Boxwood Blight Insight Group (BBIG): Sanitation and Nursery Practices

By Dr. Fulya Baysal-Gurel • May 30, 2024

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
