Embodiment 1

[0031] Embodiment 1: 38% quinclorac Tribesulfuron oil suspension concentrate

[0032] The components of the pesticide composition are: quinclorac 12%, tribenuron-methyl 26%, phenethylphenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, epoxidized soybean oil 5%, organic bentonite 5%, methyl oleate to 100%. After the quinclorac is adsorbed and mixed with the filler, the 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, and 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 38% quinclorac-tribesulfuron oil suspension can be made.

[0033] Tribesulfuron-methyl in this example can be replaced by bensulfuron-methyl, thifensulfuron-methyl, thionsulfuron-me...

Embodiment 2

[0034] Embodiment 2: 38% quinclorac Bensulfuron-methyl suspension concentrate

[0035] The components of the pesticide composition are: quinclorac 19%, bensulfuron-methyl 19%, phenethylphenol polyoxyethylene ether 5%, sodium lignosulfonate 8%, ethylene glycol 5%, silicon Magnesium aluminum acid 2%, defoamer 0.5%, preservative 0.1%, xanthan gum 0.1%, water to 100%.

[0036] After the quinclorac is adsorbed and mixed with the filler, the 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 The material is discharged after passing through 1-5um with a density of 98%. 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 38% quinclorac-bensulfuron-methyl suspension .

[0037] Bensulfuron-methyl in this example can be replaced...

Embodiment 3

[0038] Embodiment 3: 42% quinclorac · thiazone-methyl wettable powder

[0039] The components of the pesticide composition are: quinclorac 21%, thionsulfuron 21%, sodium butylnaphthalene sulfonate 3%, calcium lignosulfonate 5%, white carbon black 5%, kaolin to 100% %.

[0040] After the quinclorac is adsorbed and mixed with 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% passed through a 325-mesh standard sieve to obtain a 42% quinclorac-thiazone-methyl wettable powder.

[0041] The thiazosulfuron-methyl in this example can be replaced by bensulfuron-methyl, thifensulfuron-methyl, tribenuron-methyl or fluroxypyr, and a new example is formed according to the same conditions and formula ratios.

Abstract

The invention discloses a herbicidal composition containing quinclorac or a salt thereof and application of the herbicidal composition. Effective components of the herbicidal composition include a component I and a component II; the component I is the quinclorac or the salt thereof; the component II is tribenuron-methyl, bensulfuron-methyl, thifensulfuron-methyl, thiazone-methyl or fluroxypyr; and the mass ratio of the component I and the component II of the pesticide composition is (1 to 50)-(25 to 1). The invention also discloses a preparation prepared from the composition and suitable for agricultural use and application of the preparation in preventing and controlling broadleaf weeds in wheat field. The pesticide composition containing the quinclorac has obvious synergistic action, lowers the using dosage of a pesticide, reduces the applying times, lowers the applying cost and the adverse effect of the pesticide to ecological environment, expands a weeding spectrum, solves the problems of various broadleaf weeds by being applying for one time, makes up for the defects and the limitation during single dose use, prolongs the service life of a medicament, has important significance on comprehensively treating weed resistance, is rapid in exerting the pesticide effect, long in persistent period and low in use cost and has a wide development and popularization prospect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a pesticide composition containing quinclorac or its salts for controlling broad-leaved weeds in wheat fields. Background technique [0002] In recent years, due to changes in farming and cultivation methods, the weeds and weeds in farmland have changed significantly. At present, the grass phase of broad-leaved weeds in wheat fields has been replaced by the main hazards of shepherd's purse and vetch, to pig's weed, cow chickweed and wild geranium. The chemical herbicides used to control broad-leaved weeds in wheat fields are mainly sulfonylurea herbicides such as tribenuron-methyl and bensulfuron-methyl. Long-term single and continuous use has led to high levels of weed resistance to a single agent of this type of herbicide. sex. The rapid occurrence and spread of weed resistance has led to increasing pesticide costs for farmers, posing a serious threat to the sa...
