Rhizoctonia in Soybeans

Rhizoctonia in soybeans is showing up in the southwest, particularly in fields or areas that are water stressed (wilting). Rhizoctonia has been observed on all soil types and often the worst cases are found on light ground. Characteristic reddish-brown lesions appear at the base of the stem and on roots just below the soil line. They can enlarge into sunken lesions which may girdle the stem resulting in damping-off.
