Abstract
The invention discloses a mixed herbicide containing picloram and picloram, and belongs to the technical field of pesticides. The herbicide is prepared from picloram and picloram 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 wheat paddocks, and is a high-quality chemical herbicide for bare places, orchards, forest lands, pastures, lawns and wheat paddocks.
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 picloram.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.
Picloram (picloram), amino-3,5, the 6-trichloropyridine of chemical name: 4--2-carboxylic acid, its chemical formula is: C

2.Picloram is a kind of interior suction, selective herbicide, has plant growth regulation.Mainly act on metabolism of nucleic acid, and make chloroplast structure and other organelle developmental deformities, interferencing protein synthesizes, and acts on meristematic tissue activity etc., finally causes Plant death.Be mainly used in cornfield herbicidal, most of broad leaf crop is harmful to.But picloram is invalid to grassy weed, and, during crop rotation, the impact of residual picloram on broad leaf crop (beans, vegetables, cotton, tobacco etc.) be considered, therefore, use and be subject to a definite limitation.
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 picloram 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 picloram.
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 picloram, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with picloram for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of picloram, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of picloram, and most preferably the acid of chlorine Fampridine is 3:2 ~ 15 with the mass ratio of picloram.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both picloram 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 picloram all exist with the form of water soluble salt, and described water-soluble salt 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 picloram, except the active ingredients such as the acid of chlorine Fampridine and picloram, 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 picloram, 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, lawn and wheat paddock chemical herbicide.
