Weeds : Tumblemustard (Jim Hill mustard) : Sisymbrium altissimum
(revision date: 6/9/2014)

Family: Brassicaceae (Cruciferae)
Cycle: Annual
Plant Type: Broadleaf

Biology
Tumblemustard grows 2-5 feet tall. Seedling plants are low-growing rosettes of deeply lobed leaves. Mature plants have stems that are simple below, and many-branched above, providing a bushy appearance. While lower leaves are coarse and divided into broad leaflets, upper leaves are finer with narrow segments. Flowers are small and pale yellow. Fruit are thin 2-valved capsules 2 to 4 inches long. Seeds are small, numerous, yellowish-brown, and oblong with a groove. The plant often breaks off at soil level when mature and spreads its seed while "tumbling" in the wind.
Habitat
A native of Europe, tumble mustard now thrives throughout North America on small grain fields, rangeland, waste areas, and roadsides.

Management Options

Non-Chemical Management
  • Cultivation (rototilling or hoeing) will effectively eliminate plants.
  • Hand-pull to eliminate weeds.
  • Careful digging is useful to manage weed populations. However, digging can carry undesirable weed seed to the surface and foster further germination.
Select non-chemical management options as your first choice!

Chemical Management

Not a problem in healthy established turf. Apply according to label directions. Glyphosate and glufosinate products should be applied as spot treatments only! NOTE: Some ingredients listed here are only available in combination. Read the label carefully on combination products to make sure the product is suitable for your specific situation.

Landscape areas
  • glyphosate
  • glufosinate
Turf areas
    Bare ground areas
    • glyphosate
    • products containing 2,4-D
