ʻO Topramezone ka lāʻau lapaʻau mua ma hope o ka kanu ʻana i hoʻomohala ʻia e BASF no nā māla kulina, ʻo ia ka mea 4-hydroxyphenylpyruvate oxidase (4-HPPD) inhibitor.Mai kona hoʻomaka ʻana i ka makahiki 2011, ua helu ʻia ka inoa huahana ʻo "Baowei" ma Kina, e uhaʻi ana i nā hemahema palekana o nā lāʻau lapaʻau kuʻuna maʻamau a me ka huki ʻana i ka ʻoihana.
ʻO ka pōmaikaʻi koʻikoʻi o ka topramezone, ʻo ia ka palekana no ke kulina a me nā mea kanu ma hope, a hoʻohana nui ʻia i nā ʻano kulina āpau e like me ke kulina maʻamau, ke kulina paʻa, ke kulina momona, ke kulina māla, a me ka popcorn.I ka manawa like, loaʻa iā ia kahi ʻano herbicide ākea, hana kiʻekiʻe, a me ka miscibility ikaika, a he mau hopena hoʻomalu maikaʻi i nā nāhelehele i kū i ka glyphosate, triazine, acetyllactate synthase (ALS) inhibitors, a me acetyl CoA carboxylase (ACCase) inhibitors.
Wahi a nā hōʻike, i kēia mau makahiki i hala iho nei, ʻoiai ua paʻakikī loa ka mālama ʻana i nā nāhelehele kūʻokoʻa i ka māla kulina, ua emi ka waiwai a me ka hoʻomalu ʻana o ka paka kahiko a me ka nitrate herbicides, a ua hoʻonui nā ʻoihana pesticide i ka topramezone.Me ka pau ʻana o ka patent a BASF ma Kina (ka helu patent ZL98802797.6 no topramezone i pau ma Ianuali 8, 2018), ke holomua nei ke kaʻina hana localization o ka lāʻau mua, a e wehe mālie ana kāna mākeke.
I ka makahiki 2014, he 85 miliona mau dala o ke ao holookoa o topramezone, a ma ka makahiki 2017, ua pii ke kuai honua i ka 124 miliona dala o Amerika, i ka ha o na laau hoohiolo HPPD (o na mea ekolu o ka nitrosulfuron, isoxacloprid, a me cyclosulfuron).Eia kekahi, ʻo nā hui e like me Bayer a me Syngenta ua loaʻa i kahi ʻaelike e hoʻomohala pū i ka HPPD tolerant soybeans, a ua kōkua pū i ka ulu ʻana o ke kūʻai aku o topramezone.Mai ka hiʻohiʻona o ka nui kūʻai kūʻai honua, aia nā mākeke kūʻai nui o topramezone ma nā ʻāina e like me ʻAmelika Hui Pū ʻIa, Kelemānia, Kina, India, Indonesia, a me Mexico.
