I
was at the Blue Mill Cafe on 9th Street the other day and I saw a
Photinea hedge in the parking lot. I suspect it belonged to the
business next door, however I saw some problems that I see all over
Modesto.
The foliage was silvered mottled. It looks like spider mite damage
but not quite. With spider damage as bad as this, is you see a lot of
very fine webbing surrounding the foliage and branching. Not typical
spider webbing that is intended to catch other insects but webbing that
surround the foliage and branch like cotton candy on a stick.
Here you see the silvering with small black specks on the leaf that scrape off. It is caused by Lace Bug.
From Minn. Extension service
By looking at Photinea, Indian Hawthorn and related members of the
rose family it is obvious that they can survive substantial damage.
Chemical control needs to be started in late spring or early summer and
we recommend Orthene. You can get some control using Pyrethryns or
synthetic pyrethryn like cyflutheryn. In some cases insecticidal soap
can help
