N-(Cyclopropyl-pyrimidinyl)-N'-aryl-sulfonyl ureas of the formula <IMAGE> (I) wherein Ar is a phenyl group <IMAGE> or a naphthyl group and Q is a group X-A or R3, A is alkynyl, alkyl which is unsubstituted or substituted by halogen, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, haloalkoxy, haloalkylthio, haloalkylsulfinyl or haloalkylsulfonyl, or alkenyl which is unsubstituted or substituted by the substituents given above for alkyl, or A is a phenyl or benzyl group, E is methine, X is oxygen, sulfur, or a sulfinyl or sulfonyl bridge, Z is oxygen or sulfur, R1 is hydrogen, alkyl or alkoxy, R2 is halogen, alkyl, haloalkyl, alkoxy, haloalkoxy, amino, alkylamino, di-alkylamino, cycloalkyl or alkoxyalkyl, R3 is hydrogen, halogen, alkyl, alkenyl, haloalkyl, -CO-NR8R9, -CN, -COR10, -NR1R7 or -NR1-COR12, R4 is hydrogen, alkyl, alkoxy, alkylthio, haloalkyl, haloalkoxy, halogen, or alkoxyalkyl, R5 is independently selected from the same groups as R3 or -X-R6, R6 and R7 are each alkyl, alkenyl or alkynyl, R8 and R9 independently of one another are each hydrogen, alkyl, alkenyl or alkynyl, R10 is hydrogen, alkyl or haloalkyl, R11 is hydrogen, alkyl, haloalkyl, alkenyl, alkynyl, phenyl or benzyl, and R12 is the same as R1 but independent thereof, and the salts of these compounds with amines, metal bases, or quaternary ammonium bases, have good herbicidal and plant-growth-regulating properties.
