Bicyclopyrone belongs to the hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor class of herbicides. It acts by blocking the function of HPPD required for producing essential compounds for carotenoid pigments. Without carotenoid pigments, the plant bleaches and eventually dies.
ChEBI: Bicyclopyrone is a member of the class of pyridines that is pyridine which is substituted at positions 2, 3, and 6 by (2-methoxyethoxy)methyl, (2-hydroxy-4-oxobicyclo[3.2.1]oct-2-en-3-yl)carbonyl, and trifluoromethyl groups, respectively. It is a broad-spectrum herbicide developed by Syngenta and used for the pre- and post-emergence control of weeds in corn. It has a role as a herbicide, an agrochemical and a carotenoid biosynthesis inhibitor. It is a member of pyridines, an aromatic ketone, a carbobicyclic compound, a beta-diketone, an organofluorine compound, an ether, an enol and an enone.
