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.
