With a view to evaluate bio-efficacy of different ready-mix insecticidesagainst thrips, Scirtothrips dorsalis in Bt cotton, an experiment was conducted under field condition at Anand Agricultural University, Anand during Kharif 2017-18. Among the six ready-mix insecticides evaluated, acephate 50% + imidacloprid 1.8% SP and thiamethoxam 12.6% + lambda-cyhalothrin 9.5% ZC were found more effective on the basis population of thrips, whereas fipronil 5% SC and buprofezin 15% + acephate 35% WP were mediocre in their effectiveness. The maximum seed cotton yield (2691 kg/ha) was recorded in treatment of acephate + imidacloprid followed by thiamethoxam + lambda-cyhalothrin (2645 kg/ha), fipronil (2621 kg/ha) and buprofezin + acephate(2598 kg/ha). The highest (1: 8.57) NICBR obtained with the treatment of thiamethoxam + lambda-cyhalothrin followed by acephate +imidacloprid (1: 7.44), buprofezin + acephate (1: 5.58) and fipronil (1: 4.73).
