A field experiment with 12 treatments was conducted to investigate the efficacy of different insecticides and bio-pesticides against leafhopper on Bt cotton. Two sprays of different insecticides and biopesticides were applied when the pest population attained economic threshold level. Flonicamid 50% WG @ 150 g/ha recorded the maximum reduction of leafhopper population (69.60%), followed by pyriproxyfen 10% EC (68.34%) and diafenthiuron 50% WP @ 600 g/ha (66.83%).
