1980年美国杜帮公司开发了新除草剂绿黄隆,使世界除草剂科学的发展进入了一个新阶段。此化合物活性之高,是历来除草剂品种所无可比拟的。其每公顷活性物质用量以克计算,为2,4—D的百分之一,打破了传统品种的用药量界限,从而使除草剂的发展进入了“超高效”时代,引起了各国农药界人士的兴趣和关注。化学式、理化性质与毒性已进入生产或试生产的磺酰脲类新除草剂品种,除绿黄隆外,尚有甲黄隆、林木隆、稻禾隆等。DPX系列磺酰脲娄新化合物,杜帮公司尚在继续开发中。这类除草剂的化学通式为;
In 1980 the United States Du Bang company developed a new herbicide Green Huanglong, the world herbicide science has entered a new phase. The high activity of this compound is unmatched by herbicide varieties. The amount of active material per hectare in grams, which is one percent of 2,4-D, broke the traditional varieties of dosage limits, so that the development of herbicides into the “super-efficient” era, causing the pesticide community in various countries People’s interests and concerns. Chemical formula, physical and chemical properties and toxicity Has entered the production or trial production of new varieties of sulfonylurea herbicide, in addition to green Huanglong, there are jiahuanglong, Linlong, rice Wo Long and so on. DPX series sulfonylureas new compounds, Du Bang company is still under development. The chemical general formula of this kind of herbicide is;
