This Best Management Practice document is a set of guidelines for home growers of landscape boxwood to avoid introduction of the boxwood blight pathogen into a landscape or, if the disease is already present in a landscape, to manage the disease in the most effective manner and avoid spread of the disease to new locations.

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.

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.
