Abstract
The present invention provides a kind of mixed herbicide containing proxazuron-methyl, penoxsuam and bentazone and its application；Active constituent is made of proxazuron-methyl, penoxsuam and bentazone, and the weight ratio of the proxazuron-methyl, penoxsuam and bentazone is 1-40:1-20:1-100；It can be used for broadleaf weeds, gramineae weed and the prevention and treatment of nutgrass flatsedge.
Description
Technical field
The invention belongs to pesticide fields, and in particular to a kind of mixing containing proxazuron-methyl, penoxsuam and bentazone
Herbicide and its application.
Background technique
Proxazuron-methyl is pyrimidine radicals sulfonylurea herbicide developed by Japan Sumitomo Chemical, although with other sulfonylureas
The mechanism of action of class herbicide is identical, is acetolactate synthestase (ALS) inhibitor, but it fights the miscellaneous of sulfonylurea herbicide
Grass has good preventive effect, is mainly used for paddy field and prevents and kill off grass family and broadleaf weeds.The product dosage is low, to certain known sulphonyl
The weeds that carbamide herbicides generate resistance have good preventive effect.Penoxsuam category triazolopyrimidine sulfonamides herbicide, can
Barnyard grass, semen euphorbiae and annual sedge weed effectively are prevented and kill off, and effective to numerous broadleaf weeds, such as the raw different stamen flower in natural pond, carp
Intestines, sesbania, ring flower, Monochoria vaginalis etc..Bentazone is the selective herbicide after seedling of contact killing type, can be used for rice, wheat, big
The various crops Tanaka such as beans, corn, pea prevents and kill off broadleaf weeds and sedge weed.
Compounding between herbicide not only can solve the problem that pesticide single dose toxicity is big, effect is poor, but also less investment, R&D cycle
It is short, and it is used interchangeably the generation for capableing of retarding action object drug resistance between different pesticides, it is imitated with ideal use
Fruit, therefore the compounding of pesticide is current research focus in the field of pesticide between different role mechanism.Patent document
(CN103271065A) Herbicidal combinations that effective component is proxazuron-methyl and bentazone are disclosed；Patent document
(CN106172457A) Herbicidal combinations of proxazuron-methyl and penoxsuam are disclosed；Patent document (CN105519549A)
Disclose the Herbicidal combinations of penoxsuam and bentazone.It proxazuron-methyl, penoxsuam and does not go out in the prior art
Careless pine compounding ternary weeding composition.
Summary of the invention
The purpose of the present invention is to provide a kind of component is reasonable, drug cost is low, is not likely to produce the herbicide group of drug resistance
Close object, to paddy field, wheatland grass family, broadleaf weeds, nutgrass flatsedge have preferable control efficiency, to slow down Weed Resistance, reduce
Drug dosage etc. has positive effect.
The present invention provides following technical scheme
A kind of mixed herbicide containing proxazuron-methyl, penoxsuam and bentazone, active constituent by proxazuron-methyl,
Penoxsuam and bentazone composition, the weight ratio of the proxazuron-methyl, penoxsuam and bentazone are 1-40:1-
20:1-100。
The weight ratio of mixed herbicide of the present invention, the proxazuron-methyl, penoxsuam and bentazone is
1-10:1-5:20-100.The weight ratio of the preferred proxazuron-methyl, penoxsuam and bentazone is 5:1:100.
Proxazuron-methyl described in mixed herbicide of the present invention, penoxsuam and bentazone are in the composition
Total weight percentage composition is 1-95%.The preferred proxazuron-methyl, penoxsuam and bentazone in the composition total
Weight percentage is 25-65%.
The present composition can be prepared into adaptation dosage form, preferred dosage form wettable powder with agriculturally acceptable auxiliary combination
Agent dispersible has one of suspending agent, suspending agent, granule, missible oil, microemulsion, aqueous emulsion, water dispersible granules etc..It is wettable
Property pulvis, missible oil, suspending agent, oil-suspending agent, microemulsion, aqueous emulsion, suspended emulsion, water dispersible granules etc..It is of the present invention
Auxiliary agent includes emulsifier, dispersing agent, wetting agent, binder, disintegrating agent, thickener, stabilizer, antifreezing agent, defoaming agent filler etc..
