ABSTRACT
Phytophthora citricola was isolated from diseased seedlings of European beech and Silver fir taken from the most of surveyed nurseries. Fusarium species, Pythium ultimum and Rhizoctonia solani were also found in diseased plant tissues.Isoates of P. citricola fro mboth plants and additionally from heather and rhododendron colonised leaf blades, needles and stem parts 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
