Best for larger residential or small commercial lawns using water-based mixes. Caution: not compatible with oil-based formulations, so verify your spray solution before mixing.
Liquid Harvest Lazer Blue 8 Ounces
This 8-ounce bottle provides a compact option to prevent over-application and detect spray drift. It’s easy to add to a sprayer and works well for homeowners and professional users alike who need a quick, visible indicator for precise coverage. Limitation: smaller volume means more frequent replenishment for larger jobs.

One-gallon bottles suit larger properties and contractors who need extended coverage with a visible spray indicator. Best for professional settings where consistent, wide-area marking is essential. Caution: ensure compatibility with your spray mix since this product only works with water-based solutions.
Adios! Blue Spray Dye Marker (8 oz)
Adios! offers a super-concentrated dye that makes up to 16 gallons of indicator. It provides a bright royal blue color, easy to see on lawns, and quickly fades after 24–48 hours. Choose this if you want a high-visibility mark that does not linger long after spraying. Limitation: color fades, so timing matters for follow-up treatments.
Eco Living Solutions Blue Tablet Dye
These effervescent tablets dissolve quickly in water to create a blue spray indicator, with the benefit of a mess-free and stain-free handling experience. Best for users who want a simple, tablet-based solution that minimizes spill risk and cleanup. Potential drawback: tablet-based systems require a bit more wait time to fully dissolve before spraying.
Monterey Mark-It Blue (8 oz)
Monterey Mark-It Blue provides clear spray identification to help avoid overlaps and missed areas during applications of insecticides, herbicides, and fungicides. It breaks down with heat and light, reducing environmental persistence. Best for long-term marking needs where breakdown is desirable after exposure. Limitation: performance may vary with intense sunlight or heat, accelerating color loss.
