Abstract
The invention discloses a mixed herbicide containing aminopyralid and 2-methyl-4-chlorophenoxyacetic acid, which belongs to the technical field of pesticide. The herbicide uses aminopyralid and 2-methyl-4-chlorophenoxyacetic acid as main effective components, wherein the mass ratio of aminopyralid to 2-methyl-4-chlorophenoxyacetic acid is 0.1-80: 0.1-80. The mixed herbicide provided by the invention is applied to non-cultivated land, orchards, woodland, pasture, lawn, wheat paddocks and corn fields for weeding, has the advantages of fast action, a wide weed control spectrum, long lasting time of efficiency, thorough weeding, low residue, low toxicity, safety, environment friendliness and the like, and is a high-quality chemical herbicide for non-cultivated land, orchards, woodland, pasture, lawn, wheat paddocks and corn fields.
Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field, it is related to the binary of the acid of chlorine Fampridine and 2 first 4 chlorine
Built agent.This herbicidal composition can be applicable to bare place, orchard, forest land, pasture, lawn, wheat paddock and maize 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.
2 first 4 chlorine, chemical name: 2- methyl -4- tomatotone, is a kind of phytohormone of synthetic, have with
The similar physiological effect of auxin (iaa), can be used as plant growth regulating, is the conventional life being formed for callus induction
One kind of long element analog.2 first 4 chlorine mainly acts on dicotyledon, can prevent and kill off in the crop fields such as wheat, rice, Semen Maydiss, Caulis Sacchari sinensis
The broad leaved weeds such as Herba chenopodii, Herba Amaranthi tricoloriss and budding period grassy weed.Absorbability.Can enter in plant body from stem, leaf, degraded is slow, therefore can
Accumulation finite concentration, thus disturbing plant hormone in vivo to balance, destroys nucleic acid and protein metabolism, promotes or suppresses some organs
Growth, makes weeds stem and leaf distort, and stem foot is thicker, swollen split.
The residue problem of chlorine Fampridine acid at present is serious, has been strictly limited usage amount and use in a lot of countries and regions
Method.In order to while reducing herbicide carryover it is ensured that the herbicidal effect of medicament, the present invention select can weed control spectrum different, excellent lack
It is made into mixture use after the complementary chlorine Fampridine acid of point and the suitable decrement of 2 first, two kinds of herbicides of 4 chlorine, so both expanded herbicide
Spectrum, hence it is evident that improve herbicidal effect, it also avoid succession crop is produced with the probability of residual hazard.
Content of the invention
It is an object of the invention to provide the mixed herbicide of a kind of chloride Fampridine acid and 2 first 4 chlorine.
