  Certain novel pyridinyloxyphenoxy alkanoic acids, pyri- dinylthiophenoxy alkanoic acids, derivatives thereof and related compounds are described. More specifically, these novel compounds bear a fluorine substituent in the 3- position of the pyridinyl group and in the 5-position the substituent is selected from chlorine, CF3, CF2CI or CF2H. These novel compounds exhibit surprising preemergent and postemergent activity in the control of grassy weeds.
