Problems solved by technology

[0002] In agricultural production, in order to ensure the healthy growth of plants, people mainly eliminate pests by spraying chemical pesticides. However, many organic compounds containing chlorine and phosphorus in pesticides can effectively kill pests, but the residues on food, vegetables, and fruits Pesticides have caused great harm to human health
[0003] For a long time, due to the extensive use of chemical pesticides, not only the pollution of the ecological environment has been caused, but also some diseases and insects have developed a certain degree of drug resistance, resulting in a further increase in the amount of chemical pesticides; at the same time, chemical pesticides have caused damage to agricultural by-products, groundwater, etc. Certain pollution has caused certain harm to the environment
