Description
Technical field
The invention belongs to pesticides application technical fields, and in particular to one kind is containing glyphosate, cyhalofop-butyl Yu metamifop
Ternary weeding composition and its application.
Background technology
Chemical weed control is agriculturally effectively to control the effective means of weeds, but make due to a large amount of single herbicide
With causing resistance weed constantly to enhance, the amount of application of herbicide continues to increase, and serious pollution is caused to environment；In addition
The herbicide controlling spectrum of single variety herbicide is limited, and a variety of weeds cannot be prevented and kill off simultaneously using single herbicide, results in the need for repeatedly
Dispenser causes a large amount of wastes of manpower and materials.Being used in mixed way between herbicide can solve that pesticide single dose herbicide controlling spectrum is narrow, effect
The problem of difference, and it is used interchangeably the generation for capableing of retarding action object drug resistance between different pesticides, have ideal
Using effect, therefore the compounding of pesticide is current research focus in the field of pesticide between different role mechanism.
Glyphosate is a kind of organophosphorus herbicide, and the mechanism of action is mainly by inhibiting enolpyruvyl shikimene phosphoric acid
The activity of synzyme destroys conversion of the shikimene to phenylalanine, tyrosine, tryptophan, to make protein synthesis by dry
It disturbs and causes plant dead；Very to deep root perennial weeds and annual and biennial grass family, Cyperaceae and broad leaved weed
Effectively.The most prominent feature of glyphosate is can be absorbed by cauline leaf in conduction to underground rhizome and tiller downwards, to weeds the following group
It is extremely strong to knit destructive power.
Cyhalofop-butyl belongs to aryloxyphenoxypropionic class herbicide, is mainly used for preventing and kill off important grassy weed；
Can also prevent and kill off, lady's-grass, Paspalum distichum, green bristlegrass, eleusine indica, amur foxtail etc..It is invalid to sedge weed and broad leaved weed.
Metamifop is aryloxyphenoxypropanoates class herbicide, can be fabulous to prevent and kill off most of annual gramineaes miscellaneous
Grass can effectively prevent and kill off rice terrace main weeds, such as barnyard grass, moleplant seed, lady's-grass and ox unlike most of such herbicides
Muscle grass, is mainly used for transplanting and direct sowing rice field weeding.
There are many document compounded Yu metamifop in relation to cyhalofop-butyl in the prior art, such as：Patent document
(CN102696630A) a kind of Herbicidal combinations active constituent is disclosed to be made of metamifop and cyhalofop-butyl, to barnyard grass,
Moleplant seed, eleusine indica have good preventive effect.Patent document (CN103583531A) discloses one kind and preventing and kill off rice terrace grass family
The Herbicidal combinations of weeds, active ingredient are made of penoxsuam, cyhalofop-butyl, metamifops.Patent document
(CN104585205A) a kind of Herbicidal combinations, active constituent You metamifops, cyhalofop-butyl and halosulfuronmethyl are disclosed
Composition.Patent document (CN105394049A) discloses a kind of Herbicidal combinations, active constituent You metamifops, cyhalofop-butyl
It is formed with bentazone.Patent document (CN106472519A) discloses a kind of Herbicidal combinations, active constituent by dichloro quinolinic acid,
Cyhalofop-butyl is He metamifop forms.But there is no glyphosates and cyhalofop-butyl Huo metamifop binary in the prior art
Compound no pertinent literature report, the more relevant report without glyphosate, cyhalofop-butyl and three metamember of metamifop compounding.
The present invention mainly studies glyphosate, cyhalofop-butyl Yu repercussion effect between metamifop.
Invention content
The purpose of the present invention is to provide the Herbicidal combinations with synergistic function, can effectively reduce active constituent
Dosage plays and slows down herbicide resistance generation, expands the purpose of herbicide controlling spectrum, can effectively prevent and kill off grassy weed and broad-leaved is miscellaneous
Grass.
The present invention provides following technical scheme
A kind of ternary weeding composition containing glyphosate, cyhalofop-butyl Yu metamifops, active constituent is by glyphosate, cyanogen
Fluorine grass Zhi is He metamifop forms, and the glyphosate, cyhalofop-butyl are He the weight ratio of metamifop is 1-100:1-50:1-
50。
Preferably, in the ternary weeding composition, the glyphosate, cyhalofop-butyl He metamifop weight
Than for 1-80:1-30:1-30.
Further preferably, the weight ratio of the glyphosate, cyhalofop-butyl He metamifop is 4-72:2-20:5-25.
The present invention also provides a kind of pesticidal preparations including the ternary weeding composition, the pesticidal preparations medium-height grass is sweet
The total weight percentage composition of phosphine, cyhalofop-butyl He metamifop in pesticidal preparations is 2-85%, remaining is can in Pesticide Science
The auxiliary material of receiving.
Preferably, the total weight percentage composition of the glyphosate, cyhalofop-butyl He metamifop in pesticidal preparations
For 15-75%.
Preferably, the dosage form of the pesticidal preparations be wettable powder, missible oil, suspending agent, oil-suspending agent, microemulsion,
Aqueous emulsion or water dispersible granules.
Preferably, acceptable auxiliary material is emulsifier, dispersant, wetting agent, binder, disintegration in the Pesticide Science
At least one of agent, thickener, stabilizer, antifreezing agent, antifoaming agent and filler.
The present invention also provides the ternary weeding composition be used for management of weeds purposes, such as forest, orchard,
Bare place, pasture, tea place, rubber plantation, farmland etc.；It is preferred for grass family and broad leaved weed；The weeds include barnyard grass, a thousand pieces of gold
Son, Monochoria vaginalis, lady's-grass, green bristlegrass, eleusine indica, chickweed, Siberian cocklebur, Horseweed Herb etc..
Compared with prior art, the present invention obtains following advantageous effects：
(1) Herbicidal combinations of the invention have significant synergies, can be effective compared with single dose, binary combination
Its preventive effect is improved, the administration dosage of active constituent can be effectively reduced, reduced environmental pollution.
(2) herbicidal active component of three kinds of different role mechanism is applied in combination the present invention, can effectively reduce the anti-medicine of weeds
Property generation, expand herbicide controlling spectrum；Prevention when available for grassy weed and broad leaved weed.
Specific implementation mode
The specific implementation mode of the present invention is described in detail with reference to embodiment, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
Embodiment 1：Glyphosate, cyhalofop-butyl Yu metamifop to eleusine indica indoor bioassay.
