Problems solved by technology

[0002] There are many pests in the soil, which damage the roots of crops and seriously affect the growth of crops. Commonly used pesticides include organochlorine pesticides, etc., which often have a great impact on the soil. With the development of pollution-free agricultural products in our country Vigorously promote the implementation, high-efficiency, low-toxicity, and low-residue pesticides are gradually favored by consumers, and the widely used pesticides are still chemical preparations after all. Although they have good insecticidal effects, this low-residue chemical It will also cause pollution to the environment, have toxic and side effects on humans and animals, and is not conducive to long-term development
