Managing clethodim resistant ryegrass without oaten hay locations
Aims

To conduct a multi-year trial to determine the effects of crop sequence and low, medium and high intensity management strategies to reduce clethodim-resistant ryegrass

Key messages
  • The decline in ryegrass has been greater after field peas.
  • The high intensity herbicide strategy was the most effective option in both rotations.
