Pests in Gardens and Landscapes
Pseudonectria canker—Pseudonectria rousseliana (conidial
state Volutella buxi)
Pseudonectria canker causes branches to die back and leaves to become tan in color. Leaves turn upward.
Small fungus fruiting bodies may appear on the lower surface of affected leaves and branches.
Provide plants with proper cultural care to keep them vigorous
and to limit these diseases. Prune out dead leaves and dead
and dying branches when they are first observed. Spraying
in the spring with fungicides
such as Bordeaux and
fixed copper may help control
the spread of the disease.
