In grain storage, there are problems caused by insect pests, which can cause quantitative and qualitative losses during the storage of seeds and grains. Among the pests, the species, Sitophilus zeamais Mots. 1855 (Coleoptera: Curculionidae) and Lasioderma serricorne (Fabricius, 1792) (Coleoptera: Anobiidae). The control of these stored grain pests is carried out by chemical insecticide. However, there are few products registered to control these stored grain pests. Thus, the search for control alternatives, such as the use of compounds extracted from plants with insecticidal properties, represents a promising alternative. Essential oils and their major components have played a significant role in the development of insecticides. Thus, the objective of this work was to evaluate acute toxicity, effect on survival and emergency and the response of the path of some major components of essential oils, thymol, camphor, terpineol, camphene, eucalyptol, limonene, β-pinene and eugenol and their mixtures about S. zeamais and L. serricorne. The adults of S. zeamais and L. serricorne were subjected to fumigation testing, effect on adult emergence and survival and walking response. The results show that the major components and mixtures caused acute toxicity, reduced the survival time and production of adults and altered the behavioral activity of S. zeamais and L. serricorne. The camphor + camphene mixture showed a synergistic effect, with CL50 and CL90 of 2.77 and 20.34 µl/mL respectively on S. zeamais. The major components eucalyptol and terpineol showed 65% mortality, in which the mixtures terpineol + eucalyptol and camphor + thymol presented 47% and 52% over adults of L. serricorne. The results showed that the major components and mixtures are promising for the development of new insecticides.

A utilização planejada de efluentes orgânicos em cultivos agrícolas possibilita a reutilização da água e promove a incorporação de nutrientes no sistema solo-planta. Objetivou-se, com o desenvolvimento do presente trabalho, avaliar a viabilidade do uso de diferentes taxas anuais da água residuária da suinocultura, em duas safras de cana-de-açúcar (cultivar RB86-7515). O estudo foi desenvolvido durante as safras agrícolas de 2020/2021 e 2021/2022. Os tratamentos constituíram na aplicação de seis doses de água residuária da suinocultura fornecendo 40, 80, 120, 160, 200 e 240 kg ha-1ano-1 de potássio. Foram avaliados os atributos químicos do solo (pH, potássio, fósforo, cálcio, magnésio, capacidade de troca de cátions efetiva e potencial, saturação de bases e acidez potencial) os componentes de crescimento e produção da cultura (produtividade, número de colmos, comprimento, porcentagem de caldo e grau brix) e os riscos de contaminação difusa, pela análise (nitrogênio, sódio, potássio e fósforo) da água proveniente do escoamento superficial armazenada em coletores de plástico instalados em cada parcela experimental após as principais chuvas. No decorrer de dois anos de cultivo, o pH e a saturação por bases do solo reduziram, enquanto os teores de potássio, fósforo, capacidade de troca de cátions efetiva e potencial, cálcio, magnésio, e acidez potencial apresentaram aumento dos valores. Em função da dose de água residuária de suinocultura aplicada o pH, o fósforo, o potássio, o cálcio, o magnésio, a saturação de bases e a capacidade de troca de cátions potencial apresentaram aumento enquanto a capacidade de troca de cátions efetiva e a acidez potencial apresentaram redução. A utilização de maiores taxas de água residuária de suinocultura promoveu aumento da produtividade e redução do número de colmos e comprimento, a porcentagem de caldo diminuiu da primeira para segunda safra e grau brix aumentou. No estudo referente ao risco de contaminação difusa, os teores de nitrogênio, sódio, potássio e fósforo da água de escoamento superficial aumentaram com o incremento da dose de água residuária de suinocultura aplicada.

