Could Japanese chaff flower have agricultural impact? A recent field day at Southern Illinois University's Belleville Research Station taught growers how to recognize the plant if they see it in their fields. See the information below with a link to the full article from Illinois Farmer Today.
"Achyranthes japonica, or Japanese chaff flower, is a relatively
new invasive species that is plaguing the Ohio River Valley. This
species is a relative to some prominent agriculture weeds and grows in
both forested areas and along agriculture field
margins. Thus, all land owners/managers should be aware of this rapidly
spreading species and know how to identify and control it. Southern
Illinois University, the only university conducting research on this
species in the U.S., did this at their annual Belleville
Research Field Day in July. Over 150 people attended the field day
where they learned, in part, about Japanese chaff flower and its threat
to their properties. Some of the threats posed by this species is that
it has continual germination throughout the growing
season, it is a perennial species, and it can spread rapidly by a
variety of vectors. Also, Japanese chaff flower has about a 97 percent
germination rate; whereas other weed species in the family have about a
14 percent germination rate. With help from field
days like this, information about Japanese chaff flower, and other
invasive species, reaches the public in a positive way. Please do not
hesitate to report any sightings of Japanese chaff flower. " --Lauren Schwartz
