2. MULTIVARIATE ANALYSIS APPLIED TO SPRAY DEPOSITION IN GROUND APPLICATION OF PHYTOSANITARY PRODUCTS IN COFFEE PLANTS
ABSTRACT An adequate combination of factors involved in the technology used for phytosanitary product application contributes to an efficient spray deposition on the target. The objective of this study was to use multivariate analysis to characterize the magnitude of effects and the order of influence of three factors that interfere with the quality of phyto

3. PERFORMANCE OF AIR INDUCTION SPRAY NOZZLE MODELS UNDER DIFFERENT OPERATING CONDITIONS
ABSTRACT For the successful application of phytosanitary products, it is essential to understand the spraying process well. The present work aims to evaluate the spectrum and speed of the droplets produced by different spray nozzle models with air induction, working under different operating conditions. The experiment was conducted using an entirely randomiz

5. Effect of Pesticide Addition Sequence on the Preparation of Phytosanitary Spray Solutions
RESUMO: A adição de adjuvantes às caldas herbicidas visa preservar ou aumentar o efeito biológico do tratamento, porém é comumente realizada sem conhecimento das interações físico-químicas entre os produtos. Assim, objetivou-se neste trabalho avaliar os efeitos sobre a tensão superficial e o ângulo de contato decorrentes de diferentes sequências

6. STUDY OF THE EFFECTS OF ADJUVANTS ASSOCIATED WITH INSECTICIDES ON THE PHYSICOCHEMICAL PROPERTIES OF THE SPRAY SOLUTION AND CHARACTERIZATION OF DEPOSITS ON WHEAT AND MAIZE LEAVES UNDER SIMULATED RAIN
ABSTRACT The association of adjuvants with phytosanitary products has been tested for several years but is commonly recommended without considering technical and scientific criteria. This study aimed to evaluate the influence of the association of insecticides with different adjuvants on surface tension, contact angle, coverage, hydrogen ionic potential (pH)

7. Potato genotypes reaction to early blight and late blight in organic cultivation
RESUMO: O manejo de doenças nos cultivos convencionais de batata requer emprego de maior quantidade de produtos fitossanitários e de maior toxicidade em relação ao cultivo orgânico, que pode acarretar riscos a saúde humana e impacto ambiental. Este trabalho teve como objetivo avaliar o rendimento e a reação de genótipos de batata à requeima e à p

8. Rhizophagus Clarus and Phosphorus in Crotalaria juncea: Growth, Glomalin Content and Acid Phosphatase Activity in a Copper-Contaminated Soil
ABSTRACT Crotalaria juncea is used as plant cover in grape vineyards in Brazil, which usually present soils with high copper (Cu) levels due to the application of Cu-based phyto-sanitary products. Under this condition an increase growth and cover of C. juncea is needed to improve the phytoremediation processes in those soils. Some alternatives to achieve thi

9. Copper supply and fruit yield of young Citrus trees: fertiliser sources and application methods
ABSTRACT This study aimed to evaluate the fertiliser sources and application methods of copper (Cu) in citrus trees during the first years of fruit production. Two experiments were set up in an orchard with 3-year-old sweet orange trees, which were applied with three sources of Cu (nitrate, sulfate or EDTA) either via fertigation (Experiment 1) or via foliar

10. Residual polysaccharides from fungi reduce the bacterial spot in tomato plants
Abstract Polysaccharides from fungal wastes were partially characterized and evaluated for their protective effects against bacterial spot caused by Xanthomonas gardneri on four tomato cultivars: Santa Cruz Kada, Natália, BRS Sena and Forty. The polysaccharides were extracted from spent mushroom substrate of Pleurotus ostreatus, residual brewery yeast (Sacc

11. Algal polysaccharides as source of plant resistance inducers
Algal compounds exhibit great potential to enhance plant growth and resistance to abiotic and biotic stresses. This review focuses on aspects concerning the physical-chemical properties, function and biological activity of macroalgae polysaccharides. Updated results of the main poly- and oligosaccharides studied for the control of plant diseases are discusse

12. Criação de Anastrepha fraterculus (Wied.)(Diptera: Tephritidae) em dieta artificial e avaliação de produtos fitossanitários utilizados no sistema orgânico de produção sobre esta espécie e insetos benéficos / Rearing Anastrepha fraterculus (Wied.)(Diptera: Tephritidae) in artificial diet and evaluation of phytosanitary products used in the organic system of production on this specie and beneficial insects
A mosca-das-frutas sul-americana, Anastrepha fraterculus (Wied.) é um dos principais problemas à produção de frutíferas no Brasil. No sistema orgânico de produção, há diversas alternativas para o controle das moscas-das-frutas, como óleos, extratos de plantas e caldas. Entretanto, para a maioria dessas substâncias, não há a comprovação cientí
