Abstract
The invention discloses a mixed herbicide containing imazapic and fomesafen. The herbicide adopts the imazapic and the fomesafen as main active components, wherein the mass ratio of the imazapic to the fomesafen is (0.1 to 80) to (0.1 to 80). The mixed herbicide provided by the invention is applied in post-emergence weeding of a peanut field, and has the advantages of broad spectrum, quick effect, high efficiency, low toxicity, safety, environment protection 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 fomesafen, 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.
Fomesafen (fomesafen), chemical name: 5- (2- chloro-trifluoromethyl phenoxy)-n- methylsulfonyl -2-
Nitrobenzamide.It is a kind of diphenyl ether herbicide with high selectivity, be mainly used in preventing and kill off Semen sojae atricolor, Semen arachidis hypogaeae field wealthy
Leaf weeds and Rhizoma Cyperi, also have certain preventive effect to grassy weed, can be absorbed so as to withered and yellow death rapidly by weeds root leaf.
In recent years, due to the excessive use of herbicide, make weeds increasing to the resistance of pesticide.And AC 263222,
When fomesafen is used alone as single dose, weed control spectrum is narrow, and drug action is undesirable, thus causing weed control efficacy year by year
Reduce.
Content of the invention
It is an object of the invention to provide a kind of mixed herbicide containing AC 263222 and fomesafen.
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 fomesafen, this herbicide is with AC 263222 and fluorine sulfanilamide
Careless ether is principle active component, and wherein AC 263222 and the mass ratio of fomesafen are 0.1～80:0.1～80.
In the present invention, the AC 263222 in mixed herbicide and fomesafen can be 0.1～80 in mass ratio:
Arbitrarily adjust in the range of 0.1～80, for example the mass ratio of the two be 1～80:1～80,1～60:1～60,1～40:1～5,1
～30:1,1～20:1,2.5～14:1 etc..In another kind of scheme, AC 263222 and fomesafen can select following

In mixed herbicide of the present invention, AC 263222 and mass percent in herbicide for both fomesafens
For 1～85%, preferably 6～75%, further preferred 20～75%.
The mixed herbicide of the present invention, with AC 263222 and fomesafen as principle active component, with insecticides adjuvant
Any one dosage form allow is configured on pesticide, that is, except AC 263222 and fomesafen etc. have in this mixed herbicide
Outside effect composition, the auxiliary agent allowing can also be added on pesticidal preparations, including but not limited to conventional surfactants, thickening agent, molten
Agent or solid packing etc.；The dosage form that this mixed herbicide is processed into can be cream, suspending agent, aqueous emulsion, microemulsion, wettability
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.This herbicide has broad weed-killing spectrum, instant effect, remains low, low toxicity, safety and environmental protection etc.
Advantage, 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, fluorine sulfanilamide
Careless ether belongs to diphenyl ether herbicide, and both mechanisms are different, and after both mixing, herbicidal spectrum is wider, can prevent and kill off Peanut Fields
Middle grassy weed, broad leaved weed and dried tuber.
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 the different ratio of AC 263222 (a) and fomesafen (b), 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.
2) field control effectiveness test.
Reagent agent:

For studying thing: Semen arachidis hypogaeae
Fresh branches and leaves of peanut seedling grows fine, robust plant, no other pest and disease damages
Prevent and kill off object:
The weeds such as Herba Eleusines Indicae, Herba Galii Teneri, Rhizoma Cyperi.
Test method:
According to the area of experimental plot, the good various medicaments of precise, after being watered dilution, using knapsack sprayer, enter
Row even spraying, spraying is from the special Fan spray head of herbicide.It should be noted that medicinal liquid uniformly to be sprayed application to experimental plot during spraying
In, the spray of anti-Zhiduo County, drain spray phenomenon.
20d after medicine respectively after test, 40d observe weeds death condition, and the activity of weeding of relatively various medicaments.This
Outward, also will 1-15 days after medicine in observe the growing state consumption of every mu of effective ingredient (consumption be) of crop, to investigate medicine
Whether agent has poisoning to crop.
Embodiments of the invention preparation Herbicidal Testing Trials effect see table 2 (20d after medicine) and table 3 (40d after medicine)
Table 2 field control effectiveness test result (20d after medicine)
