A field experiment was carried out at Integrated Farming Systems Research Station, Karamana, on rice variety Uma (MO 16) during Kharif 2017, to study the impact of new generation granular insecticides on rice yellow stem borer, Scirpophaga incertulas (Walker). Results showed that in terms of efficacy against stem borer, on the basis of overall performance of granular insecticides, fipronil 0.3G at 10 and 20 kg ha-1 was found to be more effective and superior among other granules in reduction of stem borer infestation to minimum of 1.84 and 2.13 per cent of dead hearts (DH) and 5.63 and 4.07 per cent of white ear heads (WEH) respectively. This was followed by Cartap hydrochloride 4G at 25 and 50 kg ha-1 with 4.61 and 4.63 per cent of DH; 7.00 and 6.40 per cent of WEH respectively. The untreated control recorded 9.61 per cent of DH and 12.41 per cent of WEH respectively. Chlorantraniliprole 0.4 G at 10 kg ha-1 found to be the least effective one with 5.46 and 9.23 per cent of DH and WEH respectively.
