To help protect our environment:
Open and disturbed areas, forest and riparian margins, forest gaps, roadsides, pastures.
Seeds dispersed by water and birds. Vegetative spread from roots.
Suppresses juvenile tree growth. Likely to outcompete and smother native plants in open, disturbed habitats. Barbs may injure children and pets.
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.
