Erect, perennial, densely tufted grass < 1 m tall. Rhizomes are creeping. Leaves are grey/green, tightly rolled and appear cylindrical. Flowerheads are borne in November – March.
To help protect our environment, from 1 September 2021, you:
Seeds dispersed by wind. Vegetative spread from rhizomes and rhizome fragments, dispersed by water. Human-mediated dispersal through deliberate plantings to stabilise dunes.
Forms extensive cover in sand dune habitats, substantially changing dune morphology. Rapidly accumulates sand, burying and displacing native dune species. Reduces shore bird nesting habitat.
Use haloxyfop where pingao or sedges present (NB haloxyfop will kill spinifex, stunt pingao). Follow up required annually until eradicated. Begin control at windward end of infestation, or where native veg is best represented. To prevent rhizome movement, control at eroding sites & prevent physical damage of marram at other sites. Spray after rain if possible to minimise salt contamination of herbicide, esp when using glyphosate.
CAUTION: When using any herbicide or pesticide please read the label thoroughly to ensure that all instructions and safety requirements are followed.
