Study of Microbiologic Herbicide 9018

在筛选新农用抗生生素过程中，发现一株编号为９０１８的放线链霉菌，其４个活性组分（Ａ、Ｂ、Ｃ、Ｄ）具有极强的杀草活性。经分离鉴定，确定Ａ、Ｂ、Ｃ为环己铣亚胺类的新化合物。本文阐述了９０１８的发酵、分离、除草活性及安全性方面的研究。

In the screening of agricultural antibiotics process, we found a strain of No9018 streptomyces and separated four substances (A, B, C, D) with herbicide activities, in which A, B, C are belong to the class of cyclo-heximide and D is a new antibiotic. In this paper we reported the research of 9018 about fermentation, isolation, herbicide activities and toxicity.
