and established at Embrapa Environment. The CO2 injection was performed until a concentration of 200 μmol mol−1 above the current concentration was reached in the center of the plots. The control plots were kept under current ambient CO2 concentration. The evaluations of plant height and diameter, number of leaves per branch, and incidence of coffee leaf rust and leaf miner were carried out in 2013, 2014, and 2015. Growth of coffee plants (total number of leaves per branch, height and diameter of the stem) was higher under elevated CO2 concentration when compared to the ambient CO2 concentration. The incidence of leaf minor was lower under elevated CO2 concentration when compared to the ambient CO2 concentration. No difference was observed in the incidence of coffee leaf rust between the two conditions considered. |

| Conteúdo: | Abstract: To find effective silver nanoparticles (AgNPs) for control of phytopathogens, in this study, two strains of actinomycetes isolated from the soil of the Brazilian biome Caatinga (Caat5–35) and from mangrove sediment (Canv1–58) were utilized. The strains were identified by using the 16S rRNA gene sequencing as Streptomyces sp., related to Streptomyces mimosus species. The obtained AgNPs were coded as AgNPs 35 and AgNPs58 and characterized by size and morphology using dynamic light scattering, zeta potential, transmission electron microscopy, and Fourier transformed infrared (FTIR). The antifungal activity of the AgNPs35 and AgNPs58 was evaluated in vitro by the minimal inhibitory concentration (MIC) assay on the phytopathogens, Alternaria solani, Alternaria alternata, and Colletotrichum gloeosporioides. The phytotoxic effect was evaluated by the germination rate and seedling growth of rice (Oryza sativa). AgNPs35 and AgNPs58 showed surface plasmon resonance and average sizes of 30 and 60 nm, respectively. Both AgNPs presented spherical shape and the FTIR analysis confirmed the presence of functional groups such as free amines and hydroxyls of biomolecules bounded to the external layer of the nanoparticles. Both AgNPs inhibited the growth of the three phytopathogens tested, and A. alternate was the most sensible (MIC ≤ 4 µM). Moreover, the AgNPs35 and AgNPs58 did not induce phytotoxic effects on the germination and development of rice seedlings. In conclusion, these AgNPs are promising candidates to biocontrol of these phytopathogens without endangering rice plants. |

| Conteúdo: | Abstract: This study presents a literature review of the main advances that took place in the last 10 years in the agricultural production of sugarcane in Brazil, which can effectively result in increased productivity and sustainability. This became a central topic as much of this crop in Brazilian is used to produce ethanol to replace fossil fuels; therefore, the increased concerns about global warming and climate change, and the greater pressure from society for sustainability in agriculture in general became more relevant for sugarcane. Actions have been taken to encourage the use of more conservationist practices from planting to harvesting, greater recycling of residues, preservation of biodiversity, delivery of environmental services, adoption of circular economy and, especially, compliance with internal and external commitments on reduction of greenhouse gas (GHG) emissions, among other aspects. Fertilizer recommendations have been revised to increase yields and ratoon longevity, leading to higher rates of micronutrients and the more frequent application of lime, phosphogypsum, and P fertilizers in ratoons. Optimized use of vinasse includes addition of mineral fertilizers to save field operations for separate fertilization. The sugarcane breeding programs in Brazil are releasing an average of eight varieties per year, including transgenic varieties. Replanting of sugarcane fields with newer and more productive varieties are facilitated by novel planting methods using pre-sprouted settlings (PSS) combined with the nurseries mingled into the crop renewal fields, locally termed “MEIOSI,” which also allow the easy introduction of rotation crops. Soil compaction and ratoon trampling caused by heavy machines that replaced manual harvesting are being solved with GPS-based traffic control, which is embedded in most farming equipment in the sugarcane sector nowadays. Finally, public policies, such as the Renovabio legislation, incentivizing the production of sugarcane/ethanol with low GHG emissions are also in place. With this, the sugarcane industry is revising all field and industrial procedures to optimize operations and earn more decarbonization credits, in a win–win situation. The combined efforts of research institutions and the private sector, along with the proper policies, have the potential to lead toward a renewed and more sustainable sugarcane industry. |

