Silber-Ahorn
Eutypella canker infects many species of maple trees, most prevalently the sugar maple ("Acer saccharum"). Others commonly affected are the red maple ("Acer rubrum"), box elder ("Acer negundo"), striped maple ("Acer pensylvanicum"), Norway maple ("Acer platanoides"), sycamore maple ("Acer pseudoplatanus"), silver maple ("Acer saccharinum"), and black maple ("Acer nigrum"). Onset usually occurs with greater probability of younger maples since they are more susceptible.
