Weeds: out with the harvest
GroundCover™ Issue: 19
Researchers looking at low-cost options for weed management have succeeded in isolating weed seed at harvest and are now working on the best way of removing it from the paddock. WA company Agricultural Consulting and Research Services, with support from growers through the GRDC, developed a system based on narrow windrowing within an integrated weed management program.
The concept depends on the collection of seed with chaff within the paddock in windrows as narrow as 30 cm, then removing the windrow.
The researchers are now looking at techniques for removing the windrow either by spraying out or by burning techniques involving limited stubble-raking. They have successfully tested a simple prototype windrow sprayer using off-the-shelf equipment ex Hardi Spraying Equipment (WA).
