Embodiment 1

[0027] Example 1: 27.5% flucarbasulfuron-isoproturon-florasulam oil suspension

[0028] The components of the pesticide composition containing flucarbasulfuron-methyl, isoproturon and florasulam are: flucarbasulfuron-methyl 1%, isoproturon 26%, flucarbazone-methyl 0.5%, phenethylphenol Polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxy soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0029] After adsorption and mixing of isoproturon and filler, add other above-mentioned materials (except organic bentonite) 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 1-5um, the material is discharged, and the material is put into a high-shear emulsification kettle together with the pre-dissolved organic bentonite. After emulsification, 27.5% flucarbazone-methyl-isoproturon-flusulam can be produced oil suspension.

Embodiment 2

[0030] Example 2: 26.5% flucarbasulfuron · isoproturon · florasulam suspension concentrate

[0031] The components of the pesticide composition containing flucarbasulfuron-methyl, isoproturon and florasulam are: flucarbasulfuron 1%, isoproturon 25%, diflurasulam 0.5%, 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 adsorption and mixing of isoproturon and filler, other above-mentioned materials (except xanthan gum) are added into the reactor mixer together, stirred evenly, and the materials are injected into a multi-stage sand mill for grinding, and the fineness of the materials after grinding 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, 26.5% flucarbasulfuron-isoproturon-difluoros...

Embodiment 3

[0033] Example 3: 29% flusasulfuron · isoproturon · florasulam wettable powder

[0034] The components of the pesticide composition containing flucarbasulfuron-methyl, isoproturon and florasulam are: flucarbasulfuron 1%, isoproturon 27%, florasulam 1%, lauryl Sodium sulfate 2%, sodium butylnaphthalene sulfonate 3%, calcium lignosulfonate 5%, white carbon black 5%, kaolin to 100%.

[0035] After adsorption and mixing of isoproturon and 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 98 % Pass through a 325-mesh standard sieve to obtain 29% flucarbasulfuron-isoproturon-flusunacil wettable powder.

Abstract

The invention discloses a pesticide composition containing flucarbazone, isoproturon and florasulam, and an application thereof. The active components of the pesticide composition contain flucarbazone, isoproturon and florasulam according to a mass ratio of 0.5-5:10-80:0.1-3. The pesticide composition has obvious synergism in above ratio range, reduces the use dosage of pesticides, reduces the pesticide use frequency, reduces the pesticide use cost, and reduces untoward influences of pesticides on the ecologic environment; the pesticide composition enlarges the weeding spectrum, solves various weed problems through one-time pesticide application, and makes up the defects and restriction in the use process of single doses; the composition prolongs the service life of medicines, and is of important significance to comprehensively control the resistance of weeds; and the pesticide composition also has the advantages of rapid pesticide effect performance, long persistent period, and low use cost, and can be used to control the gramineous weeds and parts of broad leaved weeds in wheat fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing flucarbasulfuron, isoproturon 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...
