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

[Jessica Walker]

I would think that removing epicormic sprouts would actually increase entry potential through the creation of fresh wounds which would attract elm bark beetles. However, if the removal is done during winter when the beetles are less active, that may be a different case.

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.

Russell

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.
