The pulses seed is caused by various seed borne fungal pathogen during storage condition. In the present in vitro investigation a comparative evaluation of antifungal activity of four plant leaf extract and chemical fungicides against major seed borne fungi associated with seeds of pulses viz. Aspergillus flavus, Aspergillus niger, Fusarium oxysporium, Rhizopus stolonifer and Alternaria alternate. The antifungal activities of four plant leaf extracts were compared with commercially available four chemical fungicides. The antifungal activity of plant leaf extracts viz. Datura inoxia Mill., Calotropis procera Aiton., Parthenium hysterophorus L. and Ipomoea carnea L.. The antifungal activities of Ipomoea carnea L. was found most mycelia growth of inhibition of these test fungi; rest of the plant extracts Datura inoxia Mill., Calotropis procera Aiton., Parthenium hysterophorus L. were found effective inhibition of mycelia growth of fungi. Four chemical fungicides viz. Mancozeb (Indofil M-45), Copper oxychloride (Blitox 50WP), Carbendazim (Bavistin 50WP) and Hexaconazole (Contaf 5 EC) were evaluated against seed borne test fungi. The Systemic fungicides Hexaconazole and Carbendazim was found most efficient inhibitor which completely inhibited the radial mycelia growth of seed borne fungi followed by non-systemic fungicide Mancozeb and Copper oxychloride. The plant extracts as a biofungicides can possibly be effort in the management of seed borne fungi by an ecofriendly way.
