Dry and hot climatic conditions often lead to its occurrence. Therefore, it must be prevented and controlled in time before the advent of the high temperature and drought season.

This problem should be mentioned in the winter of the previous year. Stone sulfur mixture was used in the garden every winter. Spraying stone sulfur mixture in winter will do a lot of effective defense, such as scale insects, aphids, red spiders and some egg-laying pests. The summer garden can be sprayed with water in the morning to lower the temperature, which can also reduce the growing environment of red spiders, but it must be noted that the atomization spray must be ventilated, because it is easy to cause fungal diseases and insect pests without timely ventilation after atomization spraying.

If you have generated a red spider, what you need to do is medication, spray three times in a row every 3-4 days, and spray both sides of the leaf, because the red spider will be hidden on the back of the leaf, and if it is not relieved or killed, you need to change the dressing in time.
