I-imazamox imidazolinone herbicide yokulawula izinhlobo zamaqabunga abanzi

Incazelo yomkhiqizo

I-Imazamox igama elivamile lesithako esisebenzayo i-ammonium usawoti we-imazamox (2--[4,5-dihydro-4-methyl-4-(1-methylethyl)-5- oxo-1H-imidazol-2-yl]-5- (i-methoxymethl)-3- pyridinecarboxylic acid.Iwumuthi wokubulala ukhula wesistimu ohamba phakathi kwezicubu zezitshalo futhi uvimbela izitshalo ekukhiqizeni i-enzyme edingekayo, i-acetolactate synthase (ALS), engatholakali ezilwaneni. Izitshalo ezithintekayo zizoyeka ukukhula ngokushesha ngemva kokwelashwa. I-Imazamox yenziwa kokubili njenge-asidi nanjenge-isopropylamine usawoti.Ukuthathwa kwemithi yokubulala ukhula imidazolinone ngokuyinhloko kusetshenziswa amahlamvu nezimpande. ukukhula) nge-xylem ne-phloem lapho ivimbela i-acetohydroxyacid synthase [AHAS; eyaziwa nangokuthi i-acetolactate synthase (ALS)], i-enzyme ehilelekile ekuhlanganiseni kwama-amino acid amathathu abalulekile (valine, leucine, isoleucine). Lawa ma-amino acid ayadingeka ukuze amaprotheni synthesiskanye nokukhula kwamangqamuzana.Ngakho-ke i-Imazamox iphazamisa ukuhlanganiswa kwamaprotheni futhi iphazamise ukukhula kweseli kanye nokuhlanganiswa kwe-DNA, okwenza isitshalo sife kancane.Uma isetshenziswa njenge-post-emergence herbicide, i-imazamox kufanele ifakwe ezitshalweni ezikhula ngokuzimisela.Ingasetshenziswa futhi ngesikhathi sokunciphisa ukuvimbela ukukhula kabusha kwezitshalo kanye nezimila ezikhulayo.

I-Imazamox ibulala ukhula ezitshalweni eziningi zasemanzini ezicwilisiwe, ezisafufusa, nezintantayo emanzini nasezindaweni ezizungezile ezimile nezihamba kancane.

I-Imazamox izohambahamba emihlabathini eminingi, okuhambisana nokuphikelela kwayo okusesilinganisweni kungenza kube lula ukufinyelela kwayo emanzini angaphansi.Ulwazi oluvela ocwaningweni lwesiphetho sezemvelo lubonisa ukuthi i-imazamox akufanele iqhubeke emanzini angashoni kakhulu.Kodwa-ke, kufanele iqhubeke emanzini ekujuleni okukhulu lapho indawo ye-anaerobic ikhona nalapho ukuwohloka kwezithombe kungeyona into.

I-Imazamox ayinabo ubuthi ezinhlanzini zasemanzini ahlanzekile nase-estuarine kanye nezilwane ezingenamgogodla lapho zichayeka kakhulu.Idatha yobuthi ebukhali futhi engapheli iphinda ikhombise ukuthi i-imazamox ayinabo ubuthi ezilwaneni ezincelisayo.
