An experiment was conducted to evaluate the efficacy of ten insecticides against castor shoot and capsule borer Conogethes punctiferalis. Pooled efficacies of treatments revealed that combination treatment of chlorantraniliprole 18.5SC + azadirachtin 1EC @ 0.3 ml l-1 + 1 ml l-1 was recorded as the most effective treatment which exhibited highest efficacy against C. punctiferalis (77.26% reduction over control) followed by chlorantraniliprole 18.5SC @ 0.3 ml l-1 which recorded 73.46% reduction over control. The highest yield was obtained with chlorantraniliprole 18.5SC (0.0055%) + azadirachtin 1EC (0.01%) @ 0.3 ml l-1 + 1 ml l-1 (2369 kg ha-1).
