1. Thoroughly remove the bacteria source before the fall of the dendrite in the autumn to remove the diseased body, and concentrate the removed diseased body; in autumn, the buried soil is sprayed 50 to 100 times the Sooliban or 3 to 5 degrees before cold protection and unearthed in the spring. Sulfur compound plus 300 times of sodium pentachlorophenol to eradicate the source of bacteria, reduce the incidence; timely removal of diseased leaves in the growing season, disease, disease vines, concentrated deep. 2. Strengthen the management of timely drainage and loose soil after the rain; timely tying up vines, picking up the heart, maintaining the ventilation and light transmission in the rack; increasing the application of potassium, calcium and trace elements, spraying plant growth regulators (such as green wind 95, must receive more, High-yield security, etc.) Enhance blade function, increase tree vigor, improve disease resistance, and control yield and reasonable burden. In accordance with the growth of plants to determine the yield, the average age of orchards per mu should be controlled at 2500 kg to 3500 kg. 3, pesticides to control the ground to eliminate bacteria source. For the orchard with severe disease in the previous year, before the occurrence of the disease, lime is poured on the ground; the soil with higher PH value can be used for ground spreading: one for Fumei, one for sulfur powder and two for lime, and the three are mixed and sprinkled in Ground, the amount of 1 kilogram to 2 kilograms per acre; or under the frame spray Fumei double 500 ~ 600 times liquid or 50% carbendazim 500 ~ 600 times liquid can control the source of the initial infection from the soil overwintering. Spray protection. During the growing season spray 1:0.5 to 0.7:200 Bordeaux mixture. Spray once every 10 to 15 days to protect the leaves, branches, ears, etc. to reduce the chance of infection; against the disease, the right medicine. Once white rot, anthracnose and other diseases occur, apply the medicine symptomatically, but pay attention to the alternation of use of the agents, and do not use a single drug. After the fruit is stained to prevent pesticides from contaminating the ear, use 500 times 9281 or 12% green copper 600 to 800 Times.
