Project Title: Research on necrotrophic phytophthoras of economically important broadleaved trees (QH71273)
Key words: Phytophthora sp. - necrotrophic pathogens - broadleaved trees - conservation measures - tha Czech Republic
State funding provider: Ministry of Agriculture,
Principal investigator: Mgr. Karel Černý,
Project period: 2007–2011.
The species diversity of Phytophthora pathogens in important broadleaved tree hosts in the Czech Republic was assessed and a key for their identification created. The disease symptoms were described and basic host preferences established, and a summary of control measures drawn up. 16 Phytophthora taxa were isolated from 20 host woody plant species (e.g., P. alni, P. cactorum, P. cinnamomi, P. citrophthora, P. gallica, P. gonapodyides, P. lacustris, P. megasperma, P. multivora, P. plurivora, P. ramorum, P. taxon oaksoil). The most important problems identified were: the high diversity of Phytophthora pathogens in general and their extensive distribution, the widespread distribution and importance of P. plurivora in particular, in a whole range of ecosystems and wooded areas, and the rapid invasion of many pathogens along with their (often ornamental) plant hosts and their uncontrolled spread within the Czech Republic.
