Two tests were conducted at the Macon Ridge location of the Northeast Research Station to evaluate the efficacy of selected insecticides against soybean looper and beet armyworm. Plots in both consisted of 4 rows (40 inch centers) X 50 ft, planted 15 Jun and arranged in a RCB with 4 replications. Insecticides were applied in both tests on 23 Aug with a high clearance sprayer calibrated to deliver 11.5 gpa through Teejet TX-8 hollow cone nozzles (2/row) at 44 psi. Treatments were evaluated at 2 and 7 DAT using two 25-sweep samples/plot with a standard 15 inch diam sweep net. Rows 1 and 2 were sampled 2 DAT and rows 3 and 4 were sampled 7 DAT. No rainfall occurred during these tests. Data were analyzed with ANOVA, and means were separated according to DMRT.
