insecticide associated with adjuvant application in soybean plants

The insecticide use on insect pest control is an important tool to keep high yields on soybeans. However, little is known about the behavior of the insecticide in adverse conditions, such as spraying followed by precipitation. The use of adjuvants associated with insecticides is another factor that can be related to improvement of its effi ciency. This study aimed to evaluate the effects of the infl uence of four precipitation periods after the pulverization of the insecticide clorantraniliprole (2g of the active ingredient ha -1 ). A mixed of different adjuvants on the control of caterpillars on soybeans were evaluated. The assay was performed using two cultivars in six pots (2 plants/pots) for a factor scheme of 5x5. The factor adjuvants consisted of one untreated (without adjuvants) and four adjuvants (Assist ®
