Preemergence and Postemergence Control of Japanese Stiltgrass

Indiana university, (Japanese stiltgrass frequently invades forest
understories, particularly where there are light gaps or litter disturbance.
It is also very common in floodplain areas, along streams, and other areas
of overland water flow.
It produces prolific seeds and can reproduce in as
low as 5% sunlight.)

Pa Dept Conservation and resources, nice page. (Native to Asia, this
successful invasive has colonized most of the eastern United States, as far
west as Texas. )
-
Japanese stiltgrass displaces native plants and threatens bird and
wildlife populations that depend on native vegetation as
part of a supporting ecosystem. Using a pro-active approach to quality
vegetation management can reclaim native species
and help restore habitats. (BASF)
My Original data:
New to this region around 2002, Everywhere the government
projects seed the highways, parks and greeways... now has the prolific spreading
plant. It has taken over most of the wooded areas. Greenway flood
plains are quite beautiful in the deep woods. It looks like a green carpet all
through the thicket.
Woody stems, puts out root shoots every few inches. In the fall, it has
a pink-purple flower about 3 mm shaped like a
camelia.
Flower is only one per stem... last leaf cluster. I'll get picture this Fall.

Upper Neuse River Gereenway,June 22, 2015
6:45 AM and 76º is a nice ride, but lighting is not
ideal due to low sun angle
Wind noise from sound ports diminshes as I slow down
after crossing US Highway one overpass. The weed does make for a very
attractive flood plain and woods. Of course it's not the only weeds.
