<p class="MsoNormal">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.<o:p></o:p></p>

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.

<p class="MsoNormal">I don't know. I'm trying to think how to figure that out.<o:p></o:p></p>

<div>
<p class="MsoNormal"> I think if I look for the first spring/early summer growth of both plants, there would be the clue. Is that right?<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">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. <o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">One thing is perilla is usually still carrying and presumably dropping seed well after the stiltgrass seems finished.<o:p></o:p></p>
