Abstract
The invention discloses a mixed herbicide containing imazapic and sethoxydime. The herbicide takes imazapic and sethoxydime as main active ingredients, wherein the mass ratio of the imazapic to sethoxydime is (0.1-80):(0.1-80). The mixed herbicide disclosed by the invention can be applied to post-seedling weed control in a peanut field and has the advantages of broad spectrum, quick-acting effect, high efficiency, low toxicity, safety, environment friendliness and the like.
Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field and in particular to a kind of containing AC 263222 with
The binary built agent of sethoxydim, this herbicidal composition can be applicable to Peanut Fields postemergence weed control.
Background technology
AC 263222 (imazapic), chemical name: (rs) -2- (4- isopropyl-4-methyl -5- oxygen -2- imidazoline -
2- yl) -5- methylnicotinic acid.This herbicide is acetolactate synthestase (als) or the inhibitor of acetic acid hydroxy acid synzyme (ahas),
Pass through to suppress the acetolactate synthestase of plant, stop the biosynthesiss of branched-chain amino acid, thus destroying the synthesis of protein,
Interference dna synthesis and cell division and growth, ultimately cause plant dead.All there is good preventive effect to single, double cotyledon weeds, not only
Weeds aerial partss can be killed well, and the root to weeds underground part and subterraneous stem also have stronger preventive effect.Mainly
For Peanut Fields early stage postemergence weed control, sedge weed, millet are belonged to by weeds, Semen Cassiae, descurainia sophia (l.) webb ex prantl etc. and have good activity.
Sethoxydim (sethoxydim), also known as Sethoxydin, chemical name: 2- [1- (ethoxy imino) butyl] -5- [2-
(ethylmercapto group) propyl group] -3- hydroxy cyclohexylphenyl -2- ketenes, belong to cyclohexenone analog herbicide, be the very strong inner sucting conduction type stem of selectivity
Leaf inorganic agent, can be absorbed rapidly by grassy weed stem and leaf, and is transmitted to top and internode separate living tissue, so that cell division is destroyed
Lethal.Sethoxydim is mainly used in preventing and treating annual and perennial grassy weed, can be used for Semen sojae atricolor, Cotton Gossypii, Brassica campestris L, Semen arachidis hypogaeae, horse
The crops such as bell potato, Radix Betae, Helianthi, Caulis et Folium Lini and orchard, prevent and kill off barnyard grass, wild oat, Herba Setariae Viridis, amur foxtail, Herba Digitariae, Herba Eleusines Indicae etc.
Grassy weed, invalid to broad leaved weed.
In recent years, due to the excessive use of herbicide, make weeds increasing to the resistance of pesticide.And AC 263222,
When sethoxydim is used alone as single dose, weed control spectrum is narrow, and drug action is undesirable, thus causing weed control efficacy to drop year by year
Low.
Content of the invention
It is an object of the invention to provide a kind of mixed herbicide containing AC 263222 and sethoxydim.
It is a further object of the present invention to provide application in Peanut Fields weeding for this herbicide.
A kind of mixed herbicide containing AC 263222 and sethoxydim, this herbicide is based on AC 263222 and sethoxydim
Want effective ingredient, wherein AC 263222 and the mass ratio of sethoxydim are 0.1～80:0.1～80.
In the present invention, the AC 263222 in mixed herbicide and sethoxydim can mass ratio be 0.1～80:0.1～
Arbitrarily adjust in the range of 80, for example the mass ratio of the two be 1～80:1～80,1～60:1～60,1～40:1～5,1～30:
1st, 1～20:1,2.5～14:1 etc..In another kind of scheme, AC 263222 and sethoxydim can select in following mass ratioes
Any one or more: 0.1:80,0.5:80,1:80,1:79,1:78,1:77,1:76,1:75,1:74,1:73,1:72,1:

In mixed herbicide of the present invention, AC 263222 and mass percent in herbicide for both sethoxydims are 1
～85%, preferably 6～75%, further preferred 20～75%.
The mixed herbicide of the present invention, with AC 263222 and sethoxydim as principle active component, is prepared with insecticides adjuvant
Any one dosage form allowing is become on pesticide, that is, except AC 263222 and the effective ingredient such as sethoxydim in this mixed herbicide
Outward, the auxiliary agent allowing, including but not limited to conventional surfactants, thickening agent, solvent or solid can also be added on pesticidal preparations
Body filler etc.；The dosage form that this mixed herbicide is processed into can be cream, suspending agent, aqueous emulsion, microemulsion, wettable powder,
Water dispersible granules etc..
The mixed herbicide of the present invention can be applicable to Peanut Fields weeding aspect, especially applies grass in preventing and kill off Peanut Fields
Section weeds, broad leaved weed or dried tuber aspect.The advantages of this herbicide broad weed-killing spectrum, instant effect, residual low, low toxicity, safety and environmental protection,
It is the Peanut Crop 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 pesticide residues, Environmental compatibility is good, to person poultry safety the advantages of, be the Semen arachidis hypogaeae of high-quality
Crop chemistry herbicide.Compared with prior art, the present invention has a characteristic that
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.AC 263222 is acetolactate synthestase (als) synthetic inhibitor, sethoxydim
(sethoxydim) belong to cyclohexenone analog herbicide, can be absorbed rapidly by grassy weed stem and leaf, and be transmitted to top and internode
Separate living tissue, makes cell division destroy lethal.Both mechanisms are different, and after both mixing, herbicidal spectrum is wider, can prevent and kill off
Grassy weed, broad leaved weed and dried tuber in Peanut Fields.
3rd, safe.Due to reducing using content of various effective ingredient, medicament is made to improve the premise of drug effect
Under, reduce pesticide residues, it also avoid Semen arachidis hypogaeae and succession crop safety are also improved, it is to avoid pesticide is to people
The probability of the raw residual hazard of livestock products.

Embodiment 9
1) toxicity determination test
Using AC 263222 (a) and sethoxydim (b) different ratio, measure its co-toxicity coefficient to Herba Digitariae.
Test method: the seed of quantitative Herba Digitariae 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 Herba Digitariae, 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 substance have potentiation, co-toxicity coefficient, between 80-120, shows that two kinds of active substance are to be added
Effect, co-toxicity coefficient is less than 80, shows that two kinds of active substance have antagonism.Measurement result is as shown in table 1.
Table 1 toxicity measurement result
As can be seen from the above table, the co-toxicity coefficient after two kinds of active substance compound is both greater than 120, illustrates that the present invention has bright
Aobvious potentiation.
