Embodiment 1

[0026] Embodiment 1: 57% isoproturon·pretilachlor·diflufenamide oil suspension concentrate

[0027] The components of the pesticide composition containing isoproturon, pretilachlor and diflufenamide are: isoproturon 15%, pretilachlor 30%, diflufenamide 12%, phenethylphenol polyoxygen Vinyl ether 5%, sodium lignosulfonate 8%, epoxy soybean oil 5%, organic bentonite 5%, methyl oleate to 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, 57% isoproturon, pretilachlor, and diflufenamide oil can be made suspending agent.

Embodiment 2

[0029] Embodiment 2: 67% isoproturon·pretilachlor·diflufenamide suspension concentrate

[0030] The components of the pesticide composition containing isoproturon, pretilachlor and diflufenamide are: isoproturon 15%, pretilachlor 40%, diflufenamide 12%, 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 67% isoproturon, pretilachlor, and diflufenyl Am...

Embodiment 3

[0032] Example 3: 70% isoproturon · pretilachlor · diflufenamide wettable powder

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

[0034] After adsorption and mixing of pretilachlor and the filler, it is added to the conical mixer together with other above-mentioned materials and mixed evenly, and then pulverized by the jet mill, and the pulverized material is then mixed by the conical mixer, and the fineness of the mixed material is 98 % Pass through a 325-mesh standard sieve to obtain 70% isoproturon-pretilachlor-diflufenamide wettable powder.

Abstract

The invention discloses an herbicide composition containing isoproturon, pretilachlor and diflufenican and a use thereof. Active components of the herbicide composition comprise isoproturon, pretilachlor and diflufenican. A mass ratio of isoproturon, pretilachlor to diflufenican is 10-50: 10-50: 1-20. The herbicide composition has obvious synergism in the above ratio range, reduces an herbicide use amount, 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 for a long time, has a low use cost and can be used for preventing and controlling gramineous weeds, broadleaf weeds and cyperaceae weeds in a paddy field and gramineous weeds and broadleaf weeds in a wheat or barley field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a compound containing isoproturon, pretilachlor and diflufenyl, which is used for controlling gramineous weeds, broad-leaved weeds and sedge weeds in rice and wheat (barley) fields. Amine pesticide composition. 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. Rice and wheat are the main food crops in my country and have an important position in the world. However, the serious occurrence of weed damage is the main ...
