<p>N-(Cyclopropyl-triazinyl- and -pyrimidinyl-N'-(aryl-sulfonyl) ureas having herbicidal activity N-(Cyclopropyl-triazinyl- and -pyrimidinyl)-N'-aryl-sulfonyl ureas of the formula < IMG > (I) wherein Ar is a phenyl group < IMG > or a naphthyl group < IMG > 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-NR8R9, -CN, -COR10, -NR1R7 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 postemergence-selective herbicidal and plant-growth-regulating properties.</p> |
