Phytophthora (Greek for `plant destroyer') is one of the world's most destructive genera of plant pathogens. In the early 1990s concern about the increasing impact of invasive and endemic Phytophthoras on tree health led to the formation of a new IUFRO Working Group, Phytophthora pathogens of trees in forests and natural ecosystems.
Progress in Research on Phytophthora Diseases of Forest Trees is the third in a series of conference proceedings from the Working Group. The conference brought together a range of specialist scientists to exchange information on the threat Phytophthora species pose to trees, including oaks, alders, beech, chestnuts, cedars, pines, eucalypts and rhododendrons.
