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

Works as advertised and makes knowing what you have sprayed obvious. Amazon needs to pack for shipping better. The bottle was just thrown in an oversized box. The bottle should be in a plastic bag so that if it leaks, like mine did, it stays in the bag because the concentrate really stains.

It makes liquids blue. Does what it says. Washes off with rain. A little bit goes a long ways. Great for spot herbicide spraying.

A must have to spray anything on the lawn. Will save you money by showing exactly where you’ve sprayed and getting rid of overlaps.

It does stain concrete and leather just as the instructions tell you. It’s biggest problem is that even after you put the cap back on it, the container tends to leak. It needs a gasket or something on its lids to prevent it from leaking if you squeeze the bottle even with the cap screwed on tightly.

I used this when killing my existing lawn before reseeding, and it worked really well. The dye made it easy to see exactly where I had sprayed and helped me avoid missing spots or accidentally overlapping too much- the area circled in red is where I sprayed herbicide with the dye mixed in. A little goes a long way, so you don’t need much to get color coverage. I did get a little on the concrete, but after about a week you could barely notice it anymore. Overall, this made the lawn-kill process much easier and gave me confidence that I was getting even coverage. Very effective and a great product for anyone doing their own lawn renovation.

The bottle needs work. I think it is nice they tried to make it measurable, but it just spills out and gets all over things. I think just a regular bottle to pour out will be fine. Use a little, use a lot, not going to hurt anything. But like other photos showed, it makes a mess. Otherwise, worked as intended, made marking where I sprayed the lawn easier.

Very Good product in which it leaves a dye to show the areas you covered. Last couple of days with gradual fading with the sun and general weather conditions. Use Cloths you don’t care about in case you get dye on you. Wear gloves.🧤

Purchased this prior to the beginning of September to perform maintenance on the lawn. The blue dye helps to identify where I've sprayed and to ensure I get the trouble spots covered with weed maintenance. I look forward to a few dry days to get the application down.

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.

I get what i wanted
