Erect, spiny annual herb < 1 m tall. Leaves are white and hairy on underside. Flowers are inconspicuous and are borne December – April. Fruits/burs have hooked spines.
To help protect our environment:
Maize crops, poultry farms, moist and disturbed soils.
Seeds dispersed by attachment to animal pelts, gravity and water. Human-mediated dispersal through attachment to clothing, contamination of maize and livestock.
Burs contaminate and reduce value of sheep wool. Spines prevent stock from grazing and can damage feet or hinder movement. Weedy in summer crops, potentially reducing crop yield. Can displace desirable pasture species.
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.
