One of the most important diseases affecting dry beans in western Nebraska and Colorado is white mold caused by the fungus Sclerotinia sclerotiorum. White mold is first observed as wet, soft spots or lesions on infected leaves, branches, stems and pods. These lesions enlarge into a watery, rotten mass of tissue that is covered by a white moldy growth. Infection of stems and branches will cause affected plant parts to wilt and later die, taking on a bleached and dried appearance.
Please see the fact sheet White Mold of Dry Beans additional information on the disease and control options.
