[MAIPC] Microstegium versus Perilla, August 30 2020

[Melissa Bravo]

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. 
Stilt grass is not poisonous.

 We also noticed this in the field Marc.
For whatever reason- Perrilla seems to outcompete JSG.

Microstegium versus Perilla

 

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