A field experiment was carried out to evaluate the efficacy and phytotoxic effects of Tetraniliprole 200 g l-1 SC (Vayego 200 SC) for the management of fall armyworm Spodoptera frugiperda (J.E. Smith) on maize. Among different dosages of Tetraniliprole 200 g l-1 SC (Vayego) insecticide the cumulative effect of two sprays against the fall armyworm on maize revealed that the treatment T4 Tetraniliprole 200 g l-1 SC (Vayego) @ 250 ml ha-1 was found to be highly effective against fall armyworm by recording highest overall larval reduction (81.04%) over control, lowest per cent cob damage (30.57) followed by T3-Tetraniliprole 200 g l-1 SC (Vayego) @ 200 m ha-1 with a reduction of 77.82 per cent as compared to dimethoate 30% EC @ 660 ml ha-1 check recorded 43.59 per cent larval reduction. The tetraniliprole at both the concentrations had not shown any phytotoxic symptoms, was safe to natural enemies and recorded highest grain yield of 6425 kg ha-1 and 5870 kg ha-1, respectively.
