Identification
Common NameNorflurazon
ClassSmall Molecule
DescriptionNorflurazon is a pyridazinone herbicide used to control grass and broadleaf weeds. Norflurazon inhibits carotenoid synthesis, which causes chlorophyll depletion and inhibition of photosynthesis in plants. Norflurazon has low toxicity if individuals accidentally eat residues, and very low toxicity if it is inhaled or gets on skin.
