Imazamox imidazolinone herbicide no ka mālama ʻana i nā ʻano lau ākea
wehewehe huahana
ʻO Imazamox ka inoa maʻamau o ka paʻakai ammonium ikaika o imazamox (2- [4,5-dihydro-4-methyl-4-(1-methylethyl) -5- oxo-1H-imidazol-2-yl] -5- (methoxymethl)-3- pyridinecarboxylic acid He herbicide systemic e neʻe ana i loko o ka ʻiʻo o ka mea kanu a pale i nā mea kanu mai ka hana ʻana i kahi enzyme pono, acetolactate synthase (ALS), ʻaʻole i loaʻa i nā holoholona. , akā, e hiki mai ana ka make a me ka palaho o ka mea kanu i kekahi mau pule. Hoʻokumu ʻia ʻo Imazamox ma ke ʻano he waika a me ka paʻakai isopropylamine. ʻO ka lawe ʻana i nā herbicides imidazolinone ma o nā lau a me nā aʻa. ulu) e ka xylem a me ka phloem kahi e kaohi ai i ka acetohydroxyacid synthase [AHAS; i ʻike ʻia hoʻi ʻo acetolactate synthase (ALS)], he enzyme i komo i ka synthesis o ʻekolu amino acids pono (valine, leucine, isoleucine). Pono kēia mau amino acids no hoʻohui pūmuaa me ka ulu ʻana o ke kelepona.Hoʻopilikia ʻo Imazamox i ka synthesis protein a keʻakeʻa i ka ulu ʻana o ka cell a me ka synthesis DNA, e make mālie ai ka mea kanu.Inā hoʻohana ʻia ma ke ʻano he herbicide post-emergence, pono e hoʻopili ʻia ka imazamox i nā mea kanu e ulu ikaika nei.Hiki ke hoʻohana ʻia i ka wā huki e pale ai i ka ulu hou ʻana o nā mea kanu a ma luna o nā mea kanu e puka mai ana.
He lāʻau lapaʻau ʻo Imazamox ma nā lau lau ākea a me ka monocot i loko o nā kino wai e kū ana a me ka neʻe mālie.
E paʻa ʻo Imazamox i nā ʻāina he nui, i hui pū ʻia me kona hoʻomau haʻahaʻa hiki ke maʻalahi i kona hiki ʻana i ka wai lepo.Hōʻike ka ʻike mai nā haʻawina hopena kaiapuni ʻaʻole pono e hoʻomau ka imazamox i nā wai pāpaʻu.Eia nō naʻe, pono ia e hoʻomau i ka wai ma kahi hohonu loa i ka wā e noho ana kahi kaiapuni anaerobic a ma kahi o ka degradation photolytic ʻaʻole ia he kumu.
ʻAʻole ʻawaʻawa ʻo Imazamox i ka wai maʻemaʻe a me nā iʻa estuarine a me nā invertebrates ma ke kumu hoʻolaha.Hōʻike pū ka ʻikepili ʻona a me ka maʻi maʻi i ka imazamox he mea ʻona ʻole i nā mammals.
