Online published on 19 June, 2014. Abstract Totally 42 species belonged to 20 genera were recorded. A preliminary screening of all the species isolated from soils were made for antifungal (antagonistic) activity against Fusarium oxysporum, a known soil borne fungal pathogen. Among the species tested the Trichoderma harzianum inhibited the pathogenic fungus to the maximum both in dual culture and in food poisoning technique. Gas chromatography mass spectrum analysis of acetonitrile extract of the filtrate of T. harzianum revealed the presence of six compounds represents six major peaks. The peaks correspond with diethyl phthalate, tetradecanoic acid 9,12 – octadecadienoic acid (z, z), oleic acid, 1, 2 –benzene di oxylic acid, diisooctyl ester and squalene.
