Earlier this week, USDA added Cylindrocladium buxicola to its list of regulated pests.

Growers should be especially vigilant when moving boxwood into the US to ensure their product is free of the disease.

Nurseries enrolled in the Clean Plants program have access to a Boxwood Blight module to assist with minimizing the risk of moving this pest. Growers producing boxwood are encouraged to participate in this voluntary program.

Details of the module along with BMP’s are here .
