Butternut Canker
Description
|
|
Butternut is being killed
throughout its range by butternut canker,
a disease that causes multiple cankers on the main stem and branches. Based
on results of surveys, the disease appears to cover practically the entire
range of butternut. Butternut, including regeneration, will be devastated
by this disease in the years to come.
