Buxus blight is a disease of boxwood (box) hedging plants. It causes dieback and browning off of leaves and shoots.
Buxus blight (box blight) is a disease caused by the fungus Cylindrocladium buxicola. It has become common in the UK, Europe and in New Zealand.
Buxus blight causes dieback and browning off of leaves of boxwood, which drop off. Stems become bare and sometimes with dark streaks.
To help identify the disease, place a few leaves in a plastic bag with a moist tissue for a few days. If white spores form, it is box blight. Spore masses of volutella (a similar dieback disease of box) will look pink.
