Volutella Blight of Boxwood
Volutella blight (also called Pseudonectria canker) is the most common disease of boxwood in Kentucky landscapes and nurseries. This disease is caused by an opportunistic fungal pathogen that attacks leaves and stems of damaged or stressed plants.
A new Plant Pathology Extension fact sheet provides photos, along with descriptive text, to aid in diagnosing Volutella blight and differentiating it from other boxwood problems. In addition, disease development and management options are discussed.
Volutella Blight of Boxwood (PPFS-OR-W-26) is available online.
