Lesion size varies, but lesions are usually small and brown, surrounded by a narrow yellow zone. Water-soaked tissue may not be noticeable, but if present appear as small circular spots on the lower leaf surface. The centers of old lesions fall out, leaving tattered strips or holes on affected leaves. If the disease becomes systemic in the plant, lesions can occur along the stem. Pods from infected plants may be bent or twisted with visual ring spots. Water-soaked brown lesions can form on pods. Older plants and plant parts are more resistant to infection. The disease can reduce both seed yield and quality, and can be very damaging when weather conditions are favorable to the pathogen.
