SUMMARY A corky rot affecting seed tubers of potato cultivar Jersey Royal is described. The disease, caused by Fusarium oxysporum , occurred on many farms in Jersey in 1968 and 1969. No symptoms were seen in the growing crop or at lifting in June, but dark brown sunken corky lesions, 15 mm diameter, were seen in the autumn. The infection rarely penetrated more than 2 mm and most infected tubers produced a satisfactory crop when planted. The disease did not progress during the winter, and infection seemed to be associated with high temperatures prevailing soon after lifting.
