Green peppers were transplanted Jun 1 at the University of Massachusetts Research Farm, Sunderland, MA. Plots consisted of 18 ft long beds with 2 rows/bed and 2 ft between plants within rows. Treatments were replicated 4 times in a randomized complete block design. The insecticides were applied Jul 24, 28, and Aug 6, at 75 gal water/acre and 55 psi, using a 3 gal stainless steel sprayer. Five leaves per plant and 10 plants per plot were sampled for green peach aphid and potato aphid apterae on Aug 11. European corn borer control was assessed by harvesting 25 commercial size peppers from each plot on Aug 20 and examining them for injury.
