[MAIPC] FW: [INVASIVES] Reminder

[Marc Imlay]

So could we gather seed of the native Virginia Wild Rye,  Elymus virginicus, in the park and plant them in the mono-cultures of Japanese Stilgrass?

Let's all look for leaf blight on Japanese Stiltgrass this Summer. Question? The three locations where I found leaf blight on Japanese Stiltgrass in the 200 acre Ruth Swann Park in Charles County MD in the past few years, including one significant size patch, all had the native Virginia Rye nearby. What native plants could be a source of Bipolaris?

Japanese stiltgrass


The annual grass Japanese stiltgrass (Microstegium vimineum) can be highly invasive, especially on disturbed sites, and it is currently widely distributed in the eastern U.S.  In Oak Ridge National Environmental Research Park, Tennessee, Japanese stiltgrass was ranked the most aggressively invasive nonnative species, based on distribution, abundance, relative difficulty of control, and ability to exclude native plant species (Fryer 2011).  Two species of Bipolaris have been described as cause of leaf spots and necrosis of Japanese stiltgrass in the Eastern U.S.; some evidence is that disease may be suppressing local populations.  Host range of these species has not been fully tested, although limited symptom development was reported on a few important grass (grain) species in artificial tests (Kleczewski et al. 2012).  Research is on-going about this pathogen(s), its host, and the potential for use in biological control of Japanese stiltgrass. If you see leaf blight on Japanese stiltgrass during the growing season please contact work group member William L. Bruckart, III.
