N-aryl-uracils based Herbicides

Abstract

The invention relates to novel herbicidal active compound combinations which comprise, on the one hand, known N-aryl-uracils and, on the other hand, known herbicidally active compounds and/or compounds which improve crop plant compatibility, which combinations can be used with particularly good results for controlling monocotyledonous and dicotyledonous weeds in various crops of useful plants, but also for controlling monocotyledonous and dicotyledonous weeds in the semi- and non-selective area.
