Bio-efficacy of different insecticides against fall armyworm, Spodoptera frugiperda (J.E. Smith) on Maize

Abstract

The present field experiment were conducted to estimate “Bio-efficacy of different insecticides against fall armyworm, Spodoptera frugiperda (J.E. Smith) on Maize” under field condition during Kharif season of 2019 at research farm of Oilseed Research Station, Latur (Maharashtra, India). The observations were recorded on total number of live S. frugiperda larvae per 25 plants on one day before spray and three, seven days and fourteen days after the spray. The treatments of different insecticides viz., Chlorantraniliprole 18.5 SC @ 0.005 per cent, Emamectin benzoate 5 WG @ 0.002 per cent, Spinetoram 11.7 SC @ 0.011 per cent, Lambda Cyhalothrin 5 EC @ 0.025 per cent, Chlorantraniliprole 9.3 + Lambda Cyhalothrin 4.6 ZC @ 0.008 + 0.002 per cent and Thiomethaxam 12.6 + Lambda cyhalothrin 9.5 ZC @ 0.003 + 0.002 per cent were evaluated against S. frugiperda and revealed that Spinetoram 11.7 SC @ 0.011 per cent was found most effective treatment in reducing the population of S. frugiperda followed by Emamectin benzoate 5 WG @ 0.002.
