[MAIPC] FW: Ailanthus control

[John Ambler]

A big patch dominated by ailanthus trees was killed about two years ago by
others.  Seeing what is regrowing there now reminds me that it is important
to consider what invasives will move in after a forest patch solid with
ailanthus is removed.

Slow killing of ailanthus with the wilt fungus may allow time to address
control of other invasives where the ailanthus is.  Or initially just
killing ailanthus female trees as a start of control may be wise.

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.

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
