  • Apply Weed Weapon Rapid Action ready to use, or Weed Weapon Extra Strength concentrate plus Dye & Stick, all year round. Follow up on re-sprouting areas twice a year.
  • For long term control on non-cultivated areas use Weed Weapon Long Term.
  • Cut down periwinkle and immediately apply Weed Weapon Invade Gel to all cut ends to kill root systems effectively.
  • Small patches can be dug out but ensure all roots are removed as these will re-sprout. Dispose of plant material at a refuse transfer station or burn. Check for regrowth.
