    Abstract

    Experiments in resistant and susceptible sorghum genotypes during the post-rainy season from 1986 to 1988 at ICRISAT, India showed that foliar applications of cypermethrin applied by ‘Electrodyn’ sprayer were significantly superior to high-volume and low-volume sprays. Effective control of shoot fly and higher grain yields were obtained when the spray was initiated 6 days after crop emergence. The lowest dosage of cypermethrin (22.5 g a.i. ha−1) gave shoot fly control and grain yield increases similar to those of the higher dosages (33.75 and 45 g a.i. ha−1). Chemical control of shoot fly had the greatest effect on shoot fly infestation and increases in grain yields in susceptible genotype CSH 1, followed by the local M35-1 and resistant ICSV 707. Cypermethrin applied by Electrodyn was significantly superior to the recommended practice of carbofuran soil application and high-volume spray of endosulfan in reducing shoot fly damage in all the three genotypes. The main effect of cypermethrin foliar application was in the reduction of shoot fly oviposition that resulted in less damage, indicating either an oviposition deterrent effect or death of the adults before oviposition.
