Identification

The symptoms of powdery mildew are very distinctive making it one of the easier plant diseases to identify. Plants that have powdery mildew have a white, dusty coating on leaves, stems and flowers as if they have been dusted with flour. It starts with powdery, circle white spots which will spread to cover most of the leaves or affected area of the plant. The fungal disease can cause the leaves, buds and growing tips to become twisted, disfigured or break, although this usually happens late into the growing season.
