Tank mixing Provado with an organosilicant surfactant substantially improved cotton aphid, Aphis gossypii Glover, control (»45%) and cottonseed yields (»50 lbs.) versus Provado alone under drought-stressed conditions (»4 weeks). In a late-season boll weevil, Anthonomus grandis grandis Boheman, trial, Karate 2.08CS provided better control than Karate 1EC after three applications over a 12-day period. Overall, weevil control was best obtained with Baythroid 2EC, Decis 1.8EC, Karate 1EC (0.03 lbs. AI/A), and Karate 2.08CS (0.025 and 0.03 lbs. AI/A). Karate 2.08CS (0.025 lbs. AI/A) provided longer residual control (7-day interval on 25 September) than the older Karate 1EC (0.025 lbs. AI/A).
