Embodiment Construction

[0044] The following examples do not limit the present invention, but are only used to illustrate how the present invention is realized. For certain weeds, the examples showed particularly marked effectiveness. Examples are as follows:

[0045] Drug efficacy test:

[0046] 1), the test target:

[0047] Maijiagong, beef chickweed, Baogai grass, sweet sausage, wild carrot, coriander chrysanthemum, and blue cabbage.

[0048] 2), reagents:

[0049] Required active ingredient A: Cycloflumetrione, bisflumezone, fenflurzone, triazole sulfotrione, Produced by our company, others purchased by reagent companies. The original medicines all use acetone as a solvent, and are diluted with an aqueous solution of 0.1% emulsifier Tween-80, and are diluted immediately after use.

Abstract

The invention belongs to the field of pesticides, and particularly relates to a binary weeding composition and application thereof. The binary weeding composition comprises an active component A and an active component B with effective weeding amounts, the active component A is bicyclopyrone, dicarfentrazone-ethyl, topramezone and triazole sulcotrione, and the active component B is selected from one of the following compounds and acids / salts / esters thereof: cinmethylin, trifludimoxizin, indazim, tetflupyrolidine, dichloroclomazone, dimesulfazet, epofenacil and cyclopyrimorate. The composition can effectively prevent and eliminate various weed problems, and has the characteristics of expanding the weed control spectrum, reducing the application amount, generating a synergistic effect, solving resistant weeds and the like.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a binary herbicidal composition and its application. Background technique [0002] Chemical herbicide is the most economical and effective means of controlling weeds in farmland, but long-term continuous high-dose use of a single species or single mode of action of chemical herbicides is likely to cause problems such as weed resistance and resistance evolution. Reasonable compounding or mixing of herbicide compounds has the advantages of expanding the spectrum of weeds, improving the control effect, delaying the occurrence and development of weed resistance and drug resistance, and is one of the most effective methods to solve the above problems. Therefore, there is an urgent need to develop herbicidal composition varieties with high safety, wide herbicidal spectrum, synergistic effect and solving the problem of resistant weeds in production.
