| 摘要 |
The invention relates to N-phenylsulfonyl-N'-pyrimidinylureas and N-phenylsulfonyl-N-triazinylureas of the general formula <IMAGE> (I) wherein Q is selected from a radical <IMAGE> +TR <IMAGE> Z is oxygen or sulfur, E is nitrogen or =CH-, R2 is hydrogen, C1-C4 alkyl or C1-C3 alkoxy, and R3 and R4, each independently of the other, are hydrogen, C1-C4 alkyl, C1-C4 alkoxy, C1-C4 haloalkoxy, C1-C4 haloalkylthio, C1-C4 alkylthio, halogen, C2-C5 alkoxyalkyl, C2-C5 alkoxyalkoxy or -NR5R6, wherein R5 and R6 are hydrogen or C1-C4 alkyl, and to the salts of these compounds with amines, alkali metal bases or alkaline earth metal bases or with quaternary ammonium bases. These compounds have good pre- and postemergence selective herbicidal and growth regulating properties.
