title: Phytophthora spp. associated with nursery reservoirs, rivers and drainage canals.
abstract: Phytophthora spp. were recovered from water using rhododendron leaves as baits for detection of that group of organisms. They were was found in 4 rivers, 2 hardy nursery water reservoirs and nursery drainage canal from May to October, 2006. Analysis of spots number on rhododendron leaf baits as the measure of Phytophthora spp. density showed that place of baits holding had significant influence on the species occurrence. Significantly more spots, especially in July surveying, were observed on baits holding in Skierniewka and Zwierzynka rivers swimming through agriculture and forest area than in Ner, the river of horticulture area. In nursery water containers and drainage canal higher Phytophthora density was noticed on August than other periods of surveying.
