Abstract
Field and greenhouse testing confirmed that both tuber-borne and soil-borne inocula of Rhizoctonia solani were important in the development of the Rhizoctonia disease of potato. Five criteria were included in the disease rating: percentage of sprout emergence, stem lesions, stolon lesions, pruned stolons and percent usable tubers. Tuber-borne inoculum primarily affected sprout emergence and soil-borne inoculum generally contributed to stolon damage. Lack of visible R. solani sclerotia on tubers was not sufficient to indicate absence of the pathogen. Control of tuber-borne inoculum is an essential part of an integrated program for control of R. solani on potatoes.
