Occurrence of Phytophthora ramorum on Rhododendron, Vaccinium, Viburnum and Quercus species in ornamental nurseris and fores stands in 2001-2002 and necrosis spead on plant parts and seedlings wewe studied. Only P. citricola was isolated from Rhododendron spp. and V.vitis-idaea. Shoot necrosis and dieback symptoms were not observed on Viburnum species in surveyed nurseries. From diseased Quercus trunks among others Armillaria spp. and Fusarium spp. were isolated. Inoculation of leaves and stem parts of Rhododendron cultivars and other ericaceous plants with P. ramorum resulted in the development of leaf and stem rot. The species caused stem necrosis of Fagus sylvatica, Q. rubra and Pseudotsuga menziesii but symptoms developed slowly
