Abstract: A downy mildew was observed on Buddleja × weyeriana Weyer ex Rehd. (B. davidii × globosa) cv. Sungold in a nursery in the northern part of the Czech Republic in July 2008. This downy mildew disease of Buddleja (Butterfly Bush) had been unknown in the country so far. Characteristics of visual symptoms and microscopic features are described. The morphology of the fungus was typical for Peronospora hariotii, conforming to the published description by GÄUMANN (1919). The sexual stage was not found. This is the first report of Peronospora hariotii causing leaf spot disease on Buddleja in the Czech Republic.
