Embodiment 1

[0027] Example 1: 36% Isoproturon · Flufenacet · Flufenacet Oil Suspension Concentrate

[0028] The components of the pesticide composition containing isoproturon, flufenacet and florasulam are: isoproturon 15%, flufenacet 20%, florasulam 1%, phenethylphenol Polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxy soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0029] 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, it can be made into 36% isoproturon, flufenacet, and diflusulfuron Amine oil suspension.

Embodiment 2

[0030] Example 2: 38% Isoproturon · Flufenacet · Flufenacet Suspension Concentrate

[0031] The components of the pesticide composition containing isoproturon, flufenacet and florasulam are: isoproturon 22%, flufenacet 15%, florasulam 1%, 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%.

[0032] 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. After emulsification, 38% isoproturon, flufenacet, and difluoro Sulfonamide Suspension Concentrate...

Embodiment 3

[0033] Example 3: 41.5% Isoproturon · Flufenacet · Flufenacet WP WP

[0034] The components of the pesticide composition containing isoproturon, flufenacet and florasulam are: isoproturon 25%, flufenacet 15%, florasulam 1.5%, lauryl Sodium sulfate 2%, sodium butylnaphthalene sulfonate 3%, calcium lignosulfonate 5%, white carbon black 5%, kaolin to 100%.

[0035] 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 A 41.5% wettable powder of isoproturon, flufenacet, and florasulam was obtained by passing 98% through a 325-mesh standard sieve.

Abstract

The invention discloses a pesticide composition containing flufenacet, isoproturon and florasulam, and application thereof. The pesticide composition comprises active ingredients, namely flufenacet, isoproturon and florasulam at a mass ratio of (10-80) to (5-80) to (0.1-3). The pesticide composition has an obvious synergistic effect within the range of such as mass ratio, the pesticide dosage is reduced, the pesticide use frequency is reduced, the pesticide cost is lowered, and negative influence of the pesticide on ecological environment is reduced; the weeding spectrum is enlarged, various weed problems can be used by using the pesticide once, and the defects and limitations of a single preparation are overcome; the service life of the pesticide composition is prolonged, and the pesticide composition has great significance in comprehensive control on weed resistance, is rapid in pesticide effect exertion and long in durable, is lowered in use cost and is capable of preventing and controlling gramineous weeds and 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 isoproturon, 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. However, the serio...
