- The term “snow mold” is a blanket term for any of the several fungal diseases that develop on cereal crops underneath snow.
- The most common snow molds are pink snow mold, Typhula rot (called gray or speckled snow mold), and Sclerotinia snow mold.
- This disease only occurs in areas that receive dense layers of snow prior to soil freezing.
