Abstract
The invention discloses a mixed herbicide containing picloram and clodinafop-propargyl, and belongs to the technical field of pesticides. The herbicide is prepared from picloram and clodinafop-propargyl 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 wheat paddocks, bare places, orchards, forest lands, pastures and lawns, and is a high-quality chemical herbicide for wheat paddocks, bare places, orchards, forest lands, pastures and lawns.
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 clodinafop-propargyl.This herbicidal composition can be applicable to wheat paddock, uncultivated area, orchard, forest land, pasture and lawn 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.
Clodinafop-propargyl (Clodinafop-propargyl), have another name called wheat pole, chemical name: (R)-2-[4-(the chloro-3-of 5-fluoro-2-pyridine oxygen base) phenoxy group] propionic acid propynyl ester, belong to fragrant phenoxy phenoxy propionic acid weed killer herbicide, effectively can suppress the biosynthesis of class ester, for the auxiliary quick A hydroxylase inhibitors of acetyl, it is cauline leaf inorganic agent after selectivity inner sucting conduction type seedling.Medicament conducts meristematic tissue by plant leaf blade, leaf sheath after absorbing, and suppresses acetyl-CoA carboxylase, thus suppresses fatty acid biological synthesis, finally causes weeds dead.Resistance makes the metabolite resolving into non-activity in object.This product is degraded to free acid phenyl very soon in soil and pyridine moiety enters soil.
In addition, clodinafop-propargyl in use must be mixed with safener, wherein clodinafop-propargyl and safener-cloquintocetmexyl or cloquitocet_mexyl etc. mix with 4:1 and support the use, be applied to wheat paddock weeding, the grassy weeds such as wheat vole tail amur foxtail, tall oat grass, perennial ryegrass, rough stalked blue grass, green foxtail can be prevented and treated.But clodinafop-propargyl is invalid to broad leaved weed, herbicidal spectrum is narrow, makes it be restricted in use.
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 clodinafop-propargyl 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 clodinafop-propargyl.
Another object of the present invention is to provide the application of this weed killer herbicide in wheat paddock, uncultivated area, orchard, forest land, pasture and lawn postemergence weed control.
The mixed herbicide of a kind of chloride Fampridine acid and clodinafop-propargyl, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with clodinafop-propargyl for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of clodinafop-propargyl, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of clodinafop-propargyl, and most preferably the acid of chlorine Fampridine is 1:0.5 ~ 4 with the mass ratio of clodinafop-propargyl.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both clodinafop-propargyls 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 clodinafop-propargyl, except the acid of chlorine Fampridine is with except clodinafop-propargyl 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, aqueous emulsion, suspending agent, water dispersible granules, water solube powder, microemulsion, soluble liquid, wetting powder.
" % " of the present invention is mass percentage.
The application of mixed herbicide in wheat paddock, uncultivated area, orchard, forest land, pasture and Kill weeds of chloride Fampridine acid of the present invention and clodinafop-propargyl, has remarkable result preventing and kill off the application in wheat paddock, uncultivated area, orchard, forest land, pasture and lawn 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 wheat paddock of high-quality, uncultivated area, orchard, forest land, pasture and lawn chemical weed killer herbicide.
