Powdery mildew on grapes is scientifically named what?

Explanation:
Powdery mildew on grapes is caused by a fungus named Erysiphe necator. It used to be known as Oidium tuckeri. This pathogen forms the characteristic white, powdery coating on leaves, shoots, and grape berries and tends to thrive in warm conditions with limited free water for germination. It’s different from grape downy mildew, caused by Plasmopara viticola (an oomycete that causes yellow, oily-looking lesions and a white, downy growth on the undersides of leaves), and from Botrytis cinerea, which is the gray mold that rots berries in humid conditions. Phylloxera viticola is an insect pest, not a fungus.
