WHO CAUSES IT?
Podosphaera aphanis, commonly known as powdery mildew, is a pathogenic fungus that affects various plants, including strawberry (Fragaria x ananassa). This fungus occurs in the form of spores that can be easily dispersed by wind and irrigation water. Podosphaera aphanis is especially active in conditions of high humidity and moderate temperatures, where it finds an environment conducive to its development and propagation.
SYMPTOMS
The disease caused by powdery mildew in strawberries is characterized by the presence of a white or grayish powder on the leaves, stems and fruits of the plant. This powder consists of the fungal structures of the fungus and is most noticeable on the underside of the leaves. In addition to dust, symptoms include curling and deformation of leaves, as well as reduction in fruit size and quality. In severe cases, powdery mildew can cause defoliation and weakening of the plant.
