[CANUFNET] [External email] Question to mailing list members

[Russell Eirich]

Epicormic growth probably means there is some factor causing decline in the overall tree health.  This would then correspond to a possible increased beetle predation with vector transmission of DED.

Just a thought - But I don’t have documented proof either.

Subject: [External email] [CANUFNET] Question to mailing list members

Here is a question that I would like to have posted to the subscribers:

Has anyone heard of the need to remove watersprouts from American Elm trunks because they could be a source of entry for the elm bark beetle?  We have been alerted to this by a university researcher who claims that leaving this growth on elms can leave them vulnerable to Dutch Elm disease. I have never heard of this and want to know if anyone has information to support it.
