Tecnología de aplicación terrestre para el control de insectos en el cultivo de soja

Two trials were conducted for efficiency of spray-deposit distribution and for insect control in soybean crop in Uruguay. In the first one the effects of droplet size, volume application rate and application time in the control of bean shoot borer (Epinotia aporemai W.) were evaluated. The second trial consisted in evaluating the effects of droplet size and application speed in the control of shield bugs (Nezara viridula L. and Piezodorus guildinii W.). Distribution of a fluorescent dye was evaluated by counting impact on the foliage in the middle and upper canopy. Impact density was higher wi...
