Rhizoctonia Canker & Black Scurf of Potato

Rhizoctonia Canker & Black Scurf of Potato

Rhizoctonia solani attacks the underground stems, stolons, roots, and tubers of the potato plant.  Stems and stolons can be cut off by severe, girdling lesions.  This can lead to a reduction in tuber number and a decrease in tuber quality.
