Abstract

The bio-efficacy of some selected insecticides against fall armyworm, Spodoptera frugiperda (J. E. Smith) in maize ecosystem was evaluated at College of Agriculture, Raipur (C.G.). The results of investigation on bio-efficacy of insecticides showed in terms of effect of 1st, 2nd and 3rd spray on the percent reduction of insect population over control and it was resulted that, thiamethoxam 12.6% + lambdacyhalothrin 9.5% ZC@ 125 ml a.i.ha-1 was found superior, which was followed by indoxacarb 14.5% SC@ 750 ml a.i.ha-1.
