Saflufenacil

Saflufenacil is an herbicide of the pyrimidinedione chemical class used to control annual broadleaf weeds in soybeans and corn. It was developed by BASF and is marketed under the Kixor trademark.

Saflufenacil works by inhibiting protoporphyrinogen IX oxidase (PPO), resulting in in planta accumulations of protoporphyrin IX (proto) and H2O2; inhibiting PPO formation results in prevention of chlorophyll, heme, and cytochrome synthesis; also, proto accumulation causes lipid peroxidation, resulting in rapid loss of membrane integrity and function; only slight increases of proto and H2O2 occur in corn.
