Abstract

Active compound mixtures comprising ipconazole and at least one further fungicidally active compound are highly suitable for protecting industrial materials against colonization and destruction by microorganisms.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention [0001]
  • The present invention relates to synergistic active compound mixtures comprising ipconazole and at least one further fungicidally active compound, microbicidal compositions based on these active compound mixtures and the use of these active compound mixtures, as well as compositions for protecting industrial materials. [0002]
  • 2. Brief Description of the Prior Art [0003]
  • From the literature, it is known that ipconazole has fungicidal properties and can be used for protecting industrial materials (cf. EP-A 341954). However, in protecting wood and wood composites, the antifungal action of ipconazole has been found to be insufficient against all wood-destroying organisms. Accordingly, it is an object of the present invention to improve the activity of ipconazole in the protection of industrial materials, in particular wood and wood composites. [0004]
  • Surprisingly, it has now been found that mixtures of ipconazole with certain other fungicides have better microbicidal activity, in particular against wood-destroying organisms, compared with the activity of the sum of the individual active compounds. [0005]
    • SUMMARY OF THE INVENTION
  • Accordingly, the present invention provides novel active compound mixtures comprising [0006]
  • a) ipconazole of the formula (I) [0007]
    Figure US20040138217A1-20040715-C00001
  • and [0008]
  • b) at least one further fungicidally active compound. [0009]
  • As can be seen from formula (I), the compounds of formula (I) can be present in the form of different stereoisomers. Accordingly, the present invention encompasses mixtures comprising the isomerically pure or isomerically enriched compounds of the formula (I) or the enantiomerically pure or enantiomerically enriched compound of the formula (I) or the racemate of the formula (I).[0010]
