Further, the present invention, which is provided, is used to prevent and kill off gramineae weed in wheat paddock for above-mentioned dry suspending agent or broad-leaved is miscellaneous
Grass, especially for preventing and kill off amur foxtail, wild avena sativa, Wang grass, shepherd's purse, Descurainia sophia etc..
Unless otherwise indicated, " % " of the invention refers to weight percent.
It is explained about principle：Although the binary Herbicidal combination of pinoxaden and topramezone has been disclosed in the prior art
Object, but the prior art is not directed to the two weeding single doses and combination being prepared into dry suspending agent, and the present invention is special by selection
Fixed dispersing agent improves the dispersion performance of obtained preparation, while the high-temperature stability of preparation also greatly increases.
Beneficial effect：
Pinoxaden and topramezone dry suspending agent of the invention has good dispersion, suspendability in performance, uses

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit
The fixed present invention.
One, embodiment is prepared
Embodiment 1：30% pinoxaden topramezone dry suspending agent
Embodiment 2：20% pinoxaden topramezone dry suspending agent
Embodiment 3：24% pinoxaden topramezone dry suspending agent
Comparative example 1：In addition to dispersing agent is 20% sodium lignin sulfonate single dose, remaining is the same as embodiment 1.
Comparative example 2：In addition to dispersing agent is 20% APES formaldehyde condensation product single dose, remaining same embodiment
1。
Comparative example 3：Except dispersing agent is 17% sodium lignin sulfonate, 3% APES formaldehyde condensation product
Composite dispersing agent outside, remaining is the same as embodiment 1；
Comparative example 4：Except dispersing agent is that 12% sodium lignin sulfonate, 8% APES formaldehyde condensation product are answered
It closes outside dispersing agent, remaining is the same as embodiment 1；
Comparative example 5：In addition to dispersing agent is 20% dimethyl succinate sulfoacid calcium single dose, remaining is the same as embodiment 1；
Comparative example 6：Except the composite dispersing agent that dispersing agent is 15% sodium lignin sulfonate, 5% dimethyl succinate sulfoacid calcium
Outside, remaining is the same as embodiment 1.
Two, quantitative measurement embodiment
Dry suspending agent of this testing example for being prepared in testing example 1-3 and comparative example 1-6.Stability
Measuring method is：It takes each embodiment dry suspending agent of 15g to be sealed in ampoule bottle, is stored two weeks at 54 ± 2 DEG C, detect it respectively and collapse
Solve speed, dispersibility and suspensibility.
Disintegration rate measuring method is：
100ml standard water is placed in 100ml graduated cylinder, constant temperature in 25 DEG C of water-baths is placed in and uses；
Precise 2.0g dry suspending agent sample, pours into graduated cylinder and is stirred continuously；
Start the watch overturns graduated cylinder with 2s/ speed, while rotating graduated cylinder, the particle of viscous wall is further dispersed, to 40s
When stop overturning.Anyhow by graduated cylinder, observe whether stack shell and bottom have the particle not being disintegrated completely.If having can turn over again on a small quantity
Turn, until 60s stops.In observation stack shell and bottom, it is not disintegrated particle if still having after 60s, is considered as unqualified.
The measuring method of suspensibility uses MT161《The measurement of suspending agent suspensibility》, CIPAC.Handbook F, P.394,
1995.Dispersivity test measuring method uses MT174《The dispersibility of water dispersible granules》, CIPAC.Handbook F, P.394,
1995。
The measurement result for the dry suspending agent being prepared in embodiment 1-3 and comparative example 3-4 is as follows.
Table 1 prepares the performance of dry suspending agent
The result shows that embodiment 1-3 still has lower disintegration time, higher suspensibility and dispersion after overheat storage
Property, heat storage property is excellent.Wherein when in embodiment 1 composite dispersing agent be sodium lignin sulfonate and alkyl phenol polyoxyethylene ether formaldehyde
The portfolio ratio of condensation product is 3:When 1, performance is best.
And comparative example 1-2 is only to contain single dispersant monomer, comparative example 3-4 is although containing having plenty of sodium lignin sulfonate
With the composite dispersing agent of APES formaldehyde condensation product, but its amount ranges is not within the scope of the application and right
Ratio 5 uses other dispersing agent dimethyl succinate sulfoacid calciums, comparative example 6 use sodium lignin sulfonate with it is other
Dispersing agent dimethyl succinate sulfoacid calcium combination, the disintegrating property of these comparative examples itself, dispersibility are compared with suspension
The application is worse, while after heat storage, this three aspects performance of disintegrating property, dispersibility and suspension declines particularly evident, property
It can be poor.
A kind of dry suspending agent containing pinoxaden and topramezone of the invention is carried out by specific example
Description, those skilled in the art can use for reference the content of present invention, the links such as appropriate feed change, process conditions come realize it is corresponding its
Its purpose, correlation change all without departing from the contents of the present invention, and all similar substitutions and modifications are for those skilled in the art
It is it will be apparent that being considered as being included within the scope of the present invention for member.
