AI Technical Summary

Problems solved by technology

The biggest defect of chemical pesticides to prevent and control diseases and insect pests is the amount of pesticide residues. Although many existing pesticide varieties have the characteristics of high efficiency and low toxicity, which are relatively safe for humans and animals, there are still a large part of pesticides with long residual time and poor chemical properties. Stable, while killing pests and diseases, there are a large number of residues in crops, and the amount of residues increases with the increase of pesticide application, which greatly exceeds the safety limit. Chemical pollution is becoming more and more serious, and the environment and food that people depend on are increasingly polluted by chemical pesticides. Food safety has become a topic of common concern to human beings. How to fundamentally eliminate chemical pesticide pollution from the source , is the dream wish of scientific and technological workers. After years of exploration and research and a large number of field experiments, a pure Chinese herbal medicine has been found.
