i-cyhalofop butyl ester CAS:122008-85-9

I-Cyhalofop-butyl ester sisibulali-zinambuzane esibalulekileyo esisetyenziswa kakhulu ekulimeni irayisi kodwa sikwasetyenziswa nakwezinye iinkqubo zezityalo. Ihlelwe njengelungu leqela le-aryloxyphenoxypropionate, yaziwa ngesenzo sayo sokukhetha ngokuchasene nokhula lwengca ngelixa ikhuselekile kwizityalo ezinamagqabi abanzi, nto leyo ibalulekileyo kwiinkqubo zolawulo lokhula oludibeneyo. Ngokwendlela yokusebenza, i-cyhalofop-butyl isebenza ngokuthintela i-acetyl-CoA carboxylase (ACCase), i-enzyme ebalulekileyo kwindlela yokwenza i-fatty acid biosynthesis kwizityalo. Ngokuphazamisa le nkqubo ye-metabolic, isibulali-zinambuzane siyathintela ukukhula kweentlobo zengca ezinobuthathaka, nto leyo ekhokelela ekufeni kwazo ngelixa sivumela isityalo ukuba sichume. Esi senzo sokukhetha sibangelwa ziindlela ezithile ze-biochemical ezijoliswe yi-herbicide, ezikhoyo kwiingca kodwa kungekhona kwizityalo ezinamagqabi abanzi ezihlala zihamba nazo. Ukusetyenziswa kwe-cyhalofop-butyl kunokwenziwa ngokutshiza emhlabeni nangaphandle, rhoqo kunye nezinye iindlela zokulawula ukhula. Indalo yayo yenkqubo ithetha ukuba ifunxwa ngamagqabi kunye neengcambu, okuvumela ulawulo olusebenzayo lwembewu yokhula evele kunye nenokuhluma. Ngokuphathelele impembelelo yokusingqongileyo, i-cyhalofop-butyl ivavanywa ngenxa yokhuseleko lwayo, kunye nezifundo ezenziweyo ukuvavanya imiphumo yayo kwizinto eziphilayo ezingajoliswanga kunye nokubakho kokungcoliswa kwamanzi angaphantsi komhlaba. Iindlela ezifanelekileyo zokusetyenziswa kunye nokunamathela kwimilinganiselo ecetyiswayo kubalulekile ekunciphiseni iingozi kwiindawo ezingqongileyo. Ngokubanzi, i-cyhalofop-butyl ester imele i-asethi ebalulekileyo kwizixhobo zokubulala ukhula kubalimi, ngakumbi kwiindawo apho ukhula lwengca lubangela umngeni omkhulu kwisivuno sezityalo, ukuqinisekisa ulawulo olusebenzayo lokhula ngelixa kukhuthazwa iindlela zolimo ezizinzileyo.
