Efficacy of insecticides against insect pests of Chilli

Among different treatments, dimethoate 30 EC and sulphur 80 WDG were found effective against chilli sucking pests like thrips (1.71 & 1.85/3 leaves), mites (1.40 & 1.50/3 leaves) and aphids (1.54 & 1.59/3 leaves) by recording least population over control. However, bifenthrin 10 EC and fenazaquin 10 EC recorded higher population and found ineffective against thrips, mites and aphids. While, novaluron 10 EC and thiodicarb 75 SP were effective against fruit borers like Helicoverpa (0.70 & 0.73/plant) and Spodoptera (0.56 & 0.80/plant). Pooled data on yield indicated that significantly higher green chilli yield obtained in Sulphur 80 WDG @ 3g/l (2755 kg/ha) followed by dimethoate 30 EC (2598 kg/ha), phosphamidon 85 WSC (2431 kg/ha) and acephate 75 WP (2314 kg/ha). On contrary, significantly lower yield was noticed in fenazaquin 10 EC (1675 kg/ha) and bifenthrin 10 EC (1726 kg/ha).
