Definitions

• the present invention relates to fungicidal mixtures containing as active components
• the invention 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 preparation of such mixtures and compositions containing these mixtures.
• Dithianon has long been established in the market for controlling fruit and vegetable diseases caused by Alternaria, Boytis and Venfc / r / a species.
• Oomycetes differs significantly from that of the Ascomycetes, Deuteromycetes, and Basidiomycetes, as Oomycetes are biologically more related to algae than to fungi. Therefore, findings on the fungicidal activity of active compounds against "true fungi", such as Ascomycetes, Deuteromycetes, and Basidiomycetes are only very limited to Oomycetes transferable.
• Oomycetes cause economically significant damage to various crops. In many regions, Phytophthora infestans infections in potato and tomato crops are the most important plant diseases. In viticulture significant damage is caused by vine peronospora.
