Abstract: Selected insecticides viz. Azadirachtin 10000 ppm, Chlorantraniliprole 18.5 SC, Cyantraniliprole 10.26 OD, Flubendiamide 39.35 SC, Indoxacarb 14.5 SC, Lambda cyhalothrin 5 EC, Novaluron 10 EC were evaluated for their effectiveness against tomato fruit borer by conducting field trial at Post Graduated Institute, MPKV, Rahuri during the year 2018. Three sprays of each insecticide were applied at the occurrence of the pest. The result revealed that lowest larval population (0.59 larva/plant) of H. armigera was recorded in treatment of chlorantraniliprole 18.5% SC. Indoxacarb 14.5% SC (0.73 larva/plant) was the next promising treatment which was followed by flubendiamide 39.35% SC exhibiting 0.80 larva/plant. Treatments viz., cyantraniliprole 10.26% OD, lambda cyhalothrin 5% EC and azadirachtin 10000 ppm found to be moderately effective against H. armigera and recorded larval population ranging from 0.93 to 1.15 larvae per plant. Novaluron 10% EC was the least effective, with maximum (1.19 larvae/plant) population of H. armigera.
