Liu Changling's Personal Achievements

The new pesticide variety flumorph created by him is the first pesticide variety with independent intellectual property rights in the history of China, the first agricultural fluorine-containing fungicide patented in China, and the first new pesticide variety patented in the United States and Europe. This variety has the characteristics of high efficiency, low toxicity and safety to crops, human beings and the environment, and is well received by farmers. Since the variety was put into production, it has produced billions of social benefits and created more than 60 million yuan in profits and taxes. He was awarded the China Invention Patent Award, the Special Gold Award of Liaoning Invention Patent Award, the first prize of China Petroleum and Chemical Industry Technological Invention Award (ranked first) and the second prize of National Technological Invention Award (ranked first).

Through years of exploration, research and summary, Liu Changling initially found a new method of pesticide innovation research suitable for China's national conditions, that is, "intermediate derivatization combined with bioequivalence theory". Lead compounds can be found quickly, and finally new products with independent intellectual property rights can be obtained. This method has achieved initial results and can be popularized and applied. Under his guidance, researchers in the new drug room discovered more than 30 highly active compounds from 1997 to 2006. The results of field test and toxicity test show that at least four new products with independent intellectual property rights have been funded by the "Eleventh Five-Year Plan" of the Ministry of Science and Technology.

Liu Changling and his collaborator * * * applied for 28 invention patents in China, 22 of which have been made public, and 12 was authorized; He applied for 23 foreign patents, published 12, and granted 3 patents.
