Embodiment 1

[0021] 25wt% water dispersible granules

[0022] The formula is composed of: 10wt% of cyhalofop-ethyl, 3wt% of clopyrazosulfuron-methyl, 12wt% of quinclorac, 8wt% of sodium methylnaphthalenesulfonate formaldehyde condensate, 3wt% of polycarboxylate, and 2wt% of urea , xanthan gum 1wt%, kaolin supplemented to 100wt%.

[0023] The preparation method is as follows: after all the materials are mixed uniformly, pulverized by an airflow mill, mixed uniformly again, and then a certain amount of water is added to knead the mixture, extruded and granulated, and dried and sieved to obtain the water-dispersible granules.

Embodiment 2

[0025] 14% dispersible oil suspension concentrate

[0026] The formula is composed of: 5wt% of cyhalofop-ethyl, 3wt% of clopyrazosulfuron-methyl, 6wt% of quinclorac, 4wt% of castor oil polyoxyethylene ether, 6wt% of nonylphenol polyoxyethylene ether, triphenylethyl ether Base phenol polyoxyethylene ether phosphate 3wt%, bentonite 2%, soybean oil supplemented to 100%.

[0027] The preparation method is as follows: put the active ingredient, emulsifier, dispersant and dispersion medium into the stirring tank, after fully stirring, pump it into a high-speed shearing machine for high-speed shearing, and then pump it into a sand mill for full sanding, After the sand mill is qualified, add a thickener and stir evenly to obtain a dispersible oil suspension.

Embodiment 3

[0029] 20% EC

[0030] The formula is composed of: 10wt% of cyhalofop-ethyl, 2wt% of chlorpyrazosulfuron-methyl, 8wt% of quinclorac, 4wt% of tristyrylphenol polyoxyethylene ether, 5wt% of agricultural milk, sorbitan ester 4wt%, make up to 100% with xylene.

[0031] The preparation method is as follows: put all the materials into the batching kettle, stir and dissolve until completely transparent, and transfer to the storage tank for filling after passing the test.

Abstract

The invention discloses a halosulfuron methyl-containing herbicide composition and application thereof. The halosulfuron methyl-containing herbicide composition is composed of an active component A, an active component B and an active component C, wherein the active component A is aryloxyphenoxy propionic acid, the active component B is halosulfuron methyl and the active component C is quinoline carboxylic acid. The halosulfuron methyl-containing herbicide composition can be applied to controlling hazardous weeds. With three active components compounded, the halosulfuron methyl-containing herbicide composition can comprehensively control rice field weeds.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a herbicidal composition containing chlorpyrazosulfuron-methyl and an application thereof. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, and are used to destroy or inhibit plant growth. Herbicides are widely used in agriculture because of their low cost, high efficiency, easy operation, labor saving, and obvious weed control effect. [0003] Clopyrazosulfuron-methyl is a sulfonylurea herbicide and an inhibitor of acetolactate synthase (ALS enzyme). That is, by inhibiting the ALS enzyme of plants, it prevents the biosynthesis of branched-chain amino acids such as valine, isoleucine, and leucine, and finally destroys protein synthesis, interferes with DNA synthesis, and cell division and growth. It can be absorbed through the roots, stems and leaves of plants. Symptoms of weed phytotoxicity include growth a...
