Abstract
The invention discloses a mixed herbicide containing picloram and flazasulfuron, and belongs to the technical field of pesticides. The herbicide is prepared from picloram and flazasulfuron in a mass ratio of (0.1-80): (0.1-80) as main effective ingredients. The mixed herbicide has the advantages of quick response, wide herbicide controlling spectrum, long duration, complete weed control, low residue, low toxicity, safety, environmental friendliness and the like when applied to weeding of bare places, orchards, forest lands, pastures, lawns and corn fields, and is a high-quality chemical herbicide for bare places, orchards, forest lands, 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 flazasulfuron.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.
Flazasulfuron (flazasulfuron), chemical name 1-(4,6-dimethoxypyridin-2-base)-3-(3-trifluoromethyl-2-pyridine sulfonyl sulfonyl) urea, be the sulfonylurea herbicide being originated in the exploitation of industry chemical company by Japanese stone, acetolactate synthestase (ALS) inhibitor.The main reaction suppressing the predecessor acetolactate synthestase producing side chain amino acid, leucine, isoleucine and valine.This medicament broad weed-killing spectrum, annual broad-leaved and grassy weed in Weeds in Turf that can not only be fabulous, and perennial broadleaf weed and sedge weed can also be prevented and kill off, as lady's-grass, barnyard grass, eleusine indica, annual bluegrass, amur foxtail, green foxtail, the rhizome of nutgrass flatsedge, kyllinga brevifolia, cyperus iria, difformed galingale herb, alternanthera philoxeroides, Horseweed Herb, white clover, it is recklessly appropriate, Tufted Cerastium, creeping oxalis, hairy tare, pale reddish brown order place, clover, pale persicaria, sheep hoof, class humid euphorbia, greater plantain, argy wormwood, sweet vernal grass, green amaranth, shepherd's purse, chickweed etc., to short leaf kyllinga brevifolia, lady's-grass and rhizome of nutgrass flatsedge preventive effect splendid.Generally, process after weeds stop growing immediately, absorbs the leaf chlorisis newly sent afterwards for 4-5 days, then gradually necrosis and spread to whole plant 20-30 days weeds thoroughly withered.This medicament absorbs by weeds cauline leaf, and can suppress suppressing weed seed germination in soil again, the control time is longer, and the lasting period is about more than 40 days in spring and summer, and autumn and winter is more than 120 days.
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 flazasulfuron 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 flazasulfuron.
Another object of the present invention is to provide the application of this weed killer herbicide in uncultivated area, orchard, forest land, pasture and Kill weeds.
The mixed herbicide of a kind of chloride Fampridine acid and flazasulfuron, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with flazasulfuron for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of flazasulfuron, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of flazasulfuron, and most preferably the acid of chlorine Fampridine is 6:5 ~ 64 with the mass ratio of flazasulfuron.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both flazasulfurons 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 flazasulfuron, except the acid of chlorine Fampridine is with except flazasulfuron 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 aqueous suspension agent, oil-suspending agent, water dispersible granules, wetting powder.
" % " 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.
