|Biology /notes on reproductive |
|Copious seed production, regrowth after mowing, glandular
trichomes on seeds, possibly containing allelochemicals.
|Control methods||Early detection and control is essential to minimise economic
impacts. Herbicides known to be efficacious include Brush-off®,
Access 240® and Climax®. Biocontrol research is under
development; mechanical control is usually ineffective.
|Practicality and ease of control||Timing of herbicide application and follow-up is important for
