Box blight now present in NC and US

Posted by M.J. Munster on 29 Nov 2011
last update: 17 Jan 2012

The presence in North Carolina of box blight, caused by the fungus Cylindrocladium pseudonaviculatum, was confirmed in October 2011. This fungus has been present in Europe and New Zealand for several years, but has now made its first appearance in the USA. The only known natural hosts for this fungus are species of Buxus, and the infestation in North Carolina appears to be very limited in extent. For further details on the disease, the situation, and what to do if you suspect it in your boxwoods, see the Alert by Drs. Kelly Ivors and Anthony LeBude at http://go.ncsu.edu/boxblight. See also the guide to box blight symptoms.

NCEES and NCDA&CS personnel, please see this additional information.

Expanded range for Laurel Wilt in NC

Updated 22 February 2012

The fungus that causes laurel wilt (Raffaelea lauricola) has been confirmed for the first time in Brunswick County.  NCFS Forest Health staff found symptomatic trees in Brunswick County near Sandy Creek.  Stained wood samples were sent to the USDA Forest Service Southern Research Station Laboratory in Athens, GA, where culturing confirmed the presence of the pathogen. 

Counties in North Carolina where laurel wilt is known to be present include Bladen, Brunswick, Columbus, Pender, and Sampson (map).
