Herbicidal sulfonylureas Abstract Substituted N-arylsulfonyl-N'-pyrimidinylureas and N-arylsulfonyl- N'-triazinylureas of the general formula Image (I), wherein R1 is a Image radical, R2 is hydrogen, halogen, nitro, C1-C3alkyl, C1-C3alkoxy or -COOR9, R3 is hydrogen, C1-C3alkyl or C1-C3alkoxy, R4 and R5 are each independently of the other hydrogen, halogen, C1-C4alkyl C1-C4haloalkyl, C1-C4alkoxy, C1-4 C1-C4alkylthio, C1-C4haloalkylthio, C2-C4alkoxyalkyl, C3-C6- cycloalkyl or -NR10R11, R6 is hydrogen or C1-C3alkyl, R7 is hydrogen or methyl, R8 is C4-C6cycloalkanoyl which is unsubstituted or substituted by C1-C3alkyl or halogen; C3-C6cycloalkyl which is unsubstituted or substituted by one or more identical or different members selected from the group consisting of C1-C3alkyl, C1-C3alkoxy, halogen or cyano; or is C5-C6cycloalkenyl which is unsubstituted or substituted by C1-C3alkyl, halogen or cyano, R9 is C1-C3alkyl or allyl, R10 and R11 are each independently of the other hydrogen or C1-C4alkyl, n is 0 or 1, X is sulfur or oxygen, and E and Z are each independently of the other nitrogen or the methine bridge, with the proviso that R8 is only unsubstituted or substituted C3-C6cycloalkyl if at the same time Z is nitro- gen, and the salts of these compounds with amines, alkali metal bases or alkaline earth metal bases, have good pre- and postemergence selctive herbicidal and growth regulating properties.
