Is mildew a fungi

Yes. Mildew is a common name for certain fungi that grow on plants or other surfaces. The word is used for different groups, including powdery mildews and downy mildews, which are not all closely related.

How it works

Powdery mildew fungi often form pale, powder-like growth on plant surfaces. Downy mildews resemble fungi and cause similar plant symptoms, but they belong to oomycetes, a distinct group of fungus-like organisms.

Example or application

The name alone does not identify a species or determine the best treatment. Plant symptoms can also resemble damage from other pathogens or environmental stress.

Scope and limits

Mildew on a plant is different from mold growth in a building, and both terms cover diverse organisms. Identification depends on host, appearance, and other evidence.
