Abstract
The invention discloses a mixed herbicide containing picloram and fenoxaprop-p-ethyl, belonging to the technical field of herbicides. 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 herbicide field, it is related to the acid of chlorine Fampridine and fenoxapropPethyl
Binary built agent.This herbicidal composition can be applicable to bare place, orchard, forest land, wheat paddock, corn field and Rapeseed Field after seedling
Weeding.
Background technology
Chlorine Fampridine acid (aminopyralid), chemical name: 4- amino -3,6- dichloropyridine -2- carboxylic acid, chlorine Fampridine
Acid is a kind of pyridines herbicide, is widely used in the control of weeds of mountain region, grassland, lawn, plantation and bare place.Can prevent and treat
Annual or perennial broadleaf weed.
FenoxapropPethyl (fenoxaprop-ethyl), belongs to heterocyclic oxy group phenoxy propionic acid class herbicide, also known as prestige despot,
Galloping horse, chemical name: (r) -2- [4- (6- chloro- 1,3- benzothiazole -2- epoxide) phenoxy group] ethyl propionate, chemical structural formula:
FenoxapropPethyl is selectivity inner sucting conduction type herbicide after seedling, mainly passes through to suppress the pass of fatty acid synthesis
Key enzyme one acetylcoenzyme a carboxylase, thus inhibit the synthesis of fatty acid.Medicament pass through stem and leaf Assimilation and conductivity to separate living tissue and
The growing point of root, effect is rapid, stops growing within 2-3 days after dispenser, and lobus cardiacus chlorosis becomes purple within 5-6 days, makes separate living tissue become brown,
Blade is gradually withered, is the extremely strong cauline leaf process agent of selectivity.
Additionally, this medicament is changed into rapidly benzene oxygen from propanoic acid after contact soil, and it is further broken into inactive material,
Thus to succession crop safety, resolve into inactive metabolite in drug resistance crop and detoxify.Can be used for broad-leaved effect anti-
Except 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, a lot of countries and regions be strictly limited usage amount and
Using method.In order to while reducing herbicide carryover it is ensured that the herbicidal effect of medicament, by the acid of chlorine Fampridine and smart oxazole dogstail
It is made into mixture after the suitable decrement of two kinds of herbicides of spirit to use, so both expands weed control spectrum, it also avoid succession crop is produced
The probability of residual hazard.
