ABSTRACT:
Certain novel pyridinyloxyphenoxy alkanoic acids, pyridinylthiophenoxy 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, CF.sub.3, CF.sub.2 Cl or CF.sub.2 H. These novel compounds exhibit surprising preemergent and postemergent activity in the control of grassy weeds.
