Boxwood blight (also called "box blight" in Europe), caused by the fungal pathogen Cylindrocladium pseudonaviculatum (=C. buxicola), was found for the first time in the United States in North Carolina, Virginia and Connecticut in 2011. The first reported infestation in the U.S. was in a North Carolina nursery and the disease was introduced to Virginia on plants from that nursery. Spread outside the two Virginia locations, both of which are fields owned by a single nursery, has not been reported. However, growers should be aware of the symptoms of boxwood blight and monitor nursery and landscape boxwoods for symptoms.

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:

Virginia Tech researchers who helped identify the dangerous Giant Hogweed plants in Clarke County, Virginia, want residents to stay on the lookout for the plant with toxic sap that can cause severe burns — but also stressed that the weeds are believed to have been planted intentionally decades ago and haven’t spread in the years since. Anyone who suspects they have found Giant Hogweed should take photos, check online to compare the plant to giant hogweed photos, and then contact a Virginia Cooperative Extension agent.

Northern snakeheads (Channa argus), an invasive fish, have recently been confirmed in Delaware waters. Three adult snakeheads were collected from the Delaware portion of the Nanticoke watershed: Broad Creek in Laurel, Nanticoke Branch upstream of Seaford, and the Marshyhope at Woodenhawk. The Fisheries Section asks that any possible snakehead catches in any Delaware waters be reported by emailing a photograph and details to edna.stetzar@state.de.us

Wavyleaf basketgrass is a new exotic grass rapidly moving into forests and meadows in Virginia and Maryland. The Piedmont Environmental Council is part of a Task Force committed to stopping this plant before it forms a thick carpet on our forest floors, crowding out native plants.
