Researchers at the Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences and Zhejiang Research Institute of Chemical Industry have recently developed two new types of herbicides for high-efficiency rapeseed field--propyl arysteryl ether and isopropyl ester herbicidal ether and their 10% EC formulations. The new pesticide registration certificate and production approval certificate issued by the Ministry of Agriculture and the National Development and Reform Commission have become one of the few pesticides in China with independent intellectual property rights. On February 28th, experts from all over the country fully affirmed after the field demonstration of the Shanghai Academy of Agricultural Sciences in Dachang. They believe that the smooth implementation of the project will greatly enhance China's entry into the WTO and create new varieties of green pesticides with independent intellectual property rights and promote Its industrialization confidence. It is understood that after more than six years of hard work, researchers from the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences and the Zhejiang Chemical Research Institute have discovered a class of pesticide lead compounds with new structure and high herbicidal activity - 2-pyrimidinyloxy-N -Arylbenzylamines, and based on this, the first two herbicides were developed. According to the project leader and researcher Lu Long, deputy director of the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences, the two new herbicides can effectively control the main single and dicotyledonous weeds in rapeseed fields, and have the advantages compared with existing herbicides in rape fields. The characteristics of high efficiency, low toxicity, safety to rear crops, good environmental compatibility, broad spectrum of grass killing, and low cost have filled the gap in the current treatment of rape fields in China as well as single and dicotyledon weed herbicides. As 2-pyrimidinyloxy-N-arylbenzylamines are pesticide lead compounds with China's independent intellectual property rights, researchers have applied for five Chinese invention patents, and also completed 17 designations in the European Union and the United States. Country's patent application. In particular, it is worth mentioning that the pesticide lead compound discovered by Chinese scientists is a brand-new structure. At present, there are more than 20 new compounds that are conducting different efficacy verification tests, and it is hopeful to develop a series of proprietary intellectual property rights in China. New pesticide varieties. This scientific research achievement has been recognized by the international counterparts. They have signed a patent license and a joint development agreement with Bayer AG of Germany. They will jointly develop this novel 2-pyrimidinyloxy-N-aryl group with high herbicidal activity. Benzylamine derivatives. It is still the first case in the field of the creation of new pesticides in China that the world’s famous multinational corporations have made use of the inventions of China’s inventions for secondary development.
