New hosts of Pseudoperonospora cubensis in the Czech Republic and pathogen virulence variation

Popis výsledku v původním jazyce

During the 2009, 2010, and 2011 growing seasons, disease prevalence and severity and the host range of Pseudoperonospora cubensis, the causal agent of cucurbit downy mildew, were evaluated at more than 70 locations in two main regions of the Czech Republic (CR). Infection by P. cubensis was observed primarily on Cucumis sativus and medium to high disease-severity levels prevailed. During the years 2010 and 2011, P. cubensis infection was also recorded on other cucurbit plants: Cucumis melo, Citrullus lanatus, Cucurbita spp. (C. moschata, C. pepo, C. maxima, C. ficifolia) and Lagenaria siceraria. Occurrence of P. cubensis on C. melo and C. lanatus has been formerly reported from the CR, however, infection on C. moschata was observed for the first time in the CR in 2009. Virulence structure and its temporal changes (2010 to 2011) were studied in populations of seventy P. cubensis isolates originated from the CR. There were found the substantial changes in the pathogen virulence structure
