BASF Turf Mark Blue Spray Pattern Indicator Dye for Grass & Lawns – Non-Permanent, 32 oz

Overview

BASF Turf Mark Blue is a non toxic spray pattern indicator dye designed to visualize where products contact turf. By adding this dye to tank mixes for weed control, fertilizers, or herbicides, you gain a clear blue reference on the lawn that helps you monitor coverage and reduce guesswork.

Its portability makes it suitable for different lawn care scenarios, from large areas treated with boom sprayers to small patches using handheld devices. The blue tint provides visible feedback during application while remaining temporary, as the color fades with sunlight and moisture over time.

Key benefits at a glance

• Enhanced visibility: bright blue marks show exactly where treated areas lie, making coverage easier to confirm during application.
• Prevention of skips and overlaps: the visible cue helps detect drift, gaps, or double passes, improving efficiency and reducing waste.
• Temporary discoloration: fading occurs naturally as exposure increases, allowing discreet treatments without long lasting stains.
• Versatile compatibility: designed to work with boom, spot gun, handheld, and other standard spray equipment.
• Convenient formulation options: available as a premeasured dry formulation that dissolves in the tank, with the option of water soluble packets for quick mixing. Always follow label directions.

How to use

1. Add Turf Mark Blue to your spray tank according to your chosen pesticide, fertilizer, or herbicide product and its label directions.
2. Operate your usual equipment and monitor the blue tint to verify complete coverage across the target turf areas.
3. Finish the application and rinse or wash away; the color will fade over time with sunlight and moisture.

Formulation options and compatibility

• Multiple formulations, including a water soluble packet option for premeasured dry mixing.
• Works with boom sprayers, spot guns, handheld sprayers, and other standard devices.

For lawn pros and homeowners alike, BASF Turf Mark Blue offers a practical signal to guide timing and coverage decisions without relying on memory alone. It is meant to assist, not guarantee, precise results, and should be used in conjunction with proper spray calibration and label instructions.
