The present invention relates to a kind of complex herbicidal composition containing imazethapyr, thifensulfuronmethyl and metribuzin is it is characterised in that the weight ratio of described imazethapyr, thifensulfuronmethyl and metribuzin is：1:2:20‑30:10:1, the compositionss of the present invention can be used for pulse family medicinal plants field, controls unwanted weeds, and potentiation is obvious.
Description
Technical field：
The invention belongs to agriculture herbicide field, it is related to a kind of compounding containing imazethapyr, thifensulfuronmethyl and metribuzin
Herbicidal combinations, for pulse family medicinal plants field, control unwanted weeds.
Technical background：
Imazethapyr (imazethapyr), also known as Imazethapyr, Imazethapyr, CAS registration number is：81385-77-5, structure
Formula is as follows：
Imazethapyr is by the imidazolinone herbicide of american cyanamide (existing BASF) company's exploitation, belongs to acetyl breast
Acid enzyme (ALS) or acetic acid hydroxy acid synzyme (AHAs) inhibitor, it passes through root, stem, leaf absorb, can be in xylem and tough
Skin zone conducts, and accumulates in plant meristem, the activity of suppression acetic acid hydroxy acid synzyme, impact L-Valine, leucine, different bright
The biosynthesiss of propylhomoserin, destroy protein synthesis, make plant growing suppressed and dead.Can be used for preventing and kill off annual and for many years
Raw grassy weed and broad leaved weed, such as barnyard grass, Herba Setariae Viridis, Herba Digitariae, wild oat, Herba Commelinae, Herba Portulacae etc..
Thifensulfuronmethyl (thifensulfuron-methyl), CAS registration number is：79277-67-1, structural formula is as follows：
Thifensulfuronmethyl is the sulfonylurea herbicide of E.I.Du Pont Company's exploitation, is a kind of inner sucting conduction type after seedling selective herbicidal
Agent, belongs to acetolactate synthestase (ALS) inhibitor.It is mainly used in preventing and kill off annual and perennial broadleaf weed such as Dens Equi
Herba Amaranthi tricoloriss, Herba monochoriae vaginaliss, Herba Galii Teneri, Herba veronicae, Caulis et Folium Brassicae junceae, wild oat, Herba Setariae Viridis etc..By leaves of plants, root absorption after dispenser, and pass rapidly
Lead, the biosynthesiss of L-Valine, leucine and isoleucine can be suppressed in sensitive crop body to stop cell division, make sensitivity
Plant stops growing and dead.
Metribuzin (metribuzin), CAS registration number is：21087-64-9, structural formula is as follows：
Metribuzin is the Triazinone herbicide developed by E.I.Du Pont Company, can be used for preventing and kill off annual broad leaved weed and
Part grassy weed, such as to Herba Portulacae, Herba Amaranthi tricoloriss grass, Herba chenopodii, Herba stellariae mediae and other effects is fabulous, can be also used for preventing and kill off Herba Setariae Viridis, Herba Digitariae,
Barnyard grass, wild oat etc., bad to perennial weeds effect.The mechanism of action be absorbed by weeds root system after with transpiration current to upload
Lead, absorbed by stem and leaf and make limited conduction in vivo.Play removing activity, dispenser by suppressing the photosynthesis of sensitive plant
Each susceptible weeds are sprouted and are emerged unaffected afterwards, and rear blade of emerging moves back green, and last nutrition is exhausted and lethal.
Due to life-time service herbicide, annual times for spraying and dosage are all being gradually increased, and herbicide selects to weeds
Property constantly rises, and drug effect constantly declines.So that common weed sensitivity significantly reduces, crop smothering is asked for pesticide use single for a long time
Topic is increasingly serious.Rationally compounding of different herbicides not only can improve drug effect, expands herbicidal spectrum, can also delay the anti-of weeds
Property, reduce use cost and can also mitigate the pollution to environment simultaneously.There is presently no imazethapyr, thifensulfuronmethyl and piperazine grass
The report of the complex weedicide of ketone.
