Abstract:

The Diamondback moth (Plutella xylostella) shows resistance to every group of conventional insecticide and unable to reduce the population and their damage. New molecules are crucial tool for their management. The efficacy of insecticides were evaluated against P. Xylostella with treatments viz. spinosad 45% SC @ 185ml, emamectin benzoate 5% SG @ 250g, indoxacarb 14.5 SC @ 500ml, chlorantraniliprole 18.5 SC @ 150ml, Cyantraniliprole 10% OD @ 600g, neem oil 32% EC @ 1.5L and flubendiamide 20% WG @ 100g commercial formulation dosage ha-1. The efficacies were calculated by Henderson and Tilton method. After five days of spray, maximum efficacy was obtained from chlorantraniliprole which was at par with, Cyantraniliprole, emamectin benzoate, flubendiamide and spinosad, these were significantly superior over indoxacarb and neem oil. After ten days of spray, maximum efficacy was again with Cyantraniliprole which was at par with chlorantraniliprole and these were significantly superior over rest of the treatments. Chlorantraniliprole and cyantraniliprole may be admissible in to IPM tool to combat P. Xylostella by dint of their efficiency.
