Dogwood trouble?

13 years ago

Hello: We planted a young native dogwood a year or two back (variety Appalachian Spring), which is about 6-7 feet high. The base of the trunk has a lot of loose, flaking bark, and our tree person (MD-certified arborist) said this is from borers. He said that removing the loose bark and spraying with Diazinon or Dursban (?) would work, but I also know that these are not available to homeowners anymore. But I've also heard that this may not be borers, so here are photos showing what's going on. Thoughts? Thank you!

Actually, spraying with a contact pesticide like Diazinon or Dursban (even if you could get them) won't help with borers at all.

You'll need to let us see some close-up shots of the problem.

rhizo is right....topical sprays will not get to the borers, You may be dealing with a stem canker instead....a close up photo would really help
