It’s blue for sure.

good dye
By Jack on 06/16/2025
I didn't think there was much difference between dyes, until I ran out of this and bought something else. The other dye bottle cap leaked even when tightened securely (what a mess), it took about 5 times as much dye per gallon to see it the same, and it didn't have the built-in measurer.
Great Product

I’ve been having trouble controlling a fungus in my lawn. I treated it for an entire year and it seems to have moved, but didn’t go away. I knew the pellet antifungal went on evenly. I did not know the the top rated liquid dispersing tool was not consistently emitting until I included the blue dye. It was really eye opening.
Should have done this sooner

I've thought about using an Indicator Dye for years, but just now bought some. It made spraying a herbicide so much more efficient by showing me the areas I missed the 1st time. The dye faded within a couple of days without staining my concrete driveway. I'll use this from now on.

Blue everywhere it touches
By Mike on 08/09/2024
It works well in marking treated areas. Does not seem to interfere with chemical effectiveness of treatments. Will get blue everywhere it touches including your hands, clothes, and countertops. Difficult to remove from skin and fingernails. I do recommend it, just be careful when handling.
Works as expected

Turf Mark kept the job on track
By Bill on 03/11/2024
Product works excellent to keep you on track when spraying from a 2 gallon pump up hand sprayer. Treating a field for leaf cutter ants can be a little disorientating when trying to circle a colony with a non- detectable. The dye will help you see what you have treated so you can get optimum coverage and know where you missed.
A must for large areas

it marks
By Ron on 09/22/2023
just used a ounce in two gallons of round up was interesting to see how I had been going to fast so had to slow down it marked everything it got on but seemed to wash off later two days later it rained real good most of it had disapeared and soon more rain took care of the rest so it did not stain the vinal fence or the pavors it was nice being able tosee where I had been and how the coverage was going was ablee to apply a littl more to areas and it worked a lot better I did not have to reapply the round up later to spot treat
used twice the recommended amount just to barely see it
By David on 07/28/2023
I had to use twice the amount just to be barely able to see where I sprayed, so I got half the coverage I expected. Followed the instructions for the square footage of my yard. At least it did disappear quickly from sidewalks and driveway.

Turf Mark Blue Spray
By Ron on 05/20/2023
Never used a marking substance before. Not really needed for my boom sprayer, but for spot spraying, the Blue Mark is ideal. Once I tried it, I'm sold on future use. Initially, I mixed a blend following the recommended ratio. However, I experimented with less, and the Blue Mark was still evident. As advertised, the Blue Mark disappears in a day or two. I recommend use and will purchase again.
Messy but effective.
By Walter on 04/28/2023
I give the product a four star. It's messy. The blue dye marks everything including the turf. It is essential for application. The markings keep me moving and covering untreated areas. It is well worth some hassle to do a more effective job.

Great for spot staying
By Luke on 06/10/2022
Used this product in my 25 gallon tank I mount on my suede by side.. it doesn't work very well at marking your yard through the boom sprayer which is what I wanted it for. It does work great shooting it through the gun. I don't think yard sprayers put out enough liquid for it to color the yard. Not the products fault in any way.
Good stuff
