Evaluation of efficacy of insecticide mixtures against the leaf eating caterpillar, Spodoptera litura was conducted at College of Agriculture, Vellayani, Thiruvananthapuram during 2017. The result revealed that no larva was recorded in the treatments lambda cyhalothrin 4.6 % + chlorantraniliprole 9.3 % ZC @ 0.50 mL L-1 and chlorantraniliprole 8.8 % + thiamethoxam 17.5 % SC @ 0.30 mL L-1 and flubendiamide 19.92 % + thiacloprid 19.92 % SC @ 0.50 mL L-1 treated plants after 5 days of spraying. Then from 7 seven days after spraying no larvae was recorded in the treatments lambda cyhalothrin 4.6 % + chlorantraniliprole 9.3 % ZC @ 0.50 mL L-1 and chlorantraniliprole 8.8 % + thiamethoxam 17.5 % SC @ 0.30 mL L-1 only and larval population was increased in flubendiamide 19.92 % + thiacloprid 19.92 % SC @ 0.50 mL L-1. The existing management practices with single insecticides are meagre to meet the demand. Hence the present findings of the experiment concluded that the use of ready-mix formulations lambda cyhalothrin 4.6 % + chlorantraniliprole 9.3 % ZC @ 0.50 mL L-1 and chlorantraniliprole 8.8 % + thiamethoxam 17.5 % SC @ 0.30 mL L-1 were found to be superior in managing the larval population of S.litura in cowpea.
