摘要：
3-Aryluracils of the formula I wherein A is hydrogen, methyl or amino; X is oxygen or —N(R7)— (R7=H alkyl, alkenyl, alkynyl, alkylcarbonyl or alkoxyalkyl); Y1 is oxygen or sulfur; Z is oxygen or —N(R8)— (R8=H, alkyl, alkenyl, alkynyl or alkoxyalkyl); R1 is hydrogen or halogen; R2 is hydrogen, halogen, alkyl, haloalkyl, alkylthio, alkylsulfenyl or alkylsulfonyl; R3 is hydrogen, halogen or alkyl; R4 is hydrogen; or optionally substituted alkyl, cycloalkyl, haloalkyl, alkenyl, alkynyl, alkylcarbonyl, alkenylcarbonyl, alkynylcarbonyl or alkylsulfonyl, R5, R6 are hydrogen, alkyl, alkenyl, alkynyl or alkoxyalkyl; or R6, R8 are together a second chemical bond, methods and intermediates for their manufacture, and their use as herbicides or for the desiccation or defoliation of plants.
