Mesotrione bụ ahịhịa ọhụrụ a na-emepụta maka njikwa nhọrọ tupu na mgbe ọbịpụtachara nke ọtụtụ ụdị akwụkwọ ndụ akwụkwọ ndụ na ahịhịa ahịhịa na ọka (Zea mays).Ọ bụ otu n'ime ezinụlọ benzoylcyclohexane-1,3-dione nke herbicides, nke sitere na kemịkalụ sitere na phytotoxin sitere n'okike enwetara site na osisi ahịhịa Californian, Callistemon citrinus.Ngwakọta ahụ na-arụ ọrụ site na mgbochi asọmpi nke enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD), akụkụ nke ụzọ biochemical nke na-agbanwe tyrosine na plastoquinone na alfa-tocopherol.Mesotrione bụ ihe mgbochi siri ike nke HPPD sitere na Arabidopsis thaliana, yana uru Ki nke c 6-18 pM.A na-ebuli ya ngwa ngwa site na ụdị ahihia na-esote ngwa foliar, ma na-ekesa ya n'ime osisi site na ma acropetal na basipetal ije.Maize na-anabata mesotrione n'ihi nhọpụta nke mkpụrụ ndụ ihe nketa site na ihe ọkụkụ.Iji nwayo nke mesotrione, n'ihe gbasara ụdị ahihia nwere ike ime, nwekwara ike itinye aka na uru ya dị ka ahịhịa ahịhịa ahọpụtara maka ojiji na ọka.Mesotrione na-enye njikwa nke ahịhịa ndị nwere nnukwu akwụkwọ, yana enwere ike iji ya na mmemme njikwa ahihia agbakwunyere dabere na atụmatụ njikwa ahịhịa na-amasị onye na-akụ ahịhịa.

Mesotrione na-egbochi enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD).Ọ bụ ihe mgbochi siri ike nke HPPD na nyocha ụlọ nyocha na-eji osisi Arabidopsis thaliana, yana uru Ki dị ihe dịka 10 pM.Na osisi, HPPD dị mkpa maka biosynthesis nke tocopherols na nke plastoquinone, nke dị mkpa maka mmepụta carotenoid.Mgbochi nke ụzọ ahụ na-eduga n'ịchacha akwụkwọ ka chlorophyll na-emebi emebi, na-esote ọnwụ osisi.

Mesotrione bụ ahịhịa ahịhịa na-ebute ụzọ na mgbe ọ pụtachara maka nhọpụta kọntaktị na njikwa fọdụrụnụ nke ahịhịa ahịhịa n'ọhịa, ọka mkpụrụ, popcorn odo na ọka dị ụtọ.
