I-L-glufosinate-ammonium iyinhlanganisela entsha ye-tripeptide ehlukanisiwe kumhluzi wokuvutshelwa we-Streptomyces hygroscopicus yi-Bayer. Le nhlanganisela yakhiwe ama-molecule amabili e-L-alanine kanye nokwakheka okungaziwa kwe-amino acid futhi inomsebenzi wokubulala amagciwane. I-L-glufosinate-ammonium ingeyeqembu lama-phosphonic acid herbicides futhi yabelana ngendlela yayo yokusebenza ne-glufosinate-ammonium.

Ngokusho kocwaningo lwakamuva, ukusetshenziswa kakhulu kwe-glyphosate, i-herbicide ethengiswa kakhulu, kuholele ekuthuthukisweni kokumelana nokhula olufana ne-goosegrass, i-flyweed encane, ne-bindweed. I-International Cancer Research Institute ifake kuhlu i-glyphosate njengengaba yi-carcinogen yomuntu kusukela ngo-2015, futhi izifundo zokuphakela izilwane ezingapheli zibonise ukuthi zingandisa izigameko zesibindi nezinso zezinso.

Lezi zindaba ziholele ekutheni amazwe amaningana, okuhlanganisa iFrance neJalimane, avimbe i-glyphosate, okubangele ukwanda kokusetshenziswa kwezibulala-khula ezingakhethi njenge-glufosinate-ammonium. Ngaphezu kwalokho, ukuthengiswa kwe-glufosinate-ammonium kufinyelele ku-$1.050 billion ngo-2020, okuyenza ibe isibulala-zinambuzane esingakhethi esikhula ngokushesha emakethe.

I-L-glufosinate-ammonium ibonakale iphumelela kakhulu kunozakwabo wendabuko, inamandla angaphezu kwezikhathi ezimbili. Ngaphezu kwalokho, ukusetshenziswa kwe-L-glufosinate-ammonium kunciphisa inani lesicelo ngo-50%, ngaleyo ndlela kunciphisa umthelela wokulima emapulazini emthwalweni wemvelo.

Umsebenzi wokubulala ukhula we-herbicide usebenza esitshalweni se-glutamine synthetase ukuvimbela ukuhlanganiswa kwe-L-glutamine, okuholela ekugcineni ekuqongeleleni kwe-cytotoxic ammonium Ion, ukuphazamiseka kwe-ammonium metabolism, ukushoda kwe-amino acid, ukuhlakazeka kwe-chlorophyll, ukuvimbela i-photosynthesis, futhi ekugcineni nokufa kokhula.

Sengiphetha, i-L-glufosinate-ammonium herbicide ifakazele ukuthi iyindlela ephumelela kakhulu ye-glyphosate, ebibhekene nezinkinga eziningi zokulawula ngenxa yezakhiwo zayo ezingaba yi-carcinogenic. Ukwamukelwa kwayo kunganciphisa kakhulu inani lesicelo kanye nomthelela olandelayo endaweni ezungezile kuyilapho kusahlinzeka ngokulawula ukhula okuqinile.
