Title: Phytophthora ramorum

Author: Parke, J. L.; Rizzo, D. M.;

Date: 2011

Source: Forest Phytophthoras 1(1). 10 p. [early view]

Publication Series: Scientific Journal (JRNL)

Description: P. ramorum Werres, De Cock, & Man in't Veld (2001) appears to be an exotic species introduced from an unknown origin to Europe and western N. America in the mid-1990s, likely on nursery plants (Mascheretti et al. 2008). In California and southwest Oregon, the pathogen spread to native oak and tanoak forests, where it causes lethal stem cankers ('sudden oak death&339;). More than a million trees have been killed (Meentemeyer et al. 2011). In Europe, where nurseries in over 20 countries reported P. ramorum, the disease on trees was limited to isolated stands of beech and oak associated with infected rhododendrons. In 2009, the pathogen began causing widespread mortality on Japanese larch timber plantations in the UK (Brasier & Webber 2010). International, national, state and county quarantines are in place to prevent the further spread of disease with nursery plants and to contain the infestation in forests. P. ramorum is unusual among forest Phytophthora species for its wide host range and infection of aerial plant parts.

Keywords: Phytophthora ramorum, forest Phytophthora, sudden oak death
