Rhizoctonia root rot is an important bean disease in southern Idaho crops that has caused from 30% to 100% yield loss, depending on the degree of severity. The culprit is a soilborne fungus, Rhizoctonia. This bulletin discusses the symptoms and signs of an outbreak, the pathogen’s disease cycle and management practices (including the results of a chemical control study conducted in Parma).
