Abstract
The invention discloses a mixed herbicide containing imazamox and fluazifop p-butyl. Imazamox and fluazifop p-butyl are the main effective components of the herbicide. The mass ratio of imazamox to fluazifop p-butyl is 0.1-80: 0.1-80. The provided mixed herbicide is used in the post-emergence in soybean fields to kill weed, and has the advantages of wide weed killing spectrum, rapid effect, high efficiency, low toxicity, safety, and environment-friendliness.
Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field and in particular to a kind of containing imazamox with
The binary built agent of efficient fluazifop, this herbicidal composition can be applicable to Soybean Field postemergence weed control.
Background technology
Imazamox (imazamox), chemical name：(RS) -2- (4- isopropyl-4-methyl -5- oxygen -2- imidazoline -
2- yl) -5- methoxy Nicotinicum Acidum.This herbicide is the inhibitor of acetolactate synthestase (ALS), is planted by suppression
The acetolactate synthestase of thing, stops the biosynthesis of branched-chain amino acid such as valine, leucine, isoleucine, final destruction
The synthesis of protein, interference DNA synthesis and cell division and growth.Imazamox can effectively prevent and treat most of annual grass
Section and broad leaved weed, such as barnyard grass, green bristlegrass, setaria glauca, amur foxtail, millet, moleplant seed, lady's-grass, dayflower (before 3 leaf phases), dragon
Certain herbaceous plants with big flowers, piemarker, Amaranthus retroflexus, lamb's-quarters, little lamb's-quarters, Siberian cocklebur, elscholtiza, water spine pin, bur beggar-ticks, chickweed, willow leaf thorn smartweed, weasel hemp nettle etc., to for many years
The sowthistle of life, field thistle etc. have inhibitory action.Imazamox is applied to Soybean Field after seedling cauline leaf process, is imidazolone type
Short residual kind in herbicide, the medicament overwhelming majority decomposition failure in soil after dispenser, thus to most succession crops
Safety.But when it is used alone, drug action is not notable.
Efficient fluazifop (fluazifop-P), chemical name：(R) 2- [4- (5- trifluoromethyl -2- pyridine epoxide) benzene
Epoxide] butyl propionate.This herbicide belongs to inner sucting conduction type cauline leaf process herbicide, is aliphatic acid synthetic inhibitor, to grass
Section weeds have very strong lethal effect, to broad leaf crop safety.Can be used for preventing and kill off soybean, cotton, potato, tobacco, flax,
The annual and perennial grassy weed of vegetables, fields of peanut and other crops, the main portions that weeds absorb medicament are stem and leaf, apply
After soil, medicament also can pass through Root Absorption, and after 48h, poisoning symptom in weeds, stop growing first, therewith bud and dividing of saving
Withered spot in raw tissue, and lobus cardiacus and other blade positions gradually become purple or yellow, withered death.
In recent years, due to the excessive use of herbicide, make weeds increasing to the resistance of agricultural chemicals.And imazamox,
When efficient fluazifop is used alone as single dose, weed control spectrum is narrow, and drug action is undesirable, thus cause weed control efficacy by
Year reduces.
Content of the invention
It is an object of the invention to provide a kind of mixed herbicide containing imazamox and efficient fluazifop.
It is a further object of the present invention to provide application in Soybean Field weeding for this herbicide.
A kind of mixed herbicide containing imazamox and efficient fluazifop, this herbicide is with imazamox and smart pyrrole
Fluorine diclofop-methyl is principle active component, and imazamox is 0.1～80 with the mass ratio of efficient fluazifop：0.1～80.
In the present invention, the imazamox in mixed herbicide and efficient fluazifop can be 0.1～80 in mass ratio：
Arbitrarily adjust in the range of 0.1～80, the such as mass ratio of the two is 1～80：1～80,1～60：1～60,1～40：1～5,1
～30：1st, 1～20：1st, 2.5～14：1 etc..In another kind of scheme, imazamox and efficient fluazifop can select down

In mixed herbicide of the present invention, imazamox and percent mass in herbicide for both efficient fluazifops
Than for 1～85%, preferably 6～75%, further preferred 20～75%.
The mixed herbicide of the present invention, with imazamox and efficient fluazifop as principle active component, is helped with agricultural chemicals
Agent is configured to any one formulation allow on agricultural chemicals, that is, except imazamox and efficient fluazifop in this mixed herbicide
Outside etc. active ingredient, the auxiliary agent allowing, including but not limited to conventional surfactants, thickening can also be added on pesticidal preparations
Agent, solvent or solid packing etc.；The formulation that this mixed herbicide is processed into can be missible oil, suspending agent, aqueous emulsion, microemulsion,
Wettable powder, water dispersible granules.
The mixed herbicide of the present invention can be applicable to Soybean Field weeding aspect, especially applies grass in preventing and kill off Soybean Field
Section weeds or broad leaved weed aspect.This herbicide has the advantages that broad weed-killing spectrum, instant effect, remains low, low toxicity, safety and environmental protection,
It is the soybean crops chemical herbicide of high-quality.
The combinations of herbicides of the present invention, have broad weed-killing spectrum, instant effect, efficiently, low toxicity, to remain low, safety and environmental protection etc. excellent
Point, it is possible to reduce pesticide usage amount, reduces residues of pesticides, Environmental compatibility is good, to person poultry safety the advantages of, be the soybean of high-quality
Crop chemistry herbicide.Compared with prior art, the present invention has following features：
1st, activity of weeding is high.The Herbicidal combinations of the present invention can kill weeds by two kinds of different mechanism so that weeds
Resistance produces speed and reduces, and effective ingredient consumption reduces, but drastically increases the removing activity of herbicide.
2nd, herbicidal spectrum is wide, and the lasting period is long.Imazamox herbicide is the inhibitor of acetolactate synthestase (ALS), essence
Fluazifop is aliphatic acid synthetic inhibitor.Both mechanisms are different, and after both mixing, herbicidal spectrum is wider, can in case
Except grassy weed and broad leaved weed in Soybean Field.
3rd, safe.Due to reducing using content of various active ingredients, medicament is made to improve the premise of drug effect
Under, reduce residues of pesticides, it also avoid soybean and succession crop security are also improved, it is to avoid agricultural chemicals is to people
The possibility of the raw residual hazard of livestock products.

Embodiment 9
1) toxicity determination test
Using imazamox (A) and efficient fluazifop (B) different ratio, measure its co-toxicity coefficient to lady's-grass.
Test method：The seed of quantitative lady's-grass is seeded in the Disposable paper cup of 9cm respectively, in every glass sowing 10～
15 seeds, cultivate in illumination box, when 3～6 leaf phase of lady's-grass, make to carry out at spraying on composition spray in crawler type
Reason.Continue culture in greenhouse after process, routine observation respectively processes the preventive effect to weeds, weigh miscellaneous after each process after 30d
Careless fresh weight, the method proposing by nineteen sixties such as Sun Yunpei, calculate its toxicity regression curve and co-toxicity coefficient.Co-toxicity coefficient is more than
120, show that two kinds of active principles have synergistic effect, co-toxicity coefficient, between 80-120, shows that two kinds of active principles are to be added
Effect, co-toxicity coefficient is less than 80, shows that two kinds of active principles have antagonism.Measurement result is as shown in table 1.
