To help protect our environment:
Grassland, pasture, riverbeds, roadsides, wastelands, plantations.
Seeds dispersed by attachment to wool, fur and clothing.
Burs get tangled in and contaminate sheep wool.
Maintaining good pasture cover can prevent establishment or suppress an infestation. Prevent overgrazing especially in summer. Other herbicides are available for selective use in pasture.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
