<div dir="ltr">For what it's worth, I have found that stiltgrass can still live underneath the Perilla. I pulled up a large patch of Perilla yesterday, and found a whole bunch of stiltgrass hiding underneath it. That particular bunch of stiltgrass until then had avoided my notice, weeding hands, and Rodeo-filled spray bottle. So this could be seen as a cooperative arrangement between the two, rather than a competitive one. Non-scientifically speaking, of course.<div><br></div><div>--Susan Gitlin</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Aug 31, 2020 at 12:04 PM <<a href="mailto:maipc-request@lists.maipc.org">maipc-request@lists.maipc.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Send MAIPC mailing list submissions to<br>

Subject: [MAIPC] Microstegium versus Perilla, August 30 2020<br>

Microstegium versus Perilla<br>
<br>
<br>
<br>
I came across a huge mono-culture of Japanese stiltgrass about 25% of an<br>
acre. In the middle of the patch was a monoculture patch of Beefsteak mint<br>
about 15 feet x 20 feet with almost no stiltgrass. There were two other<br>
beefsteak patches about 5 x 10 feet with no Microstegium. Is this just one<br>
non-native invasive outcompeting another one? Or is there another<br>
possibility that could be explored? For example, reintroduce Mentha arvenis.<br>
Any potential biocontrol?<br>
<br>

For whatever reason- Perrilla seems to outcompete JSG.<br>

I would dig up the roots first. Beef steak plant has a different root structure.?And it is poisonous to cattle, so no, I would not purposefully introduce it.. you never know who will misunderstand that recommendation. The landscape use of a site changes over time and ownership.?<br>
Stilt grass is not poisonous.?<br>
