Black scurf of potato caused by the fungus Rhizoctonia solani KÃ¼hn (teleomorph Thanatephorus cucumeris (A. B. Frank) Donk), commonly affects the tubers, sprouts, stems and stolons at different times during the growing season. Bioefficacy of different fungicides [penflufen 240 FS (0.042%), penflufen 240 FS (0.062%), penflufen 240 FS (0.083%), Monceren 250 EC(0.25%), carbendazim 50 WP (0.3%) and Emisan 6 FS (0.25%)] was evaluated against black scurf of potato by dip treatment on Kufri Bahar cultivar. Penflufen (0.062, 0.083%) dip treatment of scurf infected tubers for 10 minutes provided more than 97% disease control and both these concentrations were statistically at par.
