Description
Technical field
The present invention relates to the herbicide in agriculture field, more particularly relates to the weeding of a kind of glyphosate and glufosinate-ammonium compounding
Agent composition.
Background technology
The herbicide used at present on forest land is based on the steriland herbicides such as glyphosate, Kirchhoff integral.But glyphosate is alone
It is little to some Weed-control effects and not ideal enough to broad leaved weed effect；Kirchhoff integral is contact killing type herbicide, can only kill plant
The aerial part of object, it is poor to some perennial weeds effects, and toxicity itself is very high, easily causes poisoning.
Glyphosate (glyphosate) is inner sucting conduction type wide spectrum steriland herbicide.Natural enemy and beneficial organism are relatively pacified
Entirely.Mainly by suppressing enolpyruvyl shikimene phosphate synthase in plant, so as to suppress shikimene to phenylalanine, junket
The conversion of propylhomoserin and tryptophan, the synthesis of protein is interfered causes Plant death.Glyphosate so that uptake and translocation is strong and
Famous, it can not only be transmitted under ground portion by cauline leaf, and can also be conducted between the different tillers of same plant, right
The underground organization destructive power of perennial deep root weeds is very strong, can reach the depth that general agricultural machinery is unable to reach.Glyphosate kills
Grass composes very wide, the plant effect of preventing and kill off to section more than 40, including unifacial leaf and dicotyledonous, annual and perennial, draft and filling
The plants such as wood.The better resistance of pulse family and some plants of Liliaceae to glyphosate.Glyphosate bury after quickly with the metal such as iron, aluminium
Ions binding and lose activity.
Glufosinate-ammonium (Glufosinate ammonium) belongs to organic phosphates herbicide, is glutamine synthetase inhibitor, non-
Selective contact killing type herbicide, and second-biggest-in-the-world genetically modified crops herbicide-tolerant.Its effect is rapider than glyphosate, tool
There is broad weed-killing spectrum, degraded in soil is fast, toxicity is low, environmentally friendly, be that another performance is excellent after glyphosate
Good steriland herbicide kind, the country is only registered at present prevents and kill off for orchard, bare place weeds.With both at home and abroad to hundred grass
Withered disabling, representative of the glufosinate-ammonium as contact killing type herbicide, the market share will be increasing.Relatively approve both at home and abroad at present
Glufosinate-ammoniumaqua aqua auxiliary agent mainly include the compound such as AES, APG, alkyl, polyether.
It is bad to preventive effects such as sedge, perennial weeds and broadleaf weeds due to glyphosate is used alone,
And dosage is more.In order to prevent and kill off the weeds such as perennial weeds, broadleaf weed and sedge simultaneously, it is therefore desirable to
Glyphosate and other herbicides compounds are compounded according to certain ratio, herbicidal effect is improved, reduces the administration of herbicide
