Windrow burning observations and thoughts (Planned Future Trial) locations
Aims

During 2013 harvest Mr Roger Bolte of Wyalong established windrows in paddocks in an attempt to help manage herbicide resistant ryegrass populations.

Key messages

To effectively establish windrows requires forward planning and potentially slows harvest tand increases harvest costs. Burn as early as conditions allow. Make it a priority job. Small rainfall events may germinate weeds in burnt areas that require attention before the whole paddock area.

Acknowledgments

CWFS would like to acknowledge Roger Botle's support of this trial.His commitment and effort in leaving a nil treatment plot in his paddock during harvest and esrablishment o fwindrows to manage weed seed numbers is a major contribution to research and development within the locl gains industry and CWFS.

Other trial notes

At harvest, there was a rye grass population averaging 6.4 plants per square metre ranging from 0-27 plants/square metre that had surivived all the attempts to kill in the previos crop. If harvested the paddock traditionally, for every 1 metre the header travelled it would have spread on average 8202 of herbicide resistant rye grass (100% germination) with a range of 4106 to 13501 seeds back over the paddock. This seeding rate resulted i
