    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: The invention is concerned with new herbicidally active 4-phenoxy-.alpha.-phenoxy-alkanecarboxylic acid derivatives, especially propionic acid esters of the type ##STR1## bearing in the first phenoxy radical a nitro group besides another substituent R.sub.1 which is preferably a halogen atom, the CF.sub.3 group is lower alkyl, alkoxy or alkoxycarbonyl group. The invention is further concerned with herbicidal compositions containing such new derivatives and with methods for the selective control of grass-like weeds in crops of dicotyledonous and monocotyledonous cultivated plants such as cereals.
