Embodiment 1

[0026] Example 1: 11% flucarbasulfuron pinoxaden suspension concentrate

[0027] The components of the pesticide composition containing flucarbasulfuron and pinoxaden are: flucarbasulfuron 1%, pinoxaden 10%, 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%.

[0028] After the pinoxaden and the filler are adsorbed and mixed, the 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 11% flucarbazone-methyl pinoxaden suspension concentrate .

Embodiment 2

[0029] Example 2: 10% flucarbazone-methyl pinoxaden oil suspension concentrate

[0030] The components of the pesticide composition containing flucarbasulfuron and pinoxaden are: flucarbasulfuron 1%, pinoxaden 9%, phenethylphenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxidized soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0031] After the pinoxaden and the filler are adsorbed and mixed, the other above-mentioned materials (except organic bentonite) are added to the reactor mixer together, stirred evenly, and the materials are injected into a 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, 10% flucarbazone-methyl pinoxaden oil suspension can be made.

Embodiment 3

[0032] Example 3: 16% flucarbazone-methyl pinoxaden suspension concentrate

[0033] The components of the pesticide composition containing flucarbasulfuron and pinoxaden are: flucarbasulfuron 1%, pinoxaden 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%.

[0034] After the pinoxaden and the filler are adsorbed and mixed, the 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, 16% flucarbazone-methyl pinoxaden suspension concentrate can be made .

Abstract

The invention relates to a herbicide composition containing flucarbazone and pinoxaden and an application thereof. The mass ratio of flucarbazone to pinoxaden, the active ingredients of the pesticide composition, is (0.5-5) to (1-40). The pesticide composition has the advantages that the pesticide composition shows obvious synergistic effects in the ratio range, thus reducing the dosage of pesticides, the number of pesticide use, the pesticide use cost and the adverse impacts of the pesticides on the ecological environment; as the weed control spectrum is expanded, the problems of grassy weeds and part of broadleaf weeds in wheat fields are solved by using the pesticides once, thus making up for the defects and limitation during single agent use; the service life of the agent is prolonged, which is of important significance to comprehensive treatment of the resistance of the weeds; the pesticide composition takes effect quickly, has long duration, is low in use cost and can be used for controlling the grassy weeds and part of broadleaf weeds in the wheat fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing fluasulfuron-methyl and pinoxaden 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 whea...
