Regional and Urban Development Under the Signs of Globalization: The Soybean Complex and the City of Agribusiness in Mato Grosso

Since the 1960s, the integration of local economic activities into global structures has fostered a continuous increase in the production of cash crops in Brazil. This has led to a far-reaching transformation of formerly peripheral regions. Given their wide range of uses, soybeans are a prime example of flex crops, which are becoming ever more important in global agribusiness. Soybean cultivation stands out as the main cause of widespread land use changes in many South American regions. The Brazilian state of Mato Grosso is one of the world’s most important soy-growing regions, leading to controversial socioeconomic and environmental impacts. Drawing on the case of Sinop, the “City of Agribusiness,” and its surrounding region, this article analyzes the complex territorial manifestations of global soybean production networks. We illustrate both the actor networks of agro-industrial soy production, as well as their functional interconnectedness and institutional embeddedness. Finally, we point out growing social-ecological problems caused by the ongoing soy boom. In doing so, the global production network approach offers great explanatory power for understanding global-local interdependencies and interactions.

Unravelling the identity of pest thrips (Thysanoptera: Thripidae) of bananas (Musaceae) in Brazil

AbstractA total of eight species of thrips (Thysanoptera: Thripidae) have been listed as banana pests in Brazil. Their feeding and oviposition behaviour on these fruits damage their appearance in ways that can impair commercial value. As a result, taxonomic studies that seek to correctly identify thrips can positively impact the cultivation of bananas. Many earlier records of banana thrips in Brazil consist of doubtful identifications or untraceable reports. In this paper, the identification of these banana pests in Brazil is revised and an illustrated identification key is provided. The specimens examined were collected over a period of 10 years from the most representative banana-growing areas in Brazil. Seven banana thrips in Brazil are now recognised:Bradinothrips musae(Hood),Chaetanaphothrips orchidii(Moulton),Danothrips trifasciatusSakimura,Elixothrips brevisetis(Bagnall),Frankliniella brevicaulisHood,Frankliniella parvulaHood, andHoodothrips lineatus(Hood).Chaetanaphothrips orchidiiandDanothrips trifasciatusare recorded for the first time as causing damage to banana crops in Brazil. In addition, the following three species are considered misidentifications and should be disregarded as banana pests in Brazil:Frankliniella fulvipennisMoulton,Hercinothrips bicinctus(Bagnall), andHercinothrips femoralis(Reuter).

Resistance of sorghum hybrids to sorghum aphid.

The aphid Melanaphis sorghi (Theobald) (Hemiptera: Aphididae), which infest the sorghum crop, has been an economically important pest which have been causing severe damage to sorghum crops in Brazil since 2019. These species have been observed mainly at the end of vegetative stage and beginning of reproductive stage of plants. Their high reproductive rate on sorghum raises concerns about these pests. Therefore, the present study aimed to estimate the life expectancy and fertility tables of Melanaphis sorghi fed on 15 hybrids of grain sorghum, in order to know the resistance characteristics of these materials and understand how plant resistance can help manage this insect. This study was carried out in a laboratory at 26±2 ºC and 60±10% R.H (relative humidity). Fifty insects were kept in each hybrid, each insect was considered one repetition. According to biological parameters and fertility life table, hybrids BRS373, DKB590 and 50A10 were less suitable for the sugarcane aphid multiplication. Thus, these hybrids could be useful to manage this pest, since the population growth speed is one of the worst problems for the implementation of cropping systems. Genotypes AG1090, MSK327 and XGN1305 favored the development of this pest and, when chosen within a cropping system, other management strategies should be considered.

Fungivory: a new and complex ecological function of Doru luteipes (Scudder) (Dermaptera: Forficulidae).

We report the discovery that the earwig predator Doru luteipes (Scudder, 1876) (Dermaptera: Forficulidae) feed on Puccinia polysora Underw uredospore, the causal agent of Southern Rust of Corn (SRC), which is a primary disease affecting the maize crop in Brazil. We performed experiments in laboratory and greenhouse to test the effect of D. luteipes (1st/2nd and 3rd/4th instars, and adults) fungivory on the P. polysora uredospore concentration. All trials showed a significant reduction of the initial concentration of uredospore. There was a reduction in uredospore concentration with increase in number of D. luteipes feeding on them. We also tested the uredospore consumption by quantifying its percentage in the feces of D. luteipes. Nymphs of the 2nd, 4th instar and adults fed 88%, 85%, and 83.8% of the uredospore, respectively. For nymphs of the 3rd instar, the percentage of uredospore consumption (75.6%) was statistically significant compared with the other groups. In greenhouse experiment, at twenty-eight days after plant inoculation with 9.9 x 104 uredospores, the percentage of uredospore consumption was 81.7%. Our results confirmed the fungivory of D. luteipes on P. polysora uredospore. This is the first report of D. luteipes fungivory, which may play an important role in the biological control of P. polysora in corn.

