Stock generally avoid grazing the species, but will browse it in the absence of alternative feed resulting in the tainting of meat or milk from those animals.

Herbicides must be applied at the appropriate rate as specified on the label and all safety precautions followed. If chemical control is necessary near drainage lines or streams, use extreme caution as the effects on aquatic life can be devastating even in minute amounts. Always seek expert advice.
