1, thoroughly remove the bacteria source. After the fall of the dendrite, it removes the diseased body and concentrates the removed diseased body. In the fall, the buried soil is sprayed 50 to 100 times solibar or 3 to 5 degrees lime sulfur plus 300 times before freezing and before spring. Sodium pentachlorophenol eradicated the source of bacteria to reduce the incidence; timely removal of diseased leaves, diseased fruits, diseased vines in the growing season, and concentrated deep burial.
2, strengthen management. Drain and loosen soil in time after rain; timely tying up vines, picking hearts, keeping air and light in the rack; increasing potassium, calcium and trace elements, and spraying plant growth regulators (such as green wind 95, excessive harvesting, high yield protection, etc.) , improve the function of leaves, enhance tree vigor, and increase disease resistance; 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, chemical control. Ground sprinkling medicine to eliminate bacteria source, on the orchard with serious disease last year, before the disease occurred, lime on the ground; soil with higher PH value can be spread on the ground: Fumei pairs, 1 sulfur powder, 2 limes, The three are mixed evenly and sprinkled on the ground, and the amount of 1 kg to 2 kg per mu can be used; or the under spraying of Fumei 500-600 times or 50% of Carbendazim 500-600 times can control the initial infestation of the soil from overwintering. Source of disease. 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.
