Prevention and treatment of jujube diseases and pests need to start from dormancy
Jujube tree diseases and insect pests are the biggest problems and problems in the management of jujube trees. Bad treatment can cause great losses. At the same time, the chemical control during the growth period not only increases the cost of prevention and control, but also brings great hidden dangers to the quality of jujube fruit, which easily leads to excessive pesticide residues. According to the overwintering characteristics of jujube pests and diseases, combined with winter management, targeted prevention and treatment can have a multiplier effect. Clear Garden. Jujube rust, green-lipped mycosis, juvenile spiny moths and other pests are overwintering in the litters or weeds under the trees. Therefore, jujube trees should be cleaned in time after the fallen leaves to clean up the dead leaves, rotten fruit and weeds in the garden. , and concentrated burned or buried in the ground, you can clear part of the overwintering pests and diseases. Dig worms and insects. Based on the wintering habits of peach borer and zaobu ququ focused on the soil around the trunk, in combination with deep soil turning, the overwintering insects and insects were collected before the soil was frozen and thawed, and the insects were destroyed in a concentrated manner, which effectively reduced the number of insect populations in the coming year. Scrap old skin. The temperature under the bark is higher than the temperature, and the bark and tree gap are the overwintering sites for pests and diseases such as the Chinese dateworm and red spider. By scraping the old skin, you can not only eliminate pests but also stimulate tree growth. The scrapings are carried out after defoliation and before germination. When scraping the skin, lay a plastic sheet under the tree to collect the bark and insects, and then burn or deep. White paint. Whitening the trunk can not only prevent the cold but also prevent and treat pests. The formulation of whitening agent is 12 parts of quicklime (open with cold water), 2 parts of sulfur or 3 parts of lime sulfur stock solution, 2 parts of salt (opened with hot water), 36 parts of water, and proper amount of glue. Lime and sulfur can prevent freezing, prevent sunburn, and prevent disease and kill insects. Salt helps lime penetrate the bark to keep moisture and prevent lime cracking and peeling. Adding glue can enhance the adhesion of the whitening agent. The white part of the painting should be high. All the branches that scrape off the old skin should be painted white to prevent dry tips. Cutworm branches, insects. In combination with winter pruning, cut off the larvae damaged by the turtle's wax beetle. For severely damaging branchlets, the overwintering insects on them can be removed with a wire brush, and the overwintering bugs of the yellow thorn moth must be carefully removed. Spray pesticides. Because there is a layer of wax shell on the surface of turtle wax, it is very difficult for general chemical pesticides to kill it. It can be sprayed with diesel emulsion to eliminate it. Before the jujube sprouts, the entire tree should be sprayed evenly and thoroughly with Baume 5 degree lime sulfur, which can control the red spider, pear orchard and other pests.
