Embodiment 1

[0025] Embodiment 1: 20% flufenacet pendimethalin oil suspension

[0026] The components of the pesticide composition containing flufenacet and pendimethalin are: flufenacet 4%, pendimethalin 16%, phenethylphenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxidized soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0027] After absorbing and mixing flufenacet with the filler, add the other above-mentioned materials (except organic bentonite) into the reactor mixer, stir evenly, and inject the materials into the 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 organic bentonite. After emulsification, 20% flufenacet pendimethalin oil suspension can be made.

Embodiment 2

[0028] Example 2: 25% flufenacet pendimethalin suspension

[0029] The components of the pesticide composition containing flufenacet and pendimethalin are: flufenacet 6%, pendimethalin 19%, 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%.

[0030] After flufenacet 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, and the ground materials are fine 98% pass through 1-5um and discharge. The material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. After emulsification, it can be made into 25% flufenacet pendimethalin suspension .

Embodiment 3

[0031] Example 3: 45% flufenacet pendimethalin wettable powder

[0032] The components of the pesticide composition containing flufenacet and pendimethalin are: flufenacet 10%, pendimethalin 35%, sodium lauryl sulfate 2%, sodium butylnaphthalene sulfonate 3% %, calcium lignosulfonate 5%, white carbon black 5%, kaolin to 100%.

[0033] After the flufenacet filler is adsorbed and mixed, 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 45% flufenacet pendimethalin wettable powder.

Abstract

The invention discloses a pesticide combination containing flufenacet and pendimethalin and an appliance thereof, wherein active ingredients of the pesticide combination are the flufenacet and the pendimethalin, the quality radio of the flufenacet and the pendimethalin is 2-100:5-100. The pesticide combination containing the flufenacet and the pendimethalin obviously shows obvious synergistic effects in the proportion range, reduces dosage, reduces use times, reduce use cost, reduces adverse effect to ecological environment, enlarges a weed control spectrum, solves a lot of weed problems at one time, also makes up defects and limitations when using a single dosage, prolongs service life, has important significance in comprehensive treatment of weed resistance, is rapid to play pesticide effect, long in lasting period and low in use cost, and can be used to prevent wheat paddock gramineae weeds and broadleaf weeds.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing flufenacet and pendimethalin for controlling gramineous weeds and broad-leaved weeds in wheat fields. Background technique [0002] 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. As the second largest food crop in my country, wheat has an important position in the world. But serious weed damage restricts the high and stable yield of wheat. At present, the chemical control of weeds in wheat fields is still dominated by aryloxyphenoxypropionate and sulfonylurea herbicides, which have high costs, unstable efficacy, insignificant benefits, and frequent phytotoxicity accidents And other issues. At the same time, the lo...
