| 摘要 |
The invention relates to N-azidophenylsulfonyl-N'-pyrimidinyl- and -N'-triazinylureas of the general formula <IMAGE> wherein E is nitrogen or the methine bridge, R1 is hydrogen, halogen, nitro, C1-C4alkyl, C1-C4haloalkyl, C1-C4alkoxy, C1-C4haloalkoxy, C1-C4alkoxycarbonyl, C1-C4alkylthio, C1-C4alkylsulfinyl, C1-C4alkylsulfonyl or C2-C5alkoxyalkoxy, R2 is C1-C3alkyl, C1-C3alkoxy or C1-C3haloalkoxy, R3 is hydrogen, halogen, C1-C3alkyl, C1-C3haloalkyl, C1-C3alkoxy, C1-C3haloalkoxy, C2-C5alkoxyalkoxy or -NR4R5, wherein R4 is hydrogen or methyl and R5 is hydrogen, methyl, ethyl or methoxy and to the salts thereof with amines, alkali metal hydroxides and alkaline earth metal hydroxides or with quaternary ammonium bases. These compounds have good pre- and postemergence selective herbicidal and growth regulating properties.
