Bioefficacy of granular insecticides against fall armyworm, Spodoptera frugiperda (JE Smith) in maize

Abstract

To study the efficacy of granular insecticides against fall armyworm in maize, an experiment was carried out at three different locations i.e., Entomology Farm, BACA, AAU, Anand, Agriculture Research Station, AAU, Sansoli and Main Maize Research Station, AAU, Godhra during Kharif, 2019. Different eight granular insecticides were evaluated against fall armyworm in maize. Results revealed that whorl application of chlorantraniliprole 0.4% GR and fipronil 0.6 % GR @ 20 kg/ha, first at appearance of fall armyworm and second after 15 days were found effective as it recorded lower larval population, plant damage and cob damage and incurred higher straw and grain yield.
