Bracken fern (Pteridium aquilinum) is one of the most aggressive and persistent weeds found in pastures, croplands, and disturbed areas. Its rapid spread is fueled by strong underground rhizomes, which allow it to regenerate even after cutting or burning. Because of this, traditional or contact herbicides often fail to provide lasting control.
Why Bracken Fern Is Hard to Control
Bracken fern’s extensive rhizome network enables it to store nutrients and regrow quickly after surface treatments. Even when the fronds are destroyed, the plant can re-emerge from the underground stems, making it a long-term challenge for farmers and land managers.
Effective Herbicide Solutions
Glyphosate-based herbicides, such as Roundup Turbo or Touchdown Forte, have proven to be effective against bracken fern when applied correctly. These systemic herbicides penetrate the fronds and move down to the rhizomes, helping eliminate the entire plant rather than just the visible parts.
Recommended Control Practices
-
Timing: Apply glyphosate when the fern is actively growing and has fully expanded fronds for maximum herbicide absorption.
-
Follow-Up Sprays: Conduct follow-up applications to target any regrowth from surviving rhizomes and ensure complete eradication.
-
Avoid Spray Drift: Take great care to prevent herbicide drift onto desirable crops or green plant parts, as glyphosate is non-selective and can damage nearby vegetation.
Sustainable Weed Management
Incorporating integrated weed management (IWM) practices, such as improving pasture cover, maintaining proper soil health, and monitoring regrowth, can help reduce bracken fern reinfestation over time.
Bottom Line:
Bracken fern control requires persistence and the right approach. By using systemic herbicides like glyphosate and following up with proper management practices, you can achieve long-term control of this aggressive weed and restore productivity to your land.
