Widespread Phytophthora infestations in European nurseries put forest, semi-natural and horticultural ecosystems at high risk of Phytophthora diseases
An analysis of incidence of Phytophthora spp. in 732 European nurseries producing forest transplants, larger specimen trees, landscape plants and ornamentals, plus 2525 areas in which trees andExpand

Conifer seedling root fungi and root dieback in Finnish nurseries
Fungi were isolated from the roots and growth substrate of bare‐rooted and containerized Pinus sylvestris and Picea abies nursery seedlings displaying a root dieback. Isolations were also made fromExpand

Genetic variation and host specificity of Phytophthora cactorum isolated in Europe
Analysis of Phytophthora cactorum using Random Amplified Microsatellites (RAMS) revealed considerable variation among isolates, most of which correlated with the original host plants. The lack ofExpand

Anamorphic and teleomorphic characteristics of a uninucleate Rhizoctonia sp. isolated from the roots of nursery grown conifer seedlings
Vegetative, anastomosis, fruiting and basidial characteristics were analysed in one Norwegian and five Finnish Rhizoctonia isolates from the roots of various nursery grown conifer seedlings. TheExpand

The occurrence and pathogenicity of uni- and binucleate Rhizoctonia and Pythiaceae fungi among conifer seedlings in Finnish forest nurseries
Uni- and binucleate Rhizoctonia and Pythiaceae fungi were isolated from roots of dieback seedlings. Only binucleate Rhizoctonia strains were present in the roots of healthy seedlings. InExpand

First record of Chalara fraxinea in Finland and genetic variation among isolates sampled from Åland, mainland Finland, Estonia and Latvia
Summary We have isolated and confirmed the identification of ash dieback fungus (Chalara fraxinea, teleomorph Hymenoscyphus albidus) for the first time in Finland. In a preliminary analysis,Expand

Effect of uninucleate Rhizoctonia on Scots pine and Norway spruce seedlings
Summary One-year-old container-grown seedlings were planted in spring on clear cut areas: the Norway spruce (Picea abies) on a moist upland site (Myrtillus-type) and Scots pine (Pinus sylvestris)Expand
