Windrow burning can be an effective tactic in an integrated weed management strategy

What is the problem?

Windrow burning is one of several harvest weed seed control strategies that have been developed and evaluated in Australia to address the widespread evolution of multiple herbicide resistance in annual weeds.

What did the research involve?

Field and greenhouse studies were conducted to evaluate the effects of burning standing stubble and narrow windows on the survival of Italian ryegrass seed on the soil surface and to determine the amount of crop residue remaining after both practices.

What were the key findings?

Italian ryegrass emergence was 63, 48, and 1% for the unburned check, burned standing stubble and burned windrow treatments, respectively. Crop-residue dry weights were 9.94, 5.69, and 5.79 Mg ha−1 for these same treatments.

Final Comment

Windrow burning can be an effective tactic in an integrated weed management strategy for Italian ryegrass control in the Palouse region of eastern Washington and northern Idaho.
