Silver grass is an annual grass occurring in cropping and grazing regions across Australia. There are several species, the most common being Vulpia bromoides and V. myuros. These species commonly occur together.

Silver grass is a slender annual grass with fine (0.5 to 3.0 mm wide) hairless leaves. It has a membranous ligule, no auricles and slender hairless stems. The seed-head is a narrow, one-sided panicle containing numerous seeds that have a straight terminal awn up to 14 mm long.

Factors that make Silver grass a major weed:

  • Competes with sown crops and pastures
  • Residues can reduce crop establishment and growth
  • An alternate host for cereal diseases
  • An undesirable component in pastures
  • Causes animal health problems

Further detail about this weed including integrated weed management tactics that could be considered when developing a management plan can be found in the section on problem weeds in the Integrated Weed Management Manual.
