The field trial was conducted on management of shoot fly through seed treatments and also to study their phytotoxicity in rabi sorghum 2014-15. The results revealed that, imidacloprid 70 WS (5 g/kg) and on par with chlorpyriphos 20 EC (5 ml/kg) found superior over all treatments by recording 0.73 eggs/plant. Next best treatments were spinosad 45 SC (2 ml/kg) (0.97 eggs/plant), acetamiprid 20 SP (5 g/kg) (1.07 eggs/plant) and fipronil 5 SC (5 ml/kg) (1.17 eggs/plant). Imidacloprid 70 WS (5 g/kg) and chlorpyriphos 20 EC (5 ml/kg) recorded significantly least deadhearts (14.83% and 15.17%, respectively) followed by fipronil 5 SC (5 ml/kg) (18.28%). Spinosad 45 SC (2 ml/kg), acetamiprid 20 SP (5 g/kg) and emamectin benzoate 5 SG (5 g/kg) recorded 25.40, 24.06 and 23.71 per cent deadhearts respectively followed by 1 per cent neem oil (25.60%). Flubendiamide 480 SC (4 ml/kg) and untreated control recorded higher damage due to shoot fly (27.80%). Highest net returns among all the treatments was recorded in imidacloprid 70 WS (21357.14 ₹/ha) followed by chlorpyriphos 20 EC (5 ml/kg) (19981.75 ₹/ha).
