Roots:
Fibrous roots and lateral rhizomes

Habitat:
Pioneer species adapted to wide range of soils and climates

Reproduction:
By seed and vegetatively from roots

Management

Cultural/Preventative:

• Remove plant seeds from personal gear, clothing, equipment, machinery, vehicles, and animals before leaving an infested area
• Minimize soil disturbances and re-vegetate disturbed areas promptly
• Maintain healthy native plant communities
• Cultivate land
• Identify and monitor areas where invasions of sulphur cinquefoil is likely

Biological:

• No biocontrols are currently available, preliminary screening work is being conducted

Mechanical

• Small infestations can be hand-pulled; larger infestation can be cut to decrease seed production
• Multiple treatments will be required to exhaust plant's resources
• Monitor treatment success continuously over successive years

Chemical:

• Picloram, clopyralid, 2,4-D, and glyphosate all work effectively to control this plant
• Monitor treatment success