| Conteúdo: | Abstract: Aim of study: To present a mathematical model to simulate the translocation of pesticides injected into coconut trees. Pesticide residues in water and coconut pulp were also evaluated. Area of study: The data were obtained in coconut plants of the Itaporanga Experimental Field, located in the Municipality of Itaporanga d’Ajuda, Sergipe State, Brazil.. Material and methods: To estimate the effect of pesticide site-sap coefficients and retardation factors on translocation and its phytosanitary behavior and risk of contamination of coconut fruits, the stipe was modeled by a classic dispersion-advection equation. The pesticides cyproconazole, azoxystrobin, dimethoate, imidacloprid, metalaxyl, and thiamethoxam were injected into the coconut palm stipe. The method used to extract pesticide residues from pulp, water and coconut sap samples was based on the QuEChERS methodology with modifications. Main results: Simulations showed that (i) the pesticides dimethoate, metalaxyl, and thiamethoxan were the active ingredients showing the greatest potential for translocation in the sap of the coconut tree stem; (ii) the pesticides imidacloprid and metalaxyl translocated upward in the stipe, and more rapidly than pesticides abamectin and cyproconazole, which moved slower to the aerial part of coconut plants. In chromatography analysis, no pesticide residues were quantified in water and coconut fruit pulp samples of coconut trees injected with pesticides, after the evaluated intervals. Research highlights: The proposed model allowed us to observe that the translocation is inversely proportional to the sorption of the pesticide in the stem of coconut trees. |

| Conteúdo: | Abstract: Green mould, caused by Penicillium digitatum, is the major postharvest disease of citrus in all producing countries. The control of this disease is carried out by fungicides in postharvest treatments, which can leave toxic residues in fruits. Therefore, the interest in cleaner technologies and alternatives to the use of fungicides, such as biopesticides, has grown in recent years. Conyza canadensis, an herbaceous weed spread all over the world, contains compounds which have significant activity against P. digitatum. Thus, the present research aimed to evaluate (4Z)-lachnophyllum lactone (LACH), isolated from C. canadensis, in combination with hot water brushing (HWB) and UV-C treatments, to control green mould and to preserve the quality of the fruit. LACH efficiently controlled green mould in orange cv. Valencia. The level of control improved from 24% to 42% according to the dose of LACH adopted, ranging from 10 to 100 µg ml−1 respectively. When in combination with HWB or UV-C, the efficiency of the control was enhanced from 50% to 78% with the lowest dose of LACH (10 µg ml−1) and UV-C at 1.5 kJ m−2, which showed no significant difference when the highest dose of LACH (100 µg ml−1) was applied alone. This treatment delayed the onset of the disease symptoms. A biofungicide based on C. canadensis combined with UV-C and HWB is a potential natural control of green mould. |

| Conteúdo: | Abstract: A variety of plant protein sources have been evaluated in aquafeeds. Crambe meal (CM) has potential for inclusion in fish diets because of its nutritional composition. This study evaluated the apparent digestibility coefficient (ADC) of crambe meal and its potential to partially replace soybean meal (SM) protein in Nile tilapia Oreochromis niloticus diets. The ADC for dry matter, crude protein, ether extract, energy, amino acids, calcium and phosphorus of CM were assessed in fish (n = 80; 65.30 ± 5.32 g). Subsequently, an 80-day feeding trial was conducted with Nile tilapia (n = 140; 6.04 ± 0.25 g) randomly distributed in 20 experimental cages (70 L; seven fish cage-1) allocated in five circular tanks (1000 L) in a recirculation water system, to evaluate the effects of replacement of SM by CM (0, 6, 12, 18 and 24% in isonitrogenous and isoenergetic diets) on growth, blood parameters, fillet yield and proximal composition. The CM shows good digestibility of protein (0.824) and amino acids (0.844) by Nile tilapia and its inclusion in the diet does not affect carcass and fillet yield or proximal composition. Fish fed diets with 24.0% of the SM replaced by CM showed the worst weight gain and feed conversion rate. The protein efficiency ratio decreased in fish fed diets with 12.0, 18.0 and 24.0% of the SM replaced by CM. Hemoglobin, mean corpuscular hemoglobin concentration, total plasma protein, glucose and alanine aminotransferase enzyme activity trend to increase at highest levels of CM in the diet. In conclusion, CM has high digestibility of protein and amino acids for Nile tilapia. However, anti-nutritional factors present in untreated CM interfere on the growth and nutrient utilization of Nile tilapia. |

