Boxwood Blight

First identified in the United Kingdom in the mid-1990's, it has also been confirmed from New Zealand and across Europe. The first detection in the US occurred late fall 2011, with detections in North Carolina, Connecticut, and Virginia.

Since those initial detections, this disease has continued to spread. There have not yet been any reports of boxwood blight from New Hampshire. The nursery industry and customers growing boxwoods should, however, be aware of and on the lookout for this new disease. Please see Boxwood blight information sheetpdf file for more information on symptoms, life history, susceptible hosts, and suggested management of this disease. Please contact the Division if you believe you have nursery stock or landscape boxwoods infested with boxwood blight.

You can submit plant samples for identification of boxwood blight to the University of New Hampshire Plant Diagnostic Lab.
