Phytophthora citricola was isolated fromdiseased seedlings of European beech and Silver fir taken fromthe most of surveyed nurseries. Fusarium species, Pythium ultimum and Rhizoctonia solani were also found in diseased plant tissues. Isolates of P. citricola fromboth plants and additionally fromheather and rhododendron colonised leaf blades, needles and stemparts of beech and fir. In greenhouse trials on inoculated 1-year-old seedlings necrosis spread about 2 mm/24 hr on beech stems whereas on fir about 1.5 mm/24 hr.

Gatunek Phytophthora citricola izolowano z większości szkółek leśnych buka i jodły z objawami zgnilizny korzeni i podstawy pędu. Obok tego patogena z porażonych tkanek wyosobniano inne grzyby patogeniczne z rodzaju Fusarium oraz Pyhtium ultimum i Rhizoctonia solani. Izolaty P. citricola z buka i jodły oraz z wrzosa i różanecznika kolonizowały liście i igły oraz części łodyg buka i jodły. W doświadczeniu szklarniowym, na zakażonych u nasady 1-rocznych siewkach nekroza rozwijała się około 2 mm/dobę na buku i 1,4 mm na jodle.
