The herbicide uses aminopyralid and penoxsulam as main effective components, wherein the mass ratio of aminopyralid to penoxsulam is 0.1-80: 0.1-80. The mixed herbicide provided by the invention is applied to non-cultivated land, orchards, woodland, corn fields and paddy fields for post-emergence weeding, has the advantages of fast action, a wide weed control spectrum, long lasting time of efficiency, thorough weeding, low residue, low toxicity, safety, environment friendliness and the like, and is a high-quality chemical herbicide for non-cultivated land, orchards, woodland, corn fields and paddy 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 penoxsuam.This herbicidal composition can be applicable to uncultivated area, orchard, forest land, corn field and paddy 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.
Penoxsuam (penoxsulam) is triazolopyrimidine sulfonamide weed killer herbicide, works by suppressing acetolactate synthestase (ALS).Chemical name: 3-(2,2-difluoroethoxy)-N-(5,8-dimethoxy-[1,2,4] triazol [1,5-C] pyrimidine-2-base)-α, α, α-fluoroform phenyl-2-sulfonamide.Penoxsuam is inner sucting conduction type herbicide after seedling, through cauline leaf, young shoot and Root Absorption, conducts to meristematic tissue by xylem and phloem, suppresses plant strain growth, makes growing point chlorosis, and the rear 7 ~ 14d terminal bud of process reddens, necrosis, and within 2 ~ 4 weeks, plant is dead.Penoxsuam is rice field broad-spectrum herbicide, effectively can prevent and kill off barnyard grass and annual sedge weed and effective to numerous broad leaved weed.
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, selection can herbicide be composed different, be made into mixture and use after the chlorine Fampridine acid of pluses and minuses complementation and penoxsuam 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 penoxsuam.
Another object of the present invention is to provide the application of this weed killer herbicide in uncultivated area, orchard, forest land, corn field and agent for removing grass in paddy field.
The mixed herbicide of a kind of chloride Fampridine acid and penoxsuam, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with penoxsuam for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of penoxsuam, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of penoxsuam, and most preferably the acid of chlorine Fampridine is 1 ~ 19:1 with the mass ratio of penoxsuam.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both penoxsuams 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 penoxsuam, except the acid of chlorine Fampridine is with except penoxsuam 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, oil-suspending agent.
" % " of the present invention is mass percentage.
The application of mixed herbicide in uncultivated area, orchard, forest land, corn field and agent for removing grass in paddy field of chloride Fampridine acid of the present invention and penoxsuam, has remarkable result preventing and kill off the application in uncultivated area, orchard, forest land, corn field and paddy 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, corn field and paddy field chemical herbicide.
