Downy Mildew Disease

A downy mildew was observed on <I>Buddleja × weyeriana</I> Weyer ex Rehd. (<I>B. davidii × globosa</I>) cv. Sungold in a nursery in the northern part of the Czech Republic in July 2008. This downy mildew disease of <I>Buddleja</I> (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 <I>Peronospora hariotii</I>, conforming to the published description by GÄUMANN (1919). The sexual stage was not found. This is the first report of <I>Peronospora hariotii </I>causing leaf spot disease on <I>Buddleja</I> in the Czech Republic.

Downy Mildew Disease

A downy mildew disease was observed on leaves of Dianthus chinensis L. cv. Scarlet in Brno in June 2011. Characteristics of visual symptoms and microscopic features are described. The morphology of the fungus was typical of Peronospora dianthicola, conforming to the published description by Francis (1983). P. dianthicola causing leaf spots on Dianthus has been recorded for the first time in the Czech Republic.

Ramularia Leaf Spot

The fungus Ramularia collo-cygni is increasingly important as the causal agent of Ramularia leaf spot (RLS), a novel leaf spot disease of barley. The work aimed to identify gene resources suitable for developing new breeding lines of winter barley with improved resistance. During the first experimental period (2001&ndash;2005), RLS incidence was monitored in 711 cultivars and advanced breeding lines. Differences were detected in the intensity of symptomatic expression, but no material showed high resistance. During the second experimental period (2006&ndash;2009), response to natural RLS infection was evaluated in 19 winter barley cultivars (12 six-row and 7 two-row) registered in the Czech Republic. Highest susceptibility was detected in 6-row cvs. Luran, Laverda and Wendy while cvs Breunskylie (2-row), Merlot and Highlight (both 6-row) showed relatively lower disease incidence. High resistance was not detected. On average, 2-row cultivars showed lower intensity than 6-row cultivars and significant variation was observed among years.