ARTIFICIAL NEURAL NETWORKS TO PREDICT EFFICIENCIES IN SEMI-MECHANIZED BEAN (Phaseolus vulgaris L.) HARVEST

Bean is among the most consumed and produced crops in Brazil. Given the high demand for food, the search for technologies and controllers to increase the efficiency of agricultural systems has grown. This study aimed to model artificial neural network (ANN) architectures to predict mechanical efficiencies in the semi-mechanized bean harvest. We used a multilayer perceptron network with three inputs (harvest moisture, threshing rotor rotation, and feed rate), two hidden layers of neurons, and one output (efficiency). We evaluated the efficiency in the header, separation on the threshing rotor, cleaning of sieves, and the total efficiency of the machine. ANN was processed by a scripted algorithm to model the network, alternate the number of neurons in hidden layers, as well as to select, test, and validate ANN with less error. ANN was validated by comparing its results with the experimental data. The architectures selected to predict efficiencies were 3-8-15-1 for the header, 3-9-7-1 for the thresher and separation, 3-5-11-1 for cleaning, and 3-15-10-1 for the total operation. ANN predicted satisfactory results with errors below 1% and a high hit rate, thus being valid to predict the efficiencies in the semi-mechanized bean harvest.

Substâncias húmicas: efeito no crescimento e na produtividade de plantas de batata

ABSTRACT The results from humic substances (HS) application in varied crops and conditions are controversial, and the experiments with the potato crop in Brazil are scarce. The objective of this study was to evaluate the effects of HS doses on the growth and yield of two potato cultivars. Four doses of HS were tested: 0, 5.05, 10.10, and 15.15 L ha-1, applied in the planting furrows of cvs. Agata and BRS F63 Camila, in Guarapuava-PR, in the 2015 and 2016 crop seasons, between October and February. The experiment was carried out using a randomized complete block design, in a factorial scheme (crop season x dose x cultivar), with four replications. Plant samplings were performed at tuber initiation, flowering, tuber bulking, and plant maturation growth stages. After shoot senescence, the total and commercial tuber yields were evaluated. Cultivars responded similarly to HS application, with no significant interaction between HS and cultivars, for most assessed variables. At tuber initiation, there was a negative linear effect of HS doses on leaf area index, number of formed tubers, and tuber and total plant dry weight. In the other evaluations, the effect of HS application was not observed regarding the assessed variables. Likewise, no effects were detected on the number and fresh weight of tubers in total and commercial yields. We concluded that HS application affected both cultivars similarly, hampering initial plant growth and not increasing potato yield.

Tolerance of sugarcane cultivars to Mahanarva fimbriolata

ABSTRACT: Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae), the sugarcane spittlebug, is one of the most important pests of this crop in Brazil. The magnitude of its damage depends on the pest population, the plants size when they are infested and the cultivar tolerance. The knowledge about those parameters allows the elaboration of the spittlebug management matrix, in which small plants and less tolerant varieties fields are prioritized for sampling and controlling in relation to developed plants and tolerant varieties fields. Therefore, this study aimed to evaluate the response of sugarcane genotypes to M. fimbriolata, so that they can be correctly allocated in the management matrix. Two experiments were carried out under laboratory conditions using a randomized block design with treatments in a factorial arrangement of 2×11 (experiment 1) and 2×21 (experiment 2), with six (experiment 1) or five replicates (experiment 2). The first factor included two levels of infestation (infested and noninfested plants with spittlebugs), while the second consisted of the cultivars. Cultivars IACSP01-5503, CTC 9004 and RB925211 were considered tolerant to spittlebug, they did not show significant reductions in aboveground biomass, despite showing symptoms of pest attack, as leaves yellowing, while CV6654 and IACSP01-3127 were the least tolerant cultivars, showing the highest reduction in aboveground biomass due to M. fimbriolata infestation. Thus, CV6654 and IACSP01-3127 should be prioritized for sampling and control over the others. On average, spittlebug infestations caused 30.9 % of reduction of aboveground biomass.

