Brome grass management. Part I: selecting the right rotation and herbicide locations
Aims

To investigate selection of the right rotation and herbicide strategy for brome grass management.

Key messages
  • The ecology of brome grass has changed, making it more problematic to control in crops. Higher levels of seed dormancy are allowing brome to escape pre-sowing control tactics, resulting in greater in-crop emergence.
  • Increased seed dormancy associated with a requirement for cold or chilling. Under field conditions this increased chilling requirement would not be met until late Autumn or early Winter.
  • Knockdown herbicides are less effective in the management of highly dormant populations of brome. Therefore, brome grass management has become heavily reliant on Group A and B herbicides, especially the Clearfield(TM) technology, which is expected to increase the risk of herbicide resistance development.
  • High levels of seedbank persistence from one year to the next (approximately 25%) means multiyear control of brome grass is required to exhaust seedbanks to manageable levels. Plan a three-year rotation.
