Abstract

The invention belongs to the field of agricultural herbicides, and relates to a herbicide composition dispersible oil suspending agent and a preparation method thereof. The invention also relates to the use of the dispersible oil suspending agent for preventing unwanted plant growth. The dispersible oil suspending agent comprises the following components in percentage by weight: 0.1-20% of an active component A, 1-60% of an active component B, 1-30% of a surfactant, 0.1-5% of a pH regulator, 0.5-5% of a structure stabilizer, 0-20% of a solvent and the balance of an oil base, wherein the active component A is a compound as shown in a formula I, and the active component B is selected from glyphosate and agrochemically applicable salts or esters thereof. The dispersible oil suspending agent provided by the invention is stable and free of physical unstable phenomena such as creaming and bottom formation during heat storage, and the effective components are not easy to decompose. The herbicide composition disclosed by the invention can be used for preventing and treating various weeds, especially broadleaf weeds such as piemarker and zinnia elegans, and has an excellent prevention effect.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, and relates to a herbicide composition dispersible oil suspension and a preparation method thereof. The invention also relates to the use of the dispersible oil suspension concentrates for preventing unwanted vegetation. Background technique [0002] Patent WO2016095768 reports the isoxazoline-containing uracil compound A as shown in general formula I: [0003] [0004] Compound A of general formula I has good herbicidal activity. [0005] Glyphosate, English name glyphosate, CA registration number: 1071-83-6, chemical name N-(phosphonomethyl)glycine, molecular formula C 3 h 8 NO 5 P, molecular weight 169.09. Glyphosate is a high-efficiency, low-toxicity, broad-spectrum herbicide. It has a systemic conduction effect and a wide herbicidal spectrum. It has control effects on more than 40 families of plants, including monocotyledons and dicotyledons, annuals and perennials, Herbs and ...
