Shothole is a common bacterial disease on Otto
Luyken, Zabal and Schip laurel plants. The diseases name is
descriptive of the symptoms: it looks like someone shot the shrub
with a shotgun! Wet leaves seem to make the disease worse, so make
sure not to water your plants from overhead. If your shrubs are very
close together or near a wall that prevents leaf drying, prune them
to enhance air flow.
The fungicide Mancozeb or products
containing fixed copper are effective against shothole if you choose
to spray a pesticide.
Mancozeb is almost impossible to find
at garden centers but is available here at
Cooper Seeds
in Lawrenceville.
Make sure to read the
label and follow the directions completely.
