ABSTRACT

Spodoptera litura (Fab.) is a commonly encountered and economically important insect pest of Black Gram. Black Gram producers typically use botanicals as mixture with panchagavya to mitigate S. litura population. The compatibility and efficacy of commonly used botanicals extracts mixture were evaluated with panchagavya in vitro which include botanical extracts containing Cleistanthus collinue leaf extract (5%) combination with panchagavya @ 5%, neem oil 3% + panchagavya 5%, pungam oil 3%+ panchagavya 5%, Ocimum sanctum extract 5% + panchagavya 5%, Calotrophis gigantea extract 5%+ panchagavya 5% has been studied for the pest management. Leaf disc with no choice method performed in a laboratory using Black gram to determine the per cent mortality of botanicals extract mixture with panchagavya against S. litura. The results indicated that all binary mixtures recorded visibly the highest per cent mortality in Neem oil 3% + panchagavya 3% followed by Cleistanthus collinue Extract 5%+ panchagavya 5%, Pungam oil 3% + panchagavya 5% and Ocimum 5% extract + panchagavya 5%. The botanicals extracts mixture with panchagavya was found to show the maximum percentage mortality against S. litura
