Abstract
The invention discloses a mixing herbicide containing aminopyralid and trifloxysulfuron sodium, which belongs to the pesticide technical field. The herbicide takes aminopyralid and trifloxysulfuron sodium as main effective components, wherein mass ratio of aminopyralid to trifloxysulfuron sodium is 0.1-80: 0.1-80. The mixing herbicide can be used in uncultivated areas, orchards, woodlands, pastures, lawns and corn fields for weeding, can effectively control the emerged weeds and unearthed weeds, has the advantages of fast effectiveness, wide weed control spectrum, long persistent period, complete weeding, low residues, low toxicity, safety and environmental protection, and is the high-quality chemical herbicide for uncultivated areas, orchards, woodlands, pastures, lawns and corn 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 trifloxysulfuron sodium.This herbicidal composition can be applicable to uncultivated area, orchard, forest land, pasture, lawn and corn field 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.
Trifloxysulfuron sodium (trifloxysulfuron sodium), chemical name: N-[(4,6-dimethoxy-2-pyrimidine radicals) carbamyl]-3-(2,2,2-trifluoro ethoxy)-2-pyridine sulfonamide sodium, trifloxysulfuron sodium is in sulfonylurea herbicide, can be absorbed by the root of weeds, stem, leaf after dispenser, can conduct downwards and upwards in plant corpus, by suppressing the activity of acetolactate synthestase (ALS), thus affect the biosynthesis of branched-chain amino acid (as: leucine, isoleucine, valine etc.).Show as growing point necrosis, vein chlorosis after hazard of plant, plant growth is subject to serious suppression, dwarfing, and final complete stool is withered.Trifloxysulfuron sodium to the selectivity of weeds and crop mainly due to the difference of katabolism.It can be non-activity material by rapid metabolization in cotton and sugarcane body, thus crop plant is escaped injury.
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 trifloxysulfuron sodium 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 trifloxysulfuron sodium.
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 cornfield weeding.
The mixed herbicide of a kind of chloride Fampridine acid and trifloxysulfuron sodium, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with trifloxysulfuron sodium for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of trifloxysulfuron sodium, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of trifloxysulfuron sodium, and most preferably the acid of chlorine Fampridine is 0.3 ~ 29:1 with the mass ratio of trifloxysulfuron sodium.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both trifloxysulfuron sodiums in weed killer herbicide, and preferred mass percentage composition is 10 ~ 75%.
Mixed herbicide of the present invention, wherein the acid of chlorine Fampridine exists 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 trifloxysulfuron sodium, except the acid of chlorine Fampridine is with except trifloxysulfuron sodium 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, water solube powder, aqueous suspension agent, oil-suspending agent, water dispersible granules, wetting powder, water-soluble granule.
" % " of the present invention is mass percentage.
The application of mixed herbicide in uncultivated area, orchard, forest land, pasture, lawn and cornfield weeding of chloride Fampridine acid of the present invention and flazasulfuron, has remarkable result preventing and kill off the application in uncultivated area, orchard, forest land, pasture, lawn and corn field 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, lawn and Chemical Weeding in Maize Field agent.
