Abstract: A field experiment was conducted during rabi/summer 2021-22 at Nagaral village of Ron taluka in Gadag district, Karnataka to know the incidence and to assess the field efficiency of different insecticide molecules against sucking insect pests. The experiment was laid out in randomized block design with 11 treatments replicated thrice. The crop was cultivated during 1^st January 2022 as per the recommended package of practices except the insect protection measures. Observations on population of sucking insect pests were recorded soon after appearance on the crop from 15 to 75 days after sowing at fortnightly interval. Number of sucking insect pests were counted from three leaves (one each from top, middle and bottom canopy of crop) in each plant and three spots in each field, each spot consists of five plants and mean number of sucking insect pests per three leaves was recorded. Percent reduction over control was calculated and data was subjected to one-way ANOVA and Duncan’s Multiple Range Test. Result indicated that lowest mean population and highest reduction in the population of sucking insect pets was recorded in seed treated with cyantraniliprole 19.8% + thiamethoxam 19.8% @ 10 ml/kg seed followed by seed treated with thiamethoxam 30 FS @ 10 ml/kg seed, seed treated with imidacloprid 600 FS @ 10 ml/kg seed.
