Imazamox imidazolinone herbicide yekudzora mhando dzemashizha makuru

Chigadzirwa tsananguro

Imazamox ndiro zita rinowanzozivikanwa rechishandiso chinoshandiswa ammonium munyu we imazamox (2- [4,5-dihydro-4-methyl-4- (1-methylethyl)-5- oxo-1H-imidazol-2-yl]-5- (methoxymethl) -3- pyridinecarboxylic acid.Mushonga wesora unofamba mumiti yese uye unodzivirira kuti zvirimwa zvisaburitse enzyme inodiwa, acetolactate synthase (ALS), isingawanikwe mumhuka. Imazamox inogadzirwa seasidhi uye isopropylamine munyu.Kutorwa kwemidazolinone kunoitwa kuburikidza nemashizha nemidzi.Mushonga wesora unozoendeswa kumeristematic tissue kukura) nexylem uye phloem apo inodzivirira acetohydroxyacid synthase [AHAS; inozivikanwawo seacetolactate synthase (ALS)], enzyme inobatanidzwa mukuumbwa kwemaamino acid matatu anokosha (valine, leucine, isoleucine). Aya amino acids anodiwa protein synthesisuye kukura kwesero.Imazamox nokudaro inokanganisa kugadzirwa kweprotein uye inokanganisa kukura kwesero uye DNA synthesis, zvichiita kuti muti wacho ufe zvishoma nezvishoma.Kana ikashandiswa semushonga wesora wepashure, imazamox inofanira kuiswa kune zvirimwa zviri kushingaira kukura.Inogona zvakare kushandiswa panguva yekudonha kudzivirira kukura kwechirimwa uye pane zvinomera zvinomera.

Imazamox inouraya sora pamashizha akawanda akanyura, ari kubuda, uye akayangarara mashizha makuru uye monocot yemumvura mukati nekupoterera mitumbi yemvura yakamira uye inononoka kufamba.

Imazamox ichave inofamba muvhu rakawanda, izvo zvakabatanidzwa nekushingirira kwayo zvine mwero zvinogona kuita kuti mvura isvike pasi.Ruzivo kubva kuongororo yezvakatipoteredza inoratidza kuti imazamox haifanirwe kuramba iri mumvura isina kudzika pamusoro pemvura.Zvisinei, inofanira kuramba iri mumvura pakadzika dzika kana anaerobic nharaunda iripo uye apo photolytic degradation haisi chinhu.

Imazamox inenge isiri muchetura kumvura yakachena uye hove estuarine uye invertebrates pane acute exposure basis.Yakanyanya uye isingaperi toxicity data inoratidzawo kuti imazamox haina chepfu kune zvinoyamwisa.
