Blackberry

Disclaimer

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

Non-chemical control

Physical removal

  • Physical removal by repeated slashing may limit the spread of Blackberries but it is not an effective method of control when used alone
  • Blackberry will regenerate from root suckers, and whole canes growing along the ground will often be missed by the slasher blades.

Cultivation

  • Competition from well managed pasture will help prevent the establishment and spread of Blackberries on grazing land.
  • Where machinery can be used, established Blackberry thickets can be dozed out and the area deep-cultivated to destroy the root system.
  • Repeated cultivation is necessary to destroy seedlings and regrowth before the area is sown to pasture or crop.
  • Seedlings and regrowth from root fragments can also be sprayed for one or two seasons after physical removal.

Burning

  • Large infestations of Blackberry can be removed by burning however, follow-up treatment of regrowth by herbicide, grazing or cultivation is essential.
  • Blackberry thickets pose a fire risk and care should be taken in burning blackberry near native or other valuable vegetation, fences and buildings.

Grazing

  • Goats readily eat Blackberries and are capable of destroying large infestations
  • Sheep are useful to some extent in the control of Blackberries because they eat seedlings and young tip growth.

Chemical control

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

Application method:

1. Foliar spray

  • Stage of growth - actively growing
  • Location - Pasture and non-cropping
  • Suggested herbicide - Roundup®Biactive™

2. Cut stump/ cut and paste

  • Stage of growth - actively growing
  • Location - Pasture and non-cropping
  • Suggested herbicide - Vigalant®
