Boxwood Blight (PPFS-OR-W-20)

Boxwood blight is a disease of boxwood (Buxus spp.) that causes rapid defoliation and plant dieback. Plants are eventually weakened by repeated defoliation and dieback, and the resulting plant stress and consequent colonization by secondary invaders leads to plant death. This fungal disease is particularly devastating to American boxwood cultivars, which can defoliate within a week and die within one growing season.

Boxwood Blight (PPFS-OR-W-20) is available online.
