Definition
ChEBI: Bispyribac-sodium is the organic sodium salt of bispyribac. It is used as a broad spectrum post-emergent herbicide for the control of grasses, sedges and broadleaf weeds in rice crops. It has a role as a herbicide, an agrochemical and an environmental contaminant. It contains a bispyribac(1-).
Metabolic pathway
More than 90% of the radioactivity is excreted in rat
urine 96 h after the rats are orally administered 14C-
bispyribac sodium. Most of the radioactivity detected in
the urine, feces, liver, and plasma consists of
unchanged bispyribac sodium. The metabolites
identified are derived from hydroxylation on the
pyrimidine ring, O-demethylation, cleavage of the ether
linkage between pyrimidine and phenyl rings yielding
5-hydroxylated and mono-O-desmethylbispyribac
acids, and salicylic acid and 2-pyrimidinole derivatives.
