Roots: Fibrous initially, becoming dense, extensive and crown-like with age. Will set root from stem fragments when in contact with the soil.

Dispersal: Seed is spread by wind, water, animals, humans, contaminated soil (earthmoving equipment, car tyres etc) and garden refuse dumping. (particularly Ipomoea indica).

General Biosecurity Duty

All plants are regulated with a general biosecurity duty to prevent, eliminate or minimise any biosecurity risk they may pose. Any person who deals with any plant, who knows (or ought to know) of any biosecurity risk, has a duty to ensure the risk is prevented, eliminated or minimised, so far as is reasonably practicable.

Control

Cut vines close to the ground and dig out as much of the root system as possible. The remaining vines in trees can either be removed or left on the tree to rot. Do not yank stems running along the ground as rooted fragments will snap off and grow again.
