In vitro antifungal potency of some plant extracts against Fusarium oxysporum

Bindu Sharma, Padma Kumar

Abstract


In an approach towards the development of ecofriendly antifungal compounds for controlling plant diseases caused by Fusarium oxysporum, different extracts of three weed plants, namely, Capparis decidua, Lantana camara and Tridax procumbens, were tested for their antifungal potential. The spore germination/spore counting technique was followed for the evaluation of the antibiotic properties of the extracts at three different concentrations. Results revealed that the free flavonoids and sterols of T. procumbens (flower) and bound flavonoids of C. decidua (fruit and stem) totally inhibited spore germination of the fungi (100%). The antifungal
components from these plants could be used in developing novel fungicides (biopesticides) for the diseases caused by F. oxysporum (plant pathogen).
Key words: Capparis decidua, Fusarium oxysporum, Lantana camara, percentage spore inhibition, Tridax procumbens
