Abstract
The invention discloses a mixed herbicide containing picloram and clethodim, and belongs to the technical field of pesticides. The herbicide is prepared from picloram and clethodim 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, wheat paddocks and oilseed rape fields, and is a high-quality chemical herbicide for bare places, orchards, forest lands, wheat paddocks and oilseed rape 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 clethodim.This herbicidal composition can be applicable to uncultivated area, orchard, forest land and Rapeseed 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.
Clethodim (clethodim), chemical name: (E)-2-[1-(3-chloroallyloxyamino imino group) propyl group]-5-[2-(ethylmercapto group) propyl group]-3-hydroxy cyclohexylphenyl-2-ketenes, belongs to cyclohexene type herbicides.Clethodim is the inner sucting conduction type cauline leaf inorganic agent that a kind of selectivity is very strong, can be absorbed by grassy weed cauline leaf, and reach top and joint meristematic tissue, by suppressing the biosynthesis of branched chain fatty acid and flavonoids, cell division is destroyed, thus by growing point and the necrosis of internode meristematic tissue, reduced growth, by withered in medicine plant 2-3 week.Resistance of rainwater washing against, can prevent and kill off annual and perennial grassy weed, to broad leaved plant safety.
Because current chlorine Fampridine acid residue problem is serious, usage amount and using method are strictly limited in a lot of countries and regions.In order to while minimizing herbicide carryover, guarantee the herbicidal effect of medicament, using being made into mixture after the acid of chlorine Fampridine and clethodim two kinds of suitable decrements of weed killer herbicide, so both expanding herbicide spectrum, 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 clethodim.
Another object of the present invention is to provide the application of this weed killer herbicide in uncultivated area, orchard, forest land, wheat paddock and rape field weeding.
The mixed herbicide of a kind of chloride Fampridine acid and clethodim, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with clethodim for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of clethodim, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of clethodim, and preferred chlorine Fampridine acid is 1:0.25 ~ 4 with the mass ratio of clethodim.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both clethodims 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 clethodim, except the acid of chlorine Fampridine is with except clethodim 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, wetting powder, water dispersible granules, microemulsion, soluble liquid.
" % " of the present invention is mass percentage.
The application of mixed herbicide in uncultivated area, orchard, forest land, wheat paddock and rape field weeding of chloride Fampridine acid of the present invention and clethodim, has remarkable result preventing and kill off the application in uncultivated area, orchard, forest land, wheat paddock and Rapeseed 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, wheat paddock and Rapeseed Field chemical herbicide.
