Does it kill Spinifex?
Casoron 4G Herbicide is a pre-emergent herbicide and does not work as a post-emergent to eradicate existing weeds. It is not labeled to treat for Kapok bush or Spinifex. You could cut the woody plants and use Fertilome Brush Killer and Stump Killer to make a direct application to the fresh cut and vines/foliage.
