Capeweed

Disclaimer

The following page is a brief summary of information available on the DPIPWE website regarding Capeweed control. For more information view here

Non-chemical control

Physical removal

  • Pulling or grubbing can remove Capeweed where infestations are small.
  • Use a fork as Capeweed can be difficult to pull by hand. First loosen the soil around the plant then lift, taking care to remove as much of the root system as possible.
  • Chipping is generally unsuitable as regrowth from the portion of root left in the ground is likely.

Cultivation

  • Cultivation can be used to remove established infestations. Cultivate to expose the root systems with minimal breakage and leave the plants to dry out and die.
  • Cultivation can be combined with cropping or pasture establishment to control large and well established infestations.

Grazing

  • Grazing management should aim at maintaining a continuous and vigorous pasture.
  • Heavy grazing during late winter or early spring can control Capeweed.
  • Heavy grazing during late summer or early autumn has the opposite effect, as the bare patches of soil left behind are readily colonised by Capeweed seedlings.
  • Under-grazing can also favour Capeweed as pasture grasses and clover are grazed preferentially, leaving the Capeweed to mature and produce seed.

Chemical control

Herbicide control is only a short term solution; unless a vigorous sward is established to compete with the capeweed, the weed is likely to re-establish.

Use herbicides in accordance with label. Refer to APVMA permit PER13160 where herbicide is to be used in non-cropping and bushland areas
