Please introduce the control methods of jujube diseases and insect pests in autumn and winter? It is best to have detailed operation methods for the prevention and control of diseases and insect pests of jujube trees in autumn and winter, which can be carried out with reference to the following methods: 1. Clear the garden: jujube rust, green blind stink bug, jujube moth and other diseases and insect pests overwintering in litter or weeds under the tree. Therefore, jujube trees should clean the jujube garden in time after falling leaves, clean up the withered branches and leaves, rotten fruits and weeds, and burn them or bury them deep in the ground. 2. Digging insect pupae and cocoons: according to the habit of peach heart borer and jujube step koji concentrated in the soil around the trunk, combined with the deep turning of the soil, the overwintering pupae and cocoons were picked up before and after thawing, and eliminated centrally, which can effectively reduce the population number in the coming year. 3. Scraping old bark: the temperature under the bark is 1-3 degrees higher than the air temperature. The bark and cracks are the overwintering places for diseases and insect pests such as jujube armyworm and red spider. By scraping the old skin, we can not only eliminate diseases and insect pests, but also stimulate the growth of trees. Scraping is carried out from defoliation to germination. When scraping, spread plastic sheeting under the tree so that the bark and pupae can be collected, then burned or buried. 4. Whitening: the trunk is painted white, which can not only prevent cold but also prevent diseases and insects. The formula of whitening agent is as follows: 12 parts of quicklime (boiled with cold water), 2 parts of sulfur or 3 parts of stone-sulfur mixture, 2 parts of salt (boiled with hot hydration), 36 parts of water and proper amount of glue. Lime and sulfur can prevent frost and sunburn, but also prevent diseases and pests. Salt helps lime infiltrate into the bark to maintain moisture and prevent lime from cracking and peeling off. Adding glue can enhance the adhesion of the whitening agent. The white part should be high, and all branches that scrape off the old skin should be painted white to prevent dry tips. 5. Blocking the tree hole: the old tree hole is easy to breed diseases and insects, and it is also an overwintering place for jujube armyworm and other pests. In winter, 10 parts of clay soil and 3 parts of chopped wheat straw can be added with a little insecticide, and the tree hole can be blocked with water and mud to kill the pupae of overwintering insects. 6. Pruning insect branches and cocoons: combined with winter pruning, the insect branches damaged by the tortoise wax scale can be cut off. For the seriously damaged branches, the overwintering insects can be removed by wire brushing, and the overwintering cocoons of the yellow thorn moth should be cut off. 7. Spraying chemicals: because the tortoise wax scale has a wax shell on its surface, it is difficult for chemical pesticides to kill it, so it can be eliminated by spraying diesel emulsion. Before the jujube tree germinates, the whole tree is sprayed with Baume 5-degree stone sulfur mixture uniformly and meticulously, which can control red spider, pear orchard scale and other pests.
