Abstract
The invention discloses a mixed herbicide containing aminopyralid and quizalofop-p-ethyl, belonging to the technical field of pesticides. The herbicide takes aminopyralid and quizalofop-p-ethyl as main active ingredients, wherein the mass ratio of aminopyralid to quizalofop-p-ethyl 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, rape fields and wheat fields, and is a high-quality chemical herbicide applied to the non-cultivated lands, orchards, forest lands, rape fields and wheat 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 Quizalotop-ethyl.This herbicidal composition can be applicable to uncultivated area, orchard, forest land, Rapeseed 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.
Quizalotop-ethyl (quizalofop-p-ethyl), have another name called smart quizalofopethyl, chemical name: (R)-2-[4-(6-chloroquinoxalin-2-yloxy) phenoxy group] ethyl propionate, be a kind ofly novel there is optically active dry land cauline leaf inorganic agent, there is the advantages such as efficient, low toxicity, use safety.Between grassy weed and dicotyledonous crops, have the selectivity of height, absorbed by weeds cauline leaf, Bidirectional Conduction up and down in plant corpus, is accumulated in top and internode meristematic tissue, and T suppression cell fatty acid synthesizes, and makes weeds downright bad.Have good preventive effect to the grassy weed in broad leaf crop field, smart quizalofopethyl speed of action is fast, and efficacy stability, is not subject to the impact of the environmental conditions such as rainwater temperature and humidity.
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 Quizalotop-ethyl 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 Quizalotop-ethyl.
Another object of the present invention is to provide the application of this weed killer herbicide in uncultivated area, orchard, forest land, Rapeseed Field and wheat paddock weeding.
The mixed herbicide of a kind of chloride Fampridine acid and Quizalotop-ethyl, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with Quizalotop-ethyl for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of Quizalotop-ethyl, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of Quizalotop-ethyl, and most preferably the acid of chlorine Fampridine is 0.5 ~ 2:1 with the mass ratio of Quizalotop-ethyl.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both Quizalotop-ethyls 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 Quizalotop-ethyl, except the acid of chlorine Fampridine is with except Quizalotop-ethyl 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, Rapeseed Field and wheat paddock weeding of chloride Fampridine acid of the present invention and Quizalotop-ethyl, has remarkable result preventing and kill off the application in uncultivated area, orchard, forest land, Rapeseed Field and wheat paddock in various broad leaved weed and 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, Rapeseed Field and wheat paddock chemical herbicide.
