Cloransulam comprising an amine and mixing the herbicide imazethapyr and Production Method

The present invention belongs to the technical field of chemical synthesis, to provide a mixture comprising the two active ingredients of herbicides cloransulam amine and imazethapyr, and methods for preparing and applying the admixture herbicide. The mass ratio of admixture cloransulam herbicide imazethapyr amines with 5 to 60: 1-25, the total mass of both the herbicide mass percentage of 6-75%, can controlling grassy weeds in soybean fields and broadleaf weeds. The present invention provides mixed herbicide having a high herbicidal activity, wide herbicidal spectrum, long duration, safe, efficient broad-spectrum, good compatibility with the environment, human and animal safety and many other advantages, is the quality of soybean crop chemical weed agents.
