Water-based, solvent- and emulsifier-free microbicidal active compound combination

Abstract

New microbicidal, optionally solvent- and emulsifier-free microbicidal active compound combinations and agents comprising known azole fungicides and quaternary ammonium compounds and their use in the preservation of materials.

1 . Active compound combination of at least one azole fungicide in the form of the free base and at least one quaternary ammonium fungicide.  
     
     
         2 . Active compound combination according to  claim 1 , containing at least one of the following azole fungicides: 
 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1H-1,2,4-(triadimefon)    β-(4-chlorophenoxy)-α-(1,1-dimethyl-ethyl)-1H-1,2,4-triazoles-1-ethanol    ±α-[2-(4-chlorophenyl)-ethyl]-α-(1,1-dimethyl-ethyl)-1H-1,2,4-triazole-1-ethanol    (RS)-2-(2,4-dichlorophenyl)-1-(1H-1,2,4-triazol-1-yl)-hexan-2-ol    1-(N-propyl-N-(2-(2,4,6-(trichlorophenoxy)-ethyl)-carbamoyl)-imidazole    2-(1-chlorocyclopropyl)-1-(2-chlorophenyl)-3-(1,2,4-triazol-1-yl)-propan-2-ol    -1-[[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolon-2-yl]-methyl]-1H-1,2,4-triazole (propiconazole)    1-(2-(2,4-dichlorophenyl)-1,3-dioxolon-2-yl -methyl]-1H-1,2,4-triazole (azaconazole)    and at least one quaternary ammonium fungicide formula (II)                          in which    R 1 , R 2 , R 3  and R 4  are identical or different and in each case represent unsubstituted or substituted, straight-chain or branched, saturated or unsaturated alkyl groups having 1-20 carbon atoms, alkylaryl and aralkyl groups having in each case 5-10 carbon atoms in the aryl part and 1-20 carbon atoms in the alkyl part or aryl groups having 5-10 carbon atoms, and optionally mono- or polyalkoxylated derivatives hereof; possible substituents being halogen, C 1 -C 4 -alkyl and C 1 -C 4 -alkoxy; and wherein 2 or 3 of the substituents on the quaternary centre, optionally with further hetero atoms, can form a saturated or unsaturated 5-, 6- or 7-membered (hetercyclic) ring and 
 X represents an anion which promotes water-solubility.  
   
     
     
         3 . Active compound combination according to  claim 1 , comprising tebuconazole and C 12 -C 14 -alkyl-benzyldimethylammonium halide.  
     
     
         4 . Microbicidal agents for the preservation of materials, comprising an active compound combination according to  claim 1 , solvents or diluents and if appropriate processing auxiliaries and if appropriate other active compounds.  
     
     
         5 . Microbicidal agents according to  claim 4 , comprising water.  
     
     
         6 . Microbicidal agents according to  claim 4 , for the preservation of wood and leather.  
     
     
         7 . Method of combating microorganisms, characterised in that the active compound combination according to  claim 1  is allowed to act on microbes or their habitat.
