Embodiment 1

[0026] Embodiment 1: 47% chlorotoluron, pretilachlor and diflufenamide microemulsion

[0027] The components of the pesticide composition containing chlortoluron, pretilachlor and diflufenamide are: 15% of chlorotoluron, 30% of pretilachlor, 2% of diflufenamide, 5% of xylene, Hexanone 8%, nonylphenol ethoxylate 5%, water to make up 100%

[0028] After pretilachlor is adsorbed and mixed with the filler, 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 98 %After passing 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, 47% chloromyron, pretilachlor, and diflufenamide oil can be made suspending agent.

Embodiment 2

[0029] Example 2: 57% Chryromyron · Pretilachlor · Diflufenamide Suspension Concentrate

[0030] The components of the pesticide composition containing chlortoluron, pretilachlor and diflufenamide are: 15% of chlorotoluron, 40% of pretilachlor, 2% of diflufenamide, phenethylphenol polyoxygen Vinyl 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%.

[0031] After pretilachlor 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. 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 xanthan gum. After emulsification, it can be made into 57% chloromyron, pretilachlor, and di...

Embodiment 3

[0032] Example 3: 67% chlorotoluron·pretilachlor·diflufenamide wettable powder

[0033] The components of the pesticide composition containing chlortoluron, pretilachlor and diflufenamide are: 25% of chlorotoluron, 40% of pretilachlor, 2% of diflufenamide, sodium lauryl sulfate 2%, sodium butylnaphthalene sulfonate 3%, calcium lignosulfonate 5%, white carbon black 5%, kaolin to 100%.

[0034] After adsorbing and mixing pretilachlor with the filler, put it into the conical mixer together with the other above-mentioned materials and mix evenly, and then pulverize through the jet mill, and then mix the pulverized material through the conical mixer. The fineness of the mixed material is 98 % Pass through a 325-mesh standard sieve to obtain 67% chlorotoluron·pretilachlor·diflufenamide wettable powder.

Abstract

The invention discloses an herbicide composition containing chlortoluron, pretilachlor and diflufenican and a use thereof. Active components of the herbicide composition comprise chlortoluron, pretilachlor and diflufenican. A mass ratio of chlortoluron, pretilachlor to diflufenican is 10-150: 10-50: 1-50. The herbicide composition has obvious synergism in the above ratio range, reduces an herbicide use dosage, reduces herbicide use frequency, reduces an herbicide use cost, reduces the unfavorable influence produced by the herbicide on an ecological environment and enlarges a weeding spectrum. Through one herbicide use step, various weed problems are solved and defects and limitation of single-ingredient herbicide use are overcome. The herbicide composition prolongs a service life and has an important meaning for comprehensive control of weed resistance. The herbicide composition can fast produce effects, has long action time, has a low use cost and can be used for preventing and controlling gramineous weeds and broadleaf weeds in a wheat field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing chlorotoluron, pretilachlor and diflufenac, which is used for controlling grass weeds and broad-leaved weeds in wheat (barley) 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. China's wheat planting area and output rank first in the world, and it is the world's largest wheat producer and consumer. However, weed damage has always been one of the limiting factors for high yi...
