[0002] At present, the method of pest control of crops is mainly to spray pesticides, most of which are mostly chemical pesticides, and my country is a big country in the production and use of pesticides, and pesticides are the main method, resulting in many areas. The amount of pesticide residues in water, food, vegetables and fruits greatly exceeds the national safety standards. For humans, chemical pesticides accumulate in the body and will not cause obvious poisoning in the human body in a short period of time. However, with the increase of chemical pesticide residues The accumulation in the body will gradually cause chronic harm to the human body. Although the chronic harm of chemical pesticides cannot directly endanger human life, it can reduce human immunity, thereby affecting human health and increasing the prevalence of other diseases. Washed into the river, causing the chemical substances and heavy metals in the river to exceed the standard, resulting in the death or even extinction of some aquatic animals and plants
