Imazamox imidazolinone herbicide rau kev tswj cov kab dav dav
Khoom piav qhia
Imazamox yog lub npe nrov ntawm cov khoom xyaw nquag ammonium ntsev ntawm imazamox (2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5- oxo-1H-imidazol-2-yl]-5- (methoxymethl)-3- pyridinecarboxylic acid Nws yog ib qho tshuaj tua kab mob uas txav mus thoob plaws hauv cov ntaub so ntswg thiab tiv thaiv cov nroj tsuag los ntawm kev tsim cov enzyme tsim nyog, acetolactate synthase (ALS), uas tsis pom hauv cov tsiaj. Tab sis cov nroj tsuag tuag thiab decomposition yuav tshwm sim nyob rau hauv ob peb lub lis piam, Imazamox yog formulated ob qho tib si raws li ib tug acid thiab raws li ib tug isopropylamine ntsev, Uptake ntawm imidazolinone herbicides feem ntau yog los ntawm cov nplooj thiab cov hauv paus hniav. kev loj hlob) los ntawm xylem thiab phloem qhov twg nws inhibits acetohydroxyacid synthase [AHAS; tseem hu ua acetolactate synthase (ALS)], ib qho enzyme koom nrog hauv synthesis ntawm peb yam tseem ceeb amino acids (valine, leucine, isoleucine). protein synthesisthiab kev loj hlob ntawm tes.Imazamox yog li cuam tshuam cov protein synthesis thiab cuam tshuam nrog kev loj hlob ntawm tes thiab DNA synthesis, ua rau cov nroj tsuag maj mam tuag.Yog tias siv los ua tshuaj tua kab mob tom qab tshwm sim, imazamox yuav tsum tau siv rau cov nroj tsuag uas nquag loj hlob.Nws kuj tseem siv tau thaum lub sijhawm rub tawm los tiv thaiv cov nroj tsuag regrowth thiab ntawm cov nroj tsuag tshwm sim.
Imazamox yog herbicidally active nyob rau hauv ntau submerged, tshwm sim, thiab floating broadleaf thiab monocot dej nroj tsuag nyob rau hauv thiab ib ncig ntawm sawv thiab maj mam tsiv dej lub cev.
Imazamox yuav yog mobile nyob rau hauv ntau cov av, uas ua ke nrog nws nruab nrab persistence yuav pab tau nws mus txog rau hauv av.Cov ntaub ntawv los ntawm ib puag ncig txoj hmoo kev tshawb fawb qhia tias imazamox yuav tsum tsis txhob nyob twj ywm hauv cov dej ntiav.Txawm li cas los xij, nws yuav tsum nyob twj ywm hauv dej ntawm qhov tob dua thaum muaj ib puag ncig anaerobic thiab qhov twg photolytic degradation tsis yog qhov tseem ceeb.
Imazamox yog xyaum tsis muaj tshuaj lom rau cov dej tshiab thiab cov ntses estuarine thiab invertebrates ntawm qhov raug mob.Cov ntaub ntawv mob toxicity thiab mob ntev kuj qhia tau tias imazamox yog cov tshuaj tsis muaj tshuaj lom rau cov tsiaj.
