Abstract
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. Dispersible oil suspension concentrate by weight percentage, active component A 0.1%-20%, active component B 1%-60%, surfactant 1%-30%, pH regulator 0.1-5%, structure stabilizer 0.5%-5%, solvent 0-20%, and the balance is oil base; wherein, the active component A is a compound shown in formula I, and the active component B is selected from glyphosate and its agrochemically applicable salts or ester. The dispersible oil suspending agent provided by the invention is stable, and has no physical instability such as creaming and bottoming during heat storage, and the active ingredients are not easy to decompose. The herbicide composition of the present invention can be used to control various weeds, especially for broad-leaved weeds, such as velvetleaf and zinnia, and has excellent control 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 ...
