Abstract
The invention discloses a kind of mixed herbicide containing imazamox Yu haloxyfop-r-methyl, with imazamox and haloxyfop-r-methyl as principle active component, wherein imazamox is 0.1～80 with the mass ratio of haloxyfop-r-methyl to the herbicide：0.1～80.Application of the mixed herbicide of the present invention in Soybean Field postemergence weed control, have the advantages that wide spectrum, quick-acting, efficient, low toxicity, safety and environmental protection.
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 haloxyfop-r-methyl, the herbicidal composition can be applicable to Peanut Fields weeding.
Background technology
Imazamox (imazamox), chemical name：(RS) -2- (4- isopropyl-4-methyl -5- oxygen -2- imidazolines -
2- yls) -5- methoxy Nicotinicum Acidums.The herbicide is the inhibitor of acetolactate synthestase (ALS), i.e., by suppressing to plant
The acetolactate synthestase of thing, prevents 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
Raw sowthistle, 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 after dispenser in soil, thus to most succession crops
Safety.But when which is used alone, drug action is not notable.
Haloxyfop-r-methyl (haloxyfop-P-methyl), also known as smart cover grass energy, chemical name：[(3- is chloro- for 4- for 2-
5- trifluoromethyl -2- pyridine epoxides) phenoxy group] propionic acid, belong to phenoxy carboxylic acid herbicides.Can be very after haloxyfop-r-methyl dispenser
Absorbed by the blade of grassy weed soon, and conducted to whole plant, suppress plant meristem growth, so as to kill weeds.
The dispenser phase is long, to emerging after be respectively provided with to the annual and perennial grassy weed of tiller, heading initial stage
Really.To various broad leaf crop high safeties under normal service condition.Remain to show excellent weeding effect under low temperature, drought condition
Really.Can be used for the broad leaf crop such as soybean, cotton, peanut, rape and wild cabbage field preventing and treating amur foxtail, barnyard grass, lady's-grass, green bristlegrass, ox
The annual and perennial grassy weed such as muscle grass, wild oat, reed, Bermuda grass, invalid to broad leaved weed and nutgrass flatsedge.
In recent years, due to the excessive use of herbicide, make weeds increasing to the resistance of agricultural chemicals.And imazamox,
When haloxyfop-r-methyl is used alone as single dose, weed control spectrum is narrow, and drug action is undesirable, so as to cause weed control efficacy
Reduce year by year.
Content of the invention
It is an object of the invention to provide a kind of mixed herbicide containing imazamox Yu haloxyfop-r-methyl.
It is a further object of the present invention to provide application of the herbicide in Soybean Field weeding.
A kind of mixed herbicide containing imazamox Yu haloxyfop-r-methyl, the herbicide is with imazamox and height
Effect haloxyfop-P-methyl is principle active component, and wherein imazamox is 0.1～80 with the mass ratio of haloxyfop-r-methyl：
0.1～80.
In the present invention, the imazamox in mixed herbicide and haloxyfop-r-methyl can be 0.1 in mass ratio～
80：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～
5th, 1～30：1st, 1～20：1st, 2.5～14：1 etc..In another kind of scheme, imazamox can be selected with haloxyfop-r-methyl

In mixed herbicide of the present invention, imazamox and quality hundred of both haloxyfop-r-methyls in herbicide
Divide than being 1～85%, preferably 6～75%, further preferred 20～75%.
The mixed herbicide of the present invention, with imazamox and haloxyfop-r-methyl as principle active component, with agricultural chemicals
Auxiliary agent is configured to any one formulation that allow on agricultural chemicals, i.e., except imazamox and efficient fluorine pyrrole first in the mixed herbicide
Outside the active ingredients such as standing grain spirit, the auxiliary agent allowed on pesticidal preparations, including but not limited to conventional surfactants, increasing can also be added
Thick dose, solvent or solid packing etc.；The formulation that the mixed herbicide is processed into can be missible oil, suspending agent, aqueous emulsion, micro emulsion
Agent, wettable powder, water dispersible granules etc..
In terms of the mixed herbicide of the present invention can be applicable to Soybean Field weeding, grass in Soybean Field is prevented and kill off especially is applied
In terms of section weeds or broad leaved weed.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, excellent with broad weed-killing spectrum, instant effect, efficient, low toxicity, the low, safety and environmental protection of residual etc.
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 pass through two kinds of different mechanism and kill weeds so that weeds
Resistance produces speed and reduces, and effective ingredient consumption is reduced, 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), high
Effect haloxyfop-P-methyl is grown by suppressing plant meristem, so as to kill weeds.Both mechanisms are different, and both mix
Afterwards, herbicidal spectrum is wider, can prevent and kill off grassy weed and broad leaved weed in Soybean Field.
3rd, safe.As the use content of various active ingredients is reduced, medicament is made to improve the premise of drug effect
Under, residues of pesticides are reduced, it also avoid also being improved soybean and succession crop security, it is to avoid agricultural chemicals is to people
Livestock products give birth to the possibility of residual hazard.

1) toxicity determination test
Using imazamox (A) and haloxyfop-r-methyl (B) different ratio, its co-toxicity coefficient to lady's-grass is determined.
Test method：The seed of quantitative lady's-grass is seeded in the Disposable paper cup of 9cm respectively, in per glass sowing 10～
15 seeds, cultivate in illumination box, when 3～6 leaf phase of lady's-grass, carry out at spraying in crawler crop spray
Reason.Continue culture after process in greenhouse, routine observation respectively processes the preventive effect to weeds, weighs miscellaneous after each process after 30d
Careless fresh weight, by the method that the nineteen sixties such as Sun Yunpei propose, calculates 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 shows that two kinds of active principles are addition between 80-120
Less than 80, effect, co-toxicity coefficient show that two kinds of active principles have antagonism.Measurement result is as shown in table 1.
