Abstract
The invention discloses a mixed herbicide containing aminopyralid and quinclorac, which belongs to the technical field of pesticide. The herbicide uses aminopyralid and quinclorac as main effective components, wherein the mass ratio of aminopyralid to quinclorac is 0.1-80: 0.1-80. The mixed herbicide provided by the invention is applied to non-cultivated land, orchards, woodland, paddy fields and wheat paddocks for post-emergence weeding and has the advantages of a wide weed control spectrum, fast action, high efficiency, low toxicity, safety, environment friendliness and the like.
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 dichloro quinolinic acid.This herbicidal composition can be applicable to uncultivated area, orchard, forest land, paddy field 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.
Dichloro quinolinic acid (quinclorac), the chloro-8-Quinoline Carboxylic Acid of chemical name: 3,7-bis-is Novel rice field herbicidal after seedling before the bud of BASF AG's exploitation, and this medical instrument has that consumption is few, the longevity of residure long, to barnyard grass special efficacy, use the advantages such as optimum period is wide.Dichloro quinolinic acid is a kind of hormone-type quinoline carboxylic acid weed killer herbicide, action target is the synthetic hormone in plant corpus, the activity of the enzyme regulated by interference plant hormone, make biology growing, metabolism can not normally carry out, occur leaf diminish, distortion, color burn, biomass reduce, severe patient is withered downright bad, until whole strain is dead and reach the object of weeding.Dichloro quinolinic acid is used for direct seading rice or transplanting rice field prevents the weeds such as barnyard grass, is better than other weed killer herbicides to preventing and kill off of above the average age for marriage barnyard grass.
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 dichloro quinolinic acid 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 dichloro quinolinic acid.
Another object of the present invention is to provide the application of this weed killer herbicide in uncultivated area, orchard, forest land, paddy field and wheat paddock weeding.
The mixed herbicide of a kind of chloride Fampridine acid and dichloro quinolinic acid, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with dichloro quinolinic acid for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of dichloro quinolinic acid, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of dichloro quinolinic acid, and most preferably the acid of chlorine Fampridine is 1:0.5 ~ 1.5 with the mass ratio of dichloro quinolinic acid.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both dichloro quinolinic acids in weed killer herbicide, and preferred mass percentage composition is 10 ~ 75%.
Mixed herbicide of the present invention, wherein said chlorine Fampridine acid 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; Described dichloro quinolinic acid exists with the form of acid or water soluble salt, and the water soluble salt of described dichloro quinolinic acid comprises sodium salt, sylvite, ammonia salt.
Chlorine Fampridine acid of the present invention is with the binary built preparation of dichloro quinolinic acid, except the acid of chlorine Fampridine is with except dichloro quinolinic acid 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 aqua, suspending agent, soluble liquid, wetting powder, water dispersible granules, soluble granula.
" % " of the present invention is mass percentage.
The application of mixed herbicide in uncultivated area, orchard, forest land, paddy field and wheat paddock weeding of chloride Fampridine acid of the present invention and dichloro quinolinic acid, has remarkable result preventing and kill off the application in uncultivated area, orchard, forest land, paddy field 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, paddy field and wheat paddock chemical herbicide.
