Abstract: The present investigation entitled “Bio-efficacy of conventional insecticides against fall armyworm Spodoptera frugiperda (J E Smith)” was conducted at Instructional Farm of Post Graduate Institute, M.P.K.V., Rahuri during Rabi 2020-21.
The experiment consisted eight treatments viz., bifenthrin 10% EC @ 50 g a.i./ha, deltamethrin 2.8% EC @ 15 g a.i./ha, lambda cyhalothrin 5% EC 15 g a.i./ha, cypermethrin 10% EC @ 50 g a.i./ha, ethion 50% EC @ 500 g a.i./ha, fenvalerate 10% EC @ 75 g a.i./ha, profenofos 50% EC @ 500 g a.i./ha and untreated control. These treatments were evaluated in Randomized Block Design in three replications. Total three sprays of each insecticide were given at 10 days interval starting from the time when sufficient pest population was observed. Observations were recorded as number of larvae per 30 plants and per cent infestation of fall armyworm. Among all the tested insecticides, the treatment of profenofos 50% EC @ 500 g a.i./ha expressed its superiority over rest of the treatments disclosing itself to be the most promising treatment with mean larval population of 4.61 and per cent infestation of 9.77. The range of mean larval population for other treatments varied from 7.27 to 28.86 and that for per cent infestation varied from 12.52 to 46.04 per cent. The next treatments to follow profenofos 50%EC @ 500 g a.i./ha were lambda cyhalothrin 5% EC @ 15 g a.i./ha and cypermethrin 10% EC @ 50 g a.i./ha.
