Abstract
Abstract ‘Silver Queen’ corn was seeded in Rockdale soil on 10 Feb 1996. A randomized complete block design was employed to provide 4 replicates each for 4 treatments comprising a plot size of 4 rows, 30 feet long. Insecticide applications were initiated when 2-5% of the plants were infested with FAW. Whorl treatments were continued at approximately 7 d intervals beginning 30 Mar. Whorl applications were made with a shaker jar, 10 cm above the whorl. This jar was fitted with a screen mesh lid appropriate for granular flow. No phytotoxicity was observed with either product. Evaluations were conducted 24 hours after each treatment by extracting 5 plants from plot centers, storing in polyethylene bags and transporting to the laboratory. Each plant was dissected, larvae extracted and counted. FAW populations were not significantly reduced by any treatment as compared with untreated check plots.
