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

I-Cyhalofop-butyl ester iyi-herbicide ebalulekile esetshenziswa kakhulu ekulimeni irayisi kodwa futhi isetshenziswa nakwezinye izinhlelo zezitshalo. Ihlukaniswe njengelungu leqembu le-aryloxyphenoxypropionate, yaziwa ngesenzo sayo sokukhetha ngokumelene nokhula lotshani ngenkathi iphephile ezitshalweni ezinamahlamvu abanzi, okubalulekile ezinhlelweni zokuphathwa kokhula ezihlanganisiwe. Ngokwemishini, i-cyhalofop-butyl isebenza ngokuvimbela i-acetyl-CoA carboxylase (ACCase), i-enzyme ebalulekile endleleni yokwenza i-fatty acid biosynthesis ezitshalweni. Ngokuphazamisa le nqubo ye-metabolic, i-herbicide ivimbela ngempumelelo ukukhula kwezinhlobo zotshani ezibucayi, okuholela ekufeni kwazo ngenkathi ivumela isivuno ukuba sichume. Lesi senzo sokukhetha sibangelwa izindlela ezithile ze-biochemical eziqondiswe yi-herbicide, ezikhona otshanini kodwa hhayi ezitshalweni ezinamahlamvu abanzi ezivame ukuhambisana nazo. Ukusetshenziswa kwe-cyhalofop-butyl kungenziwa ngokufafaza emhlabathini nangaphandle, ngokuvamile kuhambisana namanye amasu okuphatha ukhula. Isimo sayo sesistimu sisho ukuthi imuncwa ngamaqabunga nezimpande, okuvumela ukulawula okuphumelelayo kokubili imbewu yokhula evele kanye nengase ihlume. Ngokuphathelene nomthelela wemvelo, i-cyhalofop-butyl ihlolwa ngephrofayili yayo yokuphepha, ngezifundo ezenziwe ukuhlola imiphumela yayo ezintweni eziphilayo ezingahlosiwe kanye namathuba okungcoliswa kwamanzi angaphansi komhlaba. Izindlela zokusebenzisa ezifanele kanye nokunamathela kumthamo onconywayo kubalulekile ekunciphiseni izingozi ezindaweni zemvelo ezizungezile. Sekukonke, i-cyhalofop-butyl ester imele impahla ebalulekile ekusetshenzisweni kokubulala ukhula kwabalimi, ikakhulukazi ezindaweni lapho ukhula lotshani luyinselele enkulu ekuvuneni kwezitshalo, ukuqinisekisa ukuphathwa kokhula okuphumelelayo ngenkathi kukhuthazwa imikhuba yezolimo esimeme.
