Figure 2. Symptoms of alfalfa plants affected by Sclerotinia crown and stem rot. A: Diseased alfalfa stems have a bleached, dry appearance. Infected plants become wilted and eventually collapse in the field due to stem and crown rot, which softens and weakens the stem. B: White arrows represent the wilted plants spotted in the field.
