Embodiment 1

[0026] Example 1: 22% flucarbazone-methyl-flufenacet-flufenacet-flufensulam oil suspension concentrate

[0027] The components of the pesticide composition containing flucarbasulfuron-methyl, flufenacet and florasulam are: flucarbasulfuron 1%, flufenacet 20%, flufenacet 1%, phenethyl Phenyl phenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxy soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0028] After absorbing and mixing flufenacet with the filler, add the other above-mentioned materials (except organic bentonite) into the reactor mixer, stir evenly, and inject the materials into the multi-stage sand mill for grinding. The fineness of the ground materials is After 98% pass through 1-5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, 22% flucarbazone-methyl-flufenacet-difluorosulfuron Grass Ammonium Oil Suspension Concentrate.

Embodiment 2

[0029] Example 2: 17% flucarbazone-methyl-flufenacet-flufenacet suspension concentrate

[0030] The components of the pesticide composition containing flucarbasulfuron-methyl, flufenacet and florasulam are: flucarbasulfuron 1%, flufenacet 15%, flufenacet 1%, phenethyl 5% phenol polyoxyethylene ether, sodium lignosulfonate 8%, ethylene glycol 5%, magnesium aluminum silicate 2%, defoamer 0.5%, preservative 0.1%, xanthan gum 0.1%, water to 100 %.

[0031] After flufenacet is adsorbed and mixed with the filler, other above-mentioned materials (except xanthan gum) are added to the reactor mixer together, stirred evenly, and the materials are injected into a multi-stage sand mill for grinding, and the ground materials are fine The material is discharged after passing through 1-5um with a density of 98%. The material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. Flusulam suspension concentrate.

Embodiment 3

[0032] Example 3: 18.5% flucarbasulfuron · flufenacet · florasulam wettable powder

[0033] The components of the pesticide composition containing flucarbasulfuron-methyl, flufenacet and florasulam are: flucarbasulfuron 2%, flufenacet 15%, flufenacet 1.5%, 12 Sodium alkyl sulfate 2%, sodium butyl naphthalene sulfonate 3%, calcium lignosulfonate 5%, white carbon black 5%, kaolin to 100%.

[0034] After absorbing and mixing flufenacet with the filler, put it into the conical mixer together with other above-mentioned materials and mix evenly, and then pulverize through the jet mill, and then mix the pulverized material through the conical mixer, and the fineness of the mixed material is 98% passed through a 325-mesh standard sieve to obtain 18.5% flucarbazone-flufenacet-flufenacet wettable powder.

Abstract

The invention discloses a pesticide composition containing flucarbazone, flufenacet and florasulam and application of the pesticide composition. Active components of the pesticide composition are the flucarbazone, the flufenacet and the florasulam, wherein the mass ratio of the flucarbazone to the flufenacet to the florasulam is (0.5 to 5):(5 to 80):(0.1 to 3). According to the pesticide composition, a remarkable synergistic effect within the proportioning range is shown, the using dose of pesticide is reduced, application times of the pesticide are reduced, the pesticide use cost is reduced, and adverse influence of pesticide on an ecological environment is reduced; a weeding spectrum is enlarged, and by one-time pesticide application, various weed problems are solved, and the defects and the limitation of single-dose use are made up; the service life of the pesticide is prolonged, and important significance for integrated management of weed resistance is realized. The pesticide composition is quick in pesticide efficiency playing, long in duration and low in use cost, and can be used for controlling gramineous weeds and broadleaf weeds in the wheat field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing flucarbasulfuron-methyl, flufenacet and florasulam, which is used for controlling gramineous weeds and broad-leaved weeds in wheat fields. Background technique [0002] According to statistics, the world's grain production loses 14% every year due to diseases, insects, and weeds, and the loss caused by weeds is about 11%. Weed damage is a key factor restricting crop production. The use of chemical herbicides is one of the important symbols of modern agriculture. In recent years, sales of herbicides have increased year by year, accounting for an increasing proportion of pesticide sales, and the application area has expanded year by year. Wheat is the crop with the largest consumption, the largest planting area, the largest total output, and the highest per unit yield in China, and it has an important position in the world. Howeve...
