Evaluation of Insecticides for Control of Corn Earworms and Fall Armyworms on Peanuts, 1990

This field test was conducted in conventionally planted and tilled peanut at the Wiregrass Substation in Headland, Ala. Eight treatments and a control were replicated 4 times in a randomized complete block design. Each plot was 4 rows wide (36 inch row spacing) and 50 ft long. Replicates were separated by a 15 ft alley. Treatments were applied in water on 26 Jul using a boom sprayer equipped with 3 TX3 nozzles/row operating at 40 psi and delivering 8.3 gal/acre. Insect populations were monitored by placing a standard 3-ft beat sheet between 2 randomly selected rows and by beating both rows. Samples were taken at 1 hr before treatment and at four and seven DAT.
