Abstract
The invention discloses a dicamba and pyrazosulfuron-ethyl herbicidal composition and application thereof, the herbicidal composition comprises dicamba and pyrazosulfuron-ethyl as main effective components, and the mass ratio of dicamba to pyrazosulfuron-ethyl is 1-60:1-60. The herbicidal composition can be used for paddy field after-seedling weeding, is especially used to control gramineae and broadleaf weeds in paddy fields, and has a significant effect. The herbicidal composition has the advantages of delaying weed resistance, wide herbicidal spectrum, long lasting period, and safety of the paddy and afterreap crops on the premise of improvement of the efficacy of the herbicide compared with a single agent.
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 pyrazosulfuron, this Herbicidal combinations can be applicable to paddy 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.
Pyrazosulfuron, chemical name: 5-(4,6-dimethoxypyridin base-2-carbamoylamino sulphonyl-1-methylpyrazole-4-carboxylic acid, ethyl ester; 5-(4,6-dimethoxypyridin base-2-carbamyl sulfonamides)-1-methylpyrazole base-4-ethyl ester; 5-(3-(4,6-dimethoxypyridin-2-base) ureido sulfuryl)-1-methylpyrazole-4-carboxylic acid, ethyl ester, belongs to sulfonylurea herbicide, structural formula:
Pyrazosulfuron inhales selectivity acetolactate synthestase (ALS) weed killer herbicide in sulfonylurea high activity.Medicament is mainly absorbed by the young shoot of plant, root and cauline leaf and conducts rapidly in plant corpus.Suppress amino acid whose biosynthesis in plant corpus, the bud of weeds and root are stopped growing growth very soon, and whole strain is withered subsequently.Though after dispenser, weeds, still in green, grow and are suppressed, lose the competitiveness with paddy rice sometimes.
Current herbicide for paddy field 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 paddy field weed 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 pyrazosulfuron 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 pyrazosulfuron.
Another object of the present invention is to provide the application of this Herbicidal combinations in agent for removing grass in paddy field.
A kind of Herbicidal combinations containing dicamba and pyrazosulfuron, it is characterized in that this Herbicidal combinations with dicamba and pyrazosulfuron for active ingredient, the mass ratio of dicamba and pyrazosulfuron is 1 ~ 60:1 ~ 60, be preferably 1 ~ 60:1 ~ 30, more preferably 29 ~ 60:1 ~ 5, most preferably are 12 ~ 59:1.
In Herbicidal combinations, both dicamba and the pyrazosulfuron 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 pyrazosulfuron, except dicamba and pyrazosulfuron 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 paddy field postemergence weed control, particularly has remarkable result preventing and kill off in paddy 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.Pyrazosulfuron 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 paddy rice and succession crop.
Herbicidal combinations of the present invention, is applied to paddy field postemergence weed control, and it can prevent and kill off various grass family and broad leaved weed in paddy field, under the prerequisite that improve drug effect, all has safety to paddy rice and succession crop.
Therefore, Herbicidal combinations of the present invention can be applied in the weed killer herbicide for the preparation of paddy 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 paddy field.