BIOLOGICAL CONTROL OF 𝘛𝘦𝘵𝘳𝘢𝘯𝘺𝘤𝘩𝘶𝘴 𝘶𝘳𝘵𝘪𝘤𝘢𝘦 KOCH (ACARI: TETRANYCHIDAE) WITH THE FUNGUS 𝘉𝘦𝘢𝘶𝘷𝘦𝘳𝘪𝘢 𝘣𝘢𝘴𝘴𝘪𝘢𝘯𝘢 (BALS.) VUILL., ON GRAPEYARD

The spider mite, ( Tetranychus urticae ), causes considerable damage in a large number of crops in Brazil. In the grape, the species causes serious damage to the leaves, with necrosis and premature fall, damaging the photosynthesis of the plant and consequently the production and quality of the fruits. The control of the spider mite is carried out predominantly in a chemical way, whose environmental impact can be significant. The incorporation of biological methods would reduce the legal, environmental and public risks of the use of chemical products, mainly for the in natura . In order to provide an alternative strategy to control the T. urticae to grapeyard in the northwest region of São Paulo, the study aimed to evaluate the viability of biological control through the use of the pathogenic fungus Beauveria bassiana under the conditions local climatic conditions under different dosages. They were sprayed in a vineyard area of the BRS-Vitória variety in Palmeira d'Oeste/SP, four combinations of products based on B. Bassiana , with and without mineral oil, in addition to a treatment containing only mineral oil, which were compared with the control in relation to the effect on eggs and adults of the spider mite and also its effects on their mortality. No significant results of the application of B. bassiana on the occurrence of eggs and adults of T. urticae were observed, even with the addition of mineral oil. However, there were positive results of the fungus application on mite mortality. Longer evaluation periods could provide better efficiency results.

Sensing of pheromones from Euschistus heros (F.) stink bugs by nanosensors

This revision covers the agriculture system, the losses due to insect pest, the pheromone definition and how they can be deployed. Specially, this work focus in pheromones from stink bug Euschistus heros. The use of different techniques for pest control in agriculture seeks safety and environmental preservation. The stink bug E. heros is one of the major pests that affects crops in Brazil. This insect releases pheromone to mate in low amounts. A promising and efficient alternative for the detection of this volatile compound is the use of nanosensors. This paper provides a review of the most recent works in nanosensors used for detection insect pheromones, including gas sensors with sensitive coatings in nanoscale. Also, other applications of gas nanosensors in pheromone detection in agriculture are described. Nanosensors are potential solutions for pest management and can contribute to developing innovative and technological solutions for agriculture.

A Comprehensive Review of the Coffee Leaf Miner Leucoptera coffeella (Lepidoptera: Lyonetiidae)-A Major Pest for the Coffee Crop in Brazil and Others Neotropical Countries.

Simple SummaryCoffee is produced in more than 60 countries by 25 million coffee producers, most of whom are smallholders in emergent countries. More than a beverage intake, coffee has become a ritual for an increasing number of consumers across the globe. This rising market demands modern management to improve grain quality, environment protecting, and produce pesticide-free products. Among several challenges to overcome, the coffee leaf miner (CLM) pest is one of the most severe threats to the coffee crop, especially in neotropical countries, such as Brazil, the world’s largest producer. Responsible for losses ranging from 30–70%, the CLM impairs the grain production and quality, which negatively reflects on the coffee production chain. Drawback aspects caused by chemical control with pesticides, such as the harmful effects to human health and environment and the selection of resistant-insect populations, prompt scientists to improve integrated pest management (IPM) tools. Therefore, the development of new resistant cultivars, biological control, nano-biopesticide products and other approaches are important strategies to a sustainable CLM control design. This review addresses basic knowledge of the insect L. coffeella and proposes novel insights for an IPM view.The coffee leaf miner (CLM) Leucoptera coffeella moth is a major threat to coffee production. Insect damage is related to the feeding behavior of the larvae on the leaf. During the immature life stages, the insect feeds in the mesophyll triggering necrosis and causing loss of photosynthetic capacity, defoliation and significant yield loss to coffee crops. Chemical control is used to support the coffee production chain, though market requirements move toward conscious consumption claiming for more sustainable methods. In this overview, we discuss aspects about the CLM concerning biology, history, geographical distribution, economic impacts, and the most relevant control strategies in progress. Insights to develop an integrated approach for a safer and eco-friendly control of the CLM are discussed here, including bio-extracts, nanotechnology, pheromones, and tolerant cultivars.

