Topramezone yog thawj cov tshuaj tua kab tom qab cog qoob loo uas BASF tsim rau cov teb pob kws, uas yog 4-hydroxyphenylpyruvate oxidase (4-HPPD) inhibitor. Txij li thaum nws tso tawm xyoo 2011, lub npe khoom "Baowei" tau teev nyob rau hauv Suav teb, rhuav tshem cov teeb meem kev nyab xeeb ntawm cov tshuaj tua kab hauv teb pob kws thiab nyiam kev lag luam.
Qhov zoo tshaj plaws ntawm topramezone yog nws txoj kev nyab xeeb rau pob kws thiab cov qoob loo tom qab, thiab nws siv dav hauv yuav luag txhua hom pob kws xws li pob kws ib txwm, pob kws glutinous, pob kws qab zib, pob kws teb, thiab pob kws paj kws. Tib lub sijhawm, nws muaj cov tshuaj tua kab dav dav, kev ua haujlwm siab, thiab kev sib xyaw ua ke zoo, thiab muaj cov teebmeem tswj tau zoo rau cov nroj tsuag uas tiv taus glyphosate, triazine, acetyllactate synthase (ALS) inhibitors, thiab acetyl CoA carboxylase (ACCase) inhibitors.
Raws li cov lus ceeb toom, nyob rau xyoo tas los no, vim tias cov nroj tsuag uas tiv taus hauv cov teb pob kws tau dhau los ua qhov nyuaj rau tswj, qhov txiaj ntsig thiab kev tswj hwm zoo ntawm cov tshuaj tua kab mob haus luam yeeb thiab nitrate tau txo qis, thiab cov tuam txhab tshuaj tua kab hauv tsev tau them sai sai rau topramezone. Nrog rau kev tas sij hawm ntawm BASF daim ntawv pov thawj hauv Suav teb (daim ntawv pov thawj ZL98802797.6 rau topramezone tas sij hawm rau Lub Ib Hlis 8, 2018), cov txheej txheem localization ntawm cov tshuaj qub kuj tseem nce qib, thiab nws lub khw yuav maj mam qhib.
Xyoo 2014, kev muag khoom thoob ntiaj teb ntawm topramezone yog 85 lab daus las Asmeskas, thiab xyoo 2017, kev muag khoom thoob ntiaj teb tau nce mus txog qhov siab tshaj plaws ntawm 124 lab daus las Asmeskas, qeb thib plaub ntawm cov tshuaj tua kab HPPD inhibitor (peb sab saum toj yog nitrosulfuron, isoxacloprid, thiab cyclosulfuron). Tsis tas li ntawd, cov tuam txhab xws li Bayer thiab Syngenta tau pom zoo los koom ua ke tsim cov taum pauv HPPD, uas kuj tau pab txhawb rau kev loj hlob ntawm kev muag khoom ntawm topramezone. Los ntawm qhov kev xav ntawm qhov ntim muag khoom thoob ntiaj teb, cov khw muag khoom tseem ceeb ntawm topramezone yog nyob rau hauv cov tebchaws xws li Tebchaws Meskas, Lub Tebchaws Yelemees, Tuam Tshoj, Is Nrias teb, Indonesia, thiab Mexico.
