Abstract
The invention discloses the acid of a kind of chloride Fampridine and the mixed herbicide of clopyralid, belong to technical field of pesticide.This herbicide with the acid of chlorine Fampridine with clopyralid for principle active component, the acid of chlorine Fampridine is 0.1～80:0.1～80 with the mass ratio of clopyralid.The mixed herbicide of the present invention application in bare place, orchard, forest land, pasture, lawn and wheat paddock postemergence weed control, there is instant effect, herbicide spectrum width, lasting period length, weeding thoroughly, remain the advantages such as low, low toxicity, safety and environmental protection, be the bare place of high-quality, orchard, forest land, pasture, lawn and wheat paddock chemical herbicide.
Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field, relate to the binary built agent of the acid of chlorine Fampridine and clopyralid.This herbicidal composition can be applicable to bare place, orchard, forest land, pasture, lawn and wheat paddock postemergence weed control.
Background technology
Chlorine Fampridine acid (aminopyralid), chemical name: 4-amino-3,6-dichloropyridine-2-carboxylic acid, chlorine Fampridine acid is a kind of pyridines herbicide, is widely used in the control of weeds of mountain region, grassland, lawn, plantation and bare place.Annual or perennial broadleaf weed can be prevented and treated.
Clopyralid (clopyralid), chemical name: 3,6-dichloropyridine-2-carboxylic acids, clopyralid is a kind of pyridines herbicide, after weeds dispenser, by blade or root absorption, dividing a word with a hyphen at the end of a line up and down in plant, pass to rapidly whole plant, the mechanism of action of its herbicide is the formation promoting plant nucleic acid, produce excessive ribonucleic, causing root growth excessive, stem and leaf growth are lopsided, nutrient consumption, vascular bundle transporting function is obstructed, and causes that weeds are dead.Its broad weed-killing spectrum, it is possible to effectively prevent and kill off annual grassy weeds and deep root perennial weeds.
Current chlorine Fampridine acid residue problem is serious, has been strictly limited in a lot of countries and regions and has made consumption and using method.In order to while reducing herbicide carryover, guarantee the herbicidal effect of medicament, the present invention selects herbicide to compose difference, it is made into mixture use after the chlorine Fampridine acid of pluses and minuses complementation and two kinds of suitable decrements of herbicide of clopyralid, so both expand herbicide spectrum, significantly improve herbicidal effect, it also avoid the probability that succession crop is produced residual hazard.
Summary of the invention
It is an object of the invention to provide the mixed herbicide of the acid of a kind of chloride Fampridine and clopyralid.
It is a further object of the present invention to provide the application in bare place, orchard, forest land, pasture, lawn and wheat paddock weeding of this herbicide.
A kind of mixed herbicide of chloride Fampridine acid and clopyralid, it is characterized in that this herbicide with chlorine Fampridine acid with clopyralid for principle active component, the mass ratio of the acid of chlorine Fampridine and clopyralid is 0.1～80:0.1～80, the mass ratio of the acid of preferred chlorine Fampridine and clopyralid is 1～60:1～60, it is most preferred that the mass ratio of the acid of chlorine Fampridine and clopyralid is 3:2～15.
In mixed herbicide, the acid of chlorine Fampridine is 1～85% with both clopyralids weight/mass percentage composition in herbicide, it is preferable that weight/mass percentage composition is 10～75%.
The mixed herbicide of the present invention, wherein the acid of chlorine Fampridine and clopyralid exist with the form of water soluble salt, and the water soluble salt of described chlorine Fampridine acid includes the water soluble salts such as sodium salt, potassium salt, ammonium salt, isopropyl amine salt, methylamine salt, dimethylamine salt, alcohol salt, triethanolamine salt, triisopropanolamine salt.
In the chlorine Fampridine acid of the present invention and the binary built preparation of clopyralid, except the acid of chlorine Fampridine is with clopyralid effective ingredient, it is also possible to add any one dosage form that the auxiliary agents such as the conventional surfactants, thickening agent, solvent or the solid packing that allow on pesticidal preparations are configured on pesticide to allow.Preferably it is processed into water preparation, wettable powder, water solube powder, water-soluble granule, water dispersible granules.
" % " of the present invention is weight/mass percentage composition.
The application in bare place, orchard, forest land, pasture, lawn and wheat paddock weeding of the mixed herbicide of chloride Fampridine of the present invention acid and clopyralid, in preventing and kill off bare place, orchard, forest land, pasture, lawn and wheat paddock, the application in various broad leaved weeds has remarkable result.
Compared to the prior art, beneficial effects of the present invention:
The mixed herbicide of the present invention, has instant effect, a herbicide spectrum width, lasting period length, weeding thoroughly, remain the advantages such as low, low toxicity, safety and environmental protection, be the bare place of high-quality, orchard, forest land, pasture and lawn chemical herbicide.
