Tall, erect, evergreen, rhizomatous grasses <10m or more high. Stems smooth, hollow canes. Alternating leaves.
Roadsides, shelterbelts, settled areas. Tolerates wide range of conditions but not shade.
Some are clumping varieties, others have vigorous runners.
Vigorous & persistent. Spread rapidly, form dense stands excluding all other vegetation.
Digging trench around bamboo can contain spread.Control with weedmat ineffective. Don’t replant until 6 months after last herbicide application. Do not burn the stems as they may explode if heated.
1. Dig out & dispose.
2. Cut down close to ground; spray regrowth before it reaches 60cm (200ml Amitrole + 20ml penetrant/10L), continue respraying at under 60 cm until regrowth ceases (usually requires 4-6 treatments). Minimise Amitrole contact with soil & other vegetation as it is non-selective, residual, and corrosive.
3. Cut stray emergent shoots at ground level, inject 10ml undiluted Amitrole into each stem.
4. Amongst desirable plants spray (300ml haloxyfop + 100ml crop oil/ 10L).
5. Apply hexazinone 10cm into soil by injection 30cm apart or in trenches cut on uphill side of infestation & at 1m spacings inside infestation (no application on downhill edge). Use with extreme caution, hexazinone is residual in soil. Will leach, use during dry periods &/or dig trench around treated area to minimise adverse effect to surrounding area.
Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.
