Imazamox ndi dzina lodziwika bwino lazomwe zimagwiritsidwa ntchito mchere wa ammonium mchere wa imazamox (2- [4,5-dihydro-4-methyl-4- (1-methylethyl) -5- oxo-1H-imidazol-2-yl] -5- (methoxymethl) -3- pyridinecarboxylic acid.Ndi mankhwala a herbicide omwe amayenda mumthupi lonse la zomera ndikulepheretsa zomera kupanga enzyme yofunikira, acetolactate synthase (ALS), yomwe sipezeka mwa nyama. Imazamox imapangidwa ngati asidi komanso mchere wa isopropylamine. Kumwa kwa imidazolinone herbicides kumachitika makamaka m'masamba ndi mizu yake. kukula) ndi xylem ndi phloem kumene imalepheretsa acetohydroxyacid synthase [AHAS; yotchedwanso acetolactate synthase (ALS)], puloteni yomwe imakhudzidwa ndi kuphatikizika kwa ma amino acid atatu (valine, leucine, isoleucine). kaphatikizidwe ka mapulotenindi kukula kwa cell.Imazamox imasokoneza kaphatikizidwe ka mapuloteni ndikusokoneza kukula kwa maselo ndi kaphatikizidwe ka DNA, zomwe zimapangitsa kuti mbewuyo kufa pang'onopang'ono.Ngati imagwiritsidwa ntchito ngati mankhwala ophera udzu, imazamox iyenera kugwiritsidwa ntchito pazomera zomwe zikukula mwachangu.Itha kugwiritsidwanso ntchito panthawi yochepetsera kuletsa kumeranso kwa zomera komanso zomera zomwe zatuluka.
Imazamox imagwiritsa ntchito herbicides pamitengo yambiri yomwe ili pansi pamadzi, yotuluka, komanso yoyandama komanso yoyandama pamitengo yamadzi yam'madzi m'malo ozungulira omwe atayima komanso omwe akuyenda pang'onopang'ono.
Imazamox idzakhala ikuyenda m'nthaka zambiri, zomwe kuphatikiza ndi kulimbikira kwake pang'onopang'ono zitha kupangitsa kuti madzi atsike pansi.Zambiri zochokera ku kafukufuku wachilengedwe zikuwonetsa kuti imazamox sayenera kupitilira pamadzi osaya.Komabe, iyenera kupitilirabe m'madzi akuya kwambiri pomwe malo a anaerobic alipo komanso pomwe kuwonongeka kwa photolytic sikuli chifukwa.
Imazamox ilibe poizoni ku nsomba zam'madzi am'madzi ndi estuarine komanso zamoyo zam'mimba zomwe zimawonekera pachimake.Zowopsa komanso zosakhalitsa za kawopsedwe zikuwonetsanso kuti imazamox sizowopsa kwa nyama zoyamwitsa.
