Mark-it Blue Landscape Dye

MARK-IT BLUE is a concentrated blue colorant designed to provide temporary highly-visible evidence of spray application patterns. MARK-IT BLUE readily dissipates, is non-toxic, and totally compatible with water-soluble solutions. It is ideal for golf courses, parks, cemeteries, athletic fields, and any turf or grass areas — virtually anywhere where spray evidence is needed.

MARK-IT BLUE will not permanently stain vegetation or soil and can be used with all types of equipment.  Not recommended with oil-based herbicide solutions.
