Description
Technical field
The invention belongs to herbicide technology fields, and in particular to a kind of Herbicidal combinations containing diflufenican and its answer
With.
Background technique
In agricultural production process, serious, the target crops such as damage to crops, forest life occurs for unwanted plant (weeds)
It is long, and influence undesirable vegetation plot (such as bare place, railway, highway, forest fire protection road, industrial sites, threshing ground) just
It is often used.Herbicide is to prevent and kill off the method the most economic, quick and effective for not needing plant.
Single herbicide use is easy to produce drug resistance or prevention spectrum is limited, not can be well solved production in practice not
Need the harm of plant.Mixture herbicide delays the advantages such as herbicide resistance, in life with that can expand prevention spectrum, enhancing preventive effect
Producing becomes most popular application form in practice.Herbicide especially with synergy, between each active principle of herbicide
Interaction makes combination aging fruit better than the theoretical summation of exclusive use effect, thus can play half function of thing in actual use
Effect again, is more welcome by user.
Summary of the invention
The present invention proposes that a kind of Herbicidal combinations containing diflufenican, the Herbicidal combinations pass through three kinds of active constituents
Compounding, can prevent and treat wheat paddock annual grassy weeds comprehensively.
The technical scheme of the present invention is realized as follows:
A kind of Herbicidal combinations containing diflufenican, including active components A, active constituent B and active constituent C, it is described
Active components A is phenylpyrrazolin class, and the active constituent B is ureas, and the active constituent C is diflufenican.
Preferably, the phenylpyrrazolin class is pinoxaden, and the ureas is isoproturon.
Preferably, the pinoxaden, the mass ratio of the isoproturon and the diflufenican be 5~25:10~
70:1~9.
Preferably, the mass ratio of the pinoxaden, the isoproturon and the diflufenican is 10-20:15-
50:2-5。
Preferably, the specific preparation of the Herbicidal combinations containing diflufenican is missible oil, suspending agent, microemulsion, water
Emulsion, dispersible oil-suspending agent, wettable powder or water dispersible granules.
Application of the above-mentioned Herbicidal combinations containing diflufenican in prevention and treatment injurious weed.It is miscellaneous to be preferred for wheat paddock
Grass.
Herbicidal combinations of the present invention containing diflufenican can be by that can make active constituent with Pesticide formulation
Auxiliary agent mixing, conventional preparation is prepared as with known method, as missible oil, wettable powder, water dispersible granules, suspending agent,
Aqueous emulsion, microemulsion, granule, dispersible oil-suspending agent, microcapsule suspending agent, solvable pulvis, soluble granule etc..It is general in preparation
Active constituent containing 0.1~95% weight, the preferably active constituent of 0.5~90% weight.
The auxiliary agent that can be used in Pesticide formulation includes but is not limited to: water, solvent, filler, various surfactants
(emulsifier, dispersing agent, wetting agent etc.), adhesive, colorant, antifreezing agent, thickener, suspending agent, disintegrating agent, disappear at film forming agent
Infusion, bleeding agent, synergist, stabilizer, wall capsule material, pH adjusting agent, preservative etc..Also, suitably, in order to improve to spy
Ordered goods tolerance can be properly added safener；Or sometimes for crop growth is promoted, it can add in mixed composition
Add conventional agriculture fertilizer, medicament-fertilizer mixture is made.These auxiliary agents are all ingredients commonly used or allowed to use in pesticidal preparations, have no spy
It does not limit, one or more auxiliary agent composition may be selected, specific ingredient and dosage pass through according to recipe requirements simply to be tested
It determines.
Beneficial effects of the present invention:
A kind of chemical weeding higher cost is applied alone, effect is poor, and it is especially poor to malignant weed preventive effect, and it is easy to produce anti-medicine
Property.Three compounds disadvantage complementation, expands degrass spectrum and reduces costs.Pinoxaden, isoproturon and diflufenican are multiple
With with significant synergistic effect, it can effectively lower active constituent dosage, mitigate environmental pollution.

Application effect example 1
Material to be tested: Seed storage is collected in barnyard grass, this laboratory field
Test method: barnyard grass seed point is sowed in the iron basin of the sectional area 0.25m2 equipped with soil, is cultivated in greenhouse, 2
Leaf phase or so thinning, the consistent barnyard grasses of surplus 15 growths of every basin grow to the 3-4 leaf phase to it and are handled.With 0.5% tween-
80 aqueous solutions configure medical fluid, spray medical fluid with POTTER precision laboratory spray tower, ground moistening is kept after medicine, and set clear water sky
White control.Every processing is repeated 4 times, and measures the inhibition percentage of 14 days barnyard grass aerial part fresh weights after medicine, is evaluated according to Colby method
Herbicide associated form.Evaluation criterion: as E ﹣ E0 > 10%, it is expressed as synergistic effect；As ﹣ 10%≤E ﹣ E0≤10%,
Show as summation action；As E ﹣ E0 < ﹣ 10%, antagonism is shown as.
1 pinoxaden of table, isoproturon and diflufenican ternary built measure the synergy of barnyard grass
As shown in Table 1, pinoxaden, isoproturon and diflufenican ternary built show significant synergy work to barnyard grass
With three, which is used in compounding, can effectively reduce active constituent dosage, slow down the generation of herbicide resistance, reduce environmental pollution.
Application effect example 2
Subjects: wheat paddock grass family and broadleaf weeds: barnyard grass, amur foxtail, Wang grass, clearvers, herba stellariae mediae etc..
Test medicine: embodiment 1-4 medicament and comparison medicament
Test method: weeds are in the 2-3 leaf phase, carry out cauline leaf 1 time by spraying using backpack sprayer, fresh weight after investigation 14 days
Preventive effect, and the activity of weeding of more various medicaments.Preventive effect (%)=[(clear water control group weeds fresh weight-processing group weeds fresh weight)/
Clear water group weeds fresh weight] * 100%.
2 pinoxaden of table, isoproturon and diflufenican ternary built are to weeds of wheat field efficacy
As seen from the above table, compared with single dose, pinoxaden, isoproturon and the application of diflufenican ternary built can expand
Herbicidal spectrum, and its control efficiency to weeds can be significantly improved, it has significant synergies, can effectively lower pesticide
Administration dosage reduces environmental pollution；And field observation is to wheat crop safety.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
