Description
Technical field
The invention belongs to field of pesticide preparation, and in particular to a kind of florasulam and pinoxaden compounded cream and its system
Preparation Method.
Background technique
Application of chemical herbicide during Wheat Production improves wheat yield side for controlling wheat weeds in field
Face plays obvious action, but the long-time service bring of chemical herbicide gets worse resistance problem, resistant weed
Occur becoming persistent ailment during wheat prevention and treatment.
Florasulam is inner-adsorption conduction-type herbicide, can be absorbed by plant leaf surface and root system, accumulate in separate living tissue
And keep plant gradually dead.Typical poisoning symptom are as follows: leaf chlorosis, albefaction or purpling, shortened internodes, terminal bud death, finally
Complete stool is dead.The herbicide has bioactivity height, the advantages of broad weed-killing spectrum, due to its action target ALS enzyme be not related to people and
Animal, therefore this kind of herbicide has very high safety to humans and animals.
Pinoxaden is novel neophyl pyrazoles herbicide, it mainly passes through the synthesis for preventing fatty acid, to make
The mitogenetic effect of plant disappears, and causes plant dead, is not easy photodissociation, is easy degradation, is adsorbed in soil, it is difficult to leaching and wave
Hair.Many can be removed and be difficult to the annual gramineous weed killed, especially there is stronger effect to wild wheat straw, herba setariae viridis grass
Fruit does not influence the normal growth and development of crop.
Currently, florasulam and pinoxaden compound emulsion performance are bad, there is precipitating, in order to solve this problem, hereby
It is proposed the present invention.
Summary of the invention
It is an object of that present invention to provide a kind of florasulams and pinoxaden complex weedicide missible oil, are used for wheat paddock one
The prevention and treatment of year raw weeds, with synergistic effect.
The present invention is realized by following technological means: a kind of florasulam and pinoxaden complex weedicide cream
Oil contains the following parts by weight:

Further, the compounded cream contains the following parts by weight:
0.2~2 part of florasulam
3~15 parts of pinoxaden
15~40 parts of polar solvent
24~64.3 parts of nonpolar solvent
9~13 parts of emulsifier
0.5~1.5 part of stabilizer.
Preferably, the compounded cream contains the following parts by weight:
0.5~1 part of florasulam
8~10 parts of pinoxaden
20~32 parts of polar solvent
59.5~62.5 parts of nonpolar solvent
10~12 parts of emulsifier
1~1.2 part of stabilizer.
Further, the polar solvent is selected from methanol, ethyl alcohol, n,N-Dimethylformamide (DMF), dimethyl sulfoxide
(DMSO), at least one of acetophenone, isophorone, cyclohexanone, methyl pyrrolidone.Further, the nonpolarity is molten
Agent is selected from least one of toluene, dimethylbenzene, aromatic solvent naphtha, methyl oleate, turpentine oil.
Further, the emulsifier is selected from styrylphenol polyoxyethylene ether agriculture breast (agriculture breast 600#), styrene
Base phenol polyoxyethylene phosphonate, APES formaldehyde condensation product agriculture breast (Nongru-700 #), phenethyl phenyl are poly-
One polyethenoxy ether agriculture breast (agriculture breast 1600#) of ethylene oxide, styrylphenol formaldehyde resin PULLRONIC F68 block type
Polyethers (agriculture breast 33#), castor oil polyoxyethylene ether, aliphatic APEO, EO-PO block polyether, dodecyl benzene sulfonic acid
At least one of calcium (agriculture breast 500#).
Further, the stabilizer is selected from butylated hydroxy anisole BHA, and 2,6- toluene di-tert-butyl phenol BHT are not eaten
At least one of sub- propyl propionate PG.
Further, dosage form stirring solvent is added in florasulam all to dissolve, pinoxaden is added and nonpolarity is molten
Then agent, stirring and dissolving are added emulsifier for mixing and are uniformly mixed, finished product is obtained by filtration.
Another object of the present invention is that providing a kind of florasulam and pinoxaden complex weedicide missible oil
Preparation method, comprising the following steps: first weigh each component according to parts by weight, then polar solvent stirring be added in florasulam
Middle all dissolutions, are added pinoxaden and nonpolar solvent, then stirring and dissolving adds emulsifier, stabilizer, are stirred
