Town will begin applying herbicides to prepare for winter weed management

CAVE CREEK – In the Town’s ongoing efforts to reduce fire risks by managing invasive plants, Cave Creek Public Works Department will begin applying herbicide to town-owned properties over the next few weeks.

The Town will use pre-emergent herbicides in order to get ahead of the winter weeds, especially Stinknet which has contributed to a particularly devastating fire season for the community. These herbicides will assist in combating Stinknet and other invasive plants that threaten the Sonoran Desert’s fragile ecosystem.

Town employees will begin applying the brand name herbicides, Quali-Pro and Ranger Pro, beginning on September 09, over the next several weeks. The herbicides contain a yellow dye that marks where the chemicals are applied that residents may notice along roadways.

The Town wants to make residents aware so people with underlying health conditions, or anyone with sensitivities to herbicides can take necessary precautions for themselves or their animals.

The following roads will be treated with herbicides over the next few weeks:

  • Cave Creek Road
  • Carefree Highway
  • 26th Street
  • 32nd Street
  • School House Road
  • Spur Cross Road
  • Fleming Springs Road
  • Highland Road east of School House Road
  • Galloway Drive north of Cave Creek Road

For anyone who would like more details about these herbicides, the Material Safety Data Sheets (MSDS) can be viewed online for Quali-Pro and Ranger Pro.

The Town would like to remind the community that now is an optimal time to apply a pre-emergent herbicide to your property before Stinknet begins to germinate, which is typically in November.

Cave Creek has gathered resources on its website for anyone needing guidance on how to manage Stinknet on their properties. Maricopa County has an informational brochure available as well.
