The presentstudy has been undertaken to evaluate the pesticidal activity of crudemetabolites against major groundnut defoliator Spodoptera litura derivedfrom the fungal isolates resides in the leaflets of common garden weed Clerodendroninerme. A total of 75 isolates belong to Alternaria sp, Cladosporiumsp, Paecilomyces sp, Rhizopus sp, Tricoderma sp were isolatedfrom leaflets of garden weed Clerodendron inerme by surface washingmethod and the isolated fungi were grown in liquidmedia. Ethyl acetate extractwas prepared from the filtrate of the respective fungal organism and the pesticidalactivity was studied. Pesticidal activity of the metabolites extracted from Cladosporiumsp revealed distinct pesticidal activity against all the life stages of S.litura as dose dependent manner.
