Internal enolpyruvyl shikimene phosphate synthase, so that suppress shikimene to the conversion of phenylalanine, cruel propylhomoserin and tryptophan,
The synthesis of protein is interfered causes Plant death.Glyphosate is to be transmitted to plant parts after being absorbed by cauline leaf,
The plant of the section more than 40 such as unifacial leaf and dicotyledonous, annual and perennial, draft and shrub can be prevented and kill off, to part weeds sensitiveness
Difference.Glyphosate is combined and lost activity with the metal ion such as iron, aluminium quickly after burying, micro- to the seed and soil that are hidden in soil
Biology has no adverse effects, and because it is without selectivity, therefore is widely used in the ground weeding such as non-farmland, orchard, road, forestry, closely
Nian Laiqi applications are progressively excessive.Its structural formula is：
Haloxyfop-r-methyl also known as smart cover grass energy, the spirit of high-effective microorganism fluorine pyrrole second grass, haloxyfop-r-methyl, English common name
Haloxyfop-methyl, chemical name is：2- [4- (the chloro- 5- trifluoromethyls -2- pyridines epoxides of 3-) phenoxy group] propionic acid, its CA
Registration number：72619-32-0, molecular formula C16H13ClF3N3NO4, molecular weight 361.7；It is a kind of phenoxy carboxylic acid selective herbicidal
Agent, various grassy weeds are prevented and kill off for various broad leaf crop Tanakas, especially to the perennial stubbornness such as reed, cogongrass, Bermuda grass
Grassy weed has remarkable preventive effect.Effect stability under cryogenic conditions.Its structural formula is：
Azoles humulone is also known as gone out spirit, the careless ester of triazolone, carfentrazone, English common name carfentrazone-ethyl, chemistry soon
It is entitled：Ethyl -2- chloro- 3- the chloro- 5- of 2- [4- (difluoromethyl) -4,5- dihydro -3- methyl -5- oxygen -1H-1,2,4- triazoles -
1- yls] -4- fluorophenyls } ethyl propionate, its CA registration number：128639-02-1, molecular formula C15H14Cl2F3N3O3, molecular weight
412.2, it is a kind of triazolineone herbicide, it has good low temperature resistant and resistance of rainwater washing against effect, can suppress former porphin
Quinoline original oxidizing ferment causes the accumulation of poisonous intermediate, blade is dried up rapidly, dead, available for preventing and kill off broad leaved weed and nutgrass flatsedge.
Its structural formula is：
Chinese patent discloses some glyphosates, haloxyfop-r-methyl and azoles humulone and synthesized with other compound groups
Herbicide, for example：201510731448.5, a kind of Herbicidal combinations containing haloxyfop-r-methyl and glyphosate；
201510733638.0, a kind of Herbicidal combinations containing fluoroglycofen-ethyl；201510965112.5, a kind of oil uses tree peony field
Herbicidal methods；201310491567.9, the herbicidal composition of Glufosinate-ammoniumpesticideng, glyphosate and azoles humulone；201410556822.8,
A kind of weeding pharmaceutical composition and its preparation；Show glyphosate, haloxyfop-r-methyl and azoles humulone and they with it is other
Compound group into herbicide there is preferable herbicide effect and applied to agriculturally.
At present text is had no with the research and application of glyphosate, haloxyfop-r-methyl and azoles humulone this 3 kinds of mixture of herbicides
Offer open report.
Iron awn winnow basket, hill gooseberry, reed, Bermuda grass, Horseweed Herb, cogongrass, chinaroot greenbrier etc. are common in forest land and bare place
Weeds, glyphosate, haloxyfop-r-methyl and azoles humulone, which is used alone, can not prevent and kill off these grass simultaneously, moreover, in practical application
The weeding speed of middle exclusive use glyphosate and haloxyfop-r-methyl is slow, and easily by the shadow of the bad climates such as low temperature, rainfall
Ring and limit the performance of drug effect.
Different herbicide, which carries out compounding, can expand herbicide controlling spectrum, and use the different mixture of herbicides of the mode of action can be with
Show that synergistic effect, i.e. mixture are higher than the desired value of each component independent role in mixture to the inhibitory action of weed growth,
Make weeds be difficult to eliminate influence of the different herbicides to its metabolic pathway, and then delay the generation of Weed Resistance, be exploitation weeding
The target of agent complex preparation, is also to mitigate environmental pollution, reduces the effective means of herbicide residue.Through screening, by glyphosate or
Its salt, haloxyfop-r-methyl, azoles humulone compounding can realize above-mentioned advantage, and the herbicide combination product containing mentioned component also has herbicide
Fireballing feature, drug effect is difficult to be influenceed by bad climates such as low temperature, rainfalls, be iron awn winnow basket, hill gooseberry, reed, Bermuda grass,
The fine herbicide of the weeds chemical control such as Horseweed Herb, cogongrass, chinaroot greenbrier.
