Abstract
The invention discloses a weeding composition containing dicamba and aclonifen, and an application thereof. Effective components of the weeding composition comprise dicamba and aclonifen, and a mass ratio of dicamba to aclonifen is 1-60:1-60. The weeding composition can be used for winter wheat field post-emergence weeding, and especially has a substantial control effect on grassy and broad leaf weeds in the winter wheat field. Compared with single doses, the weeding composition has the advantages of drug effect improvement, weed resistance delaying, broad weeding spectrum, long persistent period, and safety to winter wheat and later crops.
Description
Technical field
The invention belongs to technical field of pesticide, especially weed killer herbicide field, be specifically related to the binary built Herbicidal combinations of a kind of dicamba and aclonifen, this Herbicidal combinations can be applicable to winter wheat field postemergence weed control.
Background technology
Dicamba, has another name called wheat straw prestige; Dicamba.The chloro-O-Anisic Acid of chemical name: 3,6-bis-, structural formula is:
Dicamba belongs to hormone herbicide.There is Uptake and translocation effect, have remarkable preventive effect to annual and perennial broadleaf weed.Dicamba is used for spraying after seedling, and medicament very soon by the leaf of weeds, stem, root absorption, can be conducted by phloem and xylem up and down, focuses mostly at meristematic tissue and the vigorous position of metabolic activity, hinders the normal activity of plant hormone, thus make it dead.Namely there will be lopsided curling symptom with rear general 24h broad leaved weed, 15 ~ 20d is dead.
Aclonifen, chemical name: 2-chloro-6-nitro-3-phenoxyaniline, belongs to diphenyl ether herbicide, structural formula:
Aclonifen is proporphyrinogen oxidase inhibitor.After aclonifen is used, deposit one deck medicine film at soil surface, when grassy weed and broad leaved weed penetrate soil surface, weed killer herbicide respectively by the tender shoots of seedling, (under) plumular axis or coleoptile absorb, after sucking several days, seedling just turns yellow, growth retardation, finally dead.Must farming be avoided after dispenser, because the weed killer herbicide film of soil surface must keep complete, just have best activity of weeding, weed killer herbicide is mixed in soil and then reduces herbicidal efficacy significantly.Aclonifen is to the dependence of soil moisture, all less than other weed killer herbicide of great majority.
Current winter wheat field weed killer herbicide limit by crop safety, herbicide spectrum is also limited, be used alone the generation that a kind of weed killer herbicide single dose can not control winter wheat field weeds completely effectively, moreover some weed killer herbicide is due to water-soluble large or the field lasting period is oversize, consumption is excessive or the uneven residual hazard all easily caused this season crop or succession crop of dispenser.Therefore, the present invention selects herbicide to compose different, be made into mixture after the dicamba of pluses and minuses complementation and aclonifen two kinds of suitable decrements of weed killer herbicide to use, so both expand herbicide spectrum, significantly improve herbicidal effect, it also avoid and poisoning and the possibility to succession crop generation residual hazard are produced to this season crop.
Summary of the invention
The object of this invention is to provide a kind of Herbicidal combinations containing dicamba and aclonifen.
Another object of the present invention is to provide the application of this Herbicidal combinations in winter wheat field weeding.
Containing a Herbicidal combinations for dicamba and aclonifen, it is characterized in that this Herbicidal combinations with dicamba and aclonifen for active ingredient, the mass ratio of dicamba and aclonifen is 1 ~ 60:1 ~ 60.The mass ratio of preferred dicamba and aclonifen is 1 ~ 60:1 ~ 30, more preferably 29 ~ 60:1 ~ 5, most preferably is 12 ~ 59:1.
In Herbicidal combinations, both dicamba and the aclonifen mass percentage in Herbicidal combinations is 1 ~ 80%, and preferred mass percentage composition is 10 ~ 65%, and further preferred mass percentage composition is 30 ~ 65%.
In the binary built composition of dicamba of the present invention and aclonifen, except dicamba and aclonifen active ingredient, the auxiliary agents such as conventional surfactants, thickener, solvent or the solid packing that pesticidal preparations allows can also be added and be mixed with any one formulation that agricultural chemicals allows.Preferably be processed into missible oil, suspending agent, aqueous emulsion, microemulsion, water dispersion granule, wetting powder etc.
Herbicidal combinations of the present invention can be applied in winter wheat field postemergence weed control, particularly has remarkable result preventing and kill off in winter wheat field application in grass family and broad leaved weed.
Herbicidal combinations of the present invention has the following advantages:
1, activity of weeding is high.Herbicidal combinations of the present invention can kill weeds by two kinds of different mechanism, makes Weed Resistance produce speed and reduces, greatly improve the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Aclonifen is broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and dicamba is the weed killer herbicide preventing and kill off broad leaved weed.After both mixing, the control to multiple grassy weed and broad leaved weed can be improved.
3, Weed Resistance is delayed.Herbicidal combinations of the present invention, by binary built, reduces weeds to the resistance of medicament, and improves the preventive effect of antagonism weeds, thus extend the service life of medicament.
4, safety is high.Because its using dosage is under control, make medicament under the prerequisite that improve drug effect, it have also been obtained raising to the safety of winter wheat and succession crop.
Herbicidal combinations of the present invention, is applied to winter wheat field postemergence weed control, and it can prevent and kill off various grass family and broad leaved weed in winter wheat field, under the prerequisite that improve drug effect, all has safety to winter wheat and succession crop.
Therefore, Herbicidal combinations of the present invention can be applied in the weed killer herbicide for the preparation of winter wheat field postemergence weed control, particularly applies in for the preparation of the weed killer herbicide preventing and kill off grass family and broad leaved weed in winter wheat field.
