Erysiphaceae is a family of fungi commonly known as powdery mildews. These fungi are characterized by their white, powdery appearance on the surfaces of leaves and stems of various plants. They thrive in warm, dry conditions and can affect a wide range of host plants, including crops and ornamental species. The life cycle of Erysiphaceae involves both asexual and sexual reproduction. Asexual spores, called conidia, are produced on the surface of infected plants and can easily spread to new hosts. Managing powdery mildew often involves cultural practices, such as improving air circulation and using resistant plant varieties.
