abstract
Interest in potential of botanical extracts against phytopathogenic fungi has increased due to some negative effects associated with the chemical fungicides. The present study was performed to determine antifungal activity of 27 plants (belonging to 26 genera and 14 families) collected from different places to Karnataka against two phytopathogenic fungi namely Colletotrichum capsici and Fusarium oxysporum f.sp. zingiberi by poisoned food technique. All extracts were efficient in inhibiting test fungi but to a varied extent. Marked inhibitory activity of extracts was observed against C. capsici when compared with F. oxysporum f.sp. zingiberi. Out of 30 extracts, 19 and 11 extracts exhibited an inhibitory activity of 50% and higher against C. capsici and F. oxysporum f.sp. zingiberi respectively. Highest and least inhibition of both fungi was displayed by Curcuma aromatica and Vanda roxburghii respectively. The botanical extracts used in this study appear to be promising agents capable of inhibiting phytopathogenic fungi. Further studies on inhibitory activity of these extracts against test fungi are to be carried in field conditions.
