Abstract

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 hal-1).
