Boxwood blight, caused by Cylindrocladium buxicola, is an emerging disease of boxwood (Buxus). After Europe and New Zealand, it is now invading North America. It was first recorded in USA at the end of 2011 in Connecticut, North Carolina and Viriginia. By mid-January 2012, the fungus has been found in at least five more states in the USA — Virginia, Maryland, Rhode Island, Massachusetts and Oregon — and in British Columbia in Canada.
