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.

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.🧤

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.

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 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.

THe first order was credited before I received it. I reordered. It came as a bottle of liquid in a cardboard carton. No bag around the bottle. Te bottle leaked. No big deal. When I attempted to use the product the pour cap was stuck because the seal under it was broken. Once I finally got the lid to break loose, blue dye went everywhere. On my garage floor, on my work clothes, all over my spray tank, and on my skin. (You may now call me Grandpa Smurf). As I attempted to follow the directions for measuring the proper amount to pour...once again blue dye went flying. Finally I had my one ounce measured in the pour section of the bottle. As I went to pour the dye into my sprayer I quickly learned that the check valve between the two sections of the bottle (if there ever was one) had failed. SO, instead of adding 1 ounce of blue dye to my sprayer an untold 9LARGE) amount of blue dye ended up in, on, around, and under my sprayer. I tried once again in vain to clean up the spilled ocean of blue dye. Then I went to spray nutsedge in my yard. my VERY BLUE yard. I live about 20 miles away from KCI airport on a main approach path. I am pretty sure I noticed the jets slowing down over my yards to try to figure out why there was a small ocean just east of Kansas City. Hint: If you need to clean lots of blue dye off your skin use baby oil or olive oil. Let it sit there for about 5 minutes, wash it off with a washcloth you don't intend to keep, (unless you're getting married soon and need "something blue" for the sake of tradition). Repeat until you will can no longer get past the front gate bouncer at a Smurf rock concert. It's blue, it's not caustic, it works as stated, the packaging is...well...something between challenging and life altering. Fortunately blue is my favorite color and I'm really liking my garage floor now.

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.

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
