Spray Indicator XL marks where applicators have sprayed with a temporary and highly concentrated colorant. Using Spray Indicator XL will help to drive down your costs of chemical application by reducing skips and oversprays. Spray Indicator XL is temporary and will disappear quickly in dry or wet weather. Spray Indicator XL does not affect chemical efficacy and mixes easily with water soluble fertilizers and pesticides.
Adds color as expected. I used the lightest suggested color on Zoysia that was still straw colored in February. That was all I needed to spray pre-emergent and Permethrin. Where I spilled some of the solution on driveway, the dark green color disappeared in a few days completely.
we use this product at myrtle beach International airport. I am very well pleased with the color and you don't have to worry about too much added to mix. sunlite will fade it out in a few days or rain. If you cant get back to spraying for a day or two you can still see where you stopped
