Nine molecules viz; imidacloprid 70% WG @ 50 g a.i. / ha, emamectin benzoate 5% SG @ 200 g a.i. / ha, lambda cyhalothrin 4.9% CS @ 300 g a.i. / ha, thiamethoxam 25% WG @ 200 g a.i. / ha, imidacloprid 17.8% SL @ 200 g a.i. / ha, indoxacarb 14.5% SC @ 500 g a.i. / ha, flubendiamide 20% WG @ 250 g a.i. / ha, chlorpyrifos 50% + cypermethrin 5% EC @ 1250 g a.i. / ha, Beta-cyfluthrin 8.49% + imidacloprid 19.8% OD @ 1250 g a.i. / ha were evaluated. Treatment chlorpyrifos 50% + cypermethrin 5% EC 1250 g a.i. / ha was found effectiveness against cotton pink bollworm and followed by beta-cyfluthrin 8.49% + imidacloprid 19.8% OD 1250 g a.i. / ha.
