Management of glyphosate resistant annual ryegrass on fence lines locations

To examine possible chemical options for controlling glyphosate resistant annual ryegrass on fence lines.

Key messages
  •  Glyphosate was unable to control glyphosate resistant annual ryegrass on fencelines.
  • Addition of other herbicides to glyphosate products improved control, but was still not effective.
  • Two applications of Spray.Seed, Spray.Seed plus diuron or Alliance were the best registered treatments.
