Monterey Mark-It Blue 32oz

This product is FANTASTIC! I was skeptical about this product, but I decided to buy it anyway. I have a really large yard/lawn so when spraying something, I usually cannot figure out where I have done so and where I have not and let me tell you it's as good as all the other reviews say it is! It was easy to mix, I used my Chapin 5 Gallon Lawn Spray and put about 1 once each gallon so I had 5 ounces of it. It was very easy to tell where I have or have not sprayed in the grass. It worked like a charm! The only thing is, one bottle of this will not last long and it is kind of expensive but it works just fine. If you found this helpful, consider leaving me feedback. And if you have any questions, feel free to ask, I'm happy to help.

Since the beginning of this year, I took back the job of treating for pest, weeds and fertilizing my lawn. Until I came across How to With Doc I did not know of your products... They are are all as advertised, simply fantastic.. but you need to do a better job of keeping them in stock.

I use this product for applying weed killer and prodiamine. It works well for marking the location where product has been applied via a sprayer. The recommended dose of 2 tbl per gallon works well for dormant grass. I needed to increase the doseage for areas that had green weeds as it blends into the green.

This stuff is excellent at letting you know where you've already sprayed! Be careful, though, with using it in a backpack pump sprayer that leaks . . . I've gotten a couple of white T-shirts spotted-blue because of liquid leaking from the tank :-p Luckily, soaking the shirt in the sink w/ soap gets it all out . . . so, no long-term damage done. But, that isn't the product's fault . . . this stuff definitely tells you where you've been, and that you are actually atomizing your liquid (important when using a Dial-and-Spray hose-end sprayer).

This product does a great job. The only problem I have is, pouring from the container to measuring cup, it is very hard to keep from spilling!! Clean up is no fun!!!

Used strictly as directed on the label and was unable to see any blue coloration in the treated grass. In my opinion, this product fails to deliver. Would never buy again.

kinda expensive. we use it on a ranch, so need a lot of product. works good, however.

I always use this when I put ground clear on, I can see where I been, makes it a lot easier. The color goes away in a few days.