Antixenosis in cotton genotypes (Gossypium hirsutum var. marie galante) to Spodoptera frugiperda (Lepidoptera: Noctuidae) mediated by trichome and gossypol densities

Cotton (Gossypium hirsutum L.) is one of the most important crops in Brazil and pest incidence limits its yields. The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), native to tropical and subtropical America, spread and rapidly became an invasive pest worldwide. It is a polyphagous pest that feeds on up to 353 plant species including cotton. The objective of this study was to evaluate the antixenosis to S. frugiperda in 27 cotton genotypes, comparing varieties with non- commercial genotypes. The attractiveness was estimated in no-choice and free-choice tests, offering leaf discs of the 27 cotton genotypes to S. frugiperda, and counting the number of caterpillars feeding at 3, 5, 10, 15, and 30 minutes and 1, 2, 6, 12, and 24 hours after their release. The numbers of trichomes and gossypol glands per cm2 were measured on abaxial and adaxial surface. The free-choice test was performed in a randomized block design with the 27 genotypes (treatments) and 20 arenas (replicates). The no-choice assay was conducted as a completely randomized design with 18 genotypes and 20 replicates. The non-commercial genotypes PI0440, CE0467, PI0416, BA0512 and MA0425 presented antixenosis against S. frugiperda. In the free-choice test the cultivar BRS Buriti and the genotype PI0429 were the most attractive to S. frugiperda, while in no-choice test, the genotype PI0429 was the most attractive. High trichome density and gossypol glands did not influence the attractiveness of S. frugiperda in cotton genotypes, while the absence of trichomes was repellent to the caterpillars. There is polymorphism among cotton genotypes to attractiveness to the pest, and the genotypes with antixenosis can be used in future study in plant breeding program as donor source of resistance to S. frugiperda

Eight Decades of Dalbulus maidis (DeLong & Wolcott) (Hemiptera, Cicadellidae) in Brazil: What We Know and What We Need to Know.

The corn leafhopper Dalbulus maidis (DeLong & Wolcott) is one of the most important maize (Zea mays L.) pests in Latin America because of its ability to efficiently transmit pathogens [maize bushy stunt phytoplasma (MBSP) and corn stunt spiroplasma-Spiroplasma kunkelli Whitcomb et al. (CSS)] associated with corn stunt disease complex and maize rayado fino virus (MRFV). This leafhopper species, considered a secondary pest until a few years ago, was first reported in Brazil in 1938. Since 2015, corn stunt diseases have been the main phytosanitary threat to corn production in Brazil, and D. maidis has assumed the status of a key pest of the crop. In this study, we gathered pertinent information about the corn leafhopper, from the time it was first recorded in Brazil. Aspects such as origin, association with maize, bioecology, geographical distribution in the Americas, and its congeners are addressed. We present a history of studies performed with this species in the country, its importance as a pest, host plants, and survival strategies during the maize off-season. Based on the available scientific knowledge, the main management strategies for insect vectors and diseases are discussed. Finally, the main knowledge gaps for this insect vector and the prospects for future studies and actions to mitigate the damage caused by insect vectors in maize crops in Brazil are presented and discussed.

NemaNet: A convolutional neural network model for identification of soybean nematodes

Phytoparasitic nematodes (or phytonematodes) are causing severe damage to crops and generating large-scale economic losses worldwide. In soybean crops, annual losses are estimated at 10.6% of the world production. Besides, the identification of these species through microscopic analysis by an expert with taxonomic knowledge is often laborious, time-consuming, and susceptible to failure. From this perspective, robust and automatic approaches are necessary for identifying phytonematodes that are capable of providing correct diagnoses for the classification of species and subsidizing of all control and prevention measures. This work presents a new public data set called NemaDataset containing 3063 microscopic images from five nematode species with the most significant damage relevance for the soybean crop. Additionally, we propose a new Convolutional Neural Network (CNN) model defined as NemaNet and present a comparative assessment with thirteen popular models of CNNs, all of them representing state-of-the art classification and recognition. The general average was calculated for each model, on a from-scratch training; the NemaNet model reached 96.76% accuracy, while the best evaluation fold reached 98.04%. When training with transfer learning was performed, the average accuracy reached 98.82%. The best evaluation fold reached 99.35%, and overall accuracy improvements of over 6.83% and 4.1%, for from-scratch and transfer learning training, respectively, compared to other popular models were achieved. • Detect phytonematodes in soybean crops in Brazil using convolutional neural network. • A new dataset with five main species of phytonematodes from Brazil's soybean culture. • Evaluation of thirteen most popular CNN's architectures and new model (NemaNet). • Results describe NemaNet reaches best results in identifying nematodes overall.

