MINNESOTA DEPARTMENT OF AGRICULTURE
STATE EXTERIOR QUARANTINE
THOUSAND CANKERS DISEASE OF WALNUT (JUGLANS SP)
Section I: Statement of Concerns
Whereas, the Commissioner of the Minnesota Department of Agriculture, having found that a new and emerging disease of walnut (Juglans species) has been detected in other states and has a limited distribution at this time; and
Whereas, this disease, called Thousand Cankers Disease of Walnut, is caused by an insect/fungus complex in which the insect called the walnut twig beetle (Pityophthorus juglandis) introduces the fungus (Geosmithia morbida) into walnut trees (Juglans species) causing cankers which eventually kill the walnut tree; and
Whereas, hundreds of walnut trees in western and southwestern United States have been killed by Thousand Cankers Disease of Walnut and was confirmed for the first time on black walnut (Juglans nigra) in its native range in July 2010, in Knoxville, Tennessee; and
Whereas, black walnut is an environmentally important tree in Minnesota, with the native range of this species extending through southeastern Minnesota, and along with plantations, totals over six million trees according to US Forest Service estimates; and
Whereas, black walnut is an economically important tree in Minnesota, as it is highly valued for its wood and one to two million board feet of black walnut are harvested annually in Minnesota; and
Whereas, Thousand Cankers Disease of Walnut poses a serious threat to walnut trees in Minnesota; and
Whereas, it is necessary to protect Minnesota’s walnut timber production, the native ecosystem and walnut as a landscape species from Thousand Cankers Disease of Walnut; and
Whereas, Thousand Cankers Disease of Walnut can be spread by movement of unregulated articles into the state,
Now, therefore, the State of Minnesota is hereby establishing this emergency plant exterior quarantine by the authority of Minnesota Statutes Chapter 18G.06, subd. 5 (2010), to prevent the spread of Thousand Cankers Disease of Walnut into Minnesota and sets forth: definitions, regulated articles, conditions of movement, violations and penalties, and special exemptions. This quarantine shall become effective immediately upon signing and will remain in effect until rescinded by the Commissioner.
