Powdery mildew is a cryptogamic disease caused by different fungi of the Erysiphaceae family. It can be recognized by the white, powdery spots appearing on the leaves, which can deform and fall.
By weakening plants, it reduces harvests in the vegetable garden and harms the ornamental appearance of plants. Milk is an excellent ally in the fight against powdery mildews. It is also possible to use it as a preventative measure, once a month.
