Most suited to shrubs, grasses and dense vines less than six metres tall.
Cut Stump
Involves lopping the weed close to the ground and then spraying the stump immediately (within 15 seconds) with herbicide to ensure absorption.
Basal Bark Spraying
Involves mixing a suitable herbicide in diesel and spraying the full circumference of the plant’s trunk or stem, completely wetting 30 to 45 centimetres from the ground level up the stem.
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.
