Imazamox imidazolinone yokutshabalalisa ukhula lokulawula iintlobo zamagqabi abanzi

Ingcaciso yeMveliso

I-Imazamox ligama eliqhelekileyo lesithako esisebenzayo se-ammonium ityuwa ye-imazamox (2--[4,5-dihydro-4-methyl-4- (1-methylethyl)-5- oxo-1H-imidazol-2-yl] -5- (methoxymetl) -3- pyridinecarboxylic acid.Sisichiza sokhula esijikelezayo kwisityalo sonke kwaye sithintela izityalo ekuveliseni i-enzyme eyimfuneko, i-acetolactate synthase (ALS), engafumanekiyo kwizilwanyana.Izityalo ezithintekayo ziyakuyeka ukukhula ngokukhawuleza emva konyango emva konyango. I-imazamox yenziwe zombini njenge-asidi kunye netyuwa ye-isopropylamine.Ukuthathwa kwemidazolinone ye-herbicides kuqala ngamahlamvu kunye neengcambu. ukukhula) ngexylem kunye ne-phloem apho inqanda i-acetohydroxyacid synthase [AHAS; ekwaziwa njenge-acetolactate synthase (ALS)], i-enzyme ebandakanyeka ekudityanisweni kwee-amino acid ezintathu ezibalulekileyo (valine, leucine, isoleucine). protein synthesiskunye nokukhula kweeseli.Ngaloo ndlela i-Imazamox iphazamisa i-protein synthesis kwaye iphazamisa ukukhula kweeseli kunye ne-DNA synthesis, ebangela ukuba isityalo sife ngokukhawuleza.Ukuba isetyenziswe njenge-post-emergence herbicide, i-imazamox kufuneka isetyenziswe kwizityalo ezikhulayo.Ingaphinda isetyenziswe ngexesha lokuhluthwa ukunqanda ukukhula kwakhona kwezityalo nakwizityalo ezikhulayo.

I-Imazamox isetyenziselwa ukutshabalalisa ukhula kumagqabi amaninzi antywilayo, asahlumayo, kunye namagqabi abanzi adadayo kunye nezityalo zasemanzini zemonocot ngaphakathi najikelezileyo emi kunye neendawo ezicothayo zamanzi.

I-Imazamox iya kushukuma kwimihlaba emininzi, edityaniswa nokuzingisa kwayo okuphakathi kungenza kube lula ukufikelela kwayo emanzini aphantsi.Ulwazi oluvela kuphononongo lwekamva lokusingqongileyo lubonisa ukuba i-imazamox akufuneki iqhubele kumanzi angekho nzulu.Nangona kunjalo, kufuneka iqhubeke emanzini kubunzulu obukhulu xa kukho imeko-bume ye-anaerobic kwaye apho ukuthotywa kwefotolytic kungeyonto.

I-Imazamox ayinayo ityhefu kwintlanzi yasemanzini ahlaziyekileyo kunye ne-estuarine kunye ne-invertebrates kwisiseko esibukhali.Idatha yetyhefu ebukhali kwaye engapheliyo ikwabonisa ukuba i-imazamox ayinabungozi kwizilwanyana ezanyisayo.
