Last Updated: 2024/11/09, How to prevent cherry root cancer? The tumor at the cherry root neck is caused by a bacterium belonging to the genus Agrobacterium and is called cherry root cancer. The most obvious symptom of this disease is the formation of spherical or hemispherical nodules at the root neck. The nodules are white and soft in the early stage, then gradually enlarge and lignify. The tumor surface is rough, brown or dark brown. Cherry root cancer often causes poor growth of the plant above ground, yellow leaf color, serious plant death. The pathogenic bacteria of cherry root cancer survive and overwinter in the surface layer and soil of the diseased plant cancer tumor.

How to prevent and cure root cancer of cherry blossoms?

The tumor at the root neck of cherry blossoms is caused by a bacterium of the genus Agrobacterium, called cherry blossom root cancer. The most obvious symptom of the disease is the formation of globular or hemispherical nodules at the root neck. At the initial stage, the tumor was white and soft, then gradually enlarged and Lignified. The surface of the tumor is rough, brown or dark brown. The root cancer disease of cherry blossoms often leads to poor growth of the aboveground parts of the plant, yellowing of the leaves and death of the plant in severe cases.

The pathogenic bacteria of cherry blossom root cancer survive the winter in the surface layer and soil of the diseased plant. When the surface part of the tumor is decomposed, the bacteria enter the soil and can survive in the soil for a few months to a year or so. Pathogenic bacteria are mainly transmitted by irrigation water or Rain Water, and can also be transmitted by grafting tools or underground pests. Often invade plant tissue from graft interface and mechanical wound. The disease is serious when the soil is heavy, the humidity is too high and the barnyard manure is overused.

The prevention and control measures of cherry blossom root cancer disease are as follows: first, strengthen seedling quarantine and select "disease-free" plants. All kinds of mechanical wounds of the plant were soaked in 1% copper sulfate solution for 5 minutes, washed with clean water and planted. Second, when mild diseases are found, the cancer should be removed in time, and the wound should be protected by plant ash or sulfur powder. The seriously diseased plants were uprooted and burned. Disinfection of diseased soil can be mixed with chloropicrin after being evenly sprinkled with 60: 120 grams per square meter.
