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

It's Blue. Seriously blue. Don't get any on you hands or clothes. Measuring marks on bottle but tough to read because its so concentrated use a flashlight or measure with a 1/2 -1oz scoop/gallon . After spraying it slowly goes away after a few days. Excellent product.

works perfect...just make sure you are careful and dont spill it and wear gloves

The dye worked really good, but the bottle had two issues. The caps are dang near adult proof to open plus you couldn't see how much fluid was in the measuring section at the top. I ended up just dumping some of the dye in my sprayer and hoping it was the right amount. I'll most likely buy it again but get the larger bottle and invest in some measuring cups.

Very easy to use coloring liquid, fast shipping from the seller.

Fast shipping. Great Product.

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.

The image shown does not represent what was delivered. Yes the quantity was correct however, the plastic container is not as clear preventing viewing of the quantity of liquid in the measurement area impossible. Had to use a house hole measuring container to measure the liquid quantity. Extreme care is required with dispensing this liquid into a sprayer as the colorant can easily seem to find its way to outer surfaces making clean-up a chore. The colorant does show herbicide coverage on smaller grass areas however, when spraying large grasses, the colorant effectiveness is not very well observed. IMO not worth the added cost to apply herbicides.

Great stuff! Be careful it will stain concrete or just about anything else it comes in contact with. Definitely allows you to know where you have sprayed your herbicide. Don’t worry, the color only lasts 1-2 days on your lawn after watering.

I get what i wanted

Très pratique pour savoir ou l'on utilise les produits de traitements. La couleur disparait en trois jours sauf sur les murs. ATTENTION Il faudra utiliser un nettoyeur haute pression pour faire disparaitre les taches. Utiliser des gants car sur les doigts ça reste malgré un nettoyage intensif.

Excellent product. Be careful not to spill it. It can be messy.

Works as should, Highly recommend.

I've usually just guessed how much liquid chemical I've applied before but this helped me make sure I got the right coverage. I barely used any in a 15l tank and could see exactly where I'd applied weedkiller. It made the job much easier. I did get some on my shoes but it wore off fairly easily with general wear,
