Abstract :

The studies on the efficacy of newer insecticides as foliar revealed that imidacloprid 17.8 SL @ 40 g a.i./ ha was the most effective treatment indicating reduction in population of leafhoppers, aphids, whiteflies and thrips was 89.9, 93.1 , 91.0 and 90.65 per cent , respectively and recorded maximum fruit yield of 52.2 q/ha with 97.72 per cent increase in fruit yield over untreated control. It was followed by imidacloprid 17.8 SL @ 15 g a.i./ha, thiamethoxam 25 WG, acetamiprid 20 SP and fipronil 5 % SC. All the treatments, except spinosad 45 SC were effective in controlling sucking pest population in okra and all the treatments were observed to be significantly superior over untreated control.
