Problems solved by technology

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

Embodiment 1

[0021] A herbicide composition, the herbicide composition contains three active components of fluroxyfen, metolachlor and hexazinone, wherein the proportion of each active component to the total weight is: chlorine Fluroxypyr: 30%; Metolachlor: 22%; Hexazinone: 13%.

[0022] Described herbicide also contains dispersant, tensio-active agent, solvent, antifoaming agent, safener, and described safener is fenpyrid, and described tensio-active agent is fatty alcohol polyoxyethylene ether sodium sulfate, and described herbicide The dosage form of the composition is emulsifiable concentrate.

Embodiment 2

[0024] A herbicide composition, the herbicide composition contains three active components of fluroxyfen, metolachlor and hexazinone, wherein the proportion of each active component to the total weight is: chlorine Fluroxypyr: 38%; Metolachlor: 18%; Hexazinone: 9%.

[0025] Described herbicide also contains dispersant, tensio-active agent, solvent, defoamer, safener, and described safener is fenpyrid, and described tensio-active agent is sodium dodecylbenzene sulfonate, and described herbicide The dosage form of the composition is a suspension.

Embodiment 3

[0027] A herbicide composition, the herbicide composition contains three active components of fluroxyfen, metolachlor and hexazinone, wherein the proportion of each active component to the total weight is: chlorine Fluroxypyr: 42%; Metolachlor: 23%; Hexazinone: 13%.

[0028] Described herbicide also contains one or more in dispersant, tensio-active agent, solvent, safener, described safener is fenpyrid, and described tensio-active agent is sodium dodecylbenzene sulfonate, so The dosage form of the herbicide composition is wettable powder.

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...
