The emerald ash borer is a federally regulated pest, which means its detection will trigger specific regulations that are designed to help prevent its man assisted spread. The USDA, GA Dept. of Agriculture and GA Forestry Commission have been working together to ensure that the regulations minimally impact businesses but at the same time, will limit the likelihood emerald ash borer will be moved in ash nursery stock, or in logs, mulch, firewood, and other similar items.

Although not yet detected here, thousand cankers disease (TCD) is a potentially fatal disease of black walnut, caused by the walnut twig beetle (Pityophthorus juglandis) and an associated fungus (Geosmithia morbida). TCD could easily spread to Missouri from the several eastern and western states where TCD is already present. You can help minimize the chances of spreading TCD by following these steps:

Thousand cankers disease (TCD) is a disease complex native to the western United States and primarily affects black walnut, Juglans nigra. This disease is the result of the combined activity of a fungus, Geosmithia morbida, and the walnut twig beetle WTB), Pityophthorus juglandis. On January 12, 2015, the the Maryland Secretary of Agriculture issued a quarantine order to minimize the risk of moving infested material out of the limited action area in Cecil County, and to provide confidence in Maryland walnut products moving into neighboring states from non quarantined areas. The 2015 quarantine order has been updated to include all of Baltimore City and part of Baltimore County (PDF | 1.2 MB). The new quarantine (PDF | 1.0 MB) was signed on May 1, 2019 by the Maryland Secretary of Agriculture.
