ABSTRACT
Fusarium spp. constitute a complex group of destructive soil borne pathogens. Aqueous extracts of ten botanicals were evaluated for their antifungal properties against Fusarium oxysporum. Among the different plant extracts tested, the methanol extracts of the flowers of Q. indica and the leaves of M. micrantha at 5% concentration exhibited 89.49 and 88.90 per cent mycelial growth inhibition of the fungal pathogen respectively. Phytochemical screening of the flowers of Q. indica showed the presence of flavonoids, alkaloids, terpenes, phenolics, tannins, steroids, coumarins and glycosides whereas the leaves of M. micrantha recorded the presence of flavonoids, alkaloids, terpenes, phenolics, coumarins and glycosides. The methanol extract of flowers of Q. indica upon column chromatography yielded a white crystalline powder. Analysis of spectroscopy data revealed the compound to be 1-methoxy 2-tert- butyl- 4- propyl-6- methylbenzene. Thus, the present study revealed the antifungal potential of the weed plants viz., Q. indica and M. micrantha against F. oxysporum which can be utilized as ideal substitutes for synthetic fungicides.
