    摘要: Herbicidal agents containing as active ingredient a compound of the formula ##STR1## in which R represents halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.2 -alkoxy or C.sub.1 -C.sub.2 -alkylthio, C.sub.1 -C.sub.2 -halogeno-alkyl, NO.sub.2 SO.sub.2 CH.sub.3, SO.sub.2 NH.sub.2, --COOCH.sub.3, CN, with the proviso that R.sub.2 cannot be alkoxy when (R).sub.n is alkyl, R.sub.1 and R.sub.3 represent C.sub.1 -C.sub.6 -alkyl, R.sub.2 represents C.sub.1 -C.sub.6 -alkyl, CH.sub.2 Cl or C.sub.1 -C.sub.6 -alkoxy, X is oxygen or sulfur and n is an integer of from 1 to 3 are especially useful for combatting annual weed grasses in dicotyledonous and even monocotyledonous crop plants.
