SABRE 48 SC is a triketone herbicide which inhibits the enzyme p-hydroxyphenyl-pyruvate dioxygenase (HPPD),disrupting carotenoid biosynthesis. This process leads to the destruction of chlorophyll, resulting in a bleaching effect in susceptible plants. SABRE 48 SC is intended for pre-emergence, and post emergence use for the selective control of annual broadleaf weeds.
