Abstract: Two year (2015-16 and 2016-17) field experiment was conducted in Randomized block design with eight treatments (seven insecticidal treatments and untreated control) and three replications to know the bio-efficacy of some insecticides for the management of early shoot bore, Chilo infescatellus (Snellen) in Sugarcane. All the insecticidal treatments recorded significantly less ESB infestation (3.02 to 10.62 %); more NMC (77.62 to 81.17 thousand/ha) and cane yield (87.58 to 98.38 t/ha) as compared to the untreated control (17.05%, 74.69 thousand/ha and 81.25 t/ha, respectively). The chlorantraniliprole 0.4 % GR 22.5 kg/ha followed by fipronil 0.3% GR @ 25 kg/ha both at planting and 60 days after planting found to be the statistically at par and best as they recorded least ESB infestation (3.02 and 3.22 %, respectively) as well as maximum NMC (81.17 and 80.25 thousand/ha) and cane yield (98.38 and 96.84 t/ha). The flubendiamide 39.35% SC @ 125 ml/ha and chlorantraniliorile 18.5% SC @ 375 ml/ha both at 30 and 60 days after planting were statistically at par with each other and the next better treatment in reducing the Early shoot infestation, NMC and cane yield.
