<p class="MsoNormal">I noticed at the low rate I was applying clethodim, it wasn't killing Dicantheliums, but was impacting Leersia virginica. We are all growing very concerned Microstegium's success at dramatically increasing populations annually despite time
consuming control efforts each year. At this point it is colonizing rare habitats that we thought we could keep it out of if we managed it every year, such as our Magnolia bogs.<br>
<br>
I personally have all but abandoned trial attempts to manage Oplismenus undulatifolius with grass specific or pre-emergent herbicides. Although both work very well at killing or preventing first year plants, the second year Oplismenus plants are harder to manage.<o:p></o:p></p>

We use the selective grass herbicide quizalofop-P (e.g. “Assure II”) at its lowest labeled rate, and find that stiltgrass is controlled while other grasses such as Leersia virginica, Muhlenbergia scherberi, and Brachyelytrum erectum are not affected, nor any
dicots or non-grass monocots.<br>

Be well.<br>
