The symptom of pink rot are typically observed in tubers, but severe infections may develop foliar symptom such as wilting, yellowing, and aerial tubers. Infected tubers exude a clear, watery liquid. The tissue remains intact, but has a rubbery texture. When infected tubers are cut open, a pink colour develops within 30 minutes, and later turns black. The tuber decay may proceed into the tuber from the stolon end, and a line may be visible between healthy and infected tissue.
