Description
Technical field
The present invention relates to field of pesticide chemistry, and in particular to a kind of thickener composition for glufosinate-ammonium and dimethyl tetrachloride and
It is prepared and application.
Background technique
Glufosinate-ammonium is that the organic phosphates wide spectrum of former Ai Gefu company of Germany exploitation goes out natural disposition cauline leaf process herbicide, effect target
It is designated as glutamine synthelase, after spraying 3~5d of glufosinate-ammonium, the rate of the fixed carbon dioxide of plant declines rapidly, plant leaf blade
There is withered and yellow and downright bad symptom.The features such as active height of glufosinate-ammonium, good absorbing, broad weed-killing spectrum, low toxicity, good environment compatibility,
It is the steriland herbicide of the another function admirable after glyphosate.
The weeds that herbicide mixture prevents and kill off the crop fields play the effect of highly significant really, with asking for genetically modified crops
Generation, some non-selective inorganic agents are widely used to crop, but reuse same herbicide and will lead to weed community
Change, and some weeds can be made to generate resistance to selective herbicide, how avoid or postpone Weed Resistance just mentioning day
Come in journey.Herbicide mixture and mixture have the advantages that single dose is incomparable in all various aspects, and effect mainly expands herbicide
It composes, extends the optimum period for applying fertilizer, reduce residual activity, reduce phytotoxicity, improve herbicidal effect, it is miscellaneous to avoid, delay and control generation resistance
Grass.Herbicide mixture important role in terms of the usage amount for reducing herbicide.New herbicide kind (when being applied alone) is in property
Can on to be more than mixed be very difficult to.The mixed defect that can make up herbicide degrass spectrum, reduces dosage and cost, reduces pollution
Or the chance of toxicity, some new herbicides are only mixed just to have use.
After glufosinate-ammonium and dimethyl tetrachloride compounding, increasing action target site expands degrass spectrum, extends the optimum period for applying fertilizer, reduces
Residual activity reduces phytotoxicity, improves herbicidal effect, avoids, delays and control generation resistant weed.But existing thickener exists
Formulation viscosity can not be increased in preparation glufosinate-ammonium and dimethyl tetrachloride aqua, stability is poor, is easy to appear layering, to influence weeding
Effect.
Summary of the invention
In view of the deficiency of the prior art, the present invention provides a kind of stable and be used for certain viscosity
The thickener composition of glufosinate-ammonium and dimethyl tetrachloride, the composition are combined dedicated for the aqua of glufosinate-ammonium and dimethyl tetrachloride with this
Object substitutes the conventional auxiliary agent without thickening effect, can improve adherency of the medical fluid on blade face and reduce that rain drop erosion, blowing causes Plant Leaf
Medicament caused by piece is mutually collided and rubbed is lost, and improves using effect.
It is a further object of the present invention to provide the preparation method of the thickener composition, this method is simple, efficient.
It is removing for glufosinate-ammonium and dimethyl tetrachloride that another object of the present invention, which is to provide the thickener composition in effective component,
Application in careless agent, the glufosinate-ammonium containing the thickener composition and dimethyl tetrachloride aqua, viscosity significantly improve, and can improve medical fluid
Adherency on blade face reduces rain drop erosion, blow cause plant leaf mutually collide and rub caused by medicament loss, raising makes
Use effect.
To solve above-mentioned the deficiencies in the prior art, technical scheme is as follows:
A kind of thickener composition for glufosinate-ammonium and dimethyl tetrachloride, the composition is according to mass percentage by such as the following group
Be grouped as: ammonium pyrrolidine dithiocarbamate 1%-3%, surfactant 15%-55%, salt 1%-5%, surplus are
Water；The surfactant be one or both of (A), (B),
(A) first kind surfactant, structural formula are as follows:
Wherein n=6-20 and be integer；
(B) the second class surfactant, structural formula are as follows:
Wherein R1For C12-C22 is linear or the saturation of branching or
Aliphatic unsaturated hydrocarbon, R2For C10-C18 is linear or the saturation or aliphatic unsaturated hydrocarbon of branching, a=4-18 and be integer.
In preferred technical solution, the cation in the salt is 1 valence or divalent.
In preferred technical solution, the salt is sodium chloride, ammonium chloride or ammonium sulfate.
The present invention also provides the preparation method of the thickener composition, include the following steps: the pyrrolidines two in formula ratio
Add water in thiocarbamic acid ammonium and surfactant, be warming up to 40 DEG C -50 DEG C, stirring to solid is dissolved, and formula ratio is added
Salt stirs to uniform system, obtains thickener blend composition.
The present invention also provides the thickener composition answering in the herbicide that effective component is glufosinate-ammonium and dimethyl tetrachloride
With.
In the present invention, the mass percentage of glufosinate-ammonium is 18-25%, the quality hundred of dimethyl tetrachloride in the herbicide
Dividing content is 0.5-3%.
In the present invention, the mass percentage of thickener composition is 5-35% in the herbicide.
In preferred technical solution, the mass percentage of thickener composition is 10-20% in the herbicide.
In preferred technical solution, the mass percentage of thickener composition is 15-18% in the herbicide.
Thickener composition of the present invention can dramatically increase the viscous of the herbicide that effective component is glufosinate-ammonium and dimethyl tetrachloride
Degree has the raising of at least 85cp.s viscosity, significantly improves medical fluid in the adherency on target blade face, reduces rain drop erosion, blows
Medicament caused by causing plant leaf mutually to collide and rub is lost, and improves using effect, significantly reduces glufosinate-ammonium and diformazan four
The usage amount of chlorine.
