Abstract
The present invention concerns new .alpha.-[4-(5'-trifluoromethyl-pyrid-2'-yl)oxy-phenoxy]-propionic-acid derivatives of the formula ##STR1## wherein R.sub.1 and R.sub.2 independently are hydrogen, halogen, cyano or lower alkyl, and PA0 Z is a radical --COR.sub.3 or a 2-oxazoline group, whereby R.sub.3 is the hydroxyl group or a salt form thereof, or is an ester, thioester, amide or hydrazide group on said propionic acid. These new propionic acid derivatives have herbicidal and plant growth regulating activity and may be worked up into compositions containing them.
