A three year strategy to manage clethodim resistant ryegrass without oaten hay locations
Aims

To report on a three year strategy to manage clethodim resistant ryegrass without oaten hay.

Key messages
  • Effective management of clethodim-resistant ryegrass can be achieved by using combinations of control tactics, effective herbicide strategies, and more competitive crops.
  • Oaten hay remains one of the most effective phases for ryegrass management but effective control of ryegrass regrowth and seed set are of critical importance.
