Embodiment 1）

[0028] The dosage form of the herbicidal composition of the present embodiment is a wettable powder, which is composed of the following components by weight: 8 parts by weight of chlorpyrazosulfuron-methyl, 8 parts by weight of oxaziclozone, 2 parts by weight of Fatty alcohol polyoxyethylene ether sodium sulfate as a wetting agent, 1 part by weight of lignosulfonate as a dispersant, and 81 parts by weight of kaolin as a solid carrier.

[0029] The above-mentioned chlorpyrazosulfuron-methyl and oxazicone as the active components are all from Jiangsu Agricultural Hormone Engineering Technology Research Center Co., Ltd., and the purity meets the relevant quality requirements. The above-mentioned sodium fatty alcohol polyoxyethylene ether sulfate used as a wetting agent is sodium lauryl alcohol polyoxyethylene ether sulfate, which comes from Japan Takemoto Oil Co., Ltd., and the product code is Pionin A-28. The above-mentioned lignosulfonate used as a dispersant comes from OMNIChe...

Embodiment 2）

[0032] The dosage form of the herbicidal composition of the present embodiment is still a wettable powder, and the wettable powder is made up of the following components by weight: 8 parts by weight of chlorpyrazosulfuron-methyl, 22 parts by weight of oxaziclodione, 2 parts by weight Parts of sodium fatty alcohol polyoxyethylene ether sulfate as a wetting agent, 2 parts by weight of lignosulfonate as a dispersant, and 72 parts by weight of kaolin as a solid carrier.

[0033] The component source and preparation method of this embodiment are the same as embodiment 1.

Embodiment 3）

[0035] The dosage form of the herbicidal composition of the present embodiment is still a wettable powder, which is composed of the following components by weight: 40 parts by weight of chlorpyrazosulfuron-methyl, 20 parts by weight of oxaziclodione, 4 parts by weight Parts of sodium fatty alcohol polyoxyethylene ether sulfate as a wetting agent, 4 parts by weight of lignosulfonate as a dispersant, and 32 parts by weight of kaolin as a solid carrier.

Abstract

The invention discloses a weeding composition containing halosulfuron-methyl and oxaziclomefone. The weeding composition containing halosulfuron-methyl and oxaziclomefone is composed of an active component, an additive and a carrier, wherein the active component is composed of halosulfuron-methyl and oxaziclomefone in weight ratio of 0.02-50, and the active component accounts for 1-90% of the total weight of the weeding composition. The weeding composition containing halosulfuron-methyl and oxaziclomefone can be the conventional pesticide dosage forms of wettable powder, water dispersible granules, oil suspension, powder, granules, dry suspending agent, emulsion oil, emulsion in water, microemulsion in water, or suspended emulsion and the like. The weeding composition has a synergistic effect and a broad herbicide controlling spectrum, can prevent and kill various weeds in a grass family and a sedge family and broad leaf weeds, including multiple pernicious weeds such as barnyard grass and difformed galingale herb, can be used before and after seedlings grow and is low in dosage and high in safety to crops.

Description

technical field [0001] The invention relates to a herbicide, in particular to a herbicide composition containing chlorpyrazosulfuron-methyl and oxaziculone. Background technique [0002] The chemical name of clopyrazosulfuron-methyl (CAS accession number 100784-20-1) is: 3-chloro-5-(4,6-dimethoxypyrimidin-2-ylaminocarbonylaminosulfonyl)-1- Methylpyrazole-4-carboxylate. The structural formula is as follows: [0003] . [0004] It is a sulfonylurea herbicide, which can be used in various crops and non-crops such as wheat, corn, rice, etc. It has a wide herbicidal spectrum, low dosage, high activity and strong selectivity. However, the requirements for application technology are relatively strict, and improper use can easily cause phytotoxicity, and its price is relatively high. [0005] The chemical name of oxazimidone (CAS accession number 153197-14-9) is: 3-[1-(3,5-dichlorophenyl)-1-methylethyl]-2,3-dihydro -6-Methyl-5-phenyl-4H-1,3-oxazin-4-one. The structural formu...
