[MAIPC] FW: Ailanthus control

[Muth, Norris (MUTH)]

I can’t speak to Ailanthus wilt in Maryland, but in Pennsylvania applications it does a nice job decimating treated stands, but it has very slow (to non-existent) spread from the treated stands. The up-side to that is that you can carefully plan which stands you are ready to take out. The down side of course is that it requires hitting many stands independently.

Great article, I would say the figure($3,500) used to describe how much it can cost to treat and acre of Ailanthus is very extreme.  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.

Thanks,

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.  Aaron may be on forest fire duty out west right now somay not be imediately available.

Marc

I've met you on a few MNPS walks, but you probably wouldn't remember me.



Do you know whether the verticillium wilt fungus described in

http://www.tandfonline.com/doi/abs/10.1080/09583157.2015.1023258?journalCode=cbst20 is having much effect in Maryland yet?

Thanks,

Chris Spaur