Faced with population growth and the growing demand for food, together with restrictions on natural resources essential to agricultural production, especially soil and water, it is crucial to investigate technologies that enable greater productivity, without depleting natural resources, with a conservationist approach. This implies reducing dependence on chemical inputs external to the productive agricultural ecosystem. Microbial bioinputs represent promising technologies due to their ability to modulate plant responses to overcome biotic and abiotic stresses. Furthermore, they demonstrate to be responsive in conservation-based environments, such as the no-till system. The use of waste in agriculture presents itself as a complementary alternative to this production system, as it allows the appropriate disposal of an environmental liability, such as, for example, wastewater from pig farming, with great potential for being used as fertilizer. The great virtue of this study is the generation of a technology that allows the joint use of bioinputs (efficient microorganisms), wastewater from pig farming and direct planting systems with a view to making agriculture less dependent on the use of human and industrial water supplies, as well as as well as fertilizers. Therefore, the objective of this study was to evaluate microbial bioinputs formulated with Herbaspirillum seropedicae (strain HRC54) and Azospirillum brasilense Ab-V5 (CNPSo 2083) and Ab-V6 (CNPSo 2084), applied as a single inoculum or co-inoculated, and to understand its action on maize cultivation (Creole maize, Fortaleza variety) in different soil conditions. These conditions were represented by different soil management systems: direct planting system and conventional planting system, irrigated with different levels of pig farming wastewater and raw water. To this end, three experiments were conducted, carried out in greenhouse and field conditions, in different treatment configurations, which are presented in three chapters of the thesis. In chapter 1, developed in a greenhouse, under co-inoculation conditions (H. seropedicae + A. brasilense), microbial bioinputs showed a synergistic effect on soil with higher biological quality. In chapter 2, carried out in a xii xii greenhouse, an experiment evaluated under water restrictions, it was noted that bioinputs had a more significant contribution to physiological attributes in treatments with a history of conventional planting systems, highlighting their effectiveness in mitigating abiotic stresses. In chapter 3, which was carried out under field conditions, the effects of coinoculation in different management systems were investigated. It was highlighted that the direct planting system, together with irrigation with wastewater from pig farming, created an environment more favorable soil conditions, providing a more favorable biological quality for the growth of the microbial population introduced into the system, which, in turn, allowed greater development of the maize crop.

The study of biometric characteristics and crop yield of coffee has been useful for the process of selecting superior genotypes, due to the increasing demand for cultivars adapted to the most different cultivation conditions, contributing to the increase of competitiveness and sustainability of coffee crops. In addition, it is possible that a wide range of descriptors related to agronomic traits, aspects of the crop yield, photosynthetic performance, fruit morphology and water use for production can be used to study the variability among coffee genotypes. In this context, the main objective of this study was to analyze the biometrics, crop yield and photosynthesis of genotypes of Coffea canephora, selected for beverage quality, based on an experimental field with 27 genotypes of Conilon coffee (three clonal cultivars with nine genotypes each), following a randomized block design, with four replications, cultivated in the municipality of Castelo-ES, at an altitude of 126 m, using spacing of 3.0 × 1.0 m. In the first chapter, the variability for agronomic traits and crop yield of the 27 genotypes of C. canephora was analyzed. Fifteen characteristics related to canopy architecture, biometry of plagiotropic branches, classification of grains and mean yield along harvests were evaluated. In each harvest, the yield of each genotype was evaluated. With the results, it was possible to observe the expression of variability among the genotypes of Conilon coffee for the evaluated traits. There was a greater number of groups formed among genotypes based on the crop yield, classification of grains, canopy height, length of internodes of the plagiotropic branch, and total accumulation of dry mass per plagiotropic branch. The genotypes 108 and 201 were the most productive, considering the average of four harvests, highlighting the genotype 201 due to the smaller variation of crop yield, demonstrating greater stability over time. In contrast, the genotypes 203 and 307 were the least productive, while the genotype 106 presented the larger amplitude of production along harvests. In the second chapter, the variability for photosynthetic performance of the 27 genotypes of Conilon coffee was analyzed, by measuring the gas exchange rates and chlorophyll contents at the period most favorable for the photosynthetic activity of the plants (between 8 and 11 a.m.), during different stages of the reproductive cycle: flowering, fruit initiation (pellet-like berry), grain formation and fruit maturation. The photosynthetic performance was expressed as the average (weighted by the number of days) of the gas exchanges and chlorophyll contends sampled in the morning period and in the referred phenological stages of the 2017/2018 crop. With this, it was possible to verify the