Abstract:
Among the eight tested biopesticides, SlNPV 250 LE, B. bassiana 1% WP and aqueous bidi tobacco dust extract 2% found most effective and recorded minimum larval population of S. litura as well as per cent damaged groundnut plant. While, treatments of neem oil 1%, Btk 1% WP and M. anisopliae 1% WP were found moderately effective in reducing larval population and per cent damaged plant. Whereas, the treatments of azadirachtin 10000 ppm and N. rileyi 1% WP. Efficacy of biopesticides as reduction in S. litura population was SlNPV 250 LE > B. bassiana 1% WP > aqueous bidi tobacco dust extract 2% > neem oil 1% > Btk 1% WP > M. anisopliae 1% WP > azadirachtin 10000 ppm > N. rileyi 1% WP.
