Boxwood blight is a disease affecting plants in the family Buxaceae including boxwoods (Buxus), Pachysandra, and Sarcococca plants. First detected in the U.S. in 2011, it has since been found in multiple states and provinces from the East Coast to the West Coast. Boxwood blight has now been confirmed on boxwood nursery stock in New Hampshire. New Hampshire nurseries, landscapers, town officials and residents responsible for boxwood plantings should learn the symptoms associated with boxwood blight. Watch for black lesions on stems, "zonate" brown spots on leaves leading to chlorosis, and leaf drop. If boxwood blight is suspected on recently purchased boxwoods, or plants in proximity to recently purchased boxwoods, please contact the Division and collect a sample for analysis by the UNH Plant Diagnostic Lab.

To address mounting concerns over invasive plants and the role NHDOT activities play in the spread of these plants along roadsides, Best Management Practices (BMPs) have been developed with input from Maintenance Districts, the Roadside Development Section, the Bureau of Construction, and the NH Department of Agriculture. Implementation of these BMPs will help prevent the spread of invasive plants caused by maintenance and construction activities.
