This concise publication gives useful information for homeowners, master gardeners, and professional landscapers about the boxwood blight disease: its symptoms, sanitation measures when it is discovered on a property, and preventive measures.
New Hampshire Department of Agriculture, Markets, and Food.
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.

The emerald ash borer, a beetle pest that has devastated ash trees throughout the eastern United States, was officially detected in Greenville, Oconee and Spartanburg counties in August 2017. According to a Clemson University press release, the beetles were found Aug. 3 during a routine check of Emerald Ash Borer traps and confirmed by the U.S. Department of Agriculture. In response to the discovery of EAB in the Upstate, the State Crop Pest Commission likely will establish a quarantine area involving at least the three affected counties; it is also possible the quarantine could be expanded to additional counties or even the entire state.

Mississippi's ash trees are living on borrowed time. Every day the emerald ash borer is not detected in Mississippi is a minor victory. Infestations in surrounding Tennessee (detected 2010 near Nashville), Arkansas (detected in 2014 near Hot Springs) and north-central Louisiana (2015) continue to expand, despite quarantines in those areas. Most frighteningly, EAB was confirmed in Calhoun County, Alabama in October 2016. EAB now has Mississippi surrounded, and it is likely only a matter of time before it finds its way here. To prevent the spread of this and other non-native beetles, do not move firewood. Firewood is a vehicle for movement of tree-killing forest pests including EAB and Asian longhorned beetle. See Forest Health Articles for more pest alerts.
