[MAIPC] Japanese Stilt grass

[jmaher55 at verizon.net]

Deer do not eat grass except for cereals. However, if they eat it and cannot digest it, it will clog up their digestive tract and they will starve. Same with cattle.

 

In Virginia, it is illegal to feed deer during deer season state-wide. In those counties near CWD, it is illegal year round. 

 

Do not know about Maryland laws.

My understanding is that deer don't eat grass. They are browsers, not grazers. So I don't think this could work. What is definite is that the deer help to spread stiltgrass and wavyleaf.

Has anyone tried to spray stilt grass with an “attractant” that may induce deer browsing?  I’m not sure what deer like in the sense of taste but a spray of “sugar” may get them to at least browse the plant which from my observations they appear to shy away from? Just a thought.

Today at Ruth B. Swann Park in Charles County Maryland, I came across about a quarter acre that had only dead stilt grass from last year. The dead stilt grass was very thick but there was no live stilt grass or any other green vegetation including beefsteak plant, Perilla frutescens.  There was a lot of Perilla about 300 feet away.

If it kills the seedbank and you remove Perilla, the stilt grass would not come up at that location the next year (unless it came in from elsewhere).

I don't know.  I'm trying to think how to figure that out.

 

 I think if I look for the first spring/early summer growth of both plants, there would be the clue.  Is that right?

 

Killing the seedbank would mean perilla comes up mostly alone except for stiltgrass seed that blows in late the prior year.So maybe that would be a smaller "crop". So the result is the stiltgrass that year is sparse.  

 

One thing is perilla is usually still carrying and presumably dropping seed well after the stiltgrass seems finished.

 

I will watch patches of perilla on TRI this spring/summer.

Does the Perilla kill the seed bank or just the emerging stiltgrass? Marc

>From observation in woodlands environments at Theodore Roosevelt Island and in Donaldson Run Park it appears that Perilla may have a toxic effect on Japanese Stiltgrass which will not grow under the Perilla plants or is very sparse.  Also on a larger scale at Gambrill State Park in Maryland this was obnserved last summer.
