MRPOA Decomposed Granite Weed Control Application
Scheduled treatment period: October 16 through October 21, 2026
The McCormick Ranch Property Owners’ Association, Inc. will apply pre-emergent weed control to decomposed granite areas within MRPOA common areas and City of Scottsdale medians maintained by the Association.
Pre-emergent treatment helps prevent the growth of grass and broadleaf weeds and supports the appearance and long-term maintenance of the Ranch’s desert-landscaped areas.
Treatment Schedule
Crews will begin in the northern Ranch, starting in Paradise Park Trails, and proceed south throughout the treatment period. Work is expected to conclude in the Paseos, including Paseo Village.
Applications are generally performed during the early morning or midday, when winds are typically lighter. The schedule may change due to weather conditions, wind speed or wind direction.
Green Application Dye
The application solution contains a temporary light-green dye. This marker allows crews to see where the product has been applied, promotes even coverage and helps prevent over-application.
The dye will fade naturally after application.
Safety Information
The pre-emergent product is registered with the U.S. Environmental Protection Agency under EPA Registration No. 53883-429 for the pre-emergence control of grass and broadleaf weeds.
Applications are performed under the supervision of licensed, bonded and insured contractors. Safety Data Sheet information is available at the MRPOA office.
As a precaution, residents and pets should avoid newly treated areas for 48 hours following application.
Watch for Signs
Temporary notification signs will be posted at major public entrances while treatment is underway. Signs will be removed after the applicable precautionary period.
