摘要 |
The invention relates to novel substituted phenyl uracils of the formula (I) in which R<SUP>1 </SUP>represents hydrogen, amino or in each case optionally substituted alkyl, alkenyl or alkynyl, R<SUP>2 </SUP>represents cyano, carboxy, carbamoyl, thiocarbamoyl or optionally substituted alkyl or alkoxycarbonyl, R<SUP>3 </SUP>represents hydrogen, halogen or optionally substituted alkyl, R<SUP>4 </SUP>represents hydrogen, nitro, cyano, alkoxy or halogen, R<SUP>5 </SUP>represents cyano, thiocarbamoyl, halogen or optionally substituted alkyl or alkoxy and R<SUP>6 </SUP>represents an optionally substituted nitrogen-containing heterocyclic group which is attached to R<SUP>6 </SUP>via N, to processes for their preparation, to their use as crop treatment agents, and to intermediates and processes for their preparation.
