Control Tips

Gusto woody and noxious weed herbicide is registered to control Crofton weed.

When using Gusto in a high volume spraying situation:


  • Thoroughly spray all leaves and stems just to the point of runoff.
  • Spray between Spring and Autumn when the plant is actively growing.
  • Use a high quality wetting agent like Weed Forces Holdfast to improve wetting and herbicide penetration of the plant foliage resulting in superior weed control.

  • DO NOT spray when the plant is stressed (i.e. Drought, physical damage, insect damage etc)
