Black rot is caused by the fungus Ceratocystis fimbriata. The disease can cause significant losses in storage, in the transplant bed, and in the field. The pathogen not only reduces yield and quality but also gives sweet potatoes a bitter taste. Small, circular, slightly sunken, dark brown spots are the initial symptoms of black rot (Figure 1).