| Conteúdo: | Abstract: Plant diseases can negatively impact the production and sale of agricultural crops in a given region. Because it is a border state, Roraima is a potential entry route of quarantine pathogens that can threaten Brazilian agriculture. Constant health surveillance is an essential tool to mitigate the risks of the introduction and spread of important pathogens. In order to avoid or reduce the negative impacts caused by diseases resulting from the introduction or occurrence of a pathogen, a well-structured phytosanitary inspection program and technical guidelines for producers are necessary. The combined efforts of research institutions and state agencies aim to reduce production losses caused by diseases. Thus, the objective of this review is to address the main threats and challenges in controlling quarantine pests in the state of Roraima based on the experience of research and extension institutions in monitoring, pest detection and mitigation strategies. In this respect, contextualizing the events discussed may contribute to guiding plant defense measures, thus mitigating the risks of quarantine pathogen introduction and spread in Roraima.
Resumo: A ocorrência de doenças de plantas em cultivos agrícolas pode impactar negativamente a produção e comercialização de produtos agrícolas de uma região. Roraima, por ser um estado fronteiriço, é vulnerável a ser via de ingresso de patógenos quarentenários que podem ameaçar a agricultura nacional. A constante vigilância sanitária é uma ferramenta essencial para mitigar os riscos de introdução e disseminação de patógenos importantes. Para se evitar ou reduzir os impactos negativos causados por doenças, decorrentes da introdução ou ocorrência de um patógeno, é necessário um programa de defesa fitossanitária bem estruturado e orientações técnicas para os produtores. O trabalho conjunto de instituições de pesquisa e de órgãos de extensão visa reduzir as perdas de produção ocasionadas por doenças. Assim, objetiva-se com essa revisão abordar as principais ameaças e desafios no controle de pragas quarentenárias no estado de Roraima com base na experiência das instituições de pesquisa e de extensão no monitoramento, detecção de pragas e nas ações de mitigação. Dessa forma, a contextualização da sucessão dos eventos abordados poderá contribuir para orientar medidas a serem adotadas em defesa vegetal e, por conseguinte, para mitigação de riscos de introdução e dispersão de patógenos quarentenários em Roraima. |

| Conteúdo: | Abstract: Brazil has established itself as one of the world leaders in food production. Different types of remote sensing mapping techniques have been undertaken to support rural planning in the country. However, due to the complex dynamics of Brazilian agriculture, especially in the Cerrado biome (tropical savanna), there is a need for more feasible crop discrimination and monitoring initiatives, which require a consistent time series of remote sensing data at medium meter and potentially up to 3 day Landsat 8 and Sentinel-2 satellite time series, minimizing the cloud cover limitations for rainfed agricultural monitoring. This paper aims to explore the potential of the Harmonized Landsat 8 Sentinel-2 (HLS) data cube to map agricultural landscapes in the Brazilian Cerrado. The HLS multispectral bands from 27 scenes with less than 10% cloud cover, from October 2020 to September 2021, encompassing one entire crop growing season, were processed by the Random Forest algorithm to produce a map with four land use/cover classes (annual crops, sugarcane, renovated sugarcane fields, cultivated pastures, and native Cerrado). We performed accuracy assessment through 10-fold cross-validation and confusion matrix analyses. The results showed a high level of overall accuracy and Kappa coefficient, both with 99%, as well as high user’s and producer’s accuracies of at least 99%. The HLS dataset has been continuously improved, showing very promising results for rainfed agricultural mapping and monitoring. |

| Conteúdo: | Abstract: Riparian area is the last and the best protection that a river can have because it prevents the arrival of physical, chemical, and biological pollutants in the body of water. After a fire in a riparian forest that is in a transition between the seasonal semi-deciduous forest and the savanna, its restoration processes began. The area was taken over by 3 m high colonial grass. Some trees resisted the fire and served as perches for birds. We planted 48 species of 28 families with three basic objectives, fruits for human consumption, shelter and food for fauna and other uses (medicinal and lumber). The cost of implementation was US $ 6,104.21 per hectare. The restoration was good due to the low percentage of failure (33.27%), despite the great drought that occurred at the time of implantation. The average height of the trees was over 2 m at four years. |

