Harvest weed seed capture locations
Aims

To see if harvest weed seed practices could be adopted to reduce annual ryegrass (ARG) weed seed populations to address herbicide resistance issues in high yielding, high rainfall zone (HRZ) areas of the southern region.

Key messages
  • Timeliness of harvest is critical to try and maximise the number of annual ryegrass (ARG) weed seeds captured (prior to the onset of seed shedding).
  • Harvest height will aid in the capture of increased numbers of ryegrass.
  • The amount of ARG captured will depend on conditions prior to harvest and the level of lodging that occurs prior to harvest.
  • When weed levels get too high, several years of alternative crop sequences may be required to get numbers down to an acceptable level.
