CARACTERÍSTICAS FÍSICO-QUÍMICAS DE CALDAS INSETICIDAS E AVALIAÇÃO DE CONTROLE DO COMPLEXO DE PERCEVEJOS DA CULTURA DA SOJA (Glycine max L.)

Abstract

The knowledge of new techniques for applications of phytosanitary products can contribute satisfactorily to the control of pest insect pests. The objective of this study was to characterize applications with different mixtures of insecticides (Fastac Duo® and Hero®) and adjuvants (Assist®, Prime® and Prime Citrus®) in the soybean crop by means of deposition and cover sprayed, surface tension, and contact angle, perform the population survey as well as the damage caused by the complex of pest bedbugs culture. The data were submitted to the F test and, when significant, the means of the treatments were compared by the Tukey test. The insecticides and adjuvants evaluated provided deposit and similar coverage in the thirds of the soybean plant. They also reduce surface tension and contact angle to water. Hero® insecticide associated with Assist®, Prime® and Prime Citrus® adjuvants have greater uniformity of droplet spectrum than Fastac Duo® associated with the same adjuvants. The Fastac Duo® insecticide associated with the Prime Citrus® adjuvant offers a greater risk of drift in relation to the other treatments. Fastac Duo® and Hero® insecticides are effective in bed bug control and, combined with Prime® adjuvant, provide increased productivity.
