Harvest weed seed control - narrow windrow burning locations
Aims

To understand how effective narrow windrow burning is capturing annual ryegrass seeds (comparison of between row and inter-row measurements), and to determine the reduction in ryegrass as a result of burning (comparison of burnt and unburnt sections of the row)

Key messages

Narrow windrow burning canola can be an effective tactic against ryegrass provided weed seeds can be captured and concentrated at swathing & harvest. Of the ryegrass seed captured between 93-99% was controlled by burning narrow windrow canola
