The invention relates to novel substituted phenyl uracils of general formula (I), wherein A represents alkanediyl or alkenediyl, optionally substituted with cyano, halogen or C1-C4-alkyl, C1-C4-alkoxycarbonyl or C2-C4-alkenyl, optionally substituted with halogen or C1-C4-alkoxy; or interrupted with O (oxygen), with 2 to 5 carbon atoms, respectively, or cyclohexane-1,2-diyl or 1,2-phenylene; Q1 represents O (oxygen) or S (sulphur); Q2 represents O (oxygen) or S (sulphur); R1 represents hydrogen, amino or alkyl, optionally substituted with cyano, halogen or C¿1?-C4-alkoxy, with 1 to 4 carbon atoms; R?2¿ represents alkyl substituted with halogen and with 1 to 4 carbon atoms; R3 represents hydrogen, halogen or alkyl, optionally substituted with halogen and with 1 to 4 carbon atoms; R4 represents hydrogen, cyano, carbamoyl, thiocarbamoyl or halogen; R5 represents cyano, carbamoyl, thiocarbamoyl or alkyl or alkoxy, optionally substituted with halogen and with 1 to 4 carbon atoms, respectively; and R6 represents hydrogen or alkyl with 1 to 4 carbon atoms. The invention also relates to a method for producing the inventive phenyl uracils and to their use as herbicides.
