Publication 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 Melia azedarach against this soilborne
fungal pathogen. Different concentrations (1, 2, …, 5%) of aqueous, methanol, nhexane
and chloroform extracts of leaves, stems and fruits of M. azedarach were prepared
and were evaluated for their in vitro antifungal activity. Data were analyzed by Tukey
HSD test at 5% level of significance. All the extracts showed variable antifungal activity.
In general, leaf extracts exhibited the highest inhibitory effect against growth of the
fungal pathogen followed by stem-bark and fruit extracts, respectively. Among the various
extracts, leaf chloroform extract, stem-bark methanolic extract and fruit aqueous extract
showed the best antifungal activity resulting in 20–89%, 4–85% and 28–70% reduction in
fungal biomass over corresponding control treatments, respectively.
