Experiment was conducted at Entomology Block of agriculture research cum instructional farm, I.G.K.V., Raipur, Chhattisgarh in year 2014-2015 to evaluation the bioefficacy of granular insecticide molecules against pink stem borer. The results revealed that the minimum leaf injury rating was recorded with carbofuran (3.00) which was at par with flubendiamide (3.23) followed by thiamethoxam (3.43), emamectin benzoate (3.57), rynaxypyr (4.03) and cartap hydrochloride (4.17) treated plots. The highest leaf injury mean was recorded 4.20 with fipronil. The minimum per cent of dead heart damage was recorded with carbofuran 36.67% which was at par with flubendiamide 43.33% followed by rynaxypyr 45.50%, thiamethoxam 46.67%, emamectin benzoate 50.0%, and cartap hydrochloride 56.67% treated plots. The highest per cent dead heart damage was recorded with fipronil 60.0%.Thegrain yields was also significantly highly influenced by carbofuran 3 G followed by flubendiamide 20 WG, thiamethoxam 25 WG, emamectin benzoate 5 SG and cartap hydrochloride 4 G, rynaxypyr 0.4% G and fipronil 0.3% G.
