How to kill manuka
For control of manuka apply Grazon Extra at a rate of 500 mL/100 L of water and add Pulse Penetrant at 200 mL/100 L of spray. Thoroughly wet foliage, stems and soil around the base of the plants.
Where slashing has resulted in regrowth, allow at least one year’s regrowth or until regrowth has reached 1 m tall before treatment.
