    摘要: A class of herbicidal unsaturated esters of .alpha.-[4-(3',5'-dihalogeno-pyridyl-2'-oxy)-phenoxy]-propionic and -thiolpropionic acid of the formula ##STR1## wherein Hal is chlorine or bromine, X is oxygen or sulfur, and R is an unsubstituted or halogenated aliphatic or alicyclic radical which may contain nitrogen, and which possesses at least one double and/or triple bond, with the proviso that if X is oxygen, R is not an unsubstituted alkenyl radical. These new esters are useful for selective post-emergent control of grassy weeds in cultivated plants such as wheat, barley, rice and soybean.

    摘要: 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 ##STR1## 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 C.sub.2 -C.sub.6 alkyl group, andQ is an amino or ammonium group.
