N-(Cyclopropyl-triazinyl- and -pyrimidinyl)-N'-arylsulfonyl ureas of the formula STR1 wherein Ar is a phenyl group STR2 or a naphthyl group STR3 and Q is a group X-A or R3, A is a C3 -C6 -alkynyl group, a C1 -C6 -alkyl group which is unsubstituted or substituted by halogen, C1 -C4 -alkoxy, C1 -C4 -alkylthio, C1 -C4 -alkylsulfinyl, C1 -C4 -alkylsulfonyl, C1 -C4 -haloalkoxy, C1 -C4 -haloalkylthio, C1 -C4 -haloalkylsulfinyl or C1 -C4 -haloalkylsulfonyl, or a C2 -C6 -alkenyl group which is unsubstituted or substituted by the groups given in the foregoing for C1 -C6 -alkyl, or A is a phenyl or benzyl group, E is the methine group or nitrogen, X is oxygen, sulfur, or a sulfinyl or sulfonyl bridge, Z is oxygen or sulfur, R1 is hydrogen, C1 -C4 -alkyl or C1 -C4 -alkoxy, R2 is halogen, C1 -C3 -alkyl, C1 -C3 -haloalkyl, C1 -C3 -alkoxy, C1 -C3 -haloalkoxy, amino, C1 -C3 -alkylamino, di-(C1 -C3 -alkyl)amino, C3 -C6 -cycloalkyl or C2 -C6 -alkoxyalkyl, R3 is hydrogen, halogen, C1 -C5 -alkyl, C2 -C5 -alkenyl, C1 -C4 -haloalkyl, or a group --X-R6, --COZR11, --NO2 or --CO-NR8 R9, --CN, --COR10, --NR1 R7 or --NR1 -COR12, R4 is hydrogen, C1 -C4 -alkyl, C1 -C4 -alkoxy, C1 -C4 -alkylthio, C1 -C4 -haloalkyl, C1 -C4 -haloalkoxy, halogen, or alkoxyalkyl having at most 4 carbon atoms, R5 is the same as R3 but independent thereof, R6 and R7 are each C1 -C5 -alkyl, C2 -C5 -alkenyl or C2 -C6 -alkynyl, R8 and R9 independently of one another are each hydrogen, C1 -C5 -alkyl, C2 -C5 -alkenyl or C2 -C6 -alkynyl, R10 is hydrogen, C1 -C4 -alkyl or C1 -C3 -haloalkyl, R11 is hydrogen, C1 -C4 -alkyl, C1 -C3 -haloalkyl, C3 -C5 -alkenyl, C3 -C5 -alkynyl, phenyl or benzyl, and R12 is the same as R1 but independent thereof, and the salts of these compounds with amines, alkali metal bases or alkaline-earth metal bases or with quaternary ammonium bases, have good pre- and post-emergence-selective herbicidal and plant-growth-regulating properties.
