Description
Technical field
It is outstanding more particularly to a kind of dispersible oil containing mesosulfuron and clodinafop-propargyl the invention belongs to technical field of pesticide
Floating agent and preparation method thereof.The dispersible oil-suspending agent is applied to wheat paddock weeding.
Background technology
Wheat is one of main cereal crops in China, and weeding for wheat is a great problem in production.Chemical weed control is mesh
The Main Means of preceding control weeds.In recent years, because some herbicide kind large area are used alone, many weeds are already led to
Generate the resistance to the action of a drug.Simultaneously as mutually complexity, species are various for grass when weeds occur, single variety is used and can not effectively solved
Farmland weed, the defects of showing in a certain respect.Herbicide is wide in variety in the market, while application technology also requires
Height, it is careless slightly in the application, poisoning will occur, the problems such as herbicidal effect is bad.Herbicide will be directly affected from improper
People or the safety or yield of crops.With the development of weeding technique and the emergence of herbicide, many weeds of farmland
Then it is increasingly difficult to kill.
Mesosulfuron (Mesosulfuron-methyl), [3- (4, the 6-=methoxy pyrimidine -2- of chemical name methyl -2
Base) a ureido sulfuryl l-4- methanesulfonylaminobenzene formic acid esters, belong to sulfonylurea highy potent herbicide, mainly pass through plant
Cauline leaf absorbs, and is conducted through bast and xylem, on a small quantity by soil absorption, suppresses the acetolactic acid synthesis in sensitive plant body
The activity of enzyme, cause the numerous sour biosynthesis block of side chain ammonia, so as to suppress cell division, cause sensitive plant dead.Ordinary circumstance
Under, after dispenser 2~4 hours, the uptake of susceptible weeds peaks, and is stopped growing after 2 days, and rear blade starts Huang within 4~7 days
Change, withered spot then occur, it is dead after 2~4 weeks.The safener contained in this product, it can be promoted to be decomposed rapidly in crop body, and
Its degraded in target weeds body is not influenceed, so as to reach the purpose for killing weeds, cover crop.Suitable in soft and
Used in semi-rigid type winter wheat variety.Amur foxtail, wild oat can be prevented and kill off, caput grass, annual bluegrass, hard grass, alkali thatch, spend more rye
The weeds such as grass, lolium temulentum, bromegrass, candle grass, Triticum tauschii, Tong grass, wheatgrass, shepherd's purse, Descurainia sophia, ox chickweed, spontaneous rape.
Clodinafop-propargyl (clodinafop-propargyl), chemical name:R-2- [4- (the fluoro- 2- epoxides pyridines of the chloro- 3- of 5-)-benzene
Epoxide]-propionic acid-propynyl ester, belong to fragrant phenoxy phenoxy propionic acid herbicide, the biosynthesis that can effectively suppress class ester is the auxiliary quick A of acetyl
Hydroxylase inhibitors, are degraded to free acid phenyl quickly in soil and pyridine moiety enters soil.The medicament can prevent and treat wheat
The grassy weeds such as vole tail amur foxtail, tall oat grass, rye grass, rough stalked blue grass green bristlegrass.
The content of the invention
The purpose of the present invention is to be directed to problems of the prior art, a kind of dividing containing mesosulfuron and clodinafop-propargyl
Dissipate oil-suspending agent and preparation method thereof, there is provided a kind of component is reasonable, and herbicidal spectrum is wide, and preventive effect is good, and drug cost is low, is not likely to produce anti-
A kind of dispersible oil-suspending agent containing mesosulfuron and clodinafop-propargyl of the property of medicine.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
A kind of dispersible oil-suspending agent containing mesosulfuron and clodinafop-propargyl, the dispersible oil-suspending agent include effectively living
Property composition mesosulfuron and clodinafop-propargyl；The mesosulfuron and the mass ratio of clodinafop-propargyl are (0.01%~1%)：(21%
~50%).
Preferably, a kind of described dispersible oil-suspending agent containing mesosulfuron and clodinafop-propargyl includes mesosulfuron
