CHARLESTON, W.Va. (AP) -- West Virginia has declared a quarantine to prevent thousand cankerous disease from killing walnut trees in the state.
The Department of Agriculture said Thursday that the quarantine went into effect May 20.
Plant Industries Division director Sherri Hutchinson says no walnut plants or plant parts from Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah and Washington can be brought into West Virginia or moved through the state. The quarantine also applies to areas of any state where the disease has been found.
The quarantine includes any hardwood firewood from infected areas, the fungus that causes the disease, and the walnut twig beetle, which infects trees with the disease.
Nuts, nut meats, processed lumber and finished wood products such as furniture are exempt from the quarantine.
