How to treat jujube lice?
Jujube lice are tortoise wax scale and scale insects in production. Because the adults form a wax shell, spraying is very difficult to exert its effect, so it can cut off the branches in winter, or spray water on the branches, and knock on the branches to shake off the adults after freezing. The peak of larval occurrence is generally from late June to early July, so there is no wax shell on the insect body, and the larvae have poor resistance to pesticides, which is the best period for control. The use of ordinary pesticides can produce very good results. In this way, a good prevention and control effect can be achieved by persisting for 2-3 years.
