Abstract Treatments were tested for relative efficacy against cotton aphid in nonirrigated cotton planted 5 May at Stoneville, MS. Plots of 8 rows (40 inch centers) by 65 ft, separated by 15 ft alleys, were arranged in a RCBD with 4 replicates. All treatments were applied by a high-clearance spray machine equipped with a compressed air spray system. Total spray volume was 6 gal/acre at 5 mph and 35 psi using 2 TX10 nozzles/row. Plots within a replicate were sprayed consecutively with the boom rinsed twice and blown clear between plots. A pretreatment survey on 19 Jun indicated a moderate aphid infestation. Treatments were applied on 20 and 27 Jun. Efficacy was determined by counting aphids per square inch on leaves in the top and middle portions of 80 randomly chosen plants/treatment at 3 and 6 or 7 DAT.

Abstract Insecticides were evaluated for relative efficacy against cotton aphid in nonirrigated cotton planted 6 May at Stoneville, MS. Plots of 8 rows (40 inch centers) by 65 ft, separated by 15 ft alleys, were arranged in a RCBD with 4 replicates. All treatments were applied by a high-clearance spray machine equipped with a compressed air spray system. Total spray volume was 6 gpa at 5 mph and 35 psi using 2 TX10 nozzles/row. Plots within a replicate were sprayed consecutively with the boom rinsed twice and blown clear between plots. Treatments were applied on 6 Jul. Efficacy was determined by counting aphids per square inch on leaves in the top, middle, and bottom third portions of 40 randomlychosen plants 1 h before initial treatment and at 3, 7, and 14 DAT.
