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.

Invasive insect pests and diseases are threatening the future forests of Virginia. The transport of firewood is one of the primary means by which these harmful insects and diseases spread. Quarantines have been issued by the Virginia Department of Agriculture and Consumer Services to restrict the movement of firewood from counties where the pests have been found to counties without them.
