A field trial was conducted in kharif seasons of 2011-2012 to study the efficacy of certain entomopathogens viz., Beauveria bassiana, Metarhizium anisopliae,Verticilium lecanii, Bacillus thuringiensis var. kurstaki @ 5 g/l along with standard check - Quinalphos 25 EC @ 1.5 g/L and Spinosad 45%SC @ 73 g a.i. /ha against lepidopteran defoliators. Bacillus thuringiensis @ 1013 spores/ha followed by B. bassiana @ 1013 spores/ha were the most effective treatments when applied as foliar sprays at 38, 41 and 45 days old crop. These treatments were effective in reducing the foliage feeder larval population. The highest grain yield was obtained also in the treatment, B. thuringiensis var. kurstaki (474.77 kg/ha). The lowest yield was recorded in the control (215.23 kg/ha) which was significantly inferior to the rest of the treatments.
