The field experiment was conducted during kharif 2016-17 to evaluation of botanical insecticides against pod borer on cowpea. Two rounds of insecticides were sprayed at fifteen days interval. The most effective treatment evaluated against pod borer was chlorpyriphos 20 EC@ 300g a.i. ha^-1 during first spray (1.97, 1.74 and 1.53 larvae /m² at 3, 5, and 7 days after spray, respectively) and second spray (1.51, 1.54 and 1.93 larvae /m² at 3, 5 and 7days after spray, respectively) followed by neem oil @ 2 % first spray (4.30, 4.08 and 3.52 larvae /m² ) second spray (3.00, 2.85 and 3.28 larvae /m² ) and NSKE @ 5 % during first spray (4.62, 4.18 and 3.81 larvae /m² ) second spray (3.12, 3.09 and 3.37 larvae /m² ) respectively. The maximum larval population was found in untreated plot. The highest green pod yield of cowpea was recorded in Chlorpyriphos 20 EC@300g a.i. ha^-1 (53.12 qha^-1 followed by neem oil @ 2% (43.53 qha^-1) and NSKE @ 5% (42.11 qha^-1) while lowest yield recorded in untreated control plot (32.16 qha^-1).
