This Quicksan was triggered by the description of a new nematode species, Litylenchus crenatae, that has been suggested as causal agent (or one of the causal agents) of a relatively new disease of Fagus (beach) in North America: beach leaf disease (BLD). If the nematode species is involved in BLD it is considered a serious threat for Fagus spp. in the EU. BLD nor the nematode is known to be present in the EU.
