WOOLLYLEAF BURSAGE BIOLOGY AND CONTROL

---

Summary.
Woollyleaf bursage, [Ambrosia grayi (A. Nels.) Shinners], also known as bur ragweed, is a perennial noxious weed native to Kansas. It is a member of the Composite family and was referred to previously as Franceria tomentosa in the false ragweed family. Taxonomists were not able to distinguish between Ambrosia grayi and
Franceria tomentosa and thus the accepted current Latin name is Ambrosia grayi. Woollyleaf bursage infests
more than 80,000 acres in Kansas, primarily in the western half of the state. It is adapted to low areas where water runoff collects in cultivated fields or in noncropland areas. The collection of water and the deep perennial root system, which can reach a depth of 15 feet, allow woollyleaf bursage to survive extended periods of drought or harsh weather. These circumstances make it very difficult to control. The development of irrigation may be extending the areas of adaptation beyond the immediate ponding areas, raising concerns that woollyleaf bursage acreage is expanding.
