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

Product worked okay. It left a slight blue hue on the grass. For me it was more visible when I stepped back from the sprayed-not sprayed line. It did help avoid overlapping spray passes.

A little goes a long way. I’ll drop a couple tablespoons into my backpack sprayer tank mixed with water and the chemical I’m putting down on my lawn. Shows what you’ve already sprayed so you don’t over due the same area. Goes away in about a week. Washes clean from the sprayer tank with just water. Good stuff.

This works well as a marker for spraying lawns /foliage evenly and completely. It can make a mess, however, if it spills in shipment or around your work area, turning everything blue. Adhesion can be improved with a bit of dish soap in the sprayer. This 8 oz bottle is enough for numerous treatments on an average residential yard.

This product is a must when spot killing weeds. It is easy to mix and works really well; cannot be without it! Very pleased with Lazer Blue.

Easy to use. I'd still wear latex gloves.

This is a great product for marking where you have sprayed when I use lawn chemicals. This bottle is my favorite. You do t need much for a single home. This one makes measuring it out each and much less messy than the bigger bottles.

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.

I saw the color changes on my yard. It's a great product.

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.

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,

Works as should, Highly recommend.
