The problem of the preventive effects such as dayflower, youngia japonica, purslane, affine cudweed, acalypha copperleaf, sowthistle difference.
Thus Ben Fa the technical solution adopted is that: the oily suspension herbicide of a kind of glyphosate and dicamba combination contains grass
Sweet phosphine raw medicine 1%~30%, dicamba raw medicine 0.5%~10%, 1% ~ 5% rheological agent, surfactant 1%~30%, oily matter 1%
~50%.
Preferably, the oily suspension herbicide of a kind of glyphosate and dicamba combination of the present invention, calculates in proportion,
Optimal proportion 1:3 ~ 1:6 of dicamba raw medicine and the two of glyphosate technicals.
Preferably, the surfactant are as follows: aerosol-OT salt (fast penetrant T), fatty alcohol polyoxy
Vinethene (AEO), calcium dodecyl benzene sulfonate, ethylene oxide propylene oxide block base ether, alkyl phenol polyoxyethylene ether, octyl phenol
One or more of polyoxyethylene ether, sorbitol polyoxyethylene ether, castor oil polyoxyethylene ether (BY).
Preferably, the oily matter is selected from soybean oil, rapeseed oil, palm oil, methyl esterification soybean oil, esterification vegetable seed
Oil, methyl oleate, esterification palm oil, castor oil, cottonseed oil, isopropyl myristate, isopropyl laurate, pine nut base plant
One or more of oil.
Preferably, the rheological agent substance is selected from inorganic silicic acid magnalium, organic silicic acid magnalium, and organobentonite is concave-convex
Stick soil, carboxymethyl cellulose, hydroxypropyl cellulose, fume colloidal silica, one or more of sedimentation white carbon black.
The present invention provides the oil-suspending agent agent preparation method of a kind of herbicide glyphosate and dicamba component, includes following step
It is rapid:
Step (1), by glyphosate technicals described in 1%~30% and 0.5% ~ 10% dicamba raw medicine, 1% ~ 30% surface-active
Agent and 1% ~ 5% rheological agent dissolution are dispersed in 1% ~ 50% oily matter, stirred at low speed to be formed particle diameter distribution 100 ~
The suspension of 2000 microns.
Step (1) obtained suspension is passed through high speed shear by step (2), and colloid mill rough lapping obtains particle diameter
The rough segmentation for being distributed in 10 ~ 100 microns dissipates oil-suspending agent liquid, then by this thick suspension by the way of horizontal wet process sand milling
It is sanded until partial size reaches 1 ~ 3 micron repeatedly, obtains final uniform sticky glyphosate dicamba oil-suspending agent product.
The beneficial effects of the present invention are: glyphosate is one of maximum herbicide of current usage amount.Due to glyphosate single dose
Long-term, a large amount of uses, cause resistance weed to enhance year by year, especially part broadleaf weeds, which produces glyphosate, compares
Serious resistance, control efficiency are declining year by year；Glyphosate is undesirable etc. in 15 DEG C of using effects below of low temperature, leads to its city
The field service life is affected to some extent.It is one big to become current glyphosate industry for the mixture of herbicides of glyphosate and different role mechanism
Developing direction.Dicamba belongs to fragrance and rests in peace acid herbicides, better than glyphosate to the control efficiency of broadleaf weeds, can be effective
The broadleaf weeds prevented and kill off purslane, affine cudweed, acalypha copperleaf, sowthistle etc. and generate serious resistance to glyphosate, the two is carried out
After compounding, glyphosate can be greatly improved to the control efficiency of broadleaf weeds, reduce dosage and times for spraying, improve anti-
Except effect, drug cost is saved.
The surfactant contained in pharmaceutical formulation has very strong wetting permeability, can quickly dissolve weeds leaf
The wax coat of piece, makes that drug is easier to penetrate blade surface and then osmotic absorption enters in weeds body and plays a role.Weeds are low
Under conditions of warm condition is dry, it for the protection mechanism of itself, will increase the wax coat thickness of grass cutting blade, reduce Stoma of Leaves
Opening degree and quantity, reduce with extraneous water-vapor exchange frequency, to reduce the transpiration of itself moisture and be lost, and this guarantor
Protection mechanism also hinders grass cutting blade to the uptake of herbicide simultaneously, causes under the usage amount of same dose, northern low temperature
Regional effect will be much worse than southern high-temperature area.After the surfactants such as wetting and penetrating agent are added, these surfactants can be with
The hydrophobicity wax coat of grass cutting blade is quickly dissolved, the fractional open again of grass cutting blade stomata is promoted, accelerates steam and hands over
The frequency changed, so as to promote glufosinate-ammonium and fluoroglycofen-ethyl in the infiltration and absorption of grass cutting blade.
The processing dosage form of preparation is oil-suspending agent, using botanical solvent oil as diluent, with common glyphosate water
Dosage form using mineral sources solvent naphtha as diluent of agent or dicamba aqueous solution or part is compared, and oil belongs to nonpolar solvent, and miscellaneous
The affinity on careless surface is much more much bigger than the water of polar solvent, compared with normal aromatic hydrocarbon mineral sources solvent oil component, because planting
Material resource solvent naphtha derives from plant itself, and the affinity of the plants such as botanical solvent oil and weeds is higher than mineral sources solvent naphtha,
It is easier to be absorbed by ruderal plant, and the boiling point of botanical solvent oil is higher than the boiling point of normal aromatic hydrocarbon mineral sources solvent naphtha,
Evaporation rate in air is slower than mineral sources solvent naphtha, and weeds surface can be made to keep moisture state for a long time, extends weeds to removing
The soak time of careless agent glyphosate and dicamba drug increases uptake, to guarantee that weeds can be absorbed into enough lethal doses
Herbicide effective component overcomes currently on the market generally because low temperature humidity is low, and being air-dried causes medicine liquid spray to grass cutting blade
Quickly volatilization, active ingredients of the original drug are precipitated at solid crystal quickly after upper, and weeds is caused significantly to subtract the absorption of effective component
Cause herbicidal effect very poor less, weeds after death the case where bringing back to life again.Glyphosate and dicamba effective component can be made to exist
Be sprayed onto behind weeds blade face can the long period holding liquid, prolong plus weeds absorb time of herbicide, to guarantee weeds energy
It is enough absorbed into the herbicide of enough lethal doses, overcomes product on the existing market very poor row of using effect under cryogenic
Industry problem.
