First, to improve soil fertility, choose strong seedlings to colonize and improve the disease resistance of winter jujube seedlings. Second, strict inspection and disinfection of winter jujube seedlings, if the seedlings are found, the diseased plants should be removed in time. Before planting the seedlings, immerse the roots with copper sulfate solution for a few minutes, then rinse with water to prevent phytotoxicity, or disinfect with 600 times of fluoride acid solution. Third, the soil around the diseased plant was sterilized with 1000 times of the drug solution. The mild diseased strain can be used to remove the diseased tumor and disinfected with 1000 times of sputum. Or after disinfection with a hundred drops of drug solution, coated with Bordeaux pulp to protect the wound. Fourth, the diseased plants should be found to be segregated to prevent the spread of germs to the surroundings. The root of the disease should be removed and burned in time, and the wound should be disinfected before being coated with Bordeaux pulp. The soil around the diseased plants can be treated with carbon disulfide. In this way, it can not only disinfect the soil, but also promote the large-scale reproduction of Trichoderma viride. When the pathogen is infested by Trichoderma, it will weaken, thereby inhibiting the growth of the honey fungus. Fifth, in the germination stage of winter jujube seedlings, the Bordeaux mixture is generally sprayed on the seedbed; or the soil can be disinfected by killing the liquid.
