SUBSTITUTED PHENYLURACILS

摘要

The invention relates to novel substituted phenyl uracils of the formula (I) in which R¹ represents hydrogen, amino or in each case optionally substituted alkyl, alkenyl or alkynyl, R² represents cyano, carboxy, carbamoyl, thiocarbamoyl or optionally substituted alkyl or alkoxycarbonyl, R³ represents hydrogen, halogen or optionally substituted alkyl, R⁴ represents hydrogen, nitro, cyano, alkoxy or halogen, R⁵ represents cyano, thiocarbamoyl, halogen or optionally substituted alkyl or alkoxy and R⁶ represents an optionally substituted nitrogen-containing heterocyclic group which is attached to R⁶ via N, to processes for their preparation, to their use as crop treatment agents, and to intermediates and processes for their preparation.