EFFECT OF POULTRY LITTER BIOCHAR ON THE NUTRITIONAL STATUS OF CORN1

ABSTRACT Corn, one of the main grain crops in Brazil, needs to have its nutritional requirements fully satisfied to achieve high biological productivity. Thus, the objective of this work was to evaluate the influence of increasing doses of poultry litter biochar on nutrient concentrations in the leaves of hybrid corn BRS 2022 and in the soil after harvest. The experiment was carried out in a completely randomized design, with four replicates, evaluating six doses of biochar (0; 2.02; 4.05; 6.07; 8.10 and 10.12 t ha-1) and the plots composed of one plant per pot with a volume of 20 dm3. The collection of leaves for leaf diagnosis was carried out at the time of flowering, removing the opposite leaf from the ear base in the middle third region. These leaves were dried in a forced air circulation oven, 65 °C, for a period of 48 hours, ground, sieved through 20 mesh and analyzed for the concentrations of macronutrients in the leaf tissue. At the end of the experiment, 83 days after corn sowing, soil samples were collected as a function of the treatments and then analyzed chemically. Biochar application promoted an increase in the leaf contents of N, P and K, resulting in improvements in the nutritional status of plants for these nutrients. The chemical characteristics of the soil, analyzed after the corn harvest, revealed that there was an influence of the doses of biochar on the levels of calcium, organic carbon, potassium and phosphorus.

Phytotoxicity of aqueous extract of Ilex paraguariensis A.St.-Hil on Conyza bonariensis (L). Cronquist

Crop infestation species have acquired resistance to herbicides, stimulating the search for new control methods. Plants secondary metabolites can hold more sustainable alternatives, as they can be used for development of natural herbicides. This study evaluated phytotoxic effects of aqueous extracts of Ilex paraguariensis leaves on Conyza bonariensis, an infesting species of Brazilian crops. Different concentrations of decoction and infusion extracts were tested in germination and growth bioassays. Adult plants were evaluated for leaf anatomy effects caused by the yerba mate extract. HPLC analysis was used to quantify the three major chemical constituents. The most effective aqueous extract (decoction 1.0%) decreased the percentage of seed germination, germination speed index, and percentage of germination-derived seedling formation, and increased the time for seedling formation. Shoot and root growth were not affected by this extract. In adult plants, the same extract damaged epidermis and palisade/lacunous parenchyma six hours after exposure. Caffeine was found as the major compound of this extract, followed by rutin and quercetin. Therefore, aqueous extract by decoction 1.0 % of I. paraguariensis leaves showed potential for control of C. bonariensis infestation and rather promising for the development of a natural herbicide.

Taking measure of an escape crop: Cassava relationality in a contemporary quilombo-remnant community

Cassava (Manihot esculenta) is among the most important crops in Brazil, not only due to its widespread cultivation and consumption, but also its history in the country. This root has been important both to the colonial project and the resistance to it, particularly in the quilombo-communities. Such sites of resistance have served as paradigmatic examples of ‘escape agriculture’ in the work of James Scott (2009), who highlights the role roots play in avoiding appropriation by the state. In this article, we experiment with the concept of ‘escape crops’ as we follow cassava from harvest to market in a contemporary quilombo-remnant community, Espírito Santo do Itá (Pará). We combine Scott’s attention to the politics of crops with material semiotic sensibilities, thus exploring relationality and performativity. We argue that the cassava is central to the social life in the community, which is organized around the casas de farinha (flour mills). The processing practices also seem to foster a strong sense of collectivity and subjectivity, shaped by the materiality of the crop. Furthermore, the cassava which is performed in these spaces does not seem to allow for standardizations and abstractions, requiring processes of translation in order to be sold in the market, which is done through measuring operations. Through these operations, the cassava becomes an ambivalent and partial market entity, allowing for the cassava to travel in and out of the community, while at the same time precluding a co-option of this space by a capitalist logic. It seems, then, that by extending Scott’s concept, this root continues to be relevant for the community’s autonomy and freedom - not due to the crop’s biological traits alone, but due to the traits it gains and sheds relationally.

