Abstract
Abstract This field test was conducted in conventionally planted and tilled soybeans at the Plant Breeding Unit of the E. V. Smith Agricultural Experiment Station near Tallassee, AL. Twelve treatments and a control were replicated 4 times in a randomized complete block design. Each plot was 6 rows wide (36 inch row spacing) and 50 ft. long. Replicates were separated by a 25 ft alley. Insecticides were applied in water on 4 Sep using a CO2 boom sprayer equipped with 2, TX-3 hollow cone nozzles/row operating at 40 psi and delivering 10 gal/acre. Insect populations were sampled by placing a standard 3 ft beat sheet between the rows and beating both rows. Two samples were taken from each plot 18 h before treatment and at 4 and 7 DAT.