Content of the invention：
It is an object of the invention to provide the low herbicidal composition of drug cost, the grass family to medicinal plants field and wealthy
Leaf weeds all have preferable prevention effect.The technical solution adopted in the present invention is：
A kind of complex herbicidal composition containing imazethapyr, thifensulfuronmethyl and metribuzin is it is characterised in that described imidazoles
The weight ratio of second nicotinic acid, thifensulfuronmethyl and metribuzin is：1:2:20-30:10:1, preferably 3:5:10-20:7:13, further
It is preferably 5:6:14-10:7:20.Described imazethapyr, thifensulfuronmethyl and metribuzin content in the formulation is 10-85%,
Preferably 30-75%.The conven-tional adjuvants allowing on Herbicidal combinations and pesticidal preparations are configured to any one agent allow on pesticide
Type.
The Herbicidal combinations of the present invention can be used for pulse family medicinal plants (the such as Radix Astragali, Radix Glycyrrhizae, Radix Sophorae Flavescentiss, Radix Puerariae, Radix Sophorae Tonkinensiss
Deng) field, control unwanted weeds.
The preparation agent that herbicidal composition of the present invention can be prepared according to the method well known to those skilled in the art of the present technique
Type, includes, but are not limited to cream, water dispersible granules, wettable powder, oil-suspending agent, microemulsion, powder, ultra low volume liquids
Deng.When preparing above-mentioned dosage form, such as wetting agent, dispersant, thickening can be added in effective ingredient according to the actual needs
Agent, the conven-tional adjuvants that the pesticidal preparations such as antifreezing agent allow.Such as dispersant can be polycarboxylate, lignosulfonates, alkane
One or more in base naphthalene sulfonate etc.；Wetting agent such as sodium lauryl sulphate, dodecylbenzene sodium sulfonate, alkyl polyoxyethylene

In Oleum Gossypii semen, Semen Ricini oil, Oleum Terebinthinae, enriching vegetable oil, Oleum helianthi, mineral oil, methyl oleate, one or more etc. often
Rule auxiliary agent.
Specific embodiment
With reference to embodiment to further instruction of the present invention, the percentage ratio in embodiment is weight ratio, but this
Bright it is not limited thereto.
1st, toxicity measures
For further appreciating that the synergy to weeds for the mixture of the application, the present inventor is to imazethapyr, thiophene sulphur
Grand and metribuzin mixture has carried out cauline leaf process synergy toxicity and has measured.
Test material：Herba Galii Teneri, wild oat.
Test method：
Weigh a certain amount of weeding effective ingredient active compound, after fully dissolving, be configured to single dose mother solution respectively, according to mixture mesh
Setting series proportioning, each proportioning arrange 5～7 Concentraton gradient.Representative sensitivity is selected according to single dose herbicidal spectrum
Weed seed, cultivates standby to 3 leaf 1 heart.After the weeds cauline leaf process that will select to number, it is placed on incubated at room temperature in illumination box
20 days, calculate prevention effect (fresh weight preventive effect or strain preventive effect), then calculate ED with method of least square50(95% confidence limit), then use
The abundant method of Sun Yun calculates co-toxicity coefficient (CTC).Co-toxicity coefficient (CTC) >=120 shows as potentiation；Co-toxicity coefficient (CTC)≤80
Show as antagonism；80 ＜ co-toxicity coefficient (CTC) ＜ 120 show as summation action.Test result is shown in Table 1 and 2.
Table 1 different ratio imazethapyr, the thifensulfuronmethyl and metribuzin synergy measurement result to Herba Galii Teneri
Table 2, different ratio imazethapyr, the thifensulfuronmethyl and metribuzin synergy measurement result to wild oat
The compositionss of imazethapyr, thifensulfuronmethyl and metribuzin be can be seen that 1 by the measurement result of table 1 and 2:2:
20-30:10:Between 1 ratio, there is obvious potentiation.10:7:, co-toxicity coefficient best to the synergistic effect of Herba Galii Teneri when 6
For 152.84；3:5:The most obvious to the potentiation of wild oat when 10, co-toxicity coefficient has reached 143.38.