| Conteúdo: | Abstract: Fusarium oxysporum f.sp. cubense (Foc), the causal agent of Fusarium wilt of banana (FWB), is doubtless the most challenging pathogen of this crop. In Brazil, FWB caused a dramatic shift from the susceptible cultivars “Maçã” (AAB) and “Prata” (AAB) to Cavendish (AAA) cultivars, which are resistant to local Foc populations. Management practices to reduce yield losses due to FWB in these cultivars would improve returns to growers serving this market, while also building knowledge to cope with other Foc populations, such as tropical race 4, still not present in Brazil. In this study, a set of soil management practices aiming to reduce FWB intensity, enhance soil health, and increase productivity were evaluated in the banana cultivar “Prata Catarina” (Pome, AAB). A field trial was established in a naturally Foc-infested area where three alternative treatments (T1, T2, T3) and a control were compared during three cropping cycles. In the T3 treatment, Ca(NO3)2 and heat-treated rock phosphate were applied as sources of N and P, together with 3 t ha−1 of compost at planting plus 12 t ha−1 of compost per year. T1 and T2 treatments were variations of the T3 treatment. Control plots followed the local practices of the banana growers. Regardless of the treatment, the first symptoms of FWB were observed at the flowering stage. The average FWB incidence was > 90% higher in the control than in the treatments in the first cropping cycle. However, the effectiveness of the treatments on reducing FWB decreased gradually in the second and third cycles. Soil analyses revealed a significant impact in the pH, Ca availability, and base saturation, which were higher in the treatments (T1, T2, T3) than in the control. Plant nutrition was not significantly altered by treatments, except for Ca content, which was lower in the control than in the treatments. The average yield of three cycles was 14% greater in the alternative treatments than in the control. Our results also indicate that the soil management practices tested in this study were not enough to cope with FWB. Further studies testing additional practices, such as reducing initial pathogen inoculum load at pre-planting, early detection, and eradication of infected plants, should also be conducted to verify its applicability as part of integrated FWB management packages. |

| Conteúdo: | Resumo: Os arranjos na cultura da soja podem promover alterações no desenvolvimento das plantas e, consequentemente, na produtividade de grãos. Neste contexto, o arranjo espacial aliado ao hábito de crescimento da cultivar podem ser alternativas para o manejo da cultura da soja para obtenção de maiores produtividades. Dessa forma, o objetivo deste trabalho foi avaliar o desempenho agronômico de um cultivar de hábito de crescimento indeterminado submetido a diferentes espaçamentos entrelinhas e população de plantas em condições de cerrado. O ensaio foi instalado em delineamento de blocos casualizados, em arranjo fatorial 4x4, com quatro repetições, correspondendo a quatro espaçamentos entrelinhas (20; 40; 20/40 e 20/60 cm) associados a quatro populações de plantas (266.667; 400.000; 533.333; e 666.667 plantas ha-1) do cultivar BMX Potência RR®. Os resultados obtidos permitiram constar que os espaçamentos entrelinhas não influenciaram a produtividade bem como de seus componentes. O acréscimo de 66% na população de plantas proporcionou maiores produtividades e massa de mil grãos, massa seca da parte aérea, altura de plantas e de inserção da primeira vagem e redução apenas para o número de vagens na haste principal. |

| Conteúdo: | The Passiflora cincinnata Mast. has high flavor and potential for wine and other alcoholic beverages production. However, for wine production, the presence of pectin becomes undesirable, as it influences the efficiency of the fermentation process and the clarity of the final product. The objective of this study was to optimize the pectin hydrolysis process in Caatinga passion fruit must for wine production with pectinolytic enzymes, using a Central Composite Rotatable Design (CCRD). The 2³ factorial CCRD, E01 to E17 assays, was applied with six axial tests and three replications in the central point. Caatinga passion fruit must was obtained with pulp and distilled water (40:60 proporcion). Commercial enzyme with high concentration of pectinase was tested. Concentration of enzyme (0.014- 0.056 g L-1), working temperature (43-57°C) and reaction time (12-139min) were the independent variables in the optimization process; and the soluble pectin content (mg 100g-1) corresponded to a process-dependent variable. Prior to the beginning of the assays, in order to provide the optimum working pH range for the pectinase, correction of the must pH to 3.9. The initial Caatinga passion fruit wine must had 24.06 mg 100g-1 of soluble pectin in its composition. After the optimization using CCRD, the treatments presented pectin contents ranging from 6.81 (E16: 0.014g L-1/50°C/75min) to 0.00 mg 100 g-1 (E05: 0.05 g L-1/45°C/ 30min and E06: 0.05 g L-1/45°C/120min). According to the results, to a satisfactory process of pectin hydrolysis in Caatinga passion fruit wine must be added 0.05 g L-1 of pectinase at 45°C for 30min. |

