Abstract

Aromatic carboxylic acid derivatives of the formula ##STR1## in which the radical ##STR2## is a substituted or unsubstituted quinoline, naphthalene, benzofuran, thiophene or pyridine radical, PA0 R.sup.1 is hydrogen, alkylidenaminoxy, unsubstituted or substituted cycloalkylidenaminoxy, succinyliminoxy, unsubstituted or substituted alkenyloxy, alkynyloxy, azolyl, alkylsulfonylamino, alkoxycarbonylalkyloxy, N-azolylalkyloxy, unsubstituted or substituted alkoxy, unsubstituted or substituted phenylalkoxy, hydroxyl or the radical O.sup..crclbar. M.sup..sym., M.sup..sym. being one equivalent of an alkali metal, alkaline earth metal or organic ammonium ion, PA0 R.sup.2 and R.sup.3 are alkyl, haloalkyl, alkoxy, haloalkoxy or alkylthio, PA0 X is oxygen or sulfur, PA0 Y and Z are nitrogen or the methine group, and PA0 R.sup.4 and R.sup.5 are hydrogen, halogen, alkyl, haloalkyl, nitro, alkoxy, unsubstituted or substituted alkenyloxy, acylamino, alkylamino, dialkylamino or arylamino, and their use for controlling the growth of unwanted plants.
