How To Get Rid Of Parramatta Grass In Your Lawn

Parramatta Grass in a couch lawn here in Roseville, Sydney.             There is no selective herbicide registered for use on couch, so have to paint glyphosate on each weed, there’s about 300 of them. The process we took was to:
  1. mix up 1 cup glyphosate with 3 -4 cups water with surfactant and blue dye
  2. paint mixture on to individual weeds with a paint brush
  3. wear rubber gloves for PPE and also to stop your hands from being coated with blue dye
  4. the blue dye is handy so you can see where you have applied the mixture
