Now that the bean leaf beetle has focused our attention on pest management in soybean, several questions have arisen regarding insecticide use and performance. Many insecticides are registered for this insect in soybean (Table 1). Some of the insecticides have a short preharvest interval of 28 days or less, but the pyrethroids have much longer intervals; Warrior is labeled at 45 days followed by Ambush and Pounce currently at 60 days. Common concerns have been initial knockdown, residual control, and preharvest limitations.
