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).
