If the seeds are infested with insects, measures should be taken as soon as possible, and the insects should be controlled according to the principle of "safe, economic and effective" to minimize the loss. The commonly used methods of controlling insects in production include physical, mechanical and chemical methods. Mechanical pest control: It uses human power or power machinery such as windmills, sieves, etc. to remove pests. Through mechanical movement, not only the pests can be separated from the seeds, but also the pests can be killed by mechanical impact.

Physical treatment of insects: refers to the use of natural or artificial high temperature, low temperature and atomic energy rays to destroy the reproductive and physiological functions of the insects in the warehouse and the structure of the insect body, so that the insects lose their growth and reproductive ability or denature the protein components in their bodies. lethal. Such as the use of sunlight or freezing, on the one hand, it can reduce the moisture of the seeds, worsen the environmental conditions of the pests, and make them unable to move, on the other hand, it can directly kill the pests.
Chemical pest control: the use of toxic chemicals to destroy the normal physiological functions of pests, creating conditions that are not conducive to the growth and reproduction of pests, so that the pests stop their activities or are directly exposed to drugs and are poisoned to death. Currently commonly used drugs are aluminum phosphide, chloropicrin, dichlorvos and so on. Although the application of chemical agents to kill insects has the advantages of high efficiency, speed and economy, improper use will often affect the germination rate of seeds and affect the health and safety of workers. Therefore, when using drugs to treat insects, you must pay special attention to the operating procedures and techniques, and you must not be careless. The more skilled staff will participate in the field operation and guidance to prevent accidents.
