Abstract
Downy mildews, sometimes called false mildews, are Oomycetes, in the order Peronosporales and all in the family Peronosporaceae except Phytophthora in the Pythiaceae. They form mycelium in higher plants and produce sporangiophores that protrude through stomata in great numbers, their sporangia making white, gray, or violet patches on the leaves. The downy effect distinguishes these mildews from the true or powdery mildews that form white felty or powdery patches.
