Online Published on 04 January, 2024. Abstract Among the various insecticides evaluated for their field efficacy against pod borers of Indian bean, the treatment of emamectin benzoate 5SG at 0.002%, indoxacarb 14.5SC at 0.007% and lambdacyhalothrin 5SC at 0.005% were found to be most effective against Helicoverpa armigera (Hubner) and Maruca vitrata Geyer. While, thiacloprid 21.7SC at 0.012% and novaluron 10EC at 0.01% were moderately effective. The least pod damage was observed with emamectin benzoate 5SG at 0.002% (13.16%) which was at par with indoxacarb 14.5SC at 0.007% (14.16%) and lambdacyhalothrin 5SC at 0.005% (16.33%). Maximum pod yield (21.75 q/ ha), increase in yield over control (95.76%) and % of avoidable loss (48.91%) was observed with emamectin benzoate 5SG at 0.002%.
