Problems solved by technology

[0002] With the improvement of people's living standards in our country and the development of science and technology, people have higher requirements for food, clothing, housing and transportation, especially for food safety. People are increasingly favoring green products that are pollution-free and pesticide-free food, vegetables and fruits, but the use of chemically synthesized highly toxic and high-residue pesticides in the prevention and control of pests and diseases for a long time has caused varying degrees of damage to the ecological environment, and has also caused increasingly serious damage to the food that humans and animals depend on for survival. In order to meet people's increasing requirements for food safety, it is necessary to propose a new type of plant insecticide that can effectively kill insects while ensuring the safety of the controlled plants
