To help protect our environment:
Wetlands, riparian margins, drains, damp ground, pasture, forest, coastal sandy habitats.
Seeds dispersed by birds, livestock and water. Vegetative spread from rhizomes, exacerbated by feral pigs. Human-mediated dispersal through soil movement, dumping of garden waste and deliberate plantings.
Forms dense patches, excluding other plants in wetlands, riparian margins and damp forest gullies. Displaces valuable pasture species and is toxic to livestock.
Follow up treated areas 3 times per year. Encourage natural regeneration of native plants or replant treated areas where possible after 2-3 treatments to establish dense ground cover and minimise reinvasion.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
