Abstract

Herbicides containing at least one substituted pyrido[2,3-d]pyrimidine I ##STR1## or a plant-tolerated salt of those compounds I in which at least one of the substituents R.sup.1 to R.sup.5 is an acidic or a basic group, PA1 and at least one herbicidal active ingredient selected from PA2 A) the group consisting of the cyclohexenone derivatives II, or PA2 B) the group consisting of the 2-(heteroaryloxy)- or 2-(4-aryloxy)-phenoxycarboxylic acid derivative.
