This test was conducted in a commercial cotton field grown near Lubbock, TX. The field was on 40-inch rows, and was irrigated using furrow irrigation. Plots were 4-rows wide × 50 ft in length. Insecticides were applied with a CO2 pressurized hand-boom sprayer calibrated to deliver 10 gpa through TX-6 hollow cone nozzles (2 per row) at 40 psi. Insecticides were applied to all four rows of each plot. Treatments were evaluated by collecting 5 or 10, mid canopy leaves per plot and returning these to the laboratory where the mites were removed onto a liquid detergent coated glass plate with a mite brush. Mite eggs, larvae and adults were counted from the entire glass plate. Data were analyzed using ANOVA and means were separated using an F-protected LSD (P ≤ 0.05).
