DESCRIPTION ECOLOGICAL THREAT
HABITAT IN THE UNITED STATES BACKGROUND BIOLOGY & SPREAD Scarification is necessary for the germination of lespedeza seeds. Mature seeds of this genus remain viable for up to twenty years; one study found a germination rate of 60% after cold storage for 55 years. Seedlings may represent only 1% of the seeds actually available in the soil. MANAGEMENT OPTIONS Since root reserves increase up to the flower
bud stage, all herbicide treatments should be completed in early to mid summer. The
addition of a non-ionic surfactant at a concentration of 0.5% improves
the effectiveness of foliar treatments. Triclopyr and clopyralid have
been shown to be effective in controlling Chinese lespedeza. A 2% solution
Triclopyr or 0.5% solution of clopyralid throughly mixed with water is effective
during the vegetative stage prior to branching or during flowering. Treatments
should cover the leaves and stems of plants to the point of runoff. These
herbicides are not labeled for use in wet areas or adjacent to streams. On
wet sites a 2% solution of glyphosate is effective from last June until seed
set.
