Definitions

  • the present invention relates to a method for treating wood against infestation by wood-damaging fungi.
  • fenpropimorph (4- [3- ⁇ 4-tert-butylphenyl ⁇ -2-methylpropyl] -2,6-c ⁇ s-dimethylmorpholm) is generally known (cf. DE-A 26 56 747).
  • WO-A 95/16349 discloses fungicidal mixtures and agents for crop protection containing them, which contain fenpropimorph and a tnazole compound as active substances.
  • DE-A 43 40 853 teaches a synergistic mixture for use in wood protection which, in addition to a copper compound and an alkanolamine, contains a tazole compound and a further fungicide, for example fenpropimorph.
  • Fenpropimorph, the tnazole compounds and the known synergistic mixtures which contain these active ingredients do not have a satisfactory effect against wood-damaging, wood-fungal fungi.
  • the object of the present invention was therefore to remedy this deficiency.
  • wood is also intended to include wood secondary products such as woodcuts, cellulose and other technical products or materials containing cellulose that are susceptible to fungal attack, e.g. Intermediates in papermaking and woody annual plants (bar alley, rapeseed) are included.
  • Suitable triazole compounds are: 2- (1-chlorocyclopropyl-1- (2-chlorophenyl) -3- (1,2,4-triazol-1-yl) propan-2-ol, 1-butyl-1 - (2, 4-dichlorophenyl) -2- (1,2, 4-triazol-l-yl) ethanol (hexaconazole), 1- (2-chlorophenyl) methyl) -l- (1, 1- dimethyl) -2- (1,2, 4-triazol-l-ylethanol, 1- (4-fluorophenyl) -1- (2-fluorophenyl) -2- (1,2,4-triazol-l-yl) ethanol (Flutriafol), (RS) -4- (4-chlorophenyl) -2-phenyl-2- (1H-1,2,4-triazol-l-yl-methyl) butyronitrile, 1- (2 RS, 4 RS; 2 RS, 4 SR) -4

  • the mixtures of fenpropimorph and one or more triazole compounds are generally formulated with conventional formulation auxiliaries to form wood preservatives before they are used. Liquid wood preservatives are preferably produced because of the better handling.
  • the mixture is used in such a way that the wood to be protected is treated with fenpropimorph and one or more triazole compounds simultaneously, together or separately, or in succession.
  • the mixture of fenpropimorph and one or more triazole compounds is preferably used in an amount of 0.05 to 5 kg per cubic meter of wood.
  • the mixtures used according to the invention are partly liquid. Regarding their use in wood protection, they are preferably formulated in liquid form, for example
