Mixtures of certain triazole fungicides (component I) and 4-cyclopropyl-6-methyl-N-phenyl-2-pyrimidinamine (component II) have a synergistically increased activity against fungus infestation. Components I and II can also be applied to crops individually in immediate succession.

Compositions and methods of combatting fungi employing triazoles and a

Microbicides

The combination of the plant microbicide 1-[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-ylmethyl]-1H-1,2,4-triaz ole (=propiconazole) with the plant microbicide 1-{2-[2-chloro-4-(4-chlorophenoxy)-phenyl]-4-methyl-1,3-dioxolan-2-ylmethy l}-1H-1,2,4-triazole results in an increased activity in the control of plant diseases. Plant microbicidal compositions based on such combinations are suitable especially for controlling diseases in cereals.
