Imo yokusebenza kunye nophuhliso lwe-Glyphossate

I-Glyphosate luhlobo lwe-pholocine ye-phobicine ye-phosbine kunye ne-ebroad spectrum egcumayo. I-Glyphossate ithatha ikakhulu ngokuthintela i-biosynthengis ye-Amino Amino Acid, ebizwa ngokuba yiBiosynthesis yePhenylalanine, tryptophan kunye ne-tyrosine nge-shikimic indlela yendlela. Ineziphumo ezizimeleyo kwi-5-I-Elolpyruvylshik-3-phosphate synthase (i-EPSP Synthase), enokuthi ikhuphe i-jospyruvate phakathi kwe-5-3-phosphate kunye ne-5-phosphate Ngale biosynthesis yokuphendula kwe-enzymatic, kukhokelela ekuqokeleleni i-shikimic acid kwiVivo. Ukongeza, i-glyphoste inokukucinezela ezinye iintlobo ze-enzymes yesityalo kunye nomsebenzi we-enzyme wemilo. Imetabolism ye-Glyphossate kwizityalo eziphakamileyo icotha kakhulu kwaye ivavanyiwe ukuba i-metabolte i-Amimoomethylphostic acid kunye ne-methyl amino acetic acid. Ngenxa yokusebenza okuphezulu, ukonakaliswa okucothayo, kunye netyhefu yezityalo eziphezulu kwizityalo, i-glyphosate ithathwa njengohlobo lwezinto ezilawula ukhula Kwaye isiphumo esihle sokuthobela, ngakumbi kunye nendawo enkulu yokulinywa kwezityalo ze-Glyphoste-genegenic, iye yaba lelona ntsholongwane isetyenziswe kakhulu.

Ngokutsho kovavanyo lwe-PMRA, i-glyphossate ayinawo i-genotocity kwaye inokwenzeka ukubangela umngcipheko womhlaza ebantwini. Akukho mngcipheko kwimpilo yabantu kulindeleke kuvavanyo lokutya (ukutya kunye namanzi) ezinxulunyaniswa nokusetyenziswa kwe-glyphosate; Landela imiyalelo yeleyibhile, kwaye akukho sidingo sokukhathazeka ngohlobo lokuhlala usebenzisa i-glyphosate okanye umngcipheko kubahlali. Akukho mngcipheko kwindalo esingqongileyo kulindeleke xa isetyenziswa ngokungqinelana neleyibhile ehlaziyiweyo, kodwa i-buffer ehlaziyiweyo iyafuneka ukunciphisa umngcipheko onokubakho wokutshiza kwiintlobo zezilwanyana ezingajongwayo (izityalo, i-aquatic, i-aquatic, i-aquatic, intlanzi kwindawo ekufutshane nendawo ephantsi).

Kuqikelelwa ukuba ukusetyenziswa kwe-Glyphossate ye-Glyphossate kuya kuba ngama-600,000 ~ 750,000 t ngo-2040,000 t ngo-2025, ebonisa ukukhula ngokukhawuleza.
