Antifungal Activity in Urginea indica Kunth. (Asparagaceae)

Abstract

Aqueous extract of Urginea indica kunth. (Udupi acccession) was screened for antifungal activity against Fusarium oxysporum, Sclerotium rolfsii, Magnaporthe orzae, Aspergillus flavus, Alternaria alternata, Aspergillus niger and Fusarium moniliformae by poisoned food technique. The results confirmed Urginea indica extracts showed very significant antifungal activity against Fusarium oxysporum and showed significant inhibition for Sclerotium rolfsii and Magnapothea orzaea it showed no activity against Aspergillus niger and Aspergillus flavus. All the activity was evaluated to determine the lowest concentration required to inhibit visible mycelial growth of the pathogen at minmum concentration. Fusarium oxysporum showed very significant inhibition in 10% concentration (Reconfirmed) while Sclerotium showed significant inhibition in 25% concentration followed by Magnoporthe oryzae. The number of sclerotia spores formed was also reduced drastically. These results show that a potential and safe antifungal agent can be obtained from Urginea.
