While in Kentucky this weekend I learned that Thousand Cankers Black Walnut Disease had been found in Tennessee. A few weeks ago no cases had been reported in the Eastern part of the United States.
This disease can potentially cause walnut trees in North America to become extinct.
It is not a time to give up hope for the walnut tree but it is certainly time to take action. Contact your State Department of Agriculture of University Extension for local information. Some states and counties are already banning the transport of walnut logs, firewood, etc.
Here are some link to more information:
