Fungicidal active compound combinations

Abstract

The novel active substance mixtures of   A) 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)- butan-2-ol of the formula <IMAGE> and/or 1-(4-phenylphenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-ol of the formula <IMAGE> and   B) 4-(2,2-difluoro-1,3-benzodioxol-7-yl)-1H-pyrrole-3-carbonitrile of the formula <IMAGE> are distinguished by very good fungicidal properties.

What is claimed is: 
     
       1. A fungicidal composition comprising a synergistic fungicidally effective amount of an active compound combination of A) at least one of 1-(4-chlorphenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)butan-2-ol of the formula ##STR15## and 1-(4-phenyl-phenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-ol of the formula ##STR16## and B) 4-(2,2-difluoro-1,3-benzodioxol-7-yl)-1H-pyrrole-3-carbonitrile of the formula ##STR17## wherein the synergistic weight ratio of (A) to (B) is between .[.1:11.]. .Iadd.1:0.1 .Iaddend.and 1:2.   
     
     
       2. A method of combating fungi which comprises applying to such fungi or to a fungus habitat a fungicidally effective amount of an active compound combination according to claim 1. 
     
     
       3. A composition according to claim 1, wherein (A) is (I). 
     
     
       4. A composition according to claim 1, wherein (A) is (II). 
     
     
       5. A composition according to claim 1, wherein (A) is a mixture of (I) and (II). 
     
     
       6. A composition according to claim 1.Iadd., .Iaddend.wherein the weight ratio of (A) to (B) is 1:1. .Iadd.7. A composition according to claim 1, wherein the weight ratio of (A) to (B) is between 1:1 and 1:2. .Iaddend.
