Kartlegging
Kartlegging av Phytophthora langs Sørkedalsvassdraget 2019
In a survey in the vally of Sørkedalen in Oslo in 2019, four Phytophthora species were detected from water/mud/leaves in the main waterways; P. gonapodyides, P. lacustris, P. plurivora and Phytophthora taxon raspberry. The three former species were also detected in the same valley in 2018 and they have all been found earlier in Norway. However, Phytophthora taxon raspberry was new to Norway. No Phytophthora species were isolated from diseased trees, but typical Phytophthora symptoms were observed on several locations of grey alder (Alnus incana). Phytophthora lacustris was also confirmed from water reservoirs in a fish hatchery
