Special disposal notes: Most or all of its spread is by tubers and runners/rhizomes, through dumping of greenwaste, as very little is likely spread by spores.
How to Control:
- Pull out, Leave on site to rot down. Dispose of tubers and runners at a refuse transfer station, burn or bury.
- Spray with 1g metsulfuron/10L water). Leave sprayed sites 3-4 months to allow herbicide to translocate to tubers before clearing or replanting.
Easy to kill. Runners and tubers resprout if not disposed of carefully.
Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
