Embodiment 1

[0031] Prepare quizalofop-p-ethyl + fensulam (9:3) dispersible oil suspension concentrate, the dispersible oil suspension concentrate herbicidal composition includes the following raw materials in mass percentage:

[0032]

[0033]

[0034] The specific processing steps of the dispersible oil suspension concentrate of the composition are as follows: according to the above formula, quizalofop-p-ethyl, flumesulam, calcium dodecylbenzenesulfonate, fatty alcohol polyoxyethylene ether, castor oil polyoxyethylene Ether, EO / PO block polyether, white carbon black, organic bentonite, and 150# solvent oil are mixed, and then the material is added to the shearing kettle for shearing, and the sheared material is added to the sand mill for sanding. Grind to material particle diameter less than 5 microns, after sand milling, flush shearing machine and sand mill with part solvent oil, and put into shear kettle secondary shearing evenly with sand milled material, make the present inventi...

Embodiment 2

[0036] Example 2: quizalofop-p-ethyl + fensulam (15:1) water suspension concentrate, the contents of each component are as follows:

[0037]

[0038]

[0039] The specific processing steps of the water suspension of the composition are: according to the above ratio, quizalofop-p-ethyl, flumesulam, fatty alcohol polyoxyethylene ether 1%, polycarboxylate, EO / PO Block polyether, xanthan gum, magnesium aluminum silicate, white carbon black, defoamer, sodium benzoate, and deionized water are fully mixed, cut evenly by a shearing machine, and then sanded by a sand mill in the next step. D90 is less than 5 microns, and then rinse the shearing machine and sand mill with the remaining deionized water, and then put it into the shearing kettle together with the sanded material, and cut evenly, that is, the finished product 16% refined quinazolamide water suspension agent.

Embodiment 3

[0041] Quizalofop-p-ethyl + Mesasulam (10:2) wettable powder, the content of each component is as follows:

[0042]

[0043] The specific processing steps of the wettable powder of the composition are as follows: after fully mixing in a stirring mixer according to the above formula, pulverize through an airflow mill, and finally stir evenly through a conical mixer to obtain the finished product 12% quinazolidine. Wet powder.

Abstract

The invention discloses a weeding composition containing quizalofop-p-ethyl and flumetsulam and a preparation method of the weeding composition. The product can disperse an oil suspending agent weeding composition, a water suspending agent weeding composition, a wettable powder weeding composition and a water dispersible granule weeding composition. The active ingredients in the dispersible oil suspending agent weeding composition, the water suspending agent weeding composition, the wettable powder weeding composition and the water dispersible granule weeding composition comprise quizalofop-p-ethyl and flumetsulam, and the mass ratio of quizalofop-p-ethyl to flumetsulam is (5-100): (0.1-10). The herbicidal composition provided by the invention has the advantages that the pesticide effect is improved, the weed resistance is delayed, the service life of each component is prolonged, the herbicidal spectrum is expanded, almost all weeds in the field can be solved by using the herbicidal composition once, the pesticide cost is saved, the time and labor are saved, the safety is high, and the herbicidal composition is high in cost performance, low in toxicity and high in efficiency.

Description

technical field [0001] The invention relates to a herbicide composition for farmland weeds, in particular to a herbicide composition containing quizalofop-p-ethyl and flumesulam and a preparation method thereof. Background technique [0002] In recent years, with the gradual increase in the requirements for the development of new compounds of pesticides, it is necessary to save the cost of drug use while complying with the policy of high selectivity, high safety, and high efficacy. compound use. So as to achieve the purpose of solving this problem. [0003] Quizalofop-ethyl, other names: Jinghe grass gram, NC-302D(+). Its molecular formula is C19H17ClN2O4, chemical name: ethyl (R)-2-[4-(6-chloroquinoxalin-2-yloxy)phenoxy]propionate. Quizalofop-p-ethyl is absorbed through the stems and leaves of weeds, conducts upwards and downwards in the plant body, accumulates in the top and meristems, inhibits the synthesis of fatty acids in cells, and causes the necrosis of weeds. Qu...
