Abstract

Candidate insecticide sprays were compared for their efficacy against major insect pests of brinjal. Endosulfan 0.025 per cent was offective against leafhopper nymphs and valexon 0,037 por cent against adults. Dimethoate 0.025 per cent was effective against the grubs of spotted beetle and quinalphos 0.025 per cent against the adult beetles. Quinalphos 0.037 per cent was able to bring down hairy caterpillar population effectively. Effective control of Leucinodes as shoot borer was achieved with valexon while as fruit borer this species was effectively controlled by quinalphos at 0.05 per cent Quinalphos treated plots yielded more than those of other chemicals.
