Abstract
Abstract Pridyloxy-phenoxy-propionic acid-amino-alkyl esters having a herbicidal action, their production, compositions containing them, and the use thereof are described. The esters correspond to the formula <IMAGE> in which X is halogen or trifluoromethyl, Y is hydrogen, halogen or trifluoromethyl, Z is oxygen or sulfur, "alkylene" is a straight-chain or branched-chain C2-C6 alkyl group, and Q is an amino or ammonium group.
