Abstract:
The present paper describes the antifungal activity of some plant extracts on the growth of Fusarium oxysporum and Meloidogyne incognita. The leaves of botanical viz. Polyalthia longifolia, Leucaena leucocephala, Butea monosperma, Alstonia scholaris, Psidium guajava, Cassia fistula, Grevillea robusta Jatropha curcas, Peltophorum pterocarpum and Ailanthus altissima was tested in vitro and screened to study the antimicrobial activity and to determine the zone of inhibition of extracts on Fusarium oxysporum and J₂ of M. incognita released from the eggs. The number of J₂ M. incognita hatching from eggs were found significantly reduced as compared to the control, however P. guajava were found the most effective extracts against hatching of juvenile with 100% inhibition. Further, on testing the fungus with the botanicals, Polyalthia longifolia extract showed the best inhibitory effect against F. oxysporum with 37.73% reduction as compared to the control.
