Talent 40 SC and Tender 10 EC cause the highest 97.9% mortality in Aphids while the lowest was caused by Confidor 20SL. The efficacy of Tender 10EC against Jassids was higher than other insecticide that was about 85.9%. In case of white flies the highest mortality was caused by Buster 20SP, that was about 86.9 percent and the lowest mortality was caused by Crown 200SL which was 82.9%.
