Field experiment undertaken at AICRP on Potato, MARs, Dharwad during Kharif 2016 and 2017 to find out the effective botanical and bio-pesticide for managing insect pests of potato showed highest per cent protection over control against major insect pests of potato viz., potato shoot borer, aphids, leafhoppers, whitefly, thrips, mites and Spodoptera litura (52.77, 74.88, 68.04, 70.36, 73.94, 57.71 and 66.70 per cent, respectively) with the standard check, chlorpyriphos 20 EC @ 2.50 ml-1 across two kharif seasons. This was followed by NSKE @ 5 per cent (42.36 and 66.19 per cent), azadirachtin 3000 ppm @ 3.00 ml-1 (42.43 and 62.16 per cent) and neem oil @ 2 per cent (35.52 and 48.39 per cent) with respect to shoot borer and aphids. However in case of leafhopper, neem oil @ 2 per cent proved to be the next best treatment (62.92%), the second highest protection of 65.95 and 71.25 per cent, respectively was observed in Verticillium lecanii 2 × 108 cfu-1 @ 2 g-1 with respect to whitefly and thrips. The treatment, azadirachtin 3000 ppm @ 3.00 ml-1 recorded highest per cent protection over control in case of botanicalsmites (44.49%) and defoliator, S. litura (52.04%).
