Elm tree concerns - Dutch elm disease and European elm scale are two insect/disease problems to look out for on your elm trees this spring.
Dutch elm disease (DED) is caused by the invasive fungal pathogen, Ophiostoma novo-ulmi. It is spread by the Elm bark beetle or from tree to tree through the roots. The first sign of DED is often wilting and yellowing of leaves or branches in the outer crown of the tree. Click here for more information about DED from NDSU Extension.
European elm scale is most noticeable by the appearance of honeydew or black mold on the bark of the tree. Heavy infestations can cause premature yellowing and shedding of leaves and killing of twigs and branches. For more information on this insect, click here for an article from CSU Extension.
