Evaluation of insecticides against fall armyworm, Spodoptera frugiperda (J. E. Smith) in maize during kharif

Abstract

India has invaded by an insect pest, Fall Armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) during 2018 which has become a major threat by causing severe damage to maize. The goal of the present investigation was to evaluate different insecticides against fall armyworm. The results showed that at three and five days after two sprays, fall armyworm larval density and percent leaf damage was significantly lower among treatments viz., spinetoram 11.7 SC, chlorantraniliprole 18.5 SC and emamectin benzoate 5 SG compared with the untreated control. The cost economics also showed that they were economically viable insecticides.
