摘要:
The invention relates to ureas having a herbicidal and plant growth-regulating action of the formula ##STR1## in which R.sup.1 and R.sup.2 each represents, independently of the other, hydrogen, halogen, C.sub.1 -C.sub.6 -alkyl C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, C.sub.1 -C.sub.4 -alkoxycarbonyl, C.sub.1 -C.sub.4 -alkoxy-(C.sub.1 -C.sub.4)-alkyl, nitro or cyano, andR.sup.3 and R.sup.4 each represents, independently of the other, hydrogen, halogen, cyano, OH, SH, C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, C.sub.1 -C.sub.4 -alkylthio, C.sub.1 -C.sub.4 -haloalkylthio, amino, mono-C.sub.1 -C.sub.4 -alkylamino, di-C.sub.1 -C.sub.4 -alkylamino, C.sub.1 -C.sub.4 -alkoxycarbonyl or C.sub.1 -C.sub.4 -alkoxy-(C.sub.1 -C.sub.4)-alkyl,processes and intermediates for the preparation thereof, and herbicidal and plant growth-regulating compositions containing a compound of the formula I.
