Turf Mark® by Becker Underwood takes the guesswork out of spraying! It's the proven and professional way to apply liquid pesticides and fertilizers. Universally used by golf course superintendents, grounds maintenance personnel, lawn care companies and sports turf managers, Turf Mark® dissipates quickly in either wet or dry weather, making it the ideal temporary spray colorant. Turf Mark Blue's distinctive color shows you exactly where you've sprayed, preventing skips and overlaps and helping to pinpoint drift. Turf Mark® makes spray applications virtually foolproof. You'll save time and money!

TurfMark is widely used in pre-treatments for termites during the construction of a new home. If you are treating the foundation studs with a product like Boracare which dries clear, an inspector would have no idea where or if the wood was sprayed. With Turf Mark Blue, the Boracare will leave a blue tint on the wood, which makes the pre-treatment easily identifiable by an inspector in the future.

    Well on the +side, it is much less messy than the liquid I have used. On the - side, I had to use 3 tables in two gallons of spray to get enough color to see where I had previously sprayed.

    Turf Mark Blue Tablets

    Worked well, but they took a little longer than expected to dissolve in my weed spray. Next time I would allow 10-15 minutes and then shake vigorously to get even color tone. Great product.

    evidently not for herbicide use

    Used this when applying Dimension 2EW herbicide. Left no markings at all. It says for use with insecticides and fertilizers, so perhaps something in the herbicide prevented it from working.

Does the tint of the Turf Mark Blue Tablets wear off/disappear or is it permanent?

Have been told I have powder post beetles in rear covered porch joists. Wood is exposed, so I would like to not turn the wood blue permenantly. Also, area to be treated is 350 square feet. Terminex wants to charge $350 + tax to treat. Is that a fair price, or should I try doing it myself (estimates of buying bora care, the turf mark tablets, and sprayer is about $175).

The Turf Mark Blue Tablets can turn the wood blue permanently. While we cannot say if we think Terminix is charging a fair price or not for liability reasons we can tell you that if you are willing to do the labor yourself you will save a lot of money.

Can Turf Mark Blue be used w/ sedgehammer to mark where applied?

and....how long will the color stay?

You can use the Turfmark Blue tablets with Sedghammer. Color mark lasts 1-2 days and breaks down in sunlight and moisture on foliage. Rate: 1 tablet per 1-2 gallon (3.8-7.6 ltr) of spray solution.

Blue color tint of Turf Mark Blue Tablets

two answers conflict on color tint wearing off. one says color is permanent and another says it wears off in 2 days. Which one is correct. I want to stain the wood after treating it so do not want to have the blue color change the stain results.


When Turf Mark Blue Tablets are mixed with an herbicide or insecticide and applied to a lawn it will break down in sunlight and moisture within 1-2 days per the label.  If used on wood that is not exposed to the elements it can permanently dye the wood blue.  So both answers are correct; it all depends on the application.