variability among the 27 genotypes for photosynthetic performance for the reproductive cycle. Among the physiological traits, the carbon assimilation rate, the stomatal conductance and the transpiration rate are highlighted as parameters for the study of variability, mainly due to their contributions to clustering the genotypes. The genotype 108 stood out for a high photosynthetic rate associated with higher chlorophyll contents, as well as reasonable water use efficiency; and the genotypes 205, 206 and 305 for the results in terms of instantaneous carboxylation efficiency, water use and carbon assimilation. In the third chapter, the objective was to evaluate the characteristics and dimensions of the fruit of the 27 Conilon coffee genotypes, as well as to assess the use of this information to study the variability among genotypes. Between the months of May and August 2018, samples of fruits from each genotype were harvested at the stage of maturation to evaluate 15 traits related to the dimensions and mass distributions of structures of ripe fruits and seeds. Among the analyzed traits, the longitudinal length, the total dry mass and the smaller transverse length of the fruits played a fundamental role in the study of variability and in the definition of clusters among genotypes. Overall, the genotype 208 presented fruits with larger main lengths, as well as larger surface area, unitary volume, total content of soluble solids and total dry mass of the fruits, in addition to a higher mass ratio allocated in the grains. The genotype 302 presented contrary results to those observed for the genotype 208. Lastly, in the fourth chapter, the objective was to evaluate the productive efficiency of the 27 genotypes of C. canephora considering the amount of water made available along the productive cycles. During each cycle, the amount of water added to the experimental field through irrigation and precipitation was accounted. After each harvest of the fruits, the crop yield of processed coffee for each genotype was calculated and, by dividing the coffee production of each genotype after each harvest by the amount of available water for that cycle, the efficiency of the production in function of the amount of available water was obtained. There was differential behavior among the 27 genotypes for production efficiency in each cycle, as well as significant differences in efficiency along the years for most genotypes. The genotypes 108 and 201 stood out for presenting, on average, the highest efficiencies, while genotypes 203 and 307 stand out for the lowest. The genotype 102 did not significantly change the production efficiency along cycles, being elected as the most stable among the genotypes. In the current climatic scenario of the regions where coffee is cultivated, the study of the behavior of genotypes of Conilon coffee for productive efficiency arises as a tool to contribute in the selection of genotypes with greater capacity to use the available water.

Brazil is the world's largest producer and exporter of coffee (Coffea spp.) and the second largest exporter of conilon coffee. However, fungal diseases such as stem canker of coffee trees (SCC), caused by Fusarium spp., have the potential for damage up to 100% in susceptible C. canephora genotypes. The disease is currently being managed without specific control methods, such as resistant genotypes and fungicides. In this sense, the objective was to characterize the resistance of clones and the effectiveness of fungicides for the control of SCC, caused by F. solani. For the resistance experiments, seedlings of 36 C. canephora clones, 20 from the robusta varietal group and 16 from the conilon varietal group, were inoculated with F. solani using the Mycelial Inoculation in Wounded Stems (IMC) method, transferring discs of mycelium and spores of the pathogen, grown on potato-dextrose-agar (PDA) for 10 days, for longitudinal sections in the stem of each sampling unit. The quantified disease data over time were subjected to analysis of variance, Scott-Knott mean tests and bootstrapping with the aid of R software, grouping clones according to resistance. For the variable internal lesion length (cm) and according to the Scott Knott tests, the clones Imbigudinho, Bamburral, Bicudo, P2, AD1, A1, AP and Peneirão were grouped among the most resistant of the conilon varietal group, while G20, L33, VR4, R22, R40 and 7 were the most resistant clones of the robusta varietal group. For F. solani mycelial growth inhibition and chemical control experiments, ten fungicides (Met+Flu, Dif+Pid, Cyc, Tia, Tia+Flu+Met, TioMet+Flu, Pid, TioMet, Pro+Nap and Flu) were tested in preventing mycelial growth F. solani in increasing doses between 0.0001-10000 µg.mL-1 in PDA culture medium. The EC50, effective concentration to inhibit 50% of the pathogen, estimated according to the log-logistic model LL2.3 in the R software, was between 0.06-5.77 µg.mL-1 in our results, and only the fungicide Flu was considered inefficient, with EC50 greater than 50 µg.mL-1 . At greenhouse, four doses of nine fungicides were sprayed preventively before inoculation, inoculated with F. solani by the IMC method on C. canephora seedlings with three pairs of leaves (clone LB1). Based on Kaplan-Meier curves estimates in the R software and log-rank tests, fungicide application tested for reducing symptoms and dry branches. The fungicides Pro+Nap, TioMet, Dif+Pid, TioMet+Flu, and Cyc were the most efficient, with no plant drought occurring at the highest doses under study, with a probability of plant survival of up to 100% throughout the entire experiment. The results obtained in this study will be essential to establish more efficient integrated management of SCC, an important disease expanding in C. canephora producing regions in Brazil
