Abstract:
Studies on bio-efficacy of seven insecticides against fall armyworm, Spodoptera frugiperda revealed that spinetoram 11.7% SC @ 30 ml a.i./ha was found most effective insecticide, which recorded the highest reduction in larval population i.e., 76.30% and 86.28% after first and second sprays, respectively followed by Chlorantraniliprole 18.5% SC @ 27.75 ml a.i./ha which recorded 71.67% and 82.30% reduction in larval population after first and second sprays, respectively. The overall mean population of S. frugiperda was recorded minimum in Spinetoram 11.7% SC having 0.41 larva/plant after first spray and 0.31 larva/plant after second spray followed by Chlorantraniliprole 18.5% SC having 0.49 larva/plant after first spray while 0.40 larva/plant after second spray.
