    Description

    In preliminary studies on the susceptibility of plant members of the holm oak (Quercus ilex) forest, detached leaves of several woody species were highly susceptible when inoculated with zoospore suspensions of local isolates of Phytophthora ramorum (Moralejo and Hernández 2002). Since then, there have been reports of natural infections by P. ramorum on leaves and shoots of Q. ilex in the UK, and new findings on Viburnum tinus in nurseries across Europe. Taken together, this indicates that at least some areas of Mediterranean vegetation with a prevalence of the Arbutus unedo-Viburnum tinus-Quercus ilex association should be closely monitored. Yet, there are, so far, no outdoor infections in the Mediterranean basin.
