Minnesota Restricts Walnut Tree Imports

Minnesota Agriculture Commissioner Dave Frederickson has restricted the import of walnut trees and some related products from areas infested with thousand cankers disease.

A fungus carried by the walnut twig beetle causes the tree-killing disease in Arizona, California, Colorado, Idaho, New Mexico, Oregon, Tennessee, Washington and Utah.

“This targeted quarantine will help prevent the loss of millions of trees and avoid damage to a valuable segment of our state’s forestry industry,” Frederickson said.
