White Mold , Stem Rot - Sclerotinia sclerotiorum

White Mold Life Cycle

White mold, caused by the fungus Sclerotinia sclerotiorum, is an important yield limiting disease of soybeans in the north central United States. The fungus is endemic to the north central U.S., and infects almost all dicotyledonous plant species. Because of its wide host range, it is an important pathogen of a wide range of agricultural crops including dry beans, sunflowers, canola, potatoes, and all forage legumes.

This web site includes a graphic of white mold's life cycle, and how its life cycle corresponds to plant development. The life cycle graphic is also an image map with several clickable regions, so you may obtain details about a specific area of interest.

White Mold Management Practices

Management of soybean white mold requires adoption of an integrated package of practices for disease control. Management practices interact with the white mold pathogen at every stage of the fungal life cycle.
