Wheat powdery mildew
Blumeria graminis f.sp. tritici

Wheat powdery mildew (Blumeria graminis f.sp. tritici) is a fungal pathogen of grasses and cereals. It was first detected in Texas in 1984.

Relatively cool and humid conditions are favourable for its growth. Its relatively great genetic variability enables it often to infect previously resistant plant varieties.
