For centuries, the vine was produced in the Tokay region. Acreages and vine varieties convenient to growing (cv. Lipovina, cv. Yellow Muscat, cv. Furmint) are strictly concluded by the legislation. Due to the monocultures and low intervarietal diversity, better conditions for more aggressive manifestation of pathogens have been formed. During 2005-2008 there were observed the occurrences of grapevine downy mildew Plasmopara viticola (Berk and Curt.) Berk. and DeToni in listed varieties and in selected experimental sites with different altitude. At the same time the influence of microclimatic factors and bush structure on extension and occurrence of grapevine downy mildew was observed. According to our experimental observations and results the most vulnerable time period in connection with grapevine downy mildew infection is the BBCH 68 phenophase. Even though several handbooks describe the etiology of the disease outbreak and course they do not describe some possible changes of pathogenic fungus in relation to host plant or environment. Based on our research results an integrated vine protection was proposed.
