Topramezone ke sebolaya-mofuta sa pele se hlahisitsweng ke BASF kamora ho lema masimo a poone, e leng sethibela-mofuta sa 4-hydroxyphenylpyruvate oxidase (4-HPPD). Ho tloha ha e qala ho sebediswa ka 2011, lebitso la sehlahiswa "Baowei" le thathamisitswe Chaena, le roba diphoso tsa polokeho ya dibolaya-mofuta tsa poone tse tlwaelehileng mme le hohela tlhokomelo ya indasteri.
Molemo o hlahelletseng ka ho fetisisa oa topramezone ke polokeho ea eona bakeng sa poone le lijalo tse latelang, 'me e sebelisoa haholo hoo e batlang e le mefuta eohle ea poone joalo ka poone e tloaelehileng, poone e mafura, poone e tsoekere, poone ea tšimo le popcorn. Ka nako e ts'oanang, e na le mefuta e mengata ea litlama, ts'ebetso e phahameng, le ho kopana ho matla, 'me e na le litlamorao tse ntle tsa taolo holim'a mofoka o hanelang glyphosate, triazine, acetyllactate synthase (ALS) inhibitors, le acetyl CoA carboxylase (ACCase) inhibitors.
Ho ea ka litlaleho, lilemong tsa morao tjena, ha mofoka o sa mamelleheng masimong a poone o ntse o thatafalloa ho o laola, phaello le katleho ea taolo ea meriana e bolaeang likokoanyana ea koae le nitrate e fokotsehile, 'me lik'hamphani tsa meriana e bolaeang likokoanyana tsa malapeng li ela hloko haholo topramezone.
