Discovering White Mold
White mold (also named Sclerotinia stem rot) is a common and destructive disease that tends to be sporadic across the northern U.S and Canada. Although it can be a serious problem in many areas, certain areas are more prone to this disease than others. For example, in the central Midwest white mold is especially common in SE Minnesota, NE Iowa, and NW Illinois. White mold is favored by prolonged wet and cool weather when the plants are flowering.
