Resumo: |
Spraying for pest and disease control is a complex process that increasingly demands planning. Some important points, such as products characteristics: penetration, absorption, surface tension, spreading, pH decrease, mixtures interaction with adjuvants, impacts of ext ernal factors, are relevant for success. The chemical control has become essential to ensure soybean yield against soybean rust damage, because it is the most efficient method to control. According to manufacturers, the a djuvants are added on commercial fu ngicides formulation s, which provide better performance and reduce losses in the process. The objective of this study was to characterize the functionality of adjuvants on the quality of application and retention and translocation of azoxystrobin fungicide s in soybean leaves. Six treatments from mixtures of Priori Xtra and adjuvants formulated with mineral (Nimbus) and vegetable oils (Óleo Vegetal Nortox) , sodium lauryl sulfate (TA - 35), and nonylphenol (In - tec) were used in the test. It was determined param eters related to surface tension and droplets spectrum, chromatography quantification retention process and translocation of azoxystrobin on the leaves. The results showed that all ... |
