Abstract: A field experiment was conducted during rabi 2017-18 to evaluate different insecticides against aphid, Aphis gossypii Glover infesting isabgul at Sardarkrushinagar. Among them, flonicamid 50WG (0.015%) was proved as most effective insecticide (0.76 aphid index) for the management of isabgul aphid and it was followed by the treatments of thiamethoxam 25WG (0.0084%) and imidacloprid 17.8 SL (0.005%) which registered 0.90 and 0.97 aphid index, respectively at seven days of second spray. Flonicamid 50WG (0.015%) had obtained the highest seed yield of isabgul (1012 kgha^-1) but it was statistically at par with thiamethoxam 25WG (0.0084%) (918 kgha^-1).
