Easy to use. Just visible enough to keep from overlapping or missing spots but not too bright. Seems to fade quickly from concrete. I used 1oz per gallon with great results.

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

This product did not show up on my regular grass, it only showed on dead grass. Ok to use it if you are spraying dead areas but useless on live, green lawns and vegetation.

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.
