Hi Betsy.
Let's all look for leaf blight on Japanese Stiltgrass next Summer. Let's
request funding for research on safe and effective biological controls
including research in China to verify the scientific reports that 3 Asiatic
species of rust are pathogens only on the genus Microstegium. How can you
folks request this funding? Would Towson University be interested? What
about both the state and Federal legislatures? The three species of rust
were Puccinia benguetensis, P. polliniae-imberbis, and P. polliniicola (in
one of 2 references). Invasive Plants of Asian Origin Established in the US
and Their Natural Enemies, Vol. 1,

Marc this has become the new garlic mustard substitution for out of
control invasives in the Patapsco Valley.
What do u suggest to get rid of it without chemical application?
Happy holidays!

awesome Patapsco River Valley!
Actions speak louder than words! Make a positive difference every day!

Biological control updates with references, research contacts, and
resources for 18 Mid-Atlantic non-native terrestrial and aquatic invasive
species are available in this MAIPC Biocontrol Work Group document on our
MAIPC web site.

At a workshop it was estimated that for ~30 percent of the invasive plant
species there is an effective, host specific, biological control if we do
the research that will make host specific biological controls available. One
example is Japanese Stiltgrass. The update covers curent work on biologial
controls. New work could include work in China on the 3 Asiatic species of
rust that current literature indicates are pathogens only on the genus
Microstegium,

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.
