A: This situation belongs to early defoliation disease, which is a fungal infection disease. The occurrence of this disease is related to rainfall. Therefore, farmers should do a good job in preventing the disease before the rain, and spray protective fungicide for the whole garden; after the rain To do a good job in the treatment, the whole park sprays systemic fungicides, such as methyl thiophanate, tebuconazole, diniconol and so on. However, in this process, farmers need to pay attention to the fact that long-term use of a single agent to prevent early defoliation will make the bacteria resistant, so the use of fungicides should pay attention to rotation. Generally, the orchard leaves with large amount of fruit and poor soil organic matter are not well developed. The waxy layer is thin, and the waxy layer is thin, which makes the pathogen easy to invade and causes the tree to be infected. Therefore, the fruit grower can increase the thickness of the wax layer of the leaf by using potassium fulvic acid and potassium dihydrogen phosphate.
