Embodiment 1

[0025] Example 1: 21% flucarbazone-flufenacet oil suspension

[0026] The components of the pesticide composition containing flucarbasulfuron-methyl and flufenacet are: flucarbasulfuron-methyl 1%, flufenacet 20%, sodium lauryl sulfate 2%, sodium butylnaphthalenesulfonate 3% %, calcium lignosulfonate 5%, white carbon black 5%, kaolin to 100%.

[0027] 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, a 21% flucarbazone-methyl-flufenacet oil suspension can be made.

Embodiment 2

[0028] Example 2: 16% flucarbazone-flufenacet suspension concentrate

[0029] The components of the pesticide composition containing flucarbasulfuron-methyl and flufenacet are: flucarbasulfuron-methyl 1%, flufenacet 15%, phenethylphenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, ethylene glycol 5%, magnesium aluminum silicate 2%, defoamer 0.5%, preservative 0.1%, xanthan gum 0.1%, water to 100%.

[0030] 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 98% pass through 1-5um and discharge. The material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. After emulsification, it can be made into 16% flucarbasulfuron-flufenacet suspension .

Embodiment 3

[0031] Example 3: 17% flucarbazone-flufenacet oil suspension

[0032] The components of the pesticide composition containing flucarbasulfuron-methyl and flufenacet are: flucarbasulfuron-methyl 2%, flufenacet 15%, phenethylphenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxidized soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0033] 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, 17% flucarbasulfuron-flufenacet oil suspension can be made.

Abstract

The invention discloses a pesticide composition containing flucarbazone and flufenacet and application of the pesticide composition. Active components of the pesticide composition are the flucarbazone and the flufenacet, wherein the mass ratio of the flucarbazone to the flufenacet is (0.5 to 5):(5 to 80). 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, the problems of gramineous weeds and part of broadleaf weeds in the wheat field 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 the gramineous weeds and part of 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 and flufenacet for controlling gramineous and some 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. However, the serious occurrence of...
