Abstract: Present study was conducted to evaluate the fungicidal property of methanolic extracts of some indigenous plants of Karachi such as Hibiscus rosa-sinensis (leaves), Thespesia populnea (leaves, stem and fruit), Withania somnifera (leaves and stem), Solanum surattense (shoot) and Melia azedarach (fruit) against common soil-borne phytopathogens viz., Macrophomina phaseolina, Rhizoctonia solani and Fusarium oxysporum by using food poison technique. Among the eight methanolic extracts of tested parts of plants, seven showed antifungal activity, of which T. populnea leaves and S. surattense shoots inhibited growth of all three test pathogens. Leaves of H. rosa-sinensis did not exhibit antifungal activity. T. populnea (leaves and stem), W. somnifera (stem) and M. azedarach (fruit) suppressed growth of Rhizoctonia solani by 100%. T. populnea leaves and M. azedarach fruit inhibited growth of M. phaseolina by 100% and 82%, respectively T. populnea leaves inhibited 99% mycelial growth of F. oxysporum. It is concluded that the methanolic extracts of the tested indigenous plants contain natural fungicidal compounds, which can be used for the control of common soil-borne pathogens.

Key words: Soil-borne fungi, Antifungal activity, Methanolic extracts, Indigenous plants.
