Red spider is one of the jujube diseases and pests, and it generally begins to harm jujube trees in the middle and late June. It occurs in multiple generations in one year. After the jujube leaves were damaged, the leaves turned yellow and litter, further causing fruit drop and affecting the yield. Specific prevention methods: scrape the bark in the early stage of jujube tree growth, turning the tree disk, but also use 3-5 degrees of lime sulfur to kill overwintering. After 5 and 6 months, when the insect population density reaches 0.5/leaf on average, acaricides should be used for prevention and treatment in time. Can be used 40% dicofol 1000 times liquid, 20% dying net 800 times liquid, 20% lycopene 2000 times liquid, 50% 1605 emulsion 1500 times liquid or killing No. 1 3000-4000 times liquid, can achieve control purposes.
