Evaluation of efficacy of insecticide mixtures against the spottedpod borer, Maruca vitrata was conducted at College of Agriculture, Vellayani, Thiruvananthapuram during 2017. The result revealed that no larva was found in the treatment 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 treated plants after 5 days of spraying. Then from 7 seven days after spraying no larvae was recorded in the treatment lambda cyhalothrin 4.6 % + chlorantraniliprole 9.3 % ZC @ 0.50 mL L-1 only and less number of larvae was recorded in chlorantraniliprole 8.8 % + thiamethoxam 17.5 % SC @ 0.30 mL L-1 followed by beta cyfluthrin 8.91% + imidacloprid 19.81 % SC @ 0.40 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 formulation lambda cyhalothrin 4.6 % + chlorantraniliprole 9.3 % ZC @ 0.50 mL L-1 is found to be superior to control larval population in cowpea.
