Fluorophenoxy compounds, herbicidal compositions and methods

摘要

Certain novel fluorophenoxy compounds, principally aryloxyfluorophenoxyalkanoic acids and derivatives thereof, are described. More specifically, these novel compounds bear 1 to 4 fluorine substituents on the phenyl ring. These novel compounds exhibit surprising preemergent and postermergent activity when used according to the method of the invention in the control of grassy weeds.
