been using mark-it blue for about 5-6 years I have 5 acres with a lot of tumble weeds I ad added mark-it blue. Due to the cost of weed killer I started using mark-it blue it saves a lot of $$$ because I do not duplicate spraying the same weeds multiple times.

Only marks dead grass areas

Helpful with herbicide application but hard to see on dark green foliage unless recommended amt is doubled. Even at 2x strength I will get alot of applications from one bottle. Accidentally knelt in full-strength blue dye; worried i would be 'tattoed' for a long time but several hours later nearly all showered off with only a little effort using soapy washcloth.

Mar-It Blue Results

Highly disappointed
By Don on 08/16/2019
Mixed product as directed and it did not mark my grass where sprayed. On my next batch, I doubled the dosage and could barely see where I sprayed. Third batch, I tripled amount and was the same as the second batch. Save your money. I will try another product. I was meticulous in measuring and was using two gallons of water per batch and yes I used tablespoons, not teaspoons. Highly disappointed.

Does the job!!!

I mixed as recommended and it did the job but I wish it was a bit darker and slightly longer lasting as it was already faded the next day and I was going to do another treatment and hit all the spots I missed the first time. Next time I use it I will just mix it at 150% to 200% and see how that goes.

hard to see on green grass

Mark-It Blue
By Deanna on 04/05/2019
This product made it easy to see where I had sprayed a post-emergent herbicide so I was better able to ensure I didn't miss a lot. The product mixed with the herbicide and a surfactant stayed on the ground so I was able to see the area I had sprayed. I'm glad I bought it.
Excellent quality.