It is selected from the common auxiliary material in this field.
Mixed herbicide of the present invention is used for the purposes of management of weeds.It is preferred for paddy field, wheatland grass family, wealthy
Leaf weeds and nutgrass flatsedge, for example, it is barnyard grass, semen euphorbiae, wild avena sativa, Monochoria vaginalis, clearvers, Chinese celery, herba setariae viridis, purslane, herba digitariae, different
Type nutgrass flatsedge, water amaranth, bog pondweed etc..
The present invention obtains following advantageous effects:
Composition of the present invention uses the active ingredient combinations of three kinds of different role mechanism, can effectively reduce weeds
The generation of drug resistance expands degrass spectrum；Can prevent and kill off simultaneously barnyard grass, semen euphorbiae, Monochoria vaginalis, difformed galingale herb, Monochoria vaginalis, water amaranth,
Bog pondweed etc..
Herbicidal combinations of the present invention have significant synergies, and Herbicidal combinations field of the present invention is anti-
Effect is higher compared to the field efficacy of single dose, binary composition, can effectively reduce the administration dosage of active constituent, reduces environment
Pollution.
Specific embodiment
Below with reference to embodiment, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Embodiment 1: 28% proxazuron-methyl penoxsuam bentazone aqueous emulsion
Embodiment 2: 35% proxazuron-methyl penoxsuam bentazone suspending agent
Embodiment 3: 60% proxazuron-methyl penoxsuam bentazone wettable powder
Embodiment 4: 53% proxazuron-methyl penoxsuam bentazone water dispersible granules
Biological test one: proxazuron-methyl, penoxsuam and bentazone are to barnyard grass indoor toxicity test.
Test method: selection grows consistent weeds barnyard grass and is colonized, and does cauline leaf process, and water drenching is after blade is dry
Carry out cauline leaf spraying treatment.After processing 30 days, fresh weight is measured, calculates preventive effect.
Herbicide associated form is evaluated according to Colby method.Evaluation criterion: as E ﹣ E0 > 10%, it is expressed as synergistic effect；
As ﹣ 10%≤E ﹣ E0≤10%, summation action is shown as；As E ﹣ E0 < ﹣ 10%, antagonism is shown as.
1 proxazuron-methyl of table, penoxsuam and bentazone compounding are to barnyard grass indoor toxicity test
As seen from the above table, proxazuron-methyl, penoxsuam and bentazone compounding have apparent synergistic effect to barnyard grass,
Three kinds of substances, which are applied in combination, can be effectively reduced Pesticide use dosage.
Biological test two: proxazuron-methyl, penoxsuam and bentazone compounding are to paddy field weed field efficacy.
Subjects: barnyard grass, semen euphorbiae, Monochoria vaginalis, difformed galingale herb, Monochoria vaginalis, water amaranth, bog pondweed etc..
Test medicine: embodiment 1-4 medicament and comparison medicament
Test method: according to experimental plot area, having weighed medicament, and be watered and be diluted, and weeds are in the 2-3 leaf phase,
It is carried out cauline leaf 1 time by spraying using backpack sprayer, fresh weight preventive effect after investigation 30 days, and the activity of weeding of more various medicaments.It is anti-
Imitate (%)=[(clear water control group weeds fresh weight-processing group weeds fresh weight)/clear water group weeds fresh weight] * 100%.
2 proxazuron-methyl of table, penoxsuam and bentazone compounding are to paddy field weed field efficacy
As seen from the above table, compared with single dose, proxazuron-methyl, penoxsuam and bentazone compounding application, which can expand, to be removed
Grass spectrum, and its control efficiency to weeds can be significantly improved, it has significant synergies, can effectively lower applying for pesticide
With dosage, reduce environmental pollution；And field observation is to crop safety.
The above is only a preferred embodiment of the present invention, to those skilled in the art, this hair is not being departed from
It under the premise of bright raw material, can be suitably modified, these are improved also within protection scope of the present invention.
