Abstract
The invention provides an herbicide containing methyl oxalate and diflufenzopyr. The herbicide is prepared from, by weight, 6-20% of methyl oxalate, 6-20% of diflufenzopyr, 2-10% of a wetting agent, 2-8% of vinyl acid ester-acrylamide-AMPS ternary copolymer, 0.5-6% of a thickening agent, 0.1-1% of a defoaming agent and the balance methyl oleate. The thickening agent is the mixture prepared from aluminum-magnesium silicate, hydrogenated rosin glycerol ester and hydrogenated rosin pentaerythritol ester. By the adoption of the herbicide, a weed control spectrum is widened, broadleaf weeds and grassy weeds of corn fields can be effectively prevented and killed, and the herbicide usage amount is further decreased.
Description
Technical field
The invention belongs to herbicide technology field is and in particular to a kind of herbicide containing fluthiacet and diflufenzopyr.
Background technology
The corn and soybean field after seedling herbicide that fluthiacet is developed by Japanese combinatorial chemistry company, for tagging
Property after seedling cauline leaf process agent, the effect that can prevent and kill off the broad leaved weeds such as corn field Herba Abutili, Herba chenopodii, smartweed can reach 90%, to Herba Commelinae
Preventive effect Deng broad leaved weed only has 50%, does not prevent and kill off effect to grassy weed.In Semen Maydiss 2～6 leaf phase, weeds 2～5 leaf phase
Apply, can effectively prevent and kill off weeds in field, to the preventive effect of various weeds all 90% about, and good to crop safety, be
More satisfactory mixture formula.Fluthiacet as the kind preventing and kill off broad leaved weed in current corn field herbicide, but its
Only effective to broad leaved weed, invalid to grassy weed, use cost is high, limits its spread and uses.
Diflufenzopyr it be a kind of amino carbamide herbicides, be mainly used in Semen Maydiss postemergence weed control, its broad weed-killing spectrum, Neng Gouyou
Prevent and kill off to effect multiple broad leaved weeds and and undergraduate course weeds.It is reported that, the weeding of diflufenzopyr is general to remove better than presently used corn field
Careless agent.To mesotrione, the weeds such as resistant weeds or Bermuda grass, Herba veronicae have specially good effect for it.But, diflufenzopyr is given birth at home
Produce less, and price is higher, unit area use cost is big to be rather limited with usage amount so as to sell.
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.
Corn field herbicide is limited by crop safety at present, and weed control spectrum is also limited, is used alone a kind of herbicide single dose
The generation of corn field weed can not completely effectively be controlled, furthermore some herbicides due to water solublity is big or the field lasting period too
Long, consumption is excessive or the uneven residual hazard all easily causing to this season crop or succession crop of dispenser.There is presently no and see
To the report containing fluthiacet and diflufenzopyr oil-suspending agent.
Content of the invention
The present invention proposes a kind of herbicide containing fluthiacet and diflufenzopyr, and this herbicide not only expands herbicide
Compose, can effectively prevent and kill off the broad leaved weed of corn field and to grassy weed, also reduce medicament usage amount.
The technical scheme is that and be achieved in that:
A kind of herbicide containing fluthiacet and diflufenzopyr, calculates according to percetage by weight, comprising:
Fluthiacet 6～20%, diflufenzopyr 6～20%, wetting agent 2～10%, ethylene acid esters-acrylamide-
Amps terpolymer 2～8%, thickening agent 0.5～6%, defoamer 0.1～1%, balance of methyl oleate；Described thickening agent
Mixture for aluminium-magnesium silicate, hydrogenated rosin glyceride and hydrogenated rosin pentaerythritol ester composition.
Further, in described thickening agent, the mass percent of each component is: aluminium-magnesium silicate 10～15%, hydrogenated rosin glycerol
Ester 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 containing fluthiacet and the herbicide of diflufenzopyr for the present invention:
1) fluthiacet active compound, diflufenzopyr active compound, wetting agent, ethylene acid esters-acrylamide-are added into mixing kettle
Amps 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 aluminium-magnesium silicate, hydrogenated rosin glyceride and hydrogenated rosin season
The mixture of Doutrate composition, is stirred continuously, and after being cooled to room temperature, mixed material is squeezed in sand mill and grinds, and sand milling 2～
3h, you can.
Beneficial effects of the present invention:
1st, the thickening agent of the present invention be aluminium-magnesium silicate, hydrogenated rosin glyceride and hydrogenated rosin pentaerythritol ester composition mixed
Compound, is conducive to the performance of the effect of herbicides containing fluthiacet and diflufenzopyr.Hydrogenated rosin glyceride and hydrogenated rosin
Pentaerythritol ester is coordinated in aluminium-magnesium silicate at 40～60 DEG C, increased the thixotropy of system, strengthens the structural strength of system,
Reduce the condensate oil rate of oils and fatss.
2nd, the dispersant of suspending agent of the present invention adopts ethylene acid esters-acrylamide-amps terpolymer, which increases body
The dispersibility of system, and the intermolecular interaction between this copolymer and thickening agent, reduce and lead to KIH 9201 because viscosity is too high
The probability that methyl ester and diflufenzopyr active compound easily separate out in low temperature.
3rd, the herbicide containing fluthiacet and diflufenzopyr of the present invention is opening up good penetrability as object plane when using, and subtracts
Lack effective ingredient loss, have notable synergistic to act on.
