The rotten fruit caused by rot first appeared on the top of the fruit or the shoulder of the fruit, and the surface was smooth with pale brown spots. Sometimes there was a small amount of white mold, and then gradually formed a concentric scaly plaque, gradually becoming dark brown, and the subcutaneous pulp also browned. In the later period, the whole fruit rots and falls off. Control measures: timely remove the diseased fruit, bring out the field treatment; pay attention to pruning, improve the ventilation and light transmission conditions in the field; in the early stage of the disease, timely spray 25% toxic mycelium 800-1000 times liquid, 75% chlorothalonil 600-800 times liquid Spray once every 7-10 days, even spray 3-4 times. The soft rot caused by soft rot occurs mostly on the green fruit. The skin of the disease remains intact, but the internal flesh decays rapidly, and it has a foul smell and is easy to fall off; it forms a white stiff fruit after drying. Control measures: early pruning, snoring, avoiding rainy weather or pruning before dew; do not prevent pests in time, reduce insect damage; use 150-200ppm agricultural streptomycin solution, 200-400ppm agricultural use before or during the onset of disease Chloramphenicol solution spray control. The anthracnose caused by anthracnose mainly affects the immature fruit. The water-stained transparent small spots in the early stage of the diseased part are brown after the enlargement, slightly concave, with concentric wheel pattern, dense black spots on it, and secreted light red sticky. Finally, the entire diseased fruit rots or falls off. Control measures: timely harvest fruit, timely removal of diseased fruit; before or at the onset of the disease, timely use 70% mancozeb 400-600 times solution, 75% chlorothalonil 600-800 times solution spray control. Fusarium rot caused by Fusarium fruit rot is mainly harmful to mature fruit. The diseased part is light-colored at the beginning, then turns brown, has no obvious edge, and spreads throughout the whole fruit. Prevention and treatment measures: timely removal of diseased fruit, and centralized treatment Prevent the fruit from coming into contact with the ground; spray 50% DT500 times before the fruit is colored. The fruit rot caused by Rhizoctonia solani is only harmful to fruit, and the diseased part is light-colored and water-stained at the beginning, and then spreads into a dark-colored sag, and a brown spider filamentous layer is formed on the surface. The center of the lesion is cracked and the fruit rots. Control measures: timely drainage after rain, prevent water accumulation in the field; timely harvest after fruit ripening; spray 5% Jinggangmycin 1500 times before the onset or early onset.
