The field study was conducted during 2018–19 with a rice variety, Moti, to evaluate the bio-efficacy of the pyridine group insecticide, flonicamid 50 WG alongside chlorpyrifos 19% ME, imidacloprid 17.8 SL, thiamethoxam 25 WG, and fipronil 5 SC against rice yellow stem borer, Scirpophaga incertulus Walker at BHU, Varanasi. Results showed that fipronil @ 75 g ai ha−1 was the most effective against the stem borer (2.8% dead hearts & 1.6% white ears/10 hills after the first and the second sprays, respectively) but the yield was higher in flonicamid @ 100 g ai ha−1 treated plots (44.81 q ha−1), it might be due to its role in enhancing the plant vigour to tolerate pest damage.
