日本 Sagami 化学研究中心、Chisso公司和 Keken 制药公司共同研制出新型的对多种杂草均有杀除能力的除莠剂。它是以新型恶唑烷为基础制备的,对阔叶类等杂草显示广谱除莠能力,而对庄稼毒性甚低。其显著特点是对有用植物产生选择性,即对丛生于大豆和其它豆类及玉米、水稻等谷物田中的许多主要阔叶杂草加以杀除。其中有一种化合物还可做为无选择性除莠剂而广泛使用于耕地和免耕地。这三家公司不久将进行慢性毒性实验,并计划5年内制出商品。
Japan Sagami Chemical Research Center, Chisso Corporation and Keken Pharmaceutical Company jointly developed a new variety of weeds have killing ability of herbicides. It is based on the new oxazolidine-based, broad-spectrum herbicidality for broad-leaved weeds and other crops, and very low toxicity to crops. Its salient features are the selectivity of useful plants, that is, the killing of many of the major broadleaf weeds that colonize soybeans and other legumes and cereal fields such as corn and rice. One of these compounds is also widely used as a non-selective herbicide for arable land and no-till. The three companies will soon conduct chronic toxicity experiments and plan to produce products within five years.
