Description
Technical field
This disclosure relates to technical field of pesticide, and in particular, to a kind of herbicidal composition and its application.
Background technology
Wheat is the staple food crop of China's plantation, including wheat (winter wheat and spring wheat), barley (winter barley and spring
Barley), rye and wheat (highland barley).Weeds in field and wheat strive water, strive fertilizer, strive sunlight, be influence wheat yield it is main because
One of element is such as not added with to prevent, can cause a large amount of underproduction of wheat.The weeds of main harm wheatland have：Wild oat, rye grass,
Green bristlegrass, amur foxtail, hard grass, Wang grass, caput grass, Phalaris grass, clearvers, Descurainia sophia, shepherd's purse, chickweed etc..And seedling stage harm is maximum,
The dwarfing of wheat plant, bar spire Huang etc. can be caused to seriously affect wheat yield, can underproduction amplitude up to 30% or so.
Currently used for wheatland seedling rear defence except weeds in field major herbicides kind there are safeties by environmental condition (especially
It is temperature and humidity condition) it is affected, drift strong disadvantage；And the long-term single use of herbicide leads to the anti-medicine of a variety of weeds in field
Property rapid development, if increase usage amount wheat seeding poisoning risk can be caused big；Secondly existing herbicide use cost is high, and weeds are easily multiple
Hair.With the increase of cornfield herbicidal service life, the Weed species and quality that wheatland field is difficult to prevent and kill off is increasing.Cause
This, there is an urgent need to develop a kind of efficient, low toxicity, low-residual, safety novel cornfield herbicidal.
Invention content
Purpose of this disclosure is to provide a kind of new herbicides, which can effectively prevent wheatland weeds in field, carry
High wheat yield.
To achieve the goals above, the disclosure provides a kind of herbicidal composition, and the herbicidal composition is containing active
Ingredient, which is characterized in that the active constituent includes pinoxaden, florasulam and mefenpyrdiethyl；Pinoxaden, double fluorine
The weight ratio of sulphur grass amine and mefenpyrdiethyl is 1：(0.01-90)：(0.01-90).
On the other hand, the present invention also provides herbicidal compositions as described above in preventing crops weeds in field
Using.
Through the above technical solutions, the present invention composition pesticide in active constituent pinoxaden, florasulam and
Mefenpyrdiethyl is proportionally applied in combination, and can effectively prevent the weeds in field of multiple kinds of crops.
Relative to being used alone pinoxaden, florasulam or mefenpyrdiethyl, and with use pinoxaden, double fluorine
Arbitrary the two in sulphur grass amine and mefenpyrdiethyl is used in compounding, and has more significant control effect, pinoxaden, double fluorine sulphurs grass
The use ratio of amine and mefenpyrdiethyl has synergistic effect in a wider scope, it is possible to reduce dosage reduces cost, subtracts
Light pollution of the pesticide residue to environment.Pinoxaden, florasulam and pyrazoles in the herbicidal composition of the present invention simultaneously
Cloquitocet_mexyl is applied in combination according to special ratios, can be carried out at the same time prevention to a variety of weeds in field, relative to oligomict oxazoline grass
Ester, florasulam can obtain the effect of notable synergistic, and dosage is low, not only delay the development of weed resistance but also save
Cost.The herbicidal composition of the present invention is suitable for the prevention of wheatland weeds in field, and safety is good, is risen to the protection of ecological environment
Positive effect is arrived.
Other feature and advantage of the disclosure will be described in detail in subsequent specific embodiment part.
Specific implementation mode

Testing example 1
The herbicidal composition of testing example 1-14 and comparative example 1-8 imitate the prevention of weeds in wheat planting field
Fruit, specific steps include：When wheat seeding is in the 3-5 leaf phases, herbicide sprays are carried out, embodiment 1-11 and comparative example 1-8's removes
The amount of application of careless agent composition is 100g/ mus, and the amount of application of the herbicidal composition of embodiment 12-13 is 25g/ mus, is implemented
The amount of application of the herbicidal composition of example 14 is 50g/ mus.The area for testing the growing area of each herbicidal composition is 5 mu,
Using when to be diluted with water to spray amount per acre be 30L, and herbicidal composition is substituted as space management using water.Spray herbicide
After 40 days, counting is identified to the weeds of growing area, by formula (A) calculate strain preventive effect, and to the wheat yield of growing area into
Row statistics, the results are shown in Table 1.
Table 1
Embodiment 1-14 in table 1 compared with the data of comparative example 1-8 it can be seen from pinoxaden in the present invention,
Florasulam and mefenpyrdiethyl ternary recompounded composite are relative to oligomict pinoxaden, florasulam and pyrazoles solution
The two of careless ester or pinoxaden and florasulam, pinoxaden and mefenpyrdiethyl, florasulam and mefenpyrdiethyl
The herbicidal composition of member compounding or other ingredients, control effect is good, has synergistic effect, and safe to wheat.It will
Embodiment 1-11 is compared as can be seen that the weight ratio of pinoxaden, florasulam and mefenpyrdiethyl is 1：(0.05-
30)：(0.1-50) is especially 1 in the weight ratio of pinoxaden, florasulam and mefenpyrdiethyl：(0.1-1)：(0.5-
5) it can further improve control effect when, and herbicide controlling spectrum can be expanded, delaying drug resistance generates, and reduces dosage and greatly carries
Safety and raising crop yield of the height to crop.In addition, can be seen that the herbicidal composition of the present invention from embodiment 1-14
When preferred dosage form is oil-suspending agent, better control effect can be obtained relative to other dosage forms.
