abstract
Study was conducted to determine the bio-efficacy of seven insecticides against sucking insect pests viz., thrips (Scirtothrips dorsalis Hood) and whitefly (Bemisia tabaci Gennadius) in chilli variety GVC-111 during kharif and rabi 2013. Among the different insecticides, imidacloprid 17.8 SL @ 0.005% (5.12 thrips/3 leaves and 0.96 whiteflies/leaf), acetamiprid 20 SP 0.004% (0.58 whiteflies/leaf) and triazophos 40 EC @ 0.04% (1.09 whiteflies/leaf) found most effective. Highest green chilli fruit yield (110.25 q/ha) was harvested from crop treated with imidacloprid followed by thiamethoxam (106.55 q/ha), triazophos (103.79 q/ha) and acetamiprid (102.91 q/ha). The highest Incremental Cost Benefit Ratio (1:23.17) was registered in imidacloprid followed by thiamethoxam (1:20.45), acetamiprid (1:19.60) and triazophos (1:17.69).
