Combating ARGT through the use of safeguard ryegrass locations
Aims

To determine if the livestock carrying capacity of pastures in the Eastern Wheatbelt of Western Australia, including those on mildly saline soil, can be increased by replacing native ryegrass with the Safeguard variety of ryegrass.

Key messages
  • In 2004 there were no measurable differences in dry matter production between Safeguard ryegrass and Itialian/Wimmera ryegrass.
  • The sheep grazing assessment between Safeguard and Wimmera/Italian ryegrass we inconclusive.
  • The large differences in nematode galls between Safeguard and the Wimmera areas at the Driscoll site indicates that Safeguard successfully inhibited nematode gall formation.
