Express PRA for Raffaelea canadensis - Research and Breeding -
The Ambrosia fungus Raffaelea canadensis presumably is endemic to North America and according to current knowledge, it does not occur in Germany. The only known occurrence in Europe is in Portugal. So far, it is listed neither in the Annexes of the Regulation (EU) 2019/2072 nor by EPPO..
So far, R. canadensis was detected in conifers, avocado plants and cork oaks. There was an indication on potential damage by the fungus once on an avocado tree in California and in cork oaks in Portugal. It is currently still unclear whether the fungus should actually be regarded as the causative agent of a plant disease.
According to the current state of knowledge, the damage potential of R. canadensis is low and it poses no phytosanitary risk for Germany and other EU-Member States.
