Case 5-13594/= N-Phenylsulfonyl-N'-pyrimidinyl- and -triazinylureas Abstract N-phenylsulfonyl-N'-pyrimidinyl- and -triazinylureas of the general formula Image and the salts of these compounds with amines, alkali metal or alkaline-earth metal bases or with quaternary ammonium bases have good selective, pre- and post-emergence, herbicidal and growth-regulating properties. The symbols in this formula have the following meanings: A is a C3-C6 alkynyl group, a C1-C6-alkyl group which is substituted by halogen, C1-C4-alkoxy, C1-C4-alkylthio, C1-C4-alkylsulfinyl, C1-C4-alkylsulfonyl, C1-C4- haloalkoxy, C1-C4-haloalkylthio, C1-C4-haloalkyl- sulfinyl or C1-C4-haloalkylsulfonyl, or it is a C2-C6-alkenyl group substituted by one of the above substituents, E is the methine group or nitrogen, X is oxygen, sulfur, or a sulfinyl or sulfonyl bridge, Z is oxygen or sulfur, m is the number one or two, R1 is hydrogen, halogen, C1-C5-alkyl, C2-C5-alkenyl, or a -Y-R6 group, R2 is hydrogen, halogen, C1-C5-alkyl, C2-C5-alkenyl or C1-C4-haloalkyl, or a group -Y-R6, -COOR7, -NO2 or -CO-NR8-R9, R3 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, R4 is hydrogen, methyl or ethyl, R5 is hydrogen, C1-C4-alkyl, C1-C3-alkoxy, methoxy- methyl, cyanomethyl or cyanoethyl, 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, and Y is oxygen, sulfur, or a sulfinyl or sulfonyl bridge, and A can also be C2-C6-alkenyl when X is oxygen.
