Recommended approaches

1. Cut and stump paint (1g metsulfuron + 100 ml glyphosate + 10 ml penetrant/1L). Mulch.
2. Weed wipe (1g metsulfuron + 150 ml glyphosate + 10 ml penetrant /L water).
3. Slash tops, mulch. Dig out tubers, soak in herbicide or deep bury.
4. Spray (3g metsulfuron + 150 ml glyphosate + 10 ml penetrant /10 L water).

Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
