苯达松(又名灭草松,噻草平)是一种高效、低毒、低残留的新型除草剂。西德巴登苯胺碱公司于1968年研制成功。美、日等国先后引进该技术。1975年,四川省化工研究所进行了实验室合成研究,产物经分析测定,与西德苯达松相仿。76年,我省建湖县农药厂与四川化工研究所协作,77年上半年合成苯达松50余公斤,提请14个省、市农科部门进行药效试验。同年接受国家科委下达
Bentazon (also known as Methylprednisolone, Betulacetin) is a high efficiency, low toxicity, low residual new herbicides. West Germany Baden Aniline base company successfully developed in 1968. The United States, Japan and other countries have introduced the technology. In 1975, Sichuan Chemical Research Institute conducted a laboratory synthesis study, the product was analyzed and determined, and West Germany similar to bentazon. In 1976, Jianhu County Pesticide Factory cooperated with Sichuan Chemical Research Institute to synthesize up to 50 kg of bentazon in the first half of 77 and drew 14 provincial and municipal agricultural departments for efficacy test. The same year the State Science Commission issued