Inovação em cultivares: panorama das proteções e registros da soja no Brasil

Technological innovations applied to seeds has been supported in Brazil. The establishment of legal mechanisms of intellectual protection and rules to commercialize plants and seeds were responsible for the growth of research and development of new crops. The soybean is the main crop produced in the past years in Brazil and, for this reason, the main goal of this research is to show the scenario of innovation technology of soybean seeds, highlighting the protection and records of crops in Brazil. The scope of our analysis reaches the period between 1998 to 2018.The questionnaire survey of quantitative approach and descriptive strategy was collected based on information from CultivarWeb database (in special from SNPC and RNC) from Ministério da Agricultura Pecuária e Abastecimento – MAPA (Ministry of Agriculture, Livestock and Supply). The secondary data were worked on Excel® Software by using descriptive statistics. The result of this questionnaire survey showed that EMBRAPA (Brazilian Agricultural Research Corporation) is the main public institution active in seed innovations and leader with the most important protection certifications and soybean crop records in Brazil. We also observed strong participation from foreign companies in this market, especially the ones that support the protection and record of transgenic soybean crops. We concluded that the number of records of soybean crop commercialization are higher than the protection certification.

Occurrence of Pseudomonas fluorescens and P. putida associated to tomato pith necrosis in Brazil

ABSTRACT In 2016, several reports emerged of fresh-market staked tomato plants with severe symptoms of pith necrosis and premature death in commercial cultivation areas in the states of Paraná and Minas Gerais, Brazil, which are similar to those caused by Pseudomonas corrugata. Four bacterial strains were isolated from infected tissue samples and characterized as Gram-negative, aerobic, and fluorescent on King’s B Medium. LOPAT tests were performed and the isolate UFU H120 was classified into group Vb (+ + − + −) and the isolates UFU H3, UFU H6, and UFU H21 into group Va (− + − + −). The pathogenicity of the isolates was confirmed by artificial inoculation on tomato plants of Santa Cruz type, cv. Kada Gigante, and Koch’s postulates were accomplished successfully. The isolates sequences of their 16S rRNA gene region were compared with those deposited in GenBank, the isolate UFU H120 aligning with Pseudomonas fluorescens (99,45% similarity) and the isolates UFU H3, UFU H6, and UFU H21 with Pseudomonas putida (99.2, 99.53 and 99.64% similarity, respectively). Notably, P. fluorescens and P. putida are most known as saprophytic bacteria normally present in the soil, although both of these species have already been reported to infect tomato plants in Italy. However, so far, there have not been any reports of such bacteria being phytopathogenic on tomato or any crop in Brazil. Thus, to our knowledge, this is the first report of pith necrosis of such occurrence in Brazil.

Spatio-Temporal Distribution of Digitaria insularis: Risk Analysis of Areas with Potential for Selection of Glyphosate-Resistant Biotypes in Eucalyptus Crops in Brazil

The objective of this study was to model the spatio-temporal distribution of Digitaria insularis (D. insularis) and analyze the risk of selection of glyphosate-resistant biotypes in eucalyptus cultivation in Brazil. Global data on the distribution of the specie were collected and associated with their ideal growth characteristics. The models were generated using Climex software, providing a predictive modeling technique. Biological data, species distribution, and climatic parameters were used to predict and map potential areas for the species of interest through the combination of growth and stress indices, giving rise to the Ecoclimatic Index (EI). The spatial distribution of D. insularis is predominantly in South and Central America and southern North America. The model had a good fit with the collected data and predicted higher EI values for tropical and subtropical regions, as was the case in Brazil. Species growth can occur throughout the year, with lower rates in winter, mainly in the country’s southern regions. Brazil has high climatic suitability for the occurrence of Digitaria insularis. Due to the climate suitability evidenced by the models and the expressive use of the same active ingredient, there is a risk of selecting glyphosate-resistant Digitaria insularis biotypes in eucalyptus cultivation areas.
