The combination of the plant microbicide 4-(2,2-difluoro-1,3-benzodioxol-7-yl)-1H-pyrrole-3-carbonitril with the plant microbicide .alpha.-[2-(4-chlorophenyl)ethyl]-.alpha.-(1,1-dimethyl-ethyl)-.beta.-(1H- 1,2,4-triazolyl)-1-ethanol results in a synergistically enhanced effect in the control of plant diseases. Microbicidal compositions based on such combinations are suitable for treating natural products of vegetable and animal origin and, in particular, for seed treatment.

Microbicidal compositions

The combination of the plant microbicide 4-(2,2-difluoro-1,3-benzodioxol-7-yl)-1H-pyrrole-3-carbonitrile with the plant microbicide 1-{2-[2-chloro-4-(4-chlorophenoxy)phenyl]-4-methyl-1,3-dioxolan-2-ylmethyl }-1H-1,2,4-triazole results in a synergistically increased effect in the control of plant diseases. Microbicidal compositions based on such combinations are suitable for treating crops of plants and natural products of vegetable and animal origin, and for seed treatment.

The combination of the plant microbicide 3-cyano-4-(2,3-dichlorophenyl)-pyrrole ('fenpiclonil') with the plant microbicide 1-(1H-1,2,4-triazol-1-yl)-2-methoxy-2-[4-(4-chlorophenoxy)-2-chlorophenyl] -butane results in a synergistically enhanced activity in the control of plant diseases. Plant microbicidal compositions based on such combinations are especially suitable for treating seed.
