一、我国农药创新取得的巨大成就半个世纪以来,我国农药各方面的创新取得了相当大的成绩,走出了一条“半仿半创与仿中有创”的技术进步捷径。1、农药品种方面(1)仿中有创。我国农药品种多为仿制,极少购买专利。因此,仿制中在合成路线、工艺条件、设备选型等方面不可能跟国外投产情况完全一致,其中部分品种可能超过国外水平。如敌百虫、乐果、林丹等。(2)半仿半创。如杀虫双、杀虫单(仿制杀螟丹而研制),混灭 I. Great Achievements Made in China’s Pesticide Innovation Since the past half century, all aspects of pesticide innovation in China have achieved considerable success and have come out of a shortcut to technological progress that is semi-fake and semi-fake. 1, pesticide varieties (1) imitation invasive. Most varieties of pesticides for imitation, rarely buy a patent. Therefore, the imitation in the synthesis route, process conditions, equipment selection and other aspects of production can not be exactly the same with foreign countries, some of which may exceed the level of foreign countries. Such as trichlorfon, dimethoate, lindane and so on. (2) semi-imitation semi-invasive. Such as insecticidal double, insecticidal single (imitation Cartap and development), mixed off
