I-Topramezone iyi-herbicide yokuqala ngemuva kokutshala ethuthukiswe yi-BASF yamasimu ommbila, okuyi-4-hydroxyphenylpyruvate oxidase (4-HPPD) inhibitor. Selokhu yethulwa ngo-2011, igama lomkhiqizo elithi "Baowei" libhalwe eShayina, liphula amaphutha okuphepha kwemithi yokubulala ukhula evamile yasemasimini ommbila futhi lidonsela ukunaka embonini.
Inzuzo evelele kakhulu ye-topramezone ukuphepha kwayo kummbila kanye nezitshalo ezilandelayo, futhi isetshenziswa kabanzi cishe kuzo zonke izinhlobo zommbila ezifana nommbila ojwayelekile, ummbila onamafutha amaningi, ummbila omnandi, ummbila wasensimini, kanye ne-popcorn. Ngesikhathi esifanayo, ine-spectrum ebanzi yokubulala ukhula, umsebenzi ophezulu, kanye nokuxubana okunamandla, futhi inemiphumela emihle yokulawula okhula olumelana ne-glyphosate, i-triazine, i-acetyllactate synthase (ALS), kanye ne-acetyl CoA carboxylase (ACCase) inhibitors.
Ngokusho kwemibiko, eminyakeni yamuva nje, njengoba ukhula olumelana nemithi yokulima seluya luba nzima kakhulu ukululawula, inzuzo kanye nokusebenza kahle kokulawula imithi yokubulala ukhula yendabuko kagwayi kanye ne-nitrate kuye kwehla, kanti izinkampani zokubulala ukhula zasekhaya ziye zanaka kakhulu i-topramezone. Njengoba i-patent ye-BASF iphelelwe yisikhathi eShayina (inombolo ye-patent ZL98802797.6 ye-topramezone iphelelwe yisikhathi ngoJanuwari 8, 2018), inqubo yokwenziwa kwendawo yomuthi wokuqala nayo iyaqhubeka ithuthuka, futhi imakethe yayo izovuleka kancane kancane.
Ngo-2014, ukuthengiswa komhlaba wonke kwe-topramezone kwakungamadola aseMelika ayizigidi ezingama-85, kwathi ngo-2017, ukuthengiswa komhlaba wonke kwakhuphuka kwafinyelela ezingeni eliphezulu emlandweni lamadola aseMelika ayizigidi eziyi-124, okubekwe endaweni yesine phakathi kwemithi yokubulala ukhula ye-HPPD (emithathu ephezulu yi-nitrosulfuron, i-isoxacloprid, kanye ne-cyclosulfuron). Ngaphezu kwalokho, izinkampani ezifana neBayer kanye neSyngenta zifinyelele esivumelwaneni sokuthuthukisa ngokubambisana ubhontshisi wesoya obekezelela i-HPPD, okuye kwaba negalelo ekukhuleni kokuthengiswa kwe-topramezone. Ngokombono womthamo wokuthengisa emhlabeni wonke, izimakethe zokuthengisa eziyinhloko ze-topramezone zisemazweni afana ne-United States, iJalimane, iShayina, iNdiya, i-Indonesia, kanye neMexico.
