The main symptoms occur on the leaves and can spread to petiole and buds when severe. Lesions often occur at the margins of the leaves. In the early stages, faded green maculas, water stains, and many lesions form a contiguous patch. The fan-shaped appearance expands outwards. The edges are dark brown and grayish yellow, which can cause early defoliation. In wet conditions, black-gray particles appear on the fallen leaves. Causes of the disease The disease is a fungal disease. The pathogens survive in the leaves buds and the diseased plant debris. They can spread directly from the weakened or physiologically damaged leaves at the stomata in the leaves, and are harmed by large wind speeds and air humidity. Under small environmental conditions, it is conducive to the occurrence of diseases and severe disease in high-temperature and dry environments. Prevention and control methods Flower buds and buds were not spread, spraying Baume 3 to 5 degrees lime sulfur to the branches. In places where conditions permit, windbreaks (wind-breaking facilities) can be installed in winter to avoid physiological diseases. Increased foliage spraying in the spring to improve the humidity of the small environment. Chlorothalonil and carbendazim fungicides were sprayed 800 times at the beginning of the disease.
