1965年开始我们对酰胺类除草剂进行了研究,在对糠酰胺类等化合物进行的除稗筛选中,即已发现抑草胺具有良好的除种性能。以后我们又合成了几十种脂肪酰胺类化合物进行结构与药效的关系研究,企图筛选出一种国内原料丰富和药效高于敌稗的除草剂。事实证明在酰胺类化合物中,敌稗是最好的稻田除稗剂。考虑到敌稗原料丙酸国内短时期内无法解决,而抑草胺的药效相当于敌稗80％,但原料异丁酸国内能充
Starting from 1965 we studied amide herbicides. In the screening of compounds other than furoamide, we have found that acetochlor has good deracoring properties. Later, we also synthesized dozens of fatty amide compounds to study the relationship between structure and efficacy in an attempt to screen out a domestic raw material rich in herbicides and higher efficacy than propanil. It has been proven that propanil is the best rice field barnyardin among amide compounds. Considering propanediol propionate can not be resolved within a short period of time in the country, while the efficacy of acetochlor is equivalent to 80% of propanil, but the raw material isobutyric acid can be filled
