How to kill Paterson’s curse
For small patches or limited infestations, where labour is not a limiting factor, manual removal of the plant is a highly effective method of control. Vigilant II can also be used, applied to 50% of the leaves.
For large, well-established infestations it is advisable to use Stinger at a mix rate of 10 g/100 L of water with surfactant (an organic compound). Grazon Extra can also be used at rate of 2.5 mL/1 L of water with a foliar spray.
