Eutypella-stem canker of maple - Eutypella parasitica

Symptoms / species
Impact / measures
Occurrence map

Cankers on stems of maples: initially an insignificant bark necrosis (flattened, slightly dark, sunken area with an elevated border, bark underneath dead). Winthin a couple of years this develops into a big, in the centre cracking, characteristically unilateral canker, which can cause a slight stem deformation. Fruiting bodies (perithecia) appear only after 5-8 years as blackish, brittle and flat „coverage“ at the border of the necroses in dead tissue. There are several other cankers on maple, for a serious diagnosis identification by a special lab is essential.
