Problems solved by technology

[0005] Due to the special structure of flufenacet raw powder, which contains multiple carbon-fluorine bonds and carbon-nitrogen single and double bonds, the stability in water is poor, especially when the temperature rises, the double bonds are extremely unstable, causing the original drug to decompose. The content of active ingredients decreases, which also leads to a decrease in efficacy

Abstract

The invention belongs to the field of pesticides, and particularly relates to an assistant composition for preparing a suspending agent, a flufenacet water suspending agent and a preparation method thereof. The assistant composition comprises the following components in parts by weight: 5-20 parts of a synergist, 5-15 parts of a wetting dispersant and 1-3 parts of a stabilizer, wherein the synergist is one or a mixture of more of polyether, fatty alcohol ether and organic silicon; the wetting dispersant is one or any combination of more of high-molecular acrylate, polycarboxylate and polyester; and the stabilizer is an EDTA sodium salt. The assistant composition is used for preparing the flufenacet water suspending agent, and the storage stability and the application performance of the preparation are improved, so that the effects of reducing the medication cost, reducing the amount, increasing the efficiency and protecting the environment are achieved.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an auxiliary agent combination for preparing a suspending agent, a flufenacet aqueous suspension and a preparation method thereof. Background technique [0002] Flufenacet is a herbicide developed and invented by Bayer Company of Germany. It belongs to aryloxyacetamide compounds. It mainly works by inhibiting cell division. It is mainly used in corn, wheat, barley, soybean and other crop fields, and can widely control annual Grasses, sedges and some small broadleaf weeds. Flufenacet is mainly used for soil treatment, both before and after emergence. Physical and chemical properties: pure product is white to brown solid; melting point 75-77°C; solubility in water (mg / l, 25°C): 56 (pH4, 7), 54 (pH9), Chinese alias: 4'-fluoro-N- Isopropyl-2-[5-(trifluoroglycoside)-1,3,4-thiadiazo-2-imine]acetamide; 4'-fluoro-N-isopropyl-2-(5-tri Fluoromethyl-1,3,4-thiadiazol-2-yloxy)acetanil...
