Field efficacy of newer insecticides viz., Fipronil 0.3%GR, Chlorantraniliprole 0.4%GR, Cartap hydrochloride 50% SC, Cartap hydrochloride + Fipronil 4% + 0.5% CG, Fipronil 5% SC, Chlorantraniliprole 18.5% SC and Flubendiamite 9.35% SC, and untreated control were evaluated against yellow stem borer (Scripophaga insertulas) in rice during kharif 2020-21. The result showed that the Cartap hydrochloride + Fipronil 4% + 0.5%CG was proved to be best and recorded minimum infestation of 3.36% DH and 2.68% WE, followed by Fipronil 0.3%GR with 3.93% DH and 3.21% WE. Rests of the treatments were next level best over control. Whereas, the maximum infestation of 11.61% DH and 10.45% WE was recorded in control plot. The highest yield of 50.70 q/ha and net return of Rs. 61120.00/ha was obtained from Cartap hydrochloride + Fipronil 4% + 0.5%CG treated crop followed by Fipronil 0.3%GR with 45.75 q/ha and Rs.41863.76/ha, respectively. Whereas, due to cost of treatment, Fipronil 0.3%GR was recorded highest Benefit Cost Ratio (1:9.30) followed by Fipronil 5% SC (1:8.24) and remaining treatments. Minimum yield (38.40 q/ha), net return (Rs. 6402.12/ha) along with BC ratio (1:1.58) was found in Cartap hydrochloride 50%SP.
