Abstract: A field trial was conducted during kharif 2019 cropping seasons. An attempt was made to find out the effective management practice through application of agrochemicals to minimize vector activites &the crop loss. Three bio rational molecules viz., Imidacloprid 17.8 SL @ 1.0 ml/3liter water, Acetamiprid 20% SP @1.0 gm/ liter water and KEM (Immunity Builder) @2.0 ml/ liter were sprayedat 15 day interval and were evaluated against vector activity to reduce the leaf curl disease incidence. The minimum disease incidence was recorded to the extent of (27.25%) coupled with highest fruit yield of 63.13 q/ha in the treatment T2 having two spraying of Acetamiprid 20% SP @1.0 gm/ liter water at an interval of fifteen days during Kharif 2019 cropping season. Maximum disease incidence (32.25%) in control with lowest yield (54.23/ha). Infection by chili leaf curl disease complex adversely affected yield attributing characters during Kharif season. Highest cost-benefit ratio of 1:11.49 was obtained by two spraying of Acetamiprid 20% SP @1.0 gm/ liter water during Kharif crop season.
