Liquid Harvest Lazer Blue Concentrated Spray Pattern Indicator 8 Ounces Perfect Weed Dye, Herbicide Fertilizer Marking Turf Mark and Marker

I was shocked at how much easier this made the job of spot treating for weeds. Since I could mark the weeds I'd treated, it enabled to focus much more clearly on places that I knew for sure I had not already been. Doesn't seem like that would make a big difference, but for me...it did.I did use the product at a pretty strong mix. 1 ounce for a gallon, versus the suggested 1/2 ounce. Thus, your spots may not be quite this blue!

Good stuff. As described marks weed killer area where sprayed so there’s no spraying the same spot twice. WEAR DISPOSABLE GLOVES! As others have stated, the concentrated liquid color is thick and stains easily. Once diluted and applied it fades away which is a plus.Only negative is the bottle with the measuring side. Can’t see the amount because the dye sticks to the sides so cannot see how much is in it. So I just use a small disposable measuring cup.

it does what it says it does, turns your spray blue. but it also turns everything it touches blue mostly because the bottle is pretty nonsensical though, as the measuring side immediately turns blue and you can't see how much you've got in there, and when you tilt it to pour more comes up from the bottom and you're using too much product and likely have it all over your hands. product is great but the bottle gets dinged a star for these issues.

This is the greatest product, when mixing everything turns blue and you can tell exactly where you sprayed!!Love this product!!!!

Although this dye seems a little expensive, I suspect it is well worth the price if it allows the user to not apply spray to an area a second (or more) time. I tried to keep from spilling on my garage floor but spilled in several places anyway. After a few days I was able to wipe it up. I tried using surgical gloves to keep from staining my hands, but ended up with several blue spots on both hands. I used GoJo to try to wash it off my hands, but no luck. I showered after I finished work but my hands were still blue. I then used Aveeno moisturizer on my face and legs and much to my surprise, the blue marks had disappeared!My only regret is that I should have bought a larger bottle of this product, because I ran out befor finishing my work.

I don’t know if you’re like me, but I sure love to get yelled at by my wife for things that I have absolutely no control over. 🙄The 8 oz. bottle that I received does not look like the bottle in the photo. It’s unfortunate because this style of bottle would cut down on the mess made when dispensing the dye. The bottle that I received looks like a smaller version of the 32 oz. bottle.Instead of squeezing the bottle to measure and dispense the dye (like you would do with the bottle pictured on Amazon, I had to measure it the old fashioned way (pour the dye out of the bottle and into a teaspoon). As much as I like old fashioned things, I dislike looking like a Smurf.My bottle was either previously opened or has a crack at the very top of the handle. As soon as I started to take the lid off, dye started to come out of the bottle. Measuring out four teaspoons was a messy adventure that I did not need to have, but since I love to get yelled at, everything ultimately worked out just fine.In all seriousness, be aware that the bottle you receive might not be the style of bottle pictured here on Amazon. Wear gloves and be careful. I feel stupid saying this because it shouldn’t be a big deal pour out of a bottle and measure it. BUT if this process goes south on you, even in the slightest bit, it is messy. The dye gets spread everywhere very quickly and it smears around when you wipe it up.If you get it on your clothes, it comes out fairly easily. We pretreated the stains with Oxy stain remover and soaked the clothes in a bucket of laundry detergent and Oxy Clean before washing. The dye also washes off of your skin easily too, not instantly, but easily.Finally, the product works as intended and it’s nice to be able to see where you sprayed and where you didn’t.

Works well makes it easy to see where u sprayed

As another customer said, the 8 oz. bottle that I received does not look like the bottle in the photo. The bottle that I received looks like a smaller version of the 16 and 32 oz. bottle. There is no provision for easily measuring out 1 oz portions inside the bottle.Instead of squeezing the bottle to measure and dispense the dye (like you would do with the bottle pictured on Amazon), I had to measure it the old fashioned way (pour the dye out of the bottle and into a tiny measuring cup). This was messy and far more inconvenient.So, be aware that the bottle you receive might not be the style of bottle pictured here on Amazon. IF spilled, the dye gets spread everywhere very quickly and it smears around when you wipe it up.Update: I received a response to this review from the seller offering a full refund due to the mixup about the bottles. 10 STAR CUSTOMER SERVICE! As much as I would have liked the bottle with the built-in dispensing feature, the product itself is great and performs wonderfully. And you can't beat the way the company takes care of its customers.
