Abstract

Study on laboratory efficacy of different insecticides against Spodoptera frugiperda (J. E. Smith) were carried out at Biocontrol Research Laboratory, Department of Entomology, Junagadh Agricultural University, Junagadh. The result showed that the treatments of spinetoram 11.7 EC, 0.012%, emamectin benzoate 5 SG, 0.0025% and thiodicarb 75 WP, 0.075% were found the most effective against S. frugiperda as they recorded cent per cent mortality after 5 days of treatment under laboratory condition. However, it was followed by chlorantraniliprole 18.5 SC, 0.005%, spinosad 45 SC, 0.013% and chlorantraniliprole 9.3% +lambda-cyhalothrin 4.6% ZC, 0.006% in which mortality of 85.56, 81.11 and 70.00% was recorded after 5 days, respectively.
