Harvest weed seed control – narrow windrow burning paddock case studies locations
Aims

To assess the effectiveness of narrow windrow burning practices in the Mid North as a late weed seed control tactic against ryegrass in canola and wheat.

Key messages
  • Narrow windrow burning can be an effective tactic against ryegrass provided:
    • 1) weed seeds are captured and concentrated at swathing & harvest
    • 2) the burn heat and duration are enough to kill weed seeds.
  • Annual ryegrass control in canola was more variable than last season with 37-86% control of the seed captured and concentration in the windrow. Higher control (86-93%) was achieved for wheat residues concentrated into narrow windrows.
