Abstract
Abstract This test was conducted in conventionally planted and tilled peanuts at the Wiregrass Substation of Auburn University. Eight treatments and an untreated control were replicated 4 times in a randomized complete block design. Each 0.013-acre plot was 4 rows wide (36-inch spacing) and 50 ft long. Replicates were separated by a 10-ft alley. Aqueous treatments were applied 29 Jul from a tractor-mounted boom sprayer equipped with 3 TX-3 hollow-cone nozzles/row operating at 40 psi and delivering 8 gal/acre. Insect populations were sampled by placing a standard 3-ft beat sheet between the rows and beating both rows. Corn earworm larvae were classified as small (first to second instar), medium (third to fourth instar) or large (fifth instar and older); they were then counted and recorded. Three samples from each plot were taken prior to treatment and at 3, 7, and 10 DAT (1, 5, and 8 Aug).
