Grape Vine Downy Mildew Plasmopara viticola 

 
Grape vine downy mildew is caused by the oomycetes fungus Plasmopara viticola, which is the most disastrous vine disease. The pathogen is similar to pathogens like Phytphtora infestans, Pseudoperonospora humuli or Peronospora destructor. Grape vine downy mildew only infects vine species, like the European or American vine. Especially the European vine Vitis vinifera is most susceptible to this disease. In the nineteen century the import of this disease was the second big thread of the European vine industry after the import of Phylloxera species Viteus vitifoliae.
