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.
