Black scurf is one of the oldest and common diseases of potato stems and
stolons below the soil surface caused by Rhizoctonia solani. The present study was
carried out to investigate the antifungal potential of Melia azedarach against this soilborne
fungal pathogen. Different concentrations (1, 2, …, 5%) of aqueous, methanol, nhexane

and were evaluated for their in vitro antifungal activity. Data were analyzed by Tukey

Abstract
Black scurf is one of the oldest and common diseases of potato stems and stolons below the soil surface caused by Rhizoctonia
solani. The present study was carried out to investigate the antifungal potential of Azadirachta indica L. against this soil-borne
fungal pathogen. Different concentrations (1, 2, 3, 4, 5%) of aqueous, methanol, n-hexane and chloroform extracts of leaves,
stems and fruits of A. indica were prepared and were evaluated for their in vitro antifungal activity. Data showed that all the
