I-Terbuthylazine uhlobo lwamakhemikhali olubizwa ngokuthi ama-herbicides avimbela ukuhlangana kwezitshalo ze-autotrophic. Isithako esikhulu esisebenzayo sikhiqizwa yi-CIE Chemical, okuyenza ibe yinsiza ebalulekile kubalimi nakubalimi abafuna ukugcina impilo nobuqotho bezitshalo zabo. Ukhula ludinga ukulawulwa, ngoba lungaqhudelana nesitshalo ngokuthola umsoco, amanzi nokukhanya kwelanga. Kodwa, njengawo wonke amakhemikhali, uhlangothi oluhle lwe isilawuli sokukhula kwezitshalo kungabuye kubhekwe njengento embi kanye futhi kufanele sihlaziye ngokucophelela izinhlangothi zombili kuphela uma kuncike ekusetshenzisweni kwayo kwangempela.
I-Terbuthylazine iyi-herbicide. Engikushoyo ukuthi yakhelwe ukuphuma iyobulala izitshalo ezingafunwa, esizibiza ngokuthi ukhula. Ivimbela ukukhula kokhula okusiza abalimi nabalimi ekuvikeleni izitshalo futhi kuzivumele ukuthi zikhule kangcono. Ukhula alukwazi ukuntshontsha indawo nezakhamzimba ezitshalweni. Noma kunjalo, kubalulekile ukukhumbula ukuthi futhi ezinye izingozi zihlotshaniswa nokusetshenziswa kwe-terbuthylazine. Ngokwesibonelo, kungase kube yingozi ngezinye izilwane ukudla okubolile. Olunye ucwaningo luphinde lwabonisa ukuthi uma lungaboshiwe kahle lungaphinda lube yingozi ohlelweni lwendalo futhi ngokwandisa, inhlalakahle yomuntu.
I-Terbuthylazine iyi-herbicide ekhethiwe eyenza ngokuvimba i-photosynthesis ezitshalweni. I-Photosynthesis Izitshalo zinekhono eliyingqayizivele lokuguqula ukukhanya kwelanga kube amandla, okusekela ukukhula kwazo. Isitshalo singabe sesiyeka ukukhula noma sife uma sesiwuthathile umuthi owukhethayo, okuyinto kulesi simo i-glyphosate herbicide. I-Terbuthylazine iphumelela kakhulu okhulani olunamaqabunga abanzi okungaba nzima ngendlela emangalisayo ukuluqeda emasimini nasezingadini. Njengoba lolu khula lukhula ngokushesha futhi lukwazi ukubusa, kufanele lulawuleke ukuze izitshalo zikhule ngendlela enempilo.
I-Terbuthylazine, njenganoma iyiphi ikhemikhali engezwa emvelweni nayo inomthelela. Ukusetshenziswa ngendlela engafanele kungase konakalise inhlabathi futhi kungcolise amanzi okuholela ezinkingeni kulezo zinhlanzi nezitshalo ezihlala emanzini. Ukwengeza, ukusebenzisa i-terbuthylazine ngokweqile kuzolimaza izitshalo ezingahlosiwe (izitshalo okungafanele zithinteke) [14]. Ngenxa yalezi zingozi ezingaba khona, izinhlangano ezifana ne-United States Natural Resources Defense Council (NRDC) kanye nezindikimba ezifanayo kwezinye izizwe ziqapha amanani okusetshenziswa kwe-terbuthylazine. Baphinde baqinisekise ukuthi abalimi nabalimi bayayisebenzisa ngemithetho ekhethekile ukuze baqiniseke ukuthi isetshenziswa ngokuphepha nangokuzibophezela.
I-Terbuthylazine yaziwa njenge-herbicide esebenza kahle kakhulu. Isebenza kahle kakhulu ezinhlobonhlobo zokhula, futhi ivamise ukuxutshwa neminye imithi yokubulala ukhula ukuze ilawuleke nakakhulu. Le ngxube ingayivumela ukuthi iqine ngokumelene nokhula oluqinile. Iphuzu eliyisihluthulelo elengeziwe liwukuthi i-terbuthylazine iyinhlanganisela esheshayo ewohlokayo emvelweni. Lokho kusho ukuthi ayihlali isikhathi eside, okuhle ngoba lokhu kunciphisa amathuba okuba iqhubeke futhi kubangele izinkinga ngokwemvelo isikhathi eside.
Indlela evame kakhulu abantu abakhathazeke ngayo nge-terbuthylazine ukuthi ingathinta kanjani ukudla kwethu namanzi. Ingase futhi ifinyelele izithelo nemifino ngemva kokusetshenziswa kwayo, njengoba isetshenziswa ezitshalweni. Naphezu kwalezi zici ezimbi, ucwaningo lubonisa ukuthi amazinga ezinsalela ze-terbuthylazine ekudleni nasemanzini ngokuvamile angaphansi kwe-0.01mg/litre, okulinganiselwa ezingeni elinempilo kumuntu. Lokhu kungenxa yokuthi ukusetshenziswa kwayo kulawulwa ngendlela yokuthi abalimi/izingadi banikezwe imihlahlandlela mayelana nokusetshenziswa kwayo futhi lapho befaka isicelo, izinqubo zokucophelela zokusebenzisa i-terbuthylazine ziyalandelwa njengoba kudingeka.