| Conteúdo: | Abstract: Jabuticaba is a Brazilian berry known for its therapeutic potential against cancer, obesity, insulin resistance (IR), and others. It is a natural source of bioactive compounds, leading to better glucose metabolism, and attenuating obesity and IR through the reduction of pro-inflammatory status. The present study aimed to observe the prebiotic effect of freeze-dried jabuticaba peel (J) consumption on gut bacteria profile and describe its effects on IR derived from the lipopolysaccharides/Toll-like receptor-4 inflammatory pathway. Jabuticaba peel was chemically characterized, and its bioactive compounds were quantified. Twenty-four C57BL/6 mice were feed with a control diet (n = 6), control diet + J (n = 6), high-fat diet (HF) (n = 6), and HF + J (n = 6) for thirteen weeks. Gut bacteriota (16s RNA sequencing), glucose metabolism (fasting glucose and insulin, OGTT, ITT, HOMA-IR, and β, QUICKI), and inflammatory status (serum lipopolysaccharide, and protein expression) were assessed. The main bioactive compounds found in J were dietary fiber, and anthocyanins, and its consumption along with a healthy diet reduced the abundance of Firmicutes and Actinobacteriota phyla (p < 0.01), increased the Muribaculaceae and Lachnospiraceae families, and Faecalicatena genus (p < 0.05). The correlation test indicates a negative correlation between the Muribaculaceae and glucose metabolism. Jabuticaba peel is a nutritive source of bioactive compounds with prebiotic effects. |

| Conteúdo: | Resumén: Los fitopatógenos y las plagas están entre los primeros indicadores de los efectos del cambio climático por sus características poblacionales y de crecimiento. La roya marrón ( Puccinia melanocephala) es una enfermedad de caña de azúcar ampliamente distribuida a nivel mundial. El objetivo de este trabajo fue evaluar la distribución espacio-temporal de la presencia de la roya marrón de la caña de azúcar en las principales áreas productoras (Tucumán, Salta y Jujuy) de Argentina, como consecuencia del cambio climático. Para ello, se utilizaron dos escenarios climáticos futuros proyectados (A2 y B1) a partir de la base de datos geoespaciales de variables climáticas que provee el IPCC. A2 es un escenario pesimista, mientras que B1 es un escenario más optimista. Los mapas de distribución de condiciones favorables para la enfermedad fueron construidos con una resolución de 0,5º x 0,5º de latitud y longitud. Las condiciones favorables para la infección del patógeno fueron establecidas en base a rangos de temperatura promedio mensual (de 16 a 30°C) y de duración del período de mojado foliar (> 4h/días). Las condiciones de favorabilidad climática para las ocurrencias de la enfermedad se desarrollaron mediante reglas utilizando criterios de lógica matemática de SIG, a partir de la comparación de coincidencia entre un mapa de distribución de condiciones favorables a la enfermedad (construido para el período de referencia 1961- 1990) con la incidencia real de la enfermedad reportada por fitopatólogos de la caña de azúcar. Fueron analizados tres períodos (2011-2040, 2041-2070 y 2071-2100), escenarios A2 y B1. El procesamiento de la información se realizó con el SIG. En el período de referencia las condiciones más favorables ocurrieron en los meses de marzo, abril y mayo. En los escenarios futuros evaluados, en el A2, las condiciones más favorables para la infección deP. melanocephala ocurrió en los meses de abril y mayo para 2011-2040 y en mayo para 2071-2100. Para el escenario B1, se demostró la mayor predisposición en los meses de abril y mayo en ambos períodos. Esta aproximación determinará un leve corrimiento de las condiciones favorables para la infección del patógeno, como consecuencia del incremento de emisión de gases de efecto invernadero, escapando así al periodo de mayor susceptibilidad del cultivo, dado entre febrero y marzo.

