When To Apply

Turf Marker Blue Select™ should be used anytime you are applying water-based herbicides, fertilizers, or pesticides and need a clear visual guide to ensure even coverage. Apply it to dry turf for best visibility, and ideally when conditions are calm to avoid drift that could mark unintended areas. It works well in both sunny and overcast conditions, and the color will naturally fade over time.

PRO TIPS

  • Shake well before using.
  • Turf Marker application rates will vary depending on turf color, turf height, and spray application rates. For optimal rate application, experiment with the volume of spray solution and rate to determine what is functional and economical.
  • Use 1/6 to 2/3 fl. oz. per gallon
