Presented by Dr. Tom Hsiang University of Guelph, Ontario, Canada
Volutella blight is commonly found on boxwood plants worldwide. Although some consider it mainly a saprophyte surviving on dead tissues, it is capable of initiating disease on live wounded tissues. Here we present some background on the disease, some basic biology on how it causes infections, and end with its disease cycle and recommendations for management in nurseries.
