Spray solution blue colorant that indicates where you have applied a chemical spray. Works great with Roundup or Remuda and other herbicides as well as fertilizers and insecticides. Avoid skips and overlapping. Washes off without staining, is non-toxic and dissipates with sunlight.
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.
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.
Product seems to be satisfactory. Packaging is pretty weak and thin. Dropped a jug and it split open and went everywhere. Quite a mess and expense due to lost product. Not sure if I'd use this again or not.
Most colorants do not have any toxicity to aquatic life or any area you are treating. The Mark It Blue does not state specifically whether you can use in in an aquatic area. You can contact the manufacturer to see if it will meet your needs. Monterey Lawn:1-559-499-2100
