Help Keep Missouri TCD-free!

Because thousand cankers disease (TCD) kills black walnut trees, it poses a serious threat to Missouri’s important black walnut industry. Fortunately, we've seen no evidence of it in our state. Early detection will be key to controlling its spread. You can help keep TCD out of Missouri by not moving firewood and other untreated walnut wood products, and by identifying and reporting early symptoms and signs of the disease. Use this information to help keep Missouri TCD-free — and our black walnut industry strong.

TCD has been detected in at least five eastern states (North Carolina, Ohio, Pennsylvania, Tennessee, and Virginia) and nine western states (Arizona, California, Colorado, Idaho, New Mexico, Nevada, Oregon, Utah, and Washington). TCD survey and detection work is ongoing.
