Abstract
Abstract The efficacy of selected insecticide treatments was compared with that of an untreated control at the Macon Ridge location of the Northeast Research Station near Winnsboro, LA. Corn seed was planted in a Gigger silt loam (pH = 6.1, 1.1% organic matter) on 27 Mar in 2-row plots (40 inch centers) X 40 ft. Treatments were arranged in a RCB design with four replications. Treatments were applied with a handboom and a CO2-charged delivery system calibrated to deliver 10 gpa through 8002 flat-fan nozzles (2/row) at 28 psi. Insecticides were applied on 14 May to V5 stage corn plants. Ten plants/plot were randomly chosen for sampling on 16 and 20 May. Total numbers of chinch bugs were recorded by visually examining mainstems of the plant and leaf sheaths. Data were analyzed with ANOVA and means were separated according to DMRT. Rainfall did not influence the results of this test.
