- Abstract
The present study has been undertaken to evaluate the pesticidal activity of crude metabolites against major groundnut defoliator Spodoptera litura derived from the fungal isolates resides in the leaflets of common garden weed Clerodendron inerme. A total of 75 isolates belong to Alternaria sp, Cladosporium sp, Paecilomyces sp, Rhizopus sp, Tricoderma sp were isolated from leaflets of garden weed Clerodendron inerme by surface washing method and the isolated fungi were grown in liquid media. Ethyl acetate extract was prepared from the filtrate of the respective fungal organism and the pesticidal activity was studied. Pesticidal activity of the metabolites extracted from Cladosporium sp revealed distinct pesticidal activity against all the life stages of S. litura as dose dependent manner.
