Topramezone yog thawj zaug cog qoob loo tshuaj tua kab tsim los ntawm BASF rau pob kws teb, uas yog 4-hydroxyphenylpyruvate oxidase (4-HPPD) inhibitor.Txij li thaum nws tso tawm xyoo 2011, cov khoom npe "Baowei" tau teev nyob rau hauv Suav teb, rhuav tshem kev nyab xeeb tsis xws luag ntawm cov khoom siv cog qoob loo cog qoob loo 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 ntej, thiab nws tau siv dav hauv yuav luag txhua hom pob kws xws li pob kws tsis tu ncua, glutinous pob kws, pob kws qab zib, pob kws teb, thiab paj kws.Nyob rau tib lub sijhawm, nws muaj cov tshuaj tua kab dav dav, kev ua haujlwm siab, thiab muaj zog miscibility, thiab muaj kev tswj zoo ntawm 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 hauv xyoo tas los no, raws li cov nroj tsuag resistant nyob rau hauv pob kws teb tau dhau los ua nyuaj rau kev tswj, cov txiaj ntsig thiab kev tswj cov txiaj ntsig ntawm cov tshuaj yeeb tshuaj thiab nitrate tshuaj tua kab tau txo qis, thiab cov tuam txhab tshuaj tua kab hauv tsev tau them nyiaj rau topramezone.Nrog rau qhov tas sij hawm ntawm BASF's patent nyob rau hauv Suav teb (patent naj npawb ZL98802797.6 rau topramezone tas sij hawm thaum Lub Ib Hlis 8, 2018), cov txheej txheem hauv cheeb tsam ntawm cov tshuaj thawj zaug kuj tseem nce mus ntxiv, thiab nws cov lag luam yuav maj mam qhib.
Hauv 2014, kev muag khoom thoob ntiaj teb ntawm topramezone yog 85 lab US las, thiab hauv 2017, kev muag khoom thoob ntiaj teb tau nce mus rau keeb kwm siab ntawm 124 lab US las, qeb thib plaub ntawm HPPD inhibitor herbicides (qhov peb sab saum toj yog nitrosulfuron, isoxacloprid, thiab cyclosulfuron).Tsis tas li ntawd, cov tuam txhab xws li Bayer thiab Syngenta tau ua tiav qhov kev pom zoo los koom ua ke tsim HPPD cov taum ntev ntev, uas kuj tau pab txhawb kev loj hlob ntawm kev muag khoom ntawm topramezone.Los ntawm qhov kev xav ntawm kev muag khoom thoob ntiaj teb, kev muag khoom tseem ceeb ntawm topramezone yog nyob rau hauv cov teb chaws xws li Tebchaws Meskas, Lub Tebchaws Yelemees, Tuam Tshoj, Is Nrias teb, Indonesia, thiab Mexico.
