Definitions

  • the present invention relates to fungicidal mixtures containing as active components
  • the invention also relates to a method for controlling harmful fungi with mixtures of the compound I with the compound II and the use of the compound I with the compound II for the production of such mixtures and agents which contain these mixtures.
