Powdery mildew database
Washington State University plant pathologist Dean Glawe has compiled a database on the world’s Erysiphales fungi, which cause some of the world’s most damaging plant diseases, including powdery mildew. There are nearly 700 species of Erysiphales, which vary in their life cycles, hosts, and capacity to cause damage. Growers apply more fungicides to control powdery mildews than any other plant pathogen, Glawe says.
The database enables users to identify powdery mildews, find information about their host plants, and access online scientific resources.
