Butternut (Juglans cinerea L.)

Information on butternut and the butternut canker in Canada

Butternut canker attacks and kills butternut trees of all ages and sizes and on all sites. The fungus (Sirococcus clavigignenti-juglandacearum) attacks the inner bark of the tree and causes cankers. Cankers spread around the branches and trunk from season to season, girdling the tree and eventually killing it.

Butternut canker has become a serious threat to the survival of butternut across North America. The species has all but disappeared in many parts of the U.S.A. and is under threat in Ontario, Quebec, and New Brunswick.
