Minnesota Limits Walnut Wood Imports

Walnut wood is no longer allowed into Minnesota if it comes from 11 states with thousand cankers disease.

Agriculture Commissioner Dave Frederickson announced the quarantine to prevent the disease from entering Minnesota. It is caused by a fungus carried by the walnut twig beetle.

The disease has been found in Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Tennessee, Virginia, Washington and Utah.
