Pigeon pea is one of the important pulse crops in India. Among the different production constraints, infestation by insect pests is of major concern. In present study, six insecticides were evaluated in sequential schedules to manage pod borers and blister beetle which were major pests. Spray of chlorantraniliprole 18.5 SC@ 30g a.i./ha followed by indoxacarb 15.8 EC @ 73ga.i./haat 15 days interval was found to be effective in reducing spotted pod borer, Maruca vitrata larva and two sprays of dimethoate 30 EC@ 600g a.i./ha was found to be effective in reducing adult blister beetle population. Least pod damage (cumulative of M. vitrata and Melanagromyza obtusa) was observed with chlorantraniliprole 18.5 SC@ 30g a.i./ha followed by dimethoate 30 EC @ 600g a.i./ha at 15 days interval. Based on cost benefit ratio, two sprays of acephate 75 SP@ 750g a.i./ha at 15 days interval was found to be superior with C: B of 1: 9.38.
