Boxwood blight causes rapid defoliation and plant dieback of boxwood (Buxus spp.) and other susceptible hosts within the boxwood family (e.g., Pachysandra and Sarcococa spp.). Infected plants are eventually weakened, and the resulting plant stress and consequent colonization by secondary invaders often results in plant death. This fungal disease is particularly devastating to American boxwood cultivars, which can defoliate within a week; weakened plants can die within one growing season.A newly updated publication, Boxwood
Blight, includes large color images to aid in diagnosis. Symptoms, cause, disease development, and management strategies are discussed in the text. The management portion has been divided into two sections to address specific recommendations applicable to the following production systems:
• Nurseries & Retail Centers (commercial)
• Landscapes (commercial and residential)
