A field trial was conducted during Rabi, 2015-16 and Kharif, 2016 cropping seasons. An attempt was made to find out the cost effective management schedule to minimize the crop loss. Seven insecticides viz., Fipronil5% SC@800ml/ha, Indoxacarb 14.5% SC@400ml/ha, Acephate 75 SP@0.1%, Spinosad 45%SC@160ml/ha, Imidacloprid 17.8% SL@0.003%, Fenvalerate 20EC@500ml/ha and Carbofuran 3G@30Kg/ha were evaluated against vector activity to reduce the leaf curl disease incidence. The minimum disease incidence was recorded to the extent of (19.26 %) and (44.38 %) coupled with highest fruit yield of 87.78 q/ha and 65.94 q/ha in the treatment T7 having three times soil application of Carbofuran 3G @ 30 Kg/ha at an interval of ten days during both Rabi, 2015-16 and Kharif, 2016 cropping seasons, respectively. Maximum disease incidence was found in Kharif season. Minimum disease incidence was recorded during Rabi crop season in comparison to Kharif crop season. Infection by chili leaf curl disease complex adversely affected yield attributing characters during Kharif season as compared to Rabi season. Highest cost-benefit ratio of 1:13.80 and 1:11.60 was obtained by the application of Imidacloprid17.8 % @ 0.00 3 % during both Rabi and Kharif seasons, respectively.
