A field experiment was conducted with the title Management of insect pest of sorghum in kharif season. In Kharif season 2018 and 2019 at Sorghum Research Station, VNMKV Parbhani (MS) India. Management of shoot pests of sorghum Randomized Block Design (RBD) with seven treatments and three replications were used. In management of shoot pests different IPM components used against shoot fly dead hearts at 28 DAE Pooled data kharif 2018-19 and 2019-20, all the treatments significantly at par with each other except untreated control. Significantly minimum per cent of dead hearts were recorded in the treatment T4 [Seed treatment with imidacloprid @ 3g ai/kg seed+ Bacillus thuringiensis 20 ml/10 lit. of water at 35 DAE] (8.61 %) and all the treatments are statistically at par with each other except untreated control.
