Visiting Senior Landscape Architect Yu Hongan, School of Life Sciences, Northwest University
In recent years, the ulcer disease of kiwifruit has become more and more serious, which has caused much attention. On March 12th, the reporter interviewed Yu Hongan, a senior horticulturist of Northwestern University’s Academy of Life Sciences. He said that kiwifruit canker disease should be mainly prevention and integrated prevention and treatment. .
Reducing Pathogens The kiwifruit canker is mainly found in susceptible plants and diseased bodies in the field, including cut-off diseased vines, scraped diseased cortex and other litters, and carefully cleaned up the diseased branches in autumn and winter. Diseased leaves, diseased parts of cortical tissues that are produced when diseased branches and scratched lesions occur in spring, and destroy them centrally are the main ways to reduce the pathogens of kiwifruit ulcers.
Reducing Pathogens to Invade Pathway When ulcers are used in agricultural operations such as wind and rain, insects, or pruning, they invade plants from stomata, water holes, lenticels, and wounds (insect damage, frostbite, knife wounds). Usually kiwifruit tree body is always due to natural, man-made, pests and other causes of some wounds, production found in leaf aphids, cockroaches, plagioclase, etc. on the wound caused by the wound is often the first outflow of ulcer disease fluid The site, through various ways to reduce these wounds conducive to the invasion of ulcer disease can effectively reduce the incidence.
The germs that kill the tree destroy the germs on the surface of the tree and the bacteria that invade the interior of the tree become a key link in the prevention of ulcer disease. Developed by Northwest University and produced by Beijing Zhongzhi Kehua Agricultural Technology Co., Ltd., Beibo fluorosiliconazole has dual functions of preventing and treating fungal and bacterial diseases, has strong permeability, and has a significant preventive effect.
Comprehensive agricultural measures maintain a strong tree vigor through the use of good stocks, balanced nutrients, reasonable loads, and standardized pruning. Even if the ulcers invade the tree and do not develop disease, it will play an important role in reducing the incidence of ulcers.
