Bio-efficacy of newer insecticides against Spodoptera litura in soybean

Abstract

The experiments was conducted during kharif 2017 and 2018 at the farm of AICRP on soybean, VNMKV, Parbhani (Maharashtra) to evaluate the different newer chemical molecules against Spodoptera litura in soybean. The data revealed that chlorantraniliprole 18.5 SC@ 30 g a.i./ha was the most effective followed by spinetoram 11.7 SC @ 15 g a.i./ha. The next most effective emamectin benzoate 5 SG @ 11 g a.i./ha, flubendiamide 39.35 SC @ 48 g a.i./ha, indoxacarb 15.8 EC @ 30 g a.i./ha and lamda-cyhalothrin 4.9 CS @ 15 g a.i./ha which were at par with each other. chlorantraniliprole 18.5 SC and spinetoram 11.7 SC proved most safer treatments against natural enemies as compared to Emamectin benzoate 5 SG lamda cyhalothrin 4.9CS. The maximum yield was recorded in treatment chlorantraniliprole 18.5 SC followed by spinetoram 11.7 SC, emamectin benzoate 5 SG and flubendiamide 39.35 SC which were at par with each other.
