Abstract
The invention discloses a mixed herbicide containing aminopyralid and clopyralid, belonging to the technical field of pesticides. The herbicide takes aminopyralid and clopyralid as main active ingredients, wherein the mass ratio of aminopyralid to clopyralid is (0.1-80) to (0.1-80). The mixed herbicide has the advantages of quickness in effect taking, wide weeding spectrum, long lasting period, thoroughness in weeding, low residues, low toxicity, safety, environment friendliness, and the like when being applied to post-emergence weeding on non-cultivated lands, forest lands, pastures and lawns and in orchards and wheat fields, and is a high-quality chemical herbicide applied to the non-cultivated lands, orchards, forest lands, pastures, lawns and wheat fields.
Description
Technical field
The invention belongs to technical field of pesticide, especially weed killer herbicide field, relate to the binary built agent of the acid of chlorine Fampridine and clopyralid.This herbicidal composition can be applicable to uncultivated area, orchard, forest land, pasture, lawn and wheat paddock postemergence weed control.
Background technology
Chlorine Fampridine acid (aminopyralid), amino-3, the 6-dichloropyridine-2-carboxylic acids of chemical name: 4-, the acid of chlorine Fampridine is a kind of pyridines weed killer herbicide, is widely used in the control of weeds of mountain region, grassland, lawn, plantation and uncultivated area.Annual or perennial broadleaf weed can be prevented and treated.
Clopyralid (clopyralid), chemical name: 3,6-dichloropyridine-2-carboxylic acid, clopyralid is a kind of pyridines weed killer herbicide, after weeds dispenser, by blade or root absorption, divide a word with a hyphen at the end of a line up and down in plant corpus, pass to rapidly whole plant, the mechanism of action of its herbicide is the formation promoting plant nucleic acid, produce excessive ribonucleic, cause root growth excessive, stem and leaf growth deformity, nutrient consumption, vascular bundle transporting function is obstructed, and causes weeds dead.Its broad weed-killing spectrum, can prevent and kill off annual weed and dark root perennial weed effectively.
Current chlorine Fampridine acid residue problem is serious, has been strictly limited usage amount and using method in a lot of countries and regions.In order to while minimizing herbicide carryover, guarantee the herbicidal effect of medicament, the present invention selects herbicide to compose different, be made into mixture and use after the chlorine Fampridine acid of pluses and minuses complementation and clopyralid two kinds of suitable decrements of weed killer herbicide, so both expand herbicide spectrum, significantly improve herbicidal effect, it also avoid possibility succession crop being produced to residual hazard.
Summary of the invention
The object of this invention is to provide the mixed herbicide of a kind of chloride Fampridine acid and clopyralid.
Another object of the present invention is to provide the application of this weed killer herbicide in uncultivated area, orchard, forest land, pasture, lawn and wheat paddock weeding.
The mixed herbicide of a kind of chloride Fampridine acid and clopyralid, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with clopyralid for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of clopyralid, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of clopyralid, and most preferably the acid of chlorine Fampridine is 3:2 ~ 15 with the mass ratio of clopyralid.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both clopyralids in weed killer herbicide, and preferred mass percentage composition is 10 ~ 75%.
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 comprises the water soluble salts such as sodium salt, sylvite, ammonium salt, isopropyl amine salt, methylamine salt, dimethylamine salt, alcohol salt, triethanolamine salt, triisopropanolamine salt.
Chlorine Fampridine acid of the present invention is with the binary built preparation of clopyralid, except the acid of chlorine Fampridine is with except clopyralid 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 aqua, wetting powder, water solube powder, water-soluble granule, water dispersible granules.
" % " of the present invention is mass percentage.
The application of mixed herbicide in uncultivated area, orchard, forest land, pasture, lawn and wheat paddock weeding of chloride Fampridine acid of the present invention and clopyralid, has remarkable result preventing and kill off the application in uncultivated area, orchard, forest land, pasture, lawn and wheat paddock in various broad leaved weed.
Compared to the prior art, beneficial effect of the present invention:
Mixed herbicide of the present invention, has instant effect, herbicide spectrum width, and the advantages such as the lasting period is long, weeding is thorough, it is low to remain, low toxicity, safety and environmental protection are the uncultivated area of high-quality, orchard, forest land, pasture and lawn chemical weed killer herbicide.
