CA 2645606

The invention relates to aqueous suspension concentrates containing (1) one or more active substances from the group of the herbicidally active 2,4-diamino-s-triazines which are N-substituted at one amino group by a (hetero)aryl(hetero)alkyl group, (2) one or more active substances from the group of herbicidally active phosphate-containing derivatives of the amino acids glycine/homoalanine, (3) one or more surfactants which are based on substituted phenol ethers of the nonsalt type, (4) one or more thickeners, preferably thickeners based on aluminosilicates, and (5) if appropriate further formulation adjuvants, and (6) if appropriate other surfactants which are different from component (3). Not only is a high stability of the active substances in the formulations achieved, but also an improved biological activity while keeping the application rate constant.
