Powdery mildew is the most common disease of the gourd, affecting its leaves, petioles and stems. At the beginning of the disease, small round white powdery spots will occur on the surface and back of the leaf, and then gradually expand into irregular white powdery mildew spots, and many small yellow brown dots will appear on the spots in the later stage, and eventually turn brown and die.
