The present study entitled, Evaluation of different insecticides for seed treatments against Sorghum shoot fly Atherigona soccata Rondani was carried out during Rabi 2020-21. Observations were made on plant population per cent, seedling vigour, days required to 50% flowering, shoot fly eggs per five plants, shoot fly dead hearts, height and yield. The results of experiment revealed that, among the seven treatments at 28 DAE, the seed treatments with Thiamethoxam 30 FS @ 10 ml/kg seed (19.76%), Cyantraniliprole 19.8% + Thiamethoxam 19.8% FS (21.00%) and Imidacloprid 17.8 SL (21.46%) recorded the lowest dead hearts caused due to shoot fly indicating that treatments were effective in controlling shoot fly infestation. The maximum ICBR 1:43.80 was obtained in seed treatment with Imidacloprid 17.8 SL @ 3 ml/kg of seeds followed by Fipronil 5 SC @ 5 ml/kg of seed treatment (1:41.69) and Thiamethoxam 30 FS @ 10 ml/kg of seeds (1:37.43).
