Research projects on pollution-free pesticides that are of universal importance to the world have recently achieved breakthroughs in Yunnan Province. China's well-known scientific research institutes, universities, venture capital companies, and manufacturing companies have coordinated their efforts to develop and produce a new type of biological pesticide, azadirachtin, on an industrial scale, marking the country’s research in this field has advanced to international advanced Level and show broad prospects. The plant for producing azadirachtin, an eucalyptus plant, is an evergreen tree of the family Polygonaceae. It is an excellent tree species for prevention and control of desertification in dry and hot areas and a plant with the highest utility value for the preparation of pollution-free biological pesticides, prompting many countries around the world to Conduct research, development, and utilization. At present, this research has yielded significant results. There are 16 azadirachtin compounds isolated and completed from the seeds of Neem extracts, of which 4 are new substances that have not yet been discovered abroad and have been studied abroad in the field of chemical basic research. The progress has been synchronized to produce O.3% azadirachtin preparations, 70% neem oil preparations, 10% azadirachtin crude oil, and insect pheromone stem borers, Asian corn borer, beet armyworm, Spodoptera litura, Plutella xylostella and other products, and formulated product standards for chemical products, drug substances, and pharmaceutical preparations, and established a set of detection and control methods that are in line with international standards. It is estimated that once the project is put into operation after one year of construction, it can reach an annual output of 670,000 liters of O.3% azadirachtin, 250 tons of neem oil, 3 million sets of traps, and 15 million lures. Experts here pointed out that natural bio-pesticides have broad market prospects. At present, the total sales of pesticides in China's pesticide market are 6 billion yuan each year, while bio-pesticides only account for 1% of the pesticides; this result is a domestic initiative. The international advanced level will effectively promote the research, development and agricultural production of pollution-free biological pesticides in China.
