Thrips and Bollworm Control in Bt Cotton 1996

Cotton was planted 25 May 1996 on the Judd Hill Plantation near Truman, AR in Mhoon sandy loam soil. Plots were 8 rows (38 inch centers) wide and 40 ft long separated by 2 unplanted rows and 10 ft alleys. Irrigation was supplied by flooding furrows. Treatments were arranged in a RCBD with 4 replications. Temik was applied at planting using Gandy boxes. The sidedress application was made on 3 Jul. Baythroid was applied using a 4-row CO2 charged backpack sprayer calibrated to deliver 13 gpa at 20 psi with 1 TJ-50 8002vs nozzle per row. Thrips were monitored by using whole plant washes of a detergent mixture with an alcohol rinse. Plants were monitored for pest insects and damage through the season and were mapped at harvest.
