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

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.

Great to see where I sprayed weed killer! The Liquid Harvest Lazer Blue Spray Pattern Indicator is an essential tool for precise spraying. The vibrant blue color makes it easy to see coverage and ensures even application, reducing waste and missed spots. The 16-ounce bottle is concentrated, offering plenty of uses, and it mixes easily with water or other solutions. Ideal for farmers, gardeners, or anyone needing accurate spray patterns for herbicides or fertilizers.

Anyone who has ever sprayed liquid herbicide (or any chemical) over a large area of ground will appreciate the problem. It is tough to remember exactly where you sprayed and didn't spray. You end up with either large gaps, or areas sprayed multiple times, or both. This product helps out quite a bit. === The Good Stuff === * Once you get the hang of seeing it, the blue is distinguishable even on green grass. It helps a lot if there are patches of bare ground, or some dandelions or other flowering weeds, but you can see the blue even on grass. It helped me a lot wear polarizing sunglasses. * I mixed it per the label instructions. I suppose a little extra would have helped things along- maybe next time. * Cleanup wasn't as bad as I feared. The instructions mention bleach, but I just ran a little extra plain water through my backpack sprayer, and the blue dye cleaned up. There might be just a slight blue tint to the clear tubing lines on the sprayer, but it gives the thing a little class. === The Not So Good Stuff === * This stuff should really ship with a box of surgical gloves. The instructions say the dye will wash off skin with repeated washings, but I suspect it really means that once the skin wears away, the dye goes with it. And if you get it under your fingernails....well, good luck. * I was not a fan of the bottle. It didn't pour real cleanly, meaning the stuff dribbles down the side of the bottle. Makes for a real mess. A squeeze bottle, or some sort of pump would have been appreciated, even if it added a few cents to the cost. === Summary === In the end, the product did what it claimed. There are a few things that could have been better, but it solved a problem, and probably paid for itself in less double spraying. I would have much preferred a brighter color (yellow or orange), but I suspect the blue dye was the easiest to make work. If you are colorblind to blues and greens, don't even bother.

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.

This is an excellent marking dye that can be used with a variety of sprays used around the yard. It fades within a few days and you can vary the concentration based on your preference - I use a little less dye than recommended so it isn’t as noticeable but I can still tell where I’ve sprayed. I purchased it while fighting a weed problem and found it helped reduce the amount of herbicide I needed to use by identifying weeds that have already been sprayed vs ones that haven’t.

Pulled some of the wording from my mesotrione review from this same company, where I used this dye with the meso and the surfactant too: .... "Another thing I want to add is that for my 1 gallon sprayer, I used half a teaspoon of the Mesotrione, following as accurately as possible the mixing instructions, and also did follow the surfactant and dye instructions too, though I accidentally tipped the measuring-pouring tip combo too much on the dye product and more came out into my sprayer bottle. Well, that turned out still to be helpful anyway to increase the easy view of where I was spraying, and it only dyed my sidewalk a little bit, which faded very well over the next few days too and washed off better with some sprinkling going on. Overall, all 3 of these products were great results to me, and there is enough of each of them left for probably years to come, since I don't have a large area of crabgrass to even treat."

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.

Excellent
