Control method
Foliar Spray
Herbicide is diluted with water at a specific rate, and sprayed over the foliage to point of runoff.
Most suited to shrubs, grasses and dense vines less than six metres tall.
Manual and Mechanical Removal
Manual control uses hands or hand tools to control weeds.
This can be an effective control as it can minimize soil disturbance and can instantly remove the entire weed.
Mechanical control suits larger infestations, using power tools and machinery to reduce the bulk of the problem.
Mechanical control can include slashing, mowing, dozing, harvesting, and felling.
Herbicide warning
Before using any herbicide always read the label carefully and ensure that the chemical is registered for use on the target weed. All herbicides must be applied strictly in accordance with the directions on the label.
