In July, walnut branch blight was prevalent, and Lu Zhoumin, a researcher at the Forestry College of Northwest Agriculture and Forestry University, reminded farmers that the walnut branch blight caused by fungal infection is mainly harmful to trunks and should be promptly controlled. The reason for this is that the garden is not completely clear. The pathogens overwinter on dead branches and the spring of the year is spread by wind, insects, and rain. Inadequate management is also due to lack of water and fertilizer, which weakens the tree body, reduces disease resistance, and has a high incidence rate. Soil hardening, poor root system development, and low absorption capacity. In the management process, due to careless operation, mechanical wounds are also beneficial. Invasion of pathogens; late frost damage can easily cause saplings and shoots to infect the disease. The park is shaded, with poor ventilation and light transmission, and the branches are tender and easy to cause disease. Control measures to strengthen management, fertilizer application. In combination with deep-turning each adult tree, 200 kg of decomposed organic fertilizer was applied, followed by nitrogen, phosphorus and potassium compound fertilizers in June. Irrigate water in time to promote robust growth of trees and improve disease resistance. Cut off the dead branches and find that the sick branches are cut off in time and brought out of the park and burned. At the same time do a good job in summer cut, remove sticky branches, pests and branches, leggy branches, improve ventilation and light conditions, reduce the incidence. Chemical control: 70% thiophanate-methyl WP wettable powder 800 to 1000 times or 400 to 500 times MnZn wettable powder spray control from June to August, spraying once every 10 days, and spraying three or four times Can receive a clear control effect. At the same time, it is necessary to prevent and control pests such as cloud beetle and walnut small giardia in time to prevent bacteria from invading.
