First confirmation of Phytophthora lateralis in Europe
Plant Disease 83 (6), 587-587
Abstract: Port-Orford cedar or Lawson's cypress (Chamaecyparis lawsoniana) can be infected with Phytophthora lateralis in western North America. The disease is now also confirmed in France on young, potted, greenhouse-propagated cedars in a commercial nursery. The identification was based on morphological characteristics and ITS sequence analysis. Pathogenicity of isolates from France and Oregon was demonstrated by inoculation. P. lateralis has been also reported from Germany. However, these isolates were identified as P. gonapodyides based on morphological characteristics and ITS sequence analysis.
