Jujube disease, also known as witches'broom disease, common jujube trees, is a devastating disease of jujube trees, which is spread mainly through insects. The factors influencing the incubation period of jujube madness mainly include: First, grafting time. The disease can be affected by the year of inoculation before the end of June, and symptoms occur only after the inoculation of the following year. The second is the site of inoculation. Inoculated in the roots of the disease on the year, the incidence of inoculation on the branches later, until the next year only the incidence. The third is the amount of inoculation. The number of skin grafts is much faster. The incidence of jujube generally occurs on some shoots, jujube stocks and root pods, and the whole plant has simultaneous morbidity. The symptoms spread from the local to the whole plant. The occurrence of jujube berry disease is related to jujube tree varieties, jujube tree species are different, disease resistance is not the same. Jujube orchards have severe drought, weak management, and weak tree vigor, but they are light on the contrary. However, it rarely occurs in saline areas.

Second, eliminate diseased plants. The diseased jujube strains are the source of disease transmission and must be eradicated as soon as possible, and the roots should be planed so as not to infect other plants.
Third, prevention and control of diseased insects. Each year, 3 or 4 systemic organophosphorus pesticides are sprayed to control the number of infected insects to control the spread of the disease.
Fourth, breeding disease-free seedlings and strengthening quarantine. Persist in the disease-free garden to harvest the ear, shoots and propagation of seedlings, and cultivate disease-free seedlings. Once the onset of symptoms, seedlings should be removed immediately. In addition, we must strengthen quarantine, and do not regulate seedlings and cuttings from the disease area.
