Phytophthora ramorum is a foliage/shoot blight and stem canker. It is an oomycota pathogen and was first described in 2001 as a disease of Rhododendron spp., Viburnum spp. and Pieris spp from Germany and the Netherlands. However, the disease caused by this pathogen had been observed since 1993 (Werres et al., 2001). It is commonly referred to as Ramorum dieback or Sudden Oak Death. In the USA, P. ramorum has caused the mortality of oaks (mainly tanoak and coast live oak) in native forests and the urban-native forest interface in the coastal fog belts of southern Oregon and northern California since 1994 (Figure 1) ('Sudden Oak Death' Rizzo et al., 2002).
