Abstract
Abstract The study was conducted on a sod farm in Thermal, Calif. Experimental design was a randomized complete block with 4 replications. Individual plot size was 100 sq ft. Liquid formulations were applied with a Solo knapsack sprayer using a hollow-cone nozzle at 32 psi, and a spray rate of 4 gal/1000 sq ft. Cutworm larval density was estimated by flooding 2 randomly selected 1 sq yd areas per plot. After 2-3 min the cutworms emerged to the surface and were counted. Pretreatment larval counts were taken on 28 Aug, after which treatments were applied. There was an average of 0.94 larvae/yd2 pretreatment. Posttreatment counts were taken on 1 Sep. Soil texture was sandy loam. Water was pH 7.2. Thatch was negligible (Vie inch). Average temperature during the study was 95°F. The plots were irrigated daily with 0.1 inch of water during the study. All treatments
