Corn test plots were each ca. 30 acres grown under center pivot irrigation. Treatments were applied by a Cessna 188 Husky with a 44 ft wingspan. The spray boom was equipped with D-1245 nozzles calibrated to deliver 2 gal water per acre at 28 psi at 120 mph. Test 1 treatments were applied 24 Jul. Test 2 treatments were applied 1 Aug. Efficacy was determined by comparing the no. of plants infested with WBC larvae before treatment to the no. of infested plants after treatment (larvae in the ear tips).