The objective of this work was to evaluate the potential risk of the occurrence of orange rust in Argentina and Brazil under the climate change scenarios. A mapping methodology integrated the data of climate projections and the phytosanitary problem supported by Geographic Information System (GIS). Normal climate (1961-1990) and future climate (2011-2040, 2041-2070, and 2071-2100) from Intergovernmental Panel on Climate Change were considered. The conditions of climatic favorability for the occurrence of the disease were established by means mathematical logic criteria of GIS, based on knowledge of the authors, who incorporated the implicit effects of the interaction of the virulent pathogen, susceptible host, and predisposing environmental characteristics. The favorability for the occurrence of sugarcane orange rust in the main sugarcane producing regions of Argentina and Brazil varied over the months considered of the cultivation cycle. For Argentina, the future climate scenarios predicted a reduction in favorability for the occurrence of sugarcane orange rust from December to February and an increase in April. In Brazil, the climatic favorability decreased from December to March and increased in May. |

| Conteúdo: | Abstract: Lippia sidoides Cham. has widespread use in folk medicine because its essential oil (EO) presents great antibacterial properties. In Brazil, this plant has been introduced in governmental programs for herbal medicine, due to its recognized therapeutic activities. This promoted greater interest in the search for new molecules with antimicrobial activity in this EO which have been described by several authors. Thus, this work aimed to present a study of the scientific production of antibacterial activity of the chemical compounds from L. sidoides essential oil (LSEO). The inclusion criteria were articles which assessed the chemical components and antibacterial activity through the inhibition diameter, Minimum Inhibitory Concentration (MIC), and Minimal Bactericidal Concentration (MBC), published between 2000 and 2020. Of the 996 studies identified, 55 met the inclusion criteria. In descending order, the most frequently detected chemical components found in LSEO were: thymol, p-cymene, and caryophillene. Regarding to the origin, the results showed that the extraction of EO were carried out mainly in the Northeast (55.5%) and Southeast (19%) regions of Brazil; and the part of the plant most used for the production were the leaves. In addition, the essential oil showed strong antibacterial activity against most of the bacteria tested.

The paper assessed São Paulo State’s agricultural sustainability by analyzing the current land use adequacy to the land use capability map that follows FAO 1976 “guide for land evaluation” and was applied to São Paulo by the State Agricultural Secretariat. Results indicate inefficiencies in land use at the state level, where more than one-third of agricultural lands do not satisfy technical land capability indications. According to technical land use capability, more than 4.5 million hectares are being underused (economic inefficiency) and another 2.2 million hectares are being overused (environmental inefficiency). Pasturelands represent the most unsustainable land use, where 3.7 million hectares are allocated in high quality lands with high agricultural production potential, and another 0.7 million hectares are allocated in lands with very low quality for agriculture, most of than area degraded. To achieve sustainability, lands with high agricultural production potential should be used to improve agriculture and food production and, on the other hand, lands with very low agricultural production potential should be used for wood production, agroforestry, ecotourism and natural ecosystems conservation. Our results provide a framework for improving land use policies in São Paulo State and highlight an opportunity to achieve land use sustainability. |

| Conteúdo: | Resumo: A biomassa de cana-de-açúcar pode dar importante contribuição ao esforço mundial para a mitigação dos gases de efeito estufa. A cana-energia, um tipo especial, poderia aumentar tal contribuição, pois possibilita maior produtividade e é mais resiliente, ou seja, pode ser cultivada em terras de menor valor agrícola. O presente estudo relata os resultados de terceiro corte de um experimento que teve o objetivo de se determinar as características agronômicas e tecnológicas de um grupo de 14 clones de cana-energia numa condição de solo restritivo, inclusive com ausência de adubação fosfatada no plantio e nenhuma adubação no terceiro corte. O ensaio indicou clones que em 3º corte apresentaram produtividade bastante superior de biomassa verde do que a cana convencional, e especialmente de biomassa seca, mesmo na ausência de adubação fosfatada. Esse resultado ressalta o valor desses materiais numa situação de carência de fertilizantes e preço elevado do mesmo. |

| Conteúdo: | Resumo: O uso do óleo de cravo como anestésico no manejo de peixes e do florfenicol no tratamento de infecções podem deixar resíduos na água, acarretando prejuízos na saúde dos peixes e no meio ambiente. Biomarcadores enzimáticos são alterações nas enzimas detectadas em organismos expostos a substâncias tóxicas na água. A presença de resíduos do óleo de cravo e do florfenicol na água pode interferir nos biomarcadores enzimáticos, prejudicando sua interpretação durante monitoramento da qualidade da água. O objetivo deste estudo foi avaliar o efeito de concentrações residuais do óleo de cravo e do florfenicol na água na resposta dos biomarcadores enzimáticos em tilápias do Nilo. Foram utilizados dois tratamentos com três repetições, considerando cada aquário contendo nove tilápias como unidade amostral. O experimento 1 foi composto pelos tratamentos: óleo de cravo na concentração de 0,5 mg/L com o diluente etanol 96°GL; o segundo tratamento foi acrescido apenas do diluente do óleo, ou seja, etanol a 10µL/L de água e o grupo controle (sem adição de óleo de cravo e sem adição do diluente - etanol) na água. O experimento 2 foi composto pelos tratamentos: 0,0 (grupo controle); 0,5 mg/L e 5 mg/L de florfenicol. Os parâmetros enzimáticos avaliados durante os dois experimentos não apresentaram diferença significativa, indicando que as concentrações residuais de óleo de cravo e do florfenicol avaliados neste estudo não interferem na resposta dos biomarcadores enzimáticos em tilápias. |

