Boxwood blight found in Georgia

Boxwood or Box Blight, caused by the  fungus, Cylindrocladium pseudonaviculatum  (syn. Cylindrocladium buxicola and  Calonectria pseudonaviculatum) has been confirmed in two residential landscapes in the Buckhead area of Atlanta. The source of the introduction to one of the landscapes is unknown as new boxwood plants were not introduced into the landscape. The spores of the pathogen are very sticky and it is possible that the disease was introduced on worker’s tools or clothing. Plants within the second landscape were newly introduced from NC. Once introduced, the disease can be devastating to boxwood in landscapes and nurseries.

To learn more about the symptoms and prevention of this disease, see the Georgia pest alert.

New Boxwood Disease Found in Southeast

Boxwood blight (also called “box blight” in Europe), caused by the fungal pathogen Cylindrocladium buxicola, was reported for the first time in the U.S. at two North Carolina production nurseries in October, 2011. Boxwoods originating from an infected block of plants at one of the North Carolina nurseries were planted in two production fields in Virginia. The Virginia Department of Agriculture and Consumer Services and the North Carolina Department of Agriculture and Consumer Services are developing and implementing mitigation strategies aimed at aggressively removing the pathogen from infested fields and stopping the spread of this disease.
