Embodiment 1）

[0024] The dosage form of the cornfield herbicide composition of the present embodiment is a wettable powder, which is composed of the following components by weight: 12 parts by weight of carfentrazone-ethyl, 3 parts by weight of pyrazosulfuron-methyl, 2 parts by weight of Polyoxyethylene polyoxypropylene block copolymer as a wetting agent, 3 parts by weight of lignosulfonate as a dispersant, 70 parts by weight of kaolin as a carrier, and 10 parts by weight of white carbon black as a carrier. The parts by weight of each component listed above are also called formulas. In the above components, both carfentrazone-ethyl and chlorpyrazosulfuron-methyl are active components, and the wetting agent and the dispersing agent are both auxiliary agents.

[0025] The above-mentioned carfentrazone-ethyl and chlorpyrazosulfuron-methyl as the active components are all from Jiangsu Agricultural Hormone Engineering Technology Research Center Co., Ltd., and the purity meets the relevant qualit...

Embodiment 2）

[0028] The dosage form of the cornfield herbicide composition of the present embodiment is still a wettable powder, and the rest of the wettable powder is the same as in Example 1, except that the proportion of each component described is: 15 parts by weight of carfentrazone-ethyl, 15 parts by weight of chlorpyrazosulfuron-methyl, 2 parts by weight of polyoxyethylene polyoxypropylene block copolymer as a wetting agent, 4 parts by weight of lignosulfonate as a dispersant, 50 parts by weight of kaolin as a carrier and 14 parts by weight of white carbon black as a carrier.

[0029] The preparation method is the same as in Example 1.

Embodiment 3）

[0031] The dosage form of the cornfield herbicide composition of the present embodiment is still a wettable powder, and the rest of the wettable powder is the same as in Example 1, except that each component and the corresponding proportioning are: 10 parts by weight of Profentrazone-ethyl, 45 parts by weight of pyrazosulfuron-methyl, 15 parts by weight of pyrazone-ethyl as a safener, 4 parts by weight of polyoxyethylene polyoxypropylene block copolymer as a wetting agent, 7 parts by weight Parts of lignosulfonate as a dispersant and 19 parts by weight of white carbon black as a carrier.

[0032] The above-mentioned pyraclofen-ethyl as a safener comes from Jiangsu Agricultural Hormone Engineering Technology Research Center Co., Ltd.

[0033] The preparation method is as follows: according to the above formula, coarsely pulverize the active component chlorpyrazosulfuron-methyl into a powdery object with a particle size ≤ 420 microns for use; , the auxiliary agent and the safen...

Abstract

The invention discloses a corn field herbicide composition, which comprises an active ingredient, an auxiliary agent and a carrier, wherein the active ingredient consists of carfentrazone-ethyl and halosulfuron-methyl, the weight ratio of the carfentrazone-ethyl to the halosulfuron-methyl is 1:50-50:1, and the weight of the active ingredient is 1 to 90 percent of the total weight of the composition. The formulation of the composition is wettable powder, water dispersible granules or suspension. The corn field herbicide composition has the advantages of wide weeding spectrum, high activity, low toxicity, low cost, synergism and the like.

Description

technical field [0001] The invention relates to a herbicide, in particular to a cornfield herbicide composition. Background technique [0002] With the development of industrialization and the demand for feed, my country's demand for corn is gradually increasing. In 2007, the planting area of ​​corn in my country has surpassed that of rice, becoming the crop with the largest planting area in my country. The geographical distribution of corn planting in my country is very extensive, from Taiwan and coastal provinces in the east, to Xinjiang and the Tibetan Plateau in the west, from Hainan Island at 18 degrees north latitude in the south, to the north of Heihe River at 53 degrees north latitude in the north. It is very complicated. The grass weeds mainly include barnyard grass, goosegrass, crabgrass, foxtail, etc. The broad-leaved weeds mainly include purslane, retroverted amaranth, amaranth, velvetleaf, cocklebur, quinoa, etc. Grass weeds such as Cyperus Cyperi etc. The herb...