| Conteúdo: | Abstract: Earthworm meal comprises a class of food additives with potential to replace or supplement conventional proteins used in fish feed. Considering the potential of earthworm meal, as a protein source for fish feed, this study aimed to investigate the productive performance and the hematological profile of Nile tilapia juveniles fed with a commercial diet enriched with earthworm meal at levels (0.0; 5.0, 10 and 20%). The assay was conducted for 32 days and the productive performance and hematology profile of the animals were evaluated. Tilapia juveniles (n=144; 25.30±3.27g) were distributed in 12 aquariums (300 L) in a static system with partial water changes. The experimental design was completely randomized with four treatments and three replications. There were no significant differences (p>0.05) for performance responses and hematological profile related to variables on hematocrit and CHCM. However, for hemoglobin values the treatment with 20% earthworm meal was similar to the treatments with 5 and 10% earthworm meal, and significantly differed from the control treatment, suggesting its potential as a fish feed supplement. Thus, earthworm meal can be used at 5, 10, and 20% as a supplement for Nile tilapia juveniles without compromising their performance and hematological profile. |

| Conteúdo: | Abstract: Triclosan is a broad-spectrum antimicrobial that has activities against gram positive and gram negative bacteria, fungi and viruses, being used in formulations of personal hygiene products such as toothpastes, shampoos and soaps. Studies demonstrate its presence in urban and industrial effluents and report the detection of residues in surface waters and sediments from freshwater environments. The objective of this study is to evaluate the effect of residual concentrations of triclosan in yellowtail lambaris (Astyanax altiparanae), through the physiological response, such as clinical signs and mortality. Two tests were carried out,the first in concentrations of 5mg/L, 10mg/L, 15mg/L, 25mg/L and two controls. In the second assay, concentrations of 4mg/L, 3mg/L, 2mg/L, 1mg/L, 0.5 mg/L and two controls were used. In both, each fish was considered as a sampling unit with three replications. In the first trial, all fish exposed to triclosan died within 30 minutes. In the second trial, the fish showed clinical signs of intoxication and mortalities between 4h and 24h at the highest concentrations and, at the concentration of 0.5 mg/L, they remained alive for 96 h without any clinical change. Thus, the range between 1mg/L and 0.5mg/L was established as a reference for sublethal experiments. The clinical signs observed wereneurological, such as erratic swimming and spinning, culminating in the death of fish; in addition to clinical signs of hemorrhage, mainly in the gills. With the results obtained, it is concluded that the lambaris resulting from acute exposure to triclosan showed compromised health with clinical signs of intoxication and high mortality. |

| Conteúdo: | Abstract: Pochonia chlamydosporia and Purpureocillium lilacinum are fungal bioagents used for the sustainable management of plant parasitic nematodes. However, their production through submerged liquid fermentation and their use in seed treatment have been underexplored. Therefore, our goal was to assess the effect of different liquid media on the growth of 40 isolates of P. lilacinum and two of P. chlamydosporia. The most promising isolates tested were assessed for plant growth promotion and the control of the two-spotted spider mite (Tetranychus urticae) and the soybean cyst nematode (Heterodera glycines). Most isolates produced > 108 blastospores mL−1 and some isolates produced more than 104 microsclerotia mL−1. Microsclerotia of selected isolates were used to inoculate common bean (Phaseolus vulgaris L.) seeds in greenhouse trials. All fungal isolates reduced the T. urticae fecundity in inoculated plants through seed treatment, while P. chlamydosporia ESALQ5406 and P. lilacinum ESALQ2593 decreased cyst nematode population. Purpureocillium lilacinum was more frequently detected in soil, whereas P. chlamydosporia colonized all plant parts. Pochonia chlamydosporia ESALQ5406 improved the root development of bean plants. These findings demonstrate the possibility of producing submerged propagules of P. chlamydosporia and P. lilacinum by liquid culture, and greenhouse trials support the applicability of fungal microsclerotia in seed treatment to control P. vulgaris pests. |

