Embodiment 1

[0026] Embodiment 1: 47% isoproturon-pretilachlor-chlorpyramid-methyl oil suspension concentrate

[0027] The components of the pesticide composition containing isoproturon, pretilachlor and chlorpyrazosulfuron are: 15% isoproturon, 30% pretilachlor, 2% chlorpyrazosulfuron, 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, 47% isoproturon-pretilachlor-chlorpyrazosulfuron-methyl oil can be made suspending ...

Embodiment 2

[0029] Example 2: 57% Isoproturon Pretilachlor Clopyrazosulfuron Suspension Concentrate

[0030] The components of the pesticide composition containing isoproturon, pretilachlor and chlorpyrazosulfuron are: 15% isoproturon, 40% pretilachlor, 2% chlorpyrazosulfuron, 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, 57% isoproturon, pretilachlor, and clopyrazine can be mad...

Embodiment 3

[0032] Example 3: 67% isoproturon · pretilachlor · chlorpyrazosulfuron wettable powder

[0033] The components of the pesticide composition containing isoproturon, pretilachlor and chlorpyrazosulfuron are: 25% isoproturon, 40% pretilachlor, 2% chlorpyrazosulfuron, 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 67% isoproturon-pretilachlor-clopyrazosulfuron wettable powder.

Abstract

The invention discloses a pesticide composition containing isoproturon, pretilachlor and halosulfuron-methyl and application thereof. The pesticide composition comprises active components including the isoproturon, the pretilachlor and the halosulfuron-methyl, and the mass ratio of the isoproturon to the pretilachlor to the halosulfuron-methyl is (10-50) to (10-50) to (0.5-10). The pesticide composition shows the obvious synergistic effect in a proportion range and the use dosage of a pesticide is reduced; the medicine using times are reduced and the medicine using cost is reduced; adverse effects on an ecological environment caused by the pesticide are reduced. A weeding spectrum is enlarged and the problem of various weeds can be solved by using the medicine for one time; the defects and the limitation of using a single agent are overcome. The service life of the medicine is prolonged and the pesticide composition has very important meanings on comprehensive treatment of the resistance of the weeds. The pesticide composition is rapid in pesticide effect expression, long in lasting period and low in the use cost, and can be used for preventing and treating grassy weeds of paddy fields, broad leaf weeds and cyperaceae weeds.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing isoproturon, pretilachlor and chlorpyrazosulfuron-methyl for controlling gramineous weeds, broad-leaved weeds and sedge weeds in paddy fields . Background technique [0002] According to statistics, the world's grain production loses 14% every year due to diseases, insects, and weeds, of which 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 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...
