Description
Technical field
The invention belongs to herbicide technology field is and in particular to a kind of pair of fluorine clodinafop-propargyl oil-suspending agent.
Background technology
Florasulam is triazolopyrimidine sulfonamides superelevation effective herbicide, and florasulam is inner sucting conduction type weeding
Agent, can conduct to weeds Herb, thus herbicide is thoroughly, will not recur.Efficacy stability at low temperature, even when 2 DEG C still
Can guarantee that stable drug effect, this point is that other herbicides are incomparable.Prevent and kill off broad leaved weed for wheat paddock.Import 5% pair
Penoxsulam SC, trade name Puri wheat.Florasulam broad weed-killing spectrum, can prevent and kill off the most of broad leaved weed of wheatland, including pig calamity
Calamity (Rubiaceae), the difficult anti-weeds such as corn gromwell (Boraginaceae), and the Herba Euphorbiae Helioscopiae (Euphorbiaceae) being most difficult in wheatland prevent and kill off is had very good
Inhibitory action.
Clodinafop-propargyl, also known as alkynes oxalic acid, chemical name：R-2- [4- (the chloro- 3- of 5- fluoro- 2- pyridyloxy)-phenoxy group]-propanoic acid alkynes
Propyl diester.It is mainly used in the wheatland grass family such as Control Wild oat, amur foxtail, Herba bromi japonici, rye grass, rough stalked blue grass, Herba Setariae Viridis miscellaneous
Grass.Clodinafop-propargyl is the chiral fluorine-containing high-efficiency low-toxicity herbicide of phenoxy carboxylic acid of Xian Zhengda crop protection company limited of Switzerland exploitation,
Especially effective to pernicious grassy weed, mixed with certain proportion with safener, for cereal crop, to grassy weed such as
Rat-tail amur foxtail, wild oat, rye grass, annual bluegrass, Herba Setariae Viridis etc. have excellent preventive effect.
It is the dispersion in oil insoluble in oily solid pesticide or immiscible liquids pesticide that pesticide oil suspension floats agent, from production
Angle considers, typically requires active compound to be solid at room temperature, and the dissolubility (20 DEG C～40 DEG C) in disperse medium is less than
The pesticide species of 100mg/L.The advantage that pesticide oil suspension floats agent is uniformly can to mix dispersion with oil with arbitrary proportion, easy to use,
It is difficult to pollute environment, can directly or after dilution spray.Preparation for processing can make high dispersive, continuous phase by waterproof pulverization
Suspension, the mean diameter of its particle, typically below 3 microns, substantially increases suspensibility in aqueous medium for the particle, strengthens
Absorptions to medicament for the crops., typically based on cream dosage form, cream is due to environment for existing pair of fluorine clodinafop-propargyl herbicide
Pressure ratio is more serious, is dosage form gradually to be eliminated.
Content of the invention
The present invention proposes a kind of pair of fluorine clodinafop-propargyl oil-suspending agent, and not only suspension stability is high for this suspending agent, meets high sea
Pull out the needs of low temp area, and good drug efficacy.
The technical scheme is that and be achieved in that：
A kind of pair of fluorine clodinafop-propargyl oil-suspending agent, calculates according to percetage by weight, including：
Florasulam 0.5～2%, clodinafop-propargyl 6～12%, wetting agent 2～10%, acrylate-acrylamide-AMPS
Terpolymer 2～8%, thickening agent 0.5～6%, defoamer 0.1～1%, balance of methyl oleate；Described thickening agent is to have
The mixture of machine modified alta-mud, hydrogenated rosin glyceride and hydrogenated rosin pentaerythritol ester composition.
Further, in described thickening agent, the mass percent of each component is：Organic modified bentonite 10～15%, hydrogenation pine
Fragrant glyceride 30～45% and hydrogenated rosin pentaerythritol ester 40～60%.
Further, described wetting agent is fatty alcohol polyglycol ether sulfate, fatty alcohol-polyoxyethylene ether or alkylnaphthalene
Sulfonic formaldehyde condensation compound.
Further, described defoamer is n-octyl alcohol or silicone.
The preparation method of the double fluorine clodinafop-propargyl of the present invention：
1) into mixing kettle add florasulam active compound, clodinafop-propargyl active compound, wetting agent, acrylate-acrylamide-
Terpolymer, defoamer and methyl oleate, under high shear stirring, make material be sufficiently mixed uniformly, obtain mixture
A；
2) and then by mixture A it is heated to 40～60 DEG C, add organic modified bentonite, hydrogenated rosin glyceride and hydrogenation
The mixture of pentalyn composition, is stirred continuously, and after being cooled to room temperature, mixed material is squeezed in sand mill and grinds,
Sand milling 2～3h, you can.
Beneficial effects of the present invention：
1st, the thickening agent of the present invention is organic modified bentonite, hydrogenated rosin glyceride and hydrogenated rosin pentaerythritol ester group
The mixture becoming, organic modified bentonite can not only thickening, help stability and suspending buoyancy, and by organic swelling
The modification of soil enhances its hydrophilic, is conducive to the performance of double fluorine clodinafop-propargyl drug effects.Hydrogenated rosin glyceride and hydrogenated rosin
Pentaerythritol ester is coordinated in organic modified bentonite at 40～60 DEG C, increased the thixotropy of system, strengthens the knot of system
Structure intensity, reduces the condensate oil rate of oils and fatss.
2nd, the dispersant of suspending agent of the present invention adopts acrylate-acrylamide-terpolymer, which increases body
The dispersibility of system, and the intermolecular interaction between this copolymer and thickening agent, reduce and lead to double fluorine sulphurs because viscosity is too high
The probability that careless amine and clodinafop-propargyl active compound easily separate out in low temperature.
3rd, open up good penetrability as object plane when double fluorine clodinafop-propargyl oil-suspending agents of the present invention use, decrease effective one-tenth
Shunting is lost, and has notable synergistic to act on.
