Dutch powdery mildew is a fungal disease. Pathogens damage leaves, vine vines and pods. At the beginning of the disease, the leaves appeared pale yellow dots, followed by a white powder at the site of the disease, and after the enlargement, they showed an irregular form of pink spots, which quickly spread to the entire leaf and covered a layer of flour. It was called powdery mildew. At the later stage of disease, the diseased department had scattered small black particles. The victim's leaves soon yellowed and the leaves fell off. When the stems and stems were damaged, white patches appeared. When the stems were severe, the stems turned brown and the pods shrank.
