Very hard to see on turf. I even TRIPLED the dosage! Not worth the expense.
Expert response: Thank you for your comments! If you have very dark turfgrass, then it can be difficult to see blue spray indicators on the turf. We do have some other Spray Indicators that you can browse here:

The dye was almost invisible. But it wasn't a fair test. The Prodiamine that I was using had a strong yellow color. Adding the blue colorant to it resulted in a pleasing shade of green almost exactly matching my lawn. By the way, per thousand square feet, the dye cost more than the Prodiamine that I was applying. After this, I will probably track my spraying progress with moveable stakes and watching my wheel tracks.
As much as I was satisfied with Podium,I am dissatisfied with this product. I doubled the suggested amount to use on the second application and the result was still not very visible. It could be that my lawn is very deep green. I saw a red dye somewhere,I'm going to try it.
