Evaluation of Different Insecticides against Spotted Pod Borer, M. vitrata Infesting Vegetable Cowpea

A field experiment was conducted at Anand Agricultural University, Anand during kharif 2021 to assess the bio-efficacy various insecticides against spotted pod borer, Maruca vitrata infesting vegetable cowpea of the nine evaluated insecticides chlorantraniliprole 18.5% SC, emamectin benzoate 5% SG were found the most effective in reducing the incidence of M. vitrata. However, spinetoram 11.7% SC and spinosad 45% SC were found mediocre in their effectiveness. Maximum (76.33 q/ha) green cowpea pod yield was recorded from the plot treated with chlorantraniliprole which was at par with emamectin benzoate (75.50 q/ha). The highest ICBR returns were obtained in the treatment of emamectin benzoate (1: 11.48) followed by chlorantraniliprole (1: 8.67), spinetoram (1: 5.20) and spinosad (1: 4.92).
