I’ve been in vegetation management for 22 years and in most bid situations, I would doubt you would spend more than $500/acre for chemical treatment of Ailanthus even in the most dense stands. This time of year is prime time to incorporate hack n squirt methods with a 50/50 solution of your favorite glyphosate brand. Large trees can be treated in this method and the smaller trees can be basal(Pathfinder II RTU) treated with high success rates due to the fact that herbicide is being taken down into the roots this time of year. Don’t try these same methods in the spring or early summer and expect to control the root systems of Ailanthus. Don’t get me wrong I am excited about the potential that the Verticillium Wilt could bring. Ailanthus is public enemy number one when it comes to invasives in my book. Any help biologically would be great especially on this species. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Thanks, <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Berlin Sans FB";color:#1F497D'>Todd Hagenbuch<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Berlin Sans FB";color:#1F497D'>Vegetation Management Specialist<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Berlin Sans FB";color:#1F497D'>Arborchem Products <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Berlin Sans FB";color:#1F497D'>133 Portsmouth Circle<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Berlin Sans FB";color:#1F497D'>Glen Mills, PA 19342<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Berlin Sans FB";color:#1F497D'>570-401-7098<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Berlin Sans FB";color:#1F497D'><a href="mailto:thagenbuch@arborchem.com">thagenbuch@arborchem.com</a><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Berlin Sans FB";color:#1F497D'><a href="http://www.arborchem.com/">www.arborchem.com</a><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma",sans-serif'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma",sans-serif'> MAIPC [<a href="mailto:maipc-bounces@lists.maipc.org">mailto:maipc-bounces@lists.maipc.org</a>] <b>On Behalf Of </b>Earl "Bud" Reaves Jr.<br><b>Sent:</b> Friday, September 02, 2016 8:27 AM<br><b>To:</b> Marc Imlay<br><b>Cc:</b> <a href="mailto:misraspaurs@gmail.com">misraspaurs@gmail.com</a>; MA-IPC MA-IPC<br><b>Subject:</b> Re: [MAIPC] FW: Ailanthus control<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal><span style='font-family:"Comic Sans MS"'>Marc\Chris et al, The latest info I believe is in the August Invader of the Month see link below.Aaron Cook, the author, may have the most recent but i don't suppose anything has changed in the last month.
