1. Red spiders have appeared on the flowers. How can I kill them?

In the process of cultivating flowers, red spiders are common destroyers. The flowers that are harmed by them include roses, Milan, jasmine, kumquat, crabapple, osmanthus, and bergamot. This insect is very small, less than 1 mm, round or oval, orange or reddish brown. Because of its small size, it is not easy to find. Once it is found to be harmful, the flowers are often seriously damaged. This insect uses its mouthparts to pierce the leaves and suck juice, which destroys the chlorophyll, and the leaves show gray-yellow spots or patches. The leaves are orange, fall off, and even fall off. Red spiders have a strong reproductive capacity and can reproduce a generation in as fast as about 5 days. This insect likes a high temperature and dry environment. Therefore, under high temperature and dry climate conditions, it reproduces rapidly and causes serious damage. The insects often gather on the back of the leaves of flowers to spin silk and weave webs to cause damage. In addition to crawling by themselves, wind, rain, and operation are important ways for the spread of red spiders. To prevent and control red spiders, you should pay attention to observation. When you find abnormal color of leaves, you should carefully check the back of the leaves. If individual leaves are damaged, you can remove the insect leaves. When more leaves are damaged, you should spray them as soon as possible. Commonly used pesticides include cypermethrin, dicofol, dimethoate, cypermethrin, and cypermethrin. For home flower cultivation, you can prepare a flower sprayer. In 400 ml of water, cypermethrin, cypermethrin, or cypermethrin can be dripped into 4 drops (equivalent to 2000 times the liquid medicine), and cypermethrin or dimethoate can be dripped into 8 drops (equivalent to 1000 times the liquid medicine). After adding the medicine, shake it well and spray it immediately. The spraying requires uniformity and thoughtfulness, especially pay attention to spraying the back of the leaves. When spraying, it is best to move the potted flowers outdoors. If you spray indoors, do not approach food or utensils. After each use, pour out the excess liquid medicine and wash the sprayer with clean water.
