Three ways to deal with insect seeds

Seed pests should take measures as soon as possible, according to "safe, economic, effective," the principle of pest control, so that the loss is reduced to a minimum. The pest control methods commonly used in production include physical methods, mechanical methods, and chemical methods.

Physical rule of law worm: refers to the use of natural or artificial high temperature, low temperature and atomic energy rays, etc., to destroy the reproductive and physiological functions and worm body structure of the worm in the worm, causing the larvae to lose their growth, reproductive ability or to denature protein components in the body. And lethal. For example, the use of sunlight exposure or freezing can, on the one hand, reduce the moisture content of seeds, aggravate the environmental conditions of pests, make them incapable of moving, and on the other hand directly kill insect pests.

Mechanical rule of law and pests: It is the use of manpower or power machinery such as windmills, sieves, etc. In addition, mechanical movement can not only separate pests from seeds, but also cause the insects to die through mechanical impact.

Chemical agents: The use of toxic chemical agents to destroy the normal physiological functions of pests, resulting in conditions that are detrimental to the growth and reproduction of pests, so that pests can be killed or stopped by direct contact with drugs. Currently used drugs are aluminum phosphide, chloropicrin, dichlorvos and so on. The use of chemical pesticides has the advantages of high efficiency, rapidity, economy, etc. However, improper use may affect the germination rate of seeds and affect the health and safety of workers. Therefore, when using drugs to treat pests, special attention must be paid to operating procedures and techniques. Care must not be taken. It is better to involve more skilled staff in field operations and guidance to prevent accidents.

In fact, this is a botanical product that can replace cigarettes.
