Embodiment 1）

[0025] 22% diflufenic acid flufenacet flufenazole oil suspension: diflufenic acid 5%, flufenacet 15%, flufenazone 2%, phenethylphenol polyoxyethylene 5% ether, 8% sodium lignosulfonate, 5% epoxy soybean oil, 5% organic bentonite, and 100% methyl oleate.

[0026] After mixing flufenacet with the solvent, add other materials (except organic bentonite) into the reactor mixer, stir evenly, and inject the materials into a multi-stage sand mill for grinding. The fineness of the ground materials is 98% After passing through 1-5μm, 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 22% diflufenican, flufenacet, and fluoxasulfuron. oil suspension.

Embodiment 2）

[0028] 57% Diflufenamide · Flufenacet · Flucarbazone Water Suspension Concentrate: Diflufenamide 15%, Flufenacet 40%, Flufenacet 2%, Phenethylphenol Polyoxyethylene Ether 5%, sodium lignosulfonate 8%, ethylene glycol 5%, magnesium aluminum silicate 2%, silicone defoamer 0.5%, preservative 0.1%, xanthan gum 0.1%, water to 100%.

[0029] After mixing flufenacet with water, add other materials (except xanthan gum) into the reactor mixer together, stir evenly, inject the materials into a multi-stage sand mill for grinding, and the fineness of the ground materials is 98 %After passing through 1-5μm, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. After emulsification, 57% diflufenican, flufenacet, and flufenazole can be made Sulfonuron Suspended Concentrate.

Embodiment 3）

[0031] 67% Diflufenamide · Flufenacet · Flufenazone WP: Diflufenamide 25%, Flufenacet 40%, Flufenacet 2%, Sodium Lauryl Sulfate 2 %, sodium butylnaphthalene sulfonate 3%, calcium lignosulfonate 5%, white carbon black 5%, kaolin to 100%.

[0032] After flufenacet is adsorbed and mixed with the filler, it is added to the conical mixer together with other 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 67% diflufenican · flufenacet · flucarbazone wettable powder.

Abstract

The invention discloses a pesticide composition containing diflufenican, flufenacet and flucarbazone-sodium and an application of the pesticide composition. The active ingredients of the pesticide composition are diflufenican, flufenacet and flucarbazone-sodium in the weight ratio being (1-50):(5-80):(0.5-10). The pesticide composition has remarkable synergism in the proportioning range and has a control effect much better than single agents, the dosage of pesticides, use frequency and pesticide costs are reduced, and adverse influences of the pesticides to ecological environment are reduced. The pesticide composition can effectively control grassy weeds and broadleaf weeds in a wheat field, especially amur foxtail, cleavers and other weeds, the service life of the pesticide can be prolonged, and the pesticide composition has great significance in comprehensive treatment on weed resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing diflufenamide, flufenacet and flucarbazone-methyl for controlling 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, of which about 11% is caused by weeds. 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. [0003] As the second largest food crop in my country, wheat has played a vital role in solving the food and clothing problems of the people and in stabilizing society and politics, and has an important position in the world. However, the serious o...
