Expert Response
Thank you for your question, but before I give
diagnosis and possible solutions are the infections
similar to these photos as you did not provide any.
Thank you.
They are similar to the second photo, with the "fuzz" on the branches, not the leaves.
Thanks,
Mike
Yes this appears to be Magnolia Scale which is
quite common this year. The links that I have listed
below will go into characteristics of the insect
causing the scale and treatment suggestions. As the
articles point out timing of treatments critical as to
when applications are done. This time of year
applications of a listed insecticide is the best
treatment with a follow up next March with a
horticultural oil spray. When using any treatments
READ and FOLLOW the label directions of the
product you use.
I have also listed your County OSUExtension
Service as you may wish to contact them for advice
also.
