Abstract

The invention relates to novel fungicidally active compound combinations of 2′-cyano-3,4-dichloroisothiazole-5-carboxanilide of the formula and active compounds listed in the disclosure.

1 . A fungicidal composition comprising an active compound combination consisting of
 (a) 2′-cyano-3,4-dichloroisothiazole-5-carboxanilide of formula (I)   
       
         
           
           
               
               
           
         
       
       and
 (b) one or more of the compounds
 (1) a neonicotinyl of formula (II-c), (II-d), or (II-g) 
 
 
       
         
           
           
               
               
           
         
         
           and/or 
           (2) a phenylpyrazole of formula (IV) 
         
       
       
         
           
           
               
               
           
         
         
           
             in which 
             (i) for fipronil (formula IV-a), R 3  is —CF 3 , 
             or 
             (ii) for ethiprole (formula (IV-b), R 3  is C 2 H 5 , 
           
         
       
       and
 (c) one or more extenders and/or surfactants. 
 
     
     
         2 . A composition according to  claim 1  wherein in the active compound combinations the weight ratio of the active compound of formula (I) to
 active compound of group (1) is between 1:0.1 and 1:100, and 
 active compound of group (2) is between 1:0.5 and 1:50. 
 
     
     
         3 . A method for controlling fungi comprising applying an effective amount of an active compound combination according to  claim 1  to the fungi and/or their habitat. 
     
     
         4 . A process for preparing a fungicidal composition comprising mixing an active compound combination according to  claim 1  with one or more extenders and/or surfactants.
