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%. [ABSTRACT FROM AUTHOR]

Among the various insecticides evaluated for their field efficacy against sucking pests of Indian bean, the treatments of thiamethoxam 25WG at 0.025%, acetamiprid 20SP at 0.004% and buprofezin 25SC at 0.05% were found to be the most effective against Aphis craccivora Koch, Empoasca kerri Pruthi and Bemisia tabaci Gennadius. While, thiacloprid 21.7SC at 0.012% emerged as the moderately effective. Emamectin benzoate 5SG at 0.002%, indoxacarb 14.5SC at 0.007%, lambda-cyhalothrin 5SC at 0.005% and novaluron 10EC at 0.01% were found to be less effective. [ABSTRACT FROM AUTHOR]

A field experiment to evaluate some IPM modules against major pests viz., Aphis gossypii, Myzus persicae, Bemisia tabaci and their natural enemies viz., coccinellids and spiders occurring in king chilli Capsicum chinense Jacquin was carried out during rabi (2014-16) at Jorhat, Assam. The results revealed that module M2 with seedling root dip treatment with imidacloprid 17.8 SL @ 40g a.i./ha + growing of border crop (okra)+ spraying of imidacloprid 17.8SL @ 40g a.i./ha at 20 days after transplanting at 15 days interval is the most effective in suppressing aphids and whitefly followed by lambdacyhalothrin instead of imidacloprid in both the seasons. The insecticidal treatment modules had a significant effect on the pest and the viral diseases, thereby increasing the yield, with maximum yield obtained in module M2 (3564.44 kg/ha) and with a maximum cost-benefit ratio of 1: 4.85.
