Effect of different aqueous plant extract on the in vitro growth of Fusarium oxysporum f. Sp. ciceri at different time intervals

Various plant extracts have been examined by different investigators for their antifungal activity of exploring environmentally safe alternatives of wilt disease control. After 4 days of inoculation has been found that among concentrations of aqueous plant extracts the highly effective plant was Calotropis procera as it suppressed the growth of the test fungus from 21.00 to 0.00 mm at 10 to 40% concentration where as the second and third effective plant extracts were Azadirachta indica and Withania somnifera while Zingiber officinalis and Allium cepa have shown the similar growth range followed by proved as least effective. After 7 days of inoculation has been found that at all concentration of aqueous plant extract the most effective was Calotropis procera as it suppressed the growth of the test fungus from 38.92 to 2.75 mm at 10% to 40% concentration respectively where as the second and third most effective extracts were of Azadirachta indica and Withania somnifera and the least effective was Nerium oleander.
