Definitions

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