Topramezone ndiyo yekutanga post seedling herbicide yakagadzirwa neBASF yeminda yechibage, inova 4-hydroxyphenylpyruvate oxidase (4-HPPD) inhibitor.Kubva payakatangwa muna 2011, zita rechigadzirwa rekuti "Baowei" rakanyorwa kuChina, richityora kuchengetedzwa kwemishonga yesora yechibage uye kukwezva kutarisisa kweindasitiri.
Kunyanya kukosha kwetopramezone ndiko kuchengetedza kwayo chibage uye zvirimwa zvinotevera, uye inoshandiswa zvakanyanya mumhando dzese dzechibage dzakadai sechibage chenguva dzose, chibage chinokora, chibage chinotapira, chibage chemumunda, uye popcorn.Panguva imwecheteyo, ine yakakura yeherbicide spectrum, yakakwirira basa, uye yakasimba miscibility, uye ine zvakanaka kudzora mhedzisiro pasora rinopesana neglyphosate, triazine, acetyllactate synthase (ALS) inhibitors, uye acetyl CoA carboxylase (ACCase) inhibitors.
Maererano nemishumo, mumakore achangopfuura, sezvo sora risingamiri muminda yechibage zvaramba richinetsa kudzora, purofiti uye kudzora kushanda kwefodya yechinyakare nemishonga yenitrate yadzikira, uye makambani emishonga ezvipembenene emumba ave achiwedzera kukoshesa topramezone.Nekupera kwebasa reBASF's patent muChina (patent nhamba ZL98802797.6 ye topramezone yakapera musi wa8 Ndira 2018), maitiro ekugadzirisa mushonga wepakutanga ari kufambira mberi zvishoma nezvishoma, uye musika wayo unozovhurwa zvishoma nezvishoma.
Muna 2014, kutengesa kwepasi rose kwetopramezone kwaive 85 miriyoni emadhora ekuAmerica, uye muna 2017, kutengesa kwepasi rose kwakakwira kusvika panhoroondo yepamusoro yemadhora zana nemakumi maviri nemana emadhora ekuAmerica, pachinzvimbo chechina pakati peHPPD inhibitor herbicides (vatatu vepamusoro vari nitrosulfuron, isoxacloprid, uye cyclosulfuron).Pamusoro pezvo, makambani akaita seBayer neSyngenta asvika pachibvumirano chekugadzira pamwe HPPD inoshivirira soya beans, izvo zvakabatsirawo mukukura kwekutengesa kwetopramezone.Kubva pamaonero ehuwandu hwekutengesa kwepasirese, misika mikuru yekutengesa yetopramezone iri munyika dzakaita seUnited States, Germany, China, India, Indonesia, neMexico.
