ABSTRACT
Severe root and stem base rot was noticed for the first time on Sciadopitys verticillata in 3 hardy ornamental nursery stocks. Phytophthora citrophthora was isolated from about 4/5 of the analysed plants. In the laboratory trials this species caused stem and root rot. On stem parts and needles inoculated by isolates from the host plant and Pinus sylvestris, necrosis was observed to have spread at a similar rate. The needles, however, were colonized significantly quicker than the stem parts.
