Mark-It Blue Colorant - 8 oz

Mark-It Blue Colorant is a concentrated blue colorant designed to provide temporary highly-visible evidence of spray application patterns. Mark-It Blue readily dissipates and 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.
