Product Overview
Prime Source Turf Marker Blue Select (formerly known as Prime Source Turf Marker Blue) will reduce both costly waste and unsightly skips with a visual indicator. Utilizing an indicator dye in your tank mix can save you time and money by quickly identifying treated areas while also alerting you to ongoing equipment failure. Prime Source Turf Marker Blue is a non-toxic liquid colorant marker for turf that shows where pesticides and fertilizers have been applied. This colorant helps show the applications to prevent skips and oversprays in one area. It is completely compatible with other water-soluble pesticides and fertilizers. The product dissipates quickly in both wet and dry weather, making it an effective tool to use whenever needed. This is also available in 1 and 2.5-gallon sizes.
Also available is Turf Marker Green Select.
