Abstract
Abstract Ten insecticide treatments were evaluated for efficacy against tarnished plant bugs in cotton at the Macon Ridge Location of the Northeast Research Station near Winnsboro, LA. Cottonseed was planted 1 May in 4 row plots (40 inch centers) X 50 ft. Treatments were arranged in a RCB design with 4 replications. Insecticides were applied on 24 Jul with a high clearance sprayer calibrated to deliver 6 gpa through TeeJet TX-8 hollow cone nozzles (2/row) at 46 psi. Treatments were evaluated 3 and 7 DAT with a standard 15 inch diam sweep net by counting both tarnished plant bug adults and nymphs in a 10 sweep sample/plot. No rainfall was recorded during the test. Data were analyzed with ANOVA, and means were separated according to DMRT.
