Abstract
The invention discloses a mixed herbicide containing aminopyralid and cyhalofop-butyl, belonging to the technical field of pesticides. The herbicide takes aminopyralid and cyhalofop-butyl as main active ingredients, wherein the mass ratio of aminopyralid to cyhalofop-butyl is (0.1-80) to (0.1-80). The mixed herbicide has the advantages of quickness in effect taking, wide weeding spectrum, long lasting period, thoroughness in weeding, low residues, low toxicity, safety, environment friendliness, and the like when being applied to post-emergence weeding on non-cultivated lands and forest lands and in orchards, wheat fields and rape fields, and is a high-quality chemical herbicide applied to the non-cultivated lands, orchards, forest lands, wheat fields and rice 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 cyhalofop-butyl.This herbicidal composition can be applicable to uncultivated area, orchard, forest land, wheat paddock 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.
Cyhalofop-butyl (cyhalofop-butyl), virtue phenoxy phenoxy propionic acid weed killer herbicide, chemical name: (R)-2-[4 (4-cyano group-2-fluorophenoxy) phenoxy group]-butyl propionate is a kind of selectivity inner sucting conduction type cauline leaf process weed killer herbicide.As cauline leaf process, can be the stem of plant, leaf absorbs, be transmitted to growing point and meristematic tissue, by hindering the fatty acid synthesis of weeds to the suppression of acetyl-CoA carboxylase, suppressing weed growth, stop growing in several days by medicine weeds, later withered gradually.This medicine, to rice safety, mainly prevents and kill off barnyard grass, the grassy weeds such as moleplant seed, to sedge weed and broad leaved weed invalid.
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, be made into mixture after selecting the acid of chlorine Fampridine and cyhalofop-butyl two kinds of suitable decrements of weed killer herbicide and use, 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 cyhalofop-butyl.
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 agent for removing grass in paddy field.
The mixed herbicide of a kind of chloride Fampridine acid and cyhalofop-butyl, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with cyhalofop-butyl for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of cyhalofop-butyl, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of cyhalofop-butyl, and most preferably the acid of chlorine Fampridine is 1:0.5 ~ 4 with the mass ratio of cyhalofop-butyl.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both cyhalofop-butyls 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 cyhalofop-butyl, except the acid of chlorine Fampridine is with except cyhalofop-butyl 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, water dispersible granules, wetting powder, microemulsion, soluble liquid.
" % " of the present invention is mass percentage.
The application of mixed herbicide in uncultivated area, orchard, forest land, wheat paddock and agent for removing grass in paddy field of chloride Fampridine acid of the present invention and cyhalofop-butyl, has remarkable result preventing and kill off the application in uncultivated area, orchard, forest land, wheat paddock and paddy field in various broad leaved weed and part grassy 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 paddy field chemical herbicide.
