Example Embodiment
[0020] Example 1
[0021] A herbicide composition comprising three active ingredients of fluroxypyr, metolachlor and cyprozinone, wherein the proportion of each active ingredient to the total weight is: chlorine Fluroxyacetic acid: 30%; metolachlor; 22%; cyprozinone: 13%.
[0022] The herbicide also contains a dispersant, a surfactant, a solvent, a defoamer, and a safener, the safener is chloridin, the surfactant is a fatty alcohol polyoxyethylene ether sodium sulfate, and the herbicide The dosage form of the composition is emulsifiable concentrate.
Example Embodiment
[0023] Example 2
[0024] A herbicide composition comprising three active ingredients of fluroxypyr, metolachlor and cyprozinone, wherein the proportion of each active ingredient to the total weight is: chlorine Fluroxyacetic acid: 38%; Metolachlor; 18%; Cyclozinone: 9%.
[0025] The herbicide also contains a dispersant, a surfactant, a solvent, a defoamer, and a safener, the safener is chloridin, the surfactant is sodium dodecylbenzene sulfonate, and the herbicide The dosage form of the composition is a suspension.
Example Embodiment
[0026] Example 3

Abstract
The invention provides a weed killer composition.The weed killer composition is characterized by comprising three active ingredients of fluroxypyr, metolachlor and hexazinone, and fluroxypyr, metolachlor and hexazinone account for 30-50%, 18-25% and 9-15% of the total weight respectively.Fluroxypyr, metolachlor and hexazinone are compounded according to a certain ratio to form the weed killer composition, the three ingredients interact after being mixed, the obtained weed killer composition is beneficial for forming weed resistance, and weed killing activity of the weed killer is greatly improved; the three raw materials are mixed and take effect in a complementary mode, and the range of the weed killing spectrum is enlarged; compared with single agents containing the active ingredients, production and use cost is reduced, and cost of using the weed killer is saved for farmers.
Description
technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicide composition. Background technique [0002] Weeds are considered to be one of the main enemies that seriously damage crops. There are more than 30,000 kinds of weeds widely distributed in the world, and about 1,800 kinds of weeds cause different degrees of damage to crops every year, resulting in a crop yield reduction of up to 9.7%. In recent years, with the adjustment of the planting structure and the change of the farming system, especially the continuous use of chemical herbicides, the existing single-dose and compound herbicides have poor safety, or the weeding effect is not high, or the cost of use is high, or the use of Shortcomings such as a narrow range have led to the disappearance of sensitive weeds and the survival and reproduction of drug-resistant weeds. The problem of weed resistance to herbicides in farmland in my country has begun to emerge. In ord...