| Conteúdo: | Abstract: Climate change can cause significant shifts in the occurrence and severity of agricultural diseases, altering the distribution of phytosanitary problems with severe economic, social, and environmental consequences. Despite their importance, these new geographic and temporal distributions of plant diseases still demand scrutiny. In the present study, we prospect the geographic distribution of sugarcane brown rust (Puccinia melanocephala) considering average temperature and relative humidity in the main producing region of the state of São Paulo. The geographic database was structured using GIS with projections of future climate change provided by IPCC. Mathematical logic equations were defined and applied to data of average temperature and relative humidity, resulting in monthly maps of climate favorability for the occurrence of the disease. Prospective maps for three future periods (2011-2040, 2041-2070, and 2071-2100) and two greenhouse gas emission scenarios were compared to the reference period (1961-1990). The analysis considered months from December to May. Our study shows a tendency of decrease in the favorability for the disease in a longer term (2071-2100), more noticeable in the scenario A2 than in B1. These results suggest; however, that this disease demands attention in the management of the producing region for future climate scenarios. |

| Conteúdo: | Abstract: Anastrepha curvicauda (Diptera: Tephritidae) (syn. Toxotrypana curvicauda) is one of the main fruit flies of papaya crop abroad. The insect is an absent quarantine pest (AQP) in Brazil. However, due to its great potential to attack the fruit crop, with economic and social impacts, and because it is present in areas of Venezuela and Colombia, the insect was prioritized among the 20 AQPs for prospective research. The use of ecological niche modeling and geoprocessing techniques, considering respectively the algorithm Genetic Algorithm for Rule-set Production (GARP) in OpenModeller platform and ArcGIS, has contributed to obtaining georeferenced information on national municipal areas favorable to the occurrence of insect pests. Information from technical-scientific literature and from national and international databases was used. This work presents the territorial zoning of Brazilian areas favorable to A. curvicauda in papaya crop, considering ecological niche modeling in GARP, ArcGIS and information from international/national databases on papaya crop, municipalities and climatic factors (GBIF, SIDRA/IBGE, BDMEP/INMET). Suitable areas for the insect were identified in all geographic regions of the country, predominantly in municipalities of the Southeastern, Northeastern, and Southern regions. Suitable microregions of the states were also identified, allowing the observation of their respective municipal concentrations presenting this favorability. The federation units that showed greater municipal favorabilities for the occurrences of this AQP in papaya were Bahia, Minas Gerais, São Paulo, Rio Grande do Sul, Paraná, and Espírito Santo. The results contribute to national phytosanitary defense strategies aimed at preventing the entry of this absent quarantine pest in Brazil. |

| Conteúdo: | Resumo: As nanopartículas de prata (AgNP) vêm despertando grande interesse no meio científico por possuírem propriedades importantes, tais como, condutividade elétrica e térmica, atividade catalítica, flexibilidade, estabilidade química, maleabilidade e o baixo custo de produção. Apesar do desempenho em diferentes função, estudos têm alertados sobre os possíveis efeitos que a AgNP pode causar ao meio ambiente decorrente do aumento de sua produção e utilização. A Lemna minor (Lentilha-de-água) é uma macrófita encontrada em água doce e normalmente utilizada em testes de ecotoxicidade de poluentes ambientais. Este estudo teve como objetivo avaliar os efeitos da AgNP estabilizada em polivinil álcool (PVA) sobre o crescimento, teor de clorofila e massa da matéria úmida da macrófita. As mudas foram expostas em 5 mL de solução teste, com 24 repetições para cada concentração-teste: 0,0; 0,01; 0,1; 1; 10 e 100 mg L-1 de AgNP-PVA. Foi contabilizado diariamente o número de frondes, e ao final do período de exposição de 7 dias foi determinada a concentração efetiva média a 168 horas (CE50-168h) para cada indicador avaliado. A concentração de efeito não observado (CENO) associada à taxa de crescimento, teor de clorofila e peso úmido é respectivamente de 0,326; 0,370 e 0,261 mg L-1 . Os resultados deste estudo em conjunto com o de outros organismos servem como parâmetros de ecotoxicidade para estabelecimento de concentração máximas de proteção das comunidades. |
