Embodiment 1

[0025] Example 1: 22% Difenpyr-Flufenacet Oil Suspension Concentrate

[0026] The components of the pesticide composition containing fenfenpyr and flufenacet are: fenfenpyr 7%, flufenacet 15%, phenethylphenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxidized soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0027] After absorbing and mixing dipacenil and the filler, add the other above-mentioned materials (except organic bentonite) into the reaction kettle 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, a 22% dipoxenil-flufenacet oil suspension can be made.

Embodiment 2

[0028] Example 2: 30% Difenpyr-Flufenacet Suspension Concentrate

[0029] The components of the pesticide composition containing fenfenpyr and flufenacet are: fenfenpyr 5%, flufenacet 25%, 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 absorbing and mixing dipacenil and the filler, add the other above-mentioned materials (except xanthan gum) into the reactor mixer together, stir evenly, inject the materials into the multi-stage sand mill for grinding, and the ground materials are fine 98% pass through 1-5um and discharge the material. The material is put into a high-shear emulsification kettle together with the pre-dissolved xanthan gum. After emulsification, it can be made into a 30% difenpyr-flufenacet suspension .

Embodiment 3

[0031] Example 3: 34% bisacenil·flufenacet wettable powder

[0032] The components of the pesticide composition containing fenfenpyr and flufenacet are: 18% fenfenpyr, 16% flufenacet, 2% sodium lauryl sulfate, and 3% sodium butylnaphthalene sulfonate %, calcium lignosulfonate 5%, white carbon black 5%, kaolin to 100%.

[0033] After absorbing and mixing the bisacenil filler, put it into the conical mixer together with the other above-mentioned materials and mix evenly, and then pulverize it through the jet mill, and then mix the pulverized material through the conical mixer. The fineness of the mixed material is 98 % Pass through a 325-mesh standard sieve to obtain 34% dipacenil-flufenacet wettable powder.

Abstract

The invention discloses a pesticide composition containing pyraclonil and flufenacet and application of the pesticide composition. The active ingredients of the pesticide composition are pyraclonil and flufenacet, and the mass ratio of the pyraclonil to the flufenacet is (5-25):(2-50). The pesticide composition shows an obvious synergistic effect in the ratio range, the dosage of a pesticide is reduced, the times for using the pesticide are reduced, the adverse effect of the pesticide on the ecological environment is reduced, the herbicide controlling spectrum is expanded, various weed problems are solved by using the pesticide once, the defects and the limits of single dosage are overcome, the service life of the pesticide is prolonged, the pesticide composition is of great significance for the comprehensive treatment of the weed resistance, the pesticide effect is achieved rapidly, the persistent period is long, the use cost is low, and the pesticide composition can be used to prevent and control grassy weeds, broadleaf weeds and sedge family weeds in a paddy field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing fenfenpyr and flufenacet for controlling weeds in paddy fields. Background technique [0002] The annual loss of world crop production due to weed damage is about 11%. Weed damage has seriously affected the quality and yield of crops, and is a key factor restricting crop yield. 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. However, the serious occurrence of weed damage in paddy fields is the main obstacle restricting its high and stable yield. The use of chemical herbicides is one of the important symbols of modern agriculture. In recent years, the application area of ​​herbicides has expanded year by year, and the proportion of pesticide sales has increased year by year. At present, the c...
