Using barley cultivars for non-herbicide control of grass weeds locations
Aims

To compare the competitive ability of new and existing barley varieties in the presence and absence of weeds.

Key messages
  • ‘Compass type’ varieties with good early vigour, combined with a prostrate growth habit are the best competitors (Compass, Fathom, Scope CL, RGT Planet).
  • ‘Hindmarsh type’ and ‘Urambie type’ varieties with very slow early vigour are poor competitors (Hindmarsh, Spartacus CL, Urambie).
  • In the presence of grass weeds there was an average of 0.9t/ha yield loss across all barley varieties.
  • Three years of data has reinforced that certain varieties can be used as a non-herbicide option for grass weed control.
