"Root neoplasm disease" is also called "root cancer disease." If it is not serious, you can use a knife to scrape off the disease, apply 200 times solution of good Lectra +200 times the solution Yi micro, 7 days once, twice in a row. Other non-infected ones can be sprayed with 3000-times finer gram plus 3000-fold solution to prevent spraying, and then the root soil is disinfected with lime sulfur residue. If it is serious, the vines will be excavated immediately and burned in a concentrated manner. Within five years, the plot will not be able to plant fruit trees, and only the field crops will be changed.
Prevention of grape root cancer:
The first is to improve the soil. After determining the pH of the soil (the pH is severe at pH 5.4~6.5), the pH of the soil is adjusted to slightly alkaline to create an environment that is not conducive to the survival of the bacteria.
The second is seedling disinfection. When introducing grape seedlings, strict quarantine should be conducted to avoid the introduction of diseased seedlings. Seedlings should be disinfected before colonization.
The third is to minimize the wound. Avoid mechanical damage to humans and livestock, and pay attention to eliminate underground pests, reduce insect damage, and avoid invasion of pathogens from wounds.
The fourth is before the spring vine germination, spraying a 30% to 5 degree Baume lime sulfur agent, to grape plants, piles, wire, ground and other full-scale spraying, the old grapevines on the incidence of land to be more than spray .
The fifth is to strengthen field management. Control the amount of nitrogen fertilizer, re-apply phosphorus and potassium fertilizers, make up for trace elements, and reasonably load, and gradually strengthen the tree vigor and improve the plant's resistance to stress.
