Biology & Management of Volutella Blight caused by Pseudonectria buxi
Dr. Thomas Hsiang • August 17, 2022
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.

It is neither economically sustainable nor environmentally acceptable to make multiple fungicide applications to protect boxwood, a key nursery crop and iconic landscape plant, from boxwood blight.
This educational session aims to equip nursery producers, gardeners, and plant health professionals with vital knowledge and strategies to combat the pervasive threat of Calonectria pseudonaviculata, the fungus responsible for the devastating boxwood blight. Boxwood blight, a serious concern for the horticulture industry, jeopardizes the health and viability of boxwood plants, significantly impacting the ornamental plant market. Addressing this issue, the webinar will delve into the critical control points in nursery production, emphasizing effective sanitation practices to prevent and manage the spread of this disease. Attendees of the webinar can expect to gain: An understanding of the lifecycle and spread of Calonectria pseudonaviculata. Insight into the latest research and developments in boxwood blight control. Practical guidance on implementing effective sanitation and preventive measures in nursery production. Strategies for identifying critical control points to mitigate the risk of boxwood blight in their operations. This webinar is essential for anyone involved in the cultivation, care, or management of boxwood
