[Cause] Botrytis blight, also called gray mold, a fungus disease that spreads in moist air and cool temperatures. It can be widespread in spring, and often appears on mail-order roses that have been kept in a dark damp box during shipping. [Solution] There are no chemical cures for blight once it occurs. If symptoms appear, cut off and destroy all infected plant parts. Spray with a fungicide to keep the disease from spreading. [Problem/Symptom] 
Rosebuds fail to open and are covered with a grayish brown, fuzzy mold. Open flowers are flecked with yellow or brown and lower petals are wilted and brown. The stems below infected flowers become discolored.
