Uphuhliso lwamva nje lweTopramezone

I-Topramezone yi-post seedling herbicide yokuqala eyenziwe yi-BASF kwintsimi yengqolowa, eyi-4-hydroxyphenylpyruvate oxidase (4-HPPD) inhibitor.Ukusukela ekusungulweni kwayo ngo-2011, igama lemveliso elithi "Baowei" lidweliswe e-China, lisusa iziphene zokhuseleko lwemichiza yokutshabalalisa ukhula kwintsimi yombona kunye nokutsala umdla kushishino.

Olona ncedo lubalaseleyo lwe-topramezone lukhuseleko lwayo lombona kunye nezityalo ezilandelayo, kwaye isetyenziswa kakhulu phantse kuzo zonke iintlobo zombona ezifana nombona oqhelekileyo, umbona otyebileyo, umbona oswiti, umbona wasendle, kunye neepopcorn.Ngelo xesha, inomlinganiselo obanzi we-herbicide, umsebenzi ophezulu, kunye ne-miscibility enamandla, kwaye inemiphumo emihle yokulawula ukhula oluchasene ne-glyphosate, i-triazine, i-acetyllactate synthase (ALS) inhibitors, kunye ne-acetyl CoA carboxylase (ACCase) inhibitors.

Ngokutsho kweengxelo, kwiminyaka yakutshanje, njengoko ukhula oluxhathisayo kumasimi ombona luye lwaba nzima ngakumbi ukulawula, ingeniso kunye nokulawula ukusebenza kwecuba kunye ne-nitrate ye-herbicide yehla, kwaye iinkampani zasekhaya ezibulala izinambuzane ziye zanikela ingqalelo engakumbi kwi-topramezone.Ngokuphelelwa kwelungelo lomenzi we-BASF e-China (inombolo ye-patent ZL98802797.6 ye-topramezone iphelelwe ngoJanuwari 8, 2018), inkqubo ye-localization yechiza lokuqala nayo iqhubela phambili ngokuthe ngcembe, kwaye imarike yayo iya kuvuleka ngokuthe ngcembe.

Ngo-2014, ukuthengiswa kwehlabathi jikelele kwe-topramezone kwakuyi-85 yezigidi zeedola zase-US, kwaye ngo-2017, ukuthengiswa kwehlabathi kunyuke kwimbali ephezulu ye-124 yezigidi zeedola zase-US, kwindawo yesine phakathi kwe-HPPD inhibitor herbicides (ezintathu eziphezulu ziyi-nitrosulfuron, isoxacloprid, kunye ne-cyclosulfuron).Ukongeza, iinkampani ezifana ne-Bayer kunye ne-Syngenta ziye zafikelela kwisivumelwano sokuphuhlisa ngokudibeneyo iimbotyi zesoya ezinyamezelayo ze-HPPD, eziye zanegalelo ekukhuleni kwentengiso ye-topramezone.Ngokwembono yomthamo wentengiso yehlabathi, iimarike eziphambili zentengiso ye-topramezone zikumazwe anje nge-United States, iJamani, i-China, i-Indiya, i-Indonesia, ne-Mexico.
