Kumar, Anil | Raj, Kushal
Black scurf of potato caused by the fungus Rhizoctonia solani Kühn (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.
