Embodiment 1）

[0025] 29% Memetrazone · Beetan · Beetenin Oil Suspension Concentrate: Promethenone 15%, Beetenin 7%, Beetenin 7%, Phenethylphenol Polyoxyethylene Ether 5%, Sodium Lignosulfonate 8 %, epoxy soybean oil 5%, organic bentonite 5%, methyl oleate to 100%.

[0026] After mixing Beet Ann and solvent methyl oleate, add other materials (except organic bentonite) into the reaction kettle mixer, stir evenly, and inject the materials into a multi-stage sand mill for grinding. The fineness of the ground materials is 98% pass through 1-5μm and discharge. The material is put into the high-shear emulsification kettle together with the organic bentonite dissolved in advance. .

Embodiment 2）

[0028] 39% Promethenone · Beetan · Beetenin water suspension concentrate: Promethenone 25%, Beetenin 7%, Beetenin 7%, 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 sugar beets with water, add other materials (except xanthan gum) into the reaction kettle mixer, stir evenly, and inject the materials into a multi-stage sand mill for grinding. The fineness of the ground materials is 98%. After 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, it can be made into a 39% promethazone·betainen·betainin water suspension concentrate.

Embodiment 3）

[0031] 49% Promethenone · Beetan · Beetenin wettable powder: 35% Promethenone, Beetenin 7%, Beetenin 7%, Sodium Lauryl Sulfate 2%, Sodium Butyl Naphthalene Sulfonate 3%, Calcium lignosulfonate 5%, white carbon black 5%, kaolin to 100%.

[0032] Adsorption and mixing of beets and fillers, and other materials are added to the conical mixer and mixed evenly, and then pulverized by the jet mill, and the pulverized materials are then mixed by the conical mixer, and the fineness of the mixed materials is 98%. A 325-mesh standard sieve promptly produced 49% promethazone·beetan·beetenin wettable powder.

Abstract

The invention discloses a pesticide composition containing metamitron, desmedipham and phenmedipham, and application thereof. The pesticide composition comprises active components of the metamitron, the desmedipham and the phenmedipham in the weight ratio of is 10-300 to 2-30 to 2-30. The pesticide composition has a remarkable synergistic effect within the proportion range, the preventing and removing effects are obviously improved by compared with those of the single agent, the dosage, the medication times and the medication cost of the pesticide are reduced, and advertise influences of the pesticide on the ecological environment are reduced. The pesticide composition can effectively prevent grassy weed and broadleaf weed in the beet field, in particular for weeds such as echinochloa crusgalli, chenopodium glaucum and nightshade, can prolong the service life of the pesticide and has an important 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 fenmetrione, beetalin and beetenin for controlling weeds in sugar beet fields and an application thereof. 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] Sugar beet is one of the main economic crops and also an important raw material for the sugar industry. With the increase of beet planting area, beet production is directly related to the economic benefits of farmers and th...
