Integrated management schedule for control of black scurf disease of potato caused by Rhizoctonia solani

The integrated approach which includes use of disease free seed, 3% boric acid as tuber spray, soil application of gypsum @ 15 q/ha along with fertilizer before planting, light irrigation at 15‐20 days interval, soil pulverization, hot weather cultivation (HWC), harvesting within 20 days after dehaulming and potato based crop rotation-Potato-HWC: GM-Potato proved to be the best for managing the black scurf disease of potato. The above-integrated management reduced the disease incidence from 71.2% (control) to 4.8% and population buildup from 5x10⁷ to 0x10² propagules/g soil.
