General Best Management Practices:

Contact your local weed control agency for site specific BMP's

• Control is difficult because of the extensive root system.
• Long term Management should be implemented due to the plants aggressive nature and inconsistent response to control.
• Rapid response and early control in the May/ June is critical to prevent seed production which occurs approximately 30 days after yellow green bracts form.
• Spot Spray small patches and monitor for new infestations.
• Cultivation is not recommended because root fragments can spread the infestation.

Prevention (Prev) is always the best method! Monitor your land and destroy single plants before seed production to avoid costly expense.

Mechanical (Mech) and physical control methods include hand pulling, digging, cutting, mowing and tilling.

Cultural (Cult) control methods include biological control agents, livestock grazing, and revegetation practices.

Chemical (Chem) control methods include the use of selective site-specific herbicides. Always read and follow the label!
