Newly registered and soon to be registered insecticides for use on cotton were tested in three representative locations in Northeastern Mexico, in order to assess their effectiveness and provide an alternative to commonly used insecticides, mainly chlorpyrifos, due to the lack of effectiveness. All new products were efficacious in controlling beet armyworm (Spodoptera exigua), and the major difference among them was their speed of action. Chlorfenapyr, RH-2485 and spinosad were the products that demonstrated a greater speed of control. All new products expressed their maximum effectiveness 5-7 days after their application, and because they offer a different mode-of-action, are a good tool for resistance management.
