As we approach the summer months, be alert as temperatures and bean leaf beetle populations begin to rise. After overwintering in leaf litter and soybean residue, bean leaf beetles may already be emerging as they typically begin to appear in April and May. According to Kansas State University, the bean leaf beetle is one of the most economically harmful soybean insect pests in the country due to damage from foliage- and pod-feeding adults, which can significantly reduce seed quality and yield. It may be difficult to recognize this destructive insect as it can appear in a variety of colors and patterns, including red, orange, tan or gray and have dots, stripes or both. All adults possess a black triangle at the base of the forewings which is the easiest identification characteristic.
The University of Missouri Extension recommends scouting for bean leaf beetle begin as soon as soybean seedlings emerge. If you see signs of an infestation, it is important to note that various sampling methods and economic thresholds are used to trigger insecticide applications for bean leaf beetle, so check your local university extension for appropriate application information. When application is warranted, give your fields the best protection from bean leaf beetle by selecting an insecticide with three industry-leading technologies that offers long residual control for higher potential yield and profit.
