Some suggestions for relieving pesticide residues

With the growing severity of pesticide residues and the importance attached to them, the development of green pollution-free pesticides has been put on the agenda. Looking at the development situation of pesticides in the world, we are looking for a new generation of pesticides with high efficacy, low dosage, and safety that are harmless to the environment. This is a goal for the pharmaceutical industry in the world today. Strengthening the safety evaluation of new YIYI drugs, and further using pesticide residue detectors to strictly monitor food safety, will become a major issue for pesticide residue research.

As far as the development trend of pesticides in China is concerned, chemical pesticides will be replaced with larger ones. However, pesticides still use organic phosphorus and ammonia as the formic acid-based pesticides; fungicides, there is still a primary sulfur protective agent. Occupying an important position, bionic pesticides such as pyrethroids (plant bionics) will have greater development, chitin preparations and other biological agents will also make new progress, various types of weeding The agent will have a certain amount of increase; the physical method has insecticidal lamps, which greatly eases the use of some pesticides.

1. Actively carry out studies on the safety evaluation of various new pesticides. Select new pesticides with promising development, conduct research on the effects of pesticides on the agricultural ecological environment and the ecotoxicology of pesticides, in order to make a comprehensive safety assessment and test the residual trends of agricultural eco-environmental napkins for pesticide production in China. Decision-making provides a scientific basis.

2. China has decided to stop the production and use of BHC and DDT. However, due to the long residual period of BHC and DDT, after stopping the river, it is still necessary to discuss the long-term residual environmental impact and fate problems. Sexual monitoring will continue to be the subject of pesticide residue research. Therefore, on the basis of the trials of the first three years (1980-98), we will continue to collaborate with Zhejiang Medical University to study the effects of 666 pesticides on the ecology and humans of the Inagawa River in Zhejiang Province, and at the same time develop a set of pesticide ecology. The toxicological research approach provides a complete research method for the comprehensive evaluation of a new pesticide in the future.
