To help protect our environment:
Scrub, riparian and forest margins, shrublands, fernland, riverbeds, wetlands, sand dunes, roadsides, wasteland, pastures, orchards, plantations.
Seeds dispersed by birds, other animals, water and soil movement. Vegetative spread from rhizomes.
Displaces and smothers native vegetation. Reduces pasture production and capacity and injures stock. Can dominate forestry plantations, impeding access and reducing overall yield. Host for blackberry rust Phragmidium violaceum.
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.
