The herbicide is prepared by taking picloram and fenoxaprop-p-ethyl as main effective components, wherein the mass ratio of picloram to fenoxaprop-p-ethyl is (0.1-80): (0.1-80). The mixed herbicide disclosed by the invention is applied to post-emergence weeding in uncultivated areas, gardens, forest lands, wheat paddocks, corn fields and oilseed rape fields, has the advantages of high effect taking speed, wide herbicide control spectrum, long lasting period, weeding thoroughness, low residual quantity, low toxicity, safety, environment friendliness and the like, and is a high-quality chemical herbicide for the uncultivated areas, the gardens, the forest lands, the wheat paddocks, the corn fields and the oilseed rape 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 fenoxapropPethyl.This herbicidal composition can be applicable to wheat paddock, uncultivated area, orchard, forest land, wheat paddock, corn field and Rapeseed 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.
FenoxapropPethyl (fenoxaprop-ethyl), belong to heterocyclic oxy group phenoxy propionic acid class weed killer herbicide, have another name called prestige despot, galloping horse, chemical name: (R)-2-[4-(6-chloro-1,3-benzoxazole-2-oxygen base) phenoxy group] ethyl propionate, chemical structural formula:
FenoxapropPethyl is selectivity inner sucting conduction type herbicide after seedling, mainly by suppressing key enzyme one acetyl-CoA carboxylase of fatty acid synthesis, thus inhibits the synthesis of fatty acid.Medicament is by cauline leaf Assimilation and conductivity to the growing point of meristematic tissue and root, and effect rapidly, stops growing for after dispenser 2-3 days, 5-6 days lobus cardiacus chlorosis purpling looks, and make meristematic tissue browning look, blade is withered gradually, is the extremely strong cauline leaf inorganic agent of selectivity.
In addition, this medicament changes rapidly benzene oxygen into from propionic acid after contact soil, and is decomposed into non-activity material further, thus to succession crop safety, resolves into the metabolite of non-activity and detoxify in drug resistance crop.Can be used for broad-leaved effect and prevent and kill off grassy weed.Can be used for wheat paddock after adding safener fenchlorazole and prevent and kill off grassy weed.
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 fenoxapropPethyl 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 fenoxapropPethyl.
Another object of the present invention is to provide the application of this weed killer herbicide in wheat paddock, uncultivated area, orchard, forest land, wheat paddock, corn field and rape field weeding.
The mixed herbicide of a kind of chloride Fampridine acid and fenoxapropPethyl, it is characterized in that this weed killer herbicide with chlorine Fampridine acid with fenoxapropPethyl for principle active component, the acid of chlorine Fampridine is 0.1 ~ 80:0.1 ~ 80 with the mass ratio of fenoxapropPethyl, preferred chlorine Fampridine acid is 1 ~ 60:1 ~ 60 with the mass ratio of fenoxapropPethyl, and most preferably the acid of chlorine Fampridine is 0.25 ~ 6:1 with the mass ratio of fenoxapropPethyl.
In mixed herbicide, the acid of chlorine Fampridine is 1 ~ 85% with the mass percentage of both fenoxapropPethyls in weed killer herbicide, and preferred mass percentage composition is 10 ~ 75%.
