<div class="userStyles" style=" font-family: Arial; font-size: 12pt; color: #000000;">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.

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Arial",sans-serif">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.<o:p></o:p></span></p>
