Abstract

Chemical control is a common practice by the farmers to manage fall armyworm (Spodoptera frugiperda) in corn since its invasion in India from 2018. Thus, the main purpose of the work was to evaluate for the first time the field efficacy of a recently introduced novel insecticide i.e., broflanilide against fall army worm (FAW) during winter 2019-20 and kharif 2020. Broflanilide 30 SC @ 60 ml ha-1 resulted highest overall mean mortality (86.15 and 87.02%) in larval population of FAW over untreated control. It was significantly at par with its next lower dose of 50 ml ha-1 (83.13 and 85.06%) followed by chlorantraniliprole 18.5 SC (79.58 and 81.30%) and emamectin benzoate 5 SG (78.75 and 81.81%). Statistically at par remarkable lower damage and attack intensity with considerable higher yield occurred in broflanilide (60 and 50 ml ha-1), chlorantraniliprole (200 ml ha-1) and emamectin benzoate (300 g ha-1). So, broflanilide @ 50-60 ml ha-1 could be recommended as another alternative insecticide to manage S. frugiperda in corn.
