Abstract

The invention relates to a stable herbicide composition. The composition consists of two active ingredients A and B. Component A is selected from compounds represented by the following general formula: Component B is selected from glyphosate and its agrochemically applicable salts or esters. When preparing a solid preparation, the active component A is first adsorbed by an adsorption carrier, and the adsorption product is then mixed with component B, auxiliary agents and fillers to obtain a stable solid preparation.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, and relates to a herbicide composition solid preparation and a preparation method thereof. Background technique [0002] Patent WO2016095768 reports isoxazoline-containing uracil compounds as shown in general formula I: [0003] [0004] The compound of general formula I has good herbicidal activity, and can effectively control barnyardgrass, foxtail, heteromorphous sedge, water sedge, crabgrass, weed grass, velvetleaf, zinnia, retroflexus, purslane, Weeds of different leaf stages such as ears, black nightshade, cassia, wild watermelon seedlings, and wild soybeans can achieve good weeding effects at low doses. [0005] Glyphosate, English common name glyphosate, CA registration number: 1071-83-6, chemical name N-(phosphorylmethyl) glycine, N-(phosphorylmethyl) glycine, English chemical name: PhosphonomethylIminoAcetic Acid, molecular formula C 3 h 8 NO 5 P, molecular weight 169.09. ...
