Liquid Harvest Lazer Blue - 32 Ounces - Concentrated Spray Pattern Indicator - Perfect Weed/ Fertilizer Marking Dye, Turf Mark and Blue Herbicide Marker

I recently purchased the Liquid Harvest Laser Blue Concentrated Spray Pattern Indicator (32 oz), and I couldn't be more impressed. The product quality is exceptional—the concentrated formula is clearly manufactured with careful attention to consistency and performance. Mixing and application were quick and effortless. The concentrate dilutes easily to the proper ratio, and the spray solution worked flawlessly right out of the bottle. The bright laser blue color provides excellent contrast against foliage, making spray coverage immediately visible in the field. Performance-wise, this indicator delivers every time. It provides smooth, even color distribution and produces consistent, highly visible marking that helps eliminate gaps and overspray. The dye maintains its visibility throughout the application without fading prematurely, ensuring accurate coverage tracking from start to finish. The overall effectiveness and value exceeded my expectations, especially for the price. The 32-ounce concentrated formula goes a long way, making it an economical choice for both small-scale and large-area applications. I'd highly recommend Liquid Harvest Laser Blue to anyone looking to improve the accuracy and efficiency of their spraying operations—whether you're applying herbicides, pesticides, fertilizers, or other liquid treatments. It's an essential tool for precision agriculture and lawn care professionals.

Awesome product! Used with my herbicide and surfactant this Spring to help eliminate the new weeds. Picture says a thousand words! Followed the directions and it helped me get an even spray on the entire half acre. Watch out, this stuff will stain your fingers, feet, whatever it gets on. It soaked through my boots a little and it looked like I was turning into a Smurf.

It works great, I use this as marker for my sprayer and using just 0.25oz per gallon clearly mark the application zone, I used this with a Fertilizer and Nutrients mix and now im sure I'm not missing any spot, also used for spot treatment of weed and making sure im not missing areas or double dipping other areas, in general is great, also is water soluble so is easy to clean, and I though it would look blue on the lawn but actually makes the lawn look greener, so it does not have an unnatural finish

Works great but you have to be VERY careful not to spill any … it gets everywhere. Use recommended amount in water and no more. Where rubber boots and rubber gloves and old pants you can throw out. You dont want to put the pants through your washing machine ( ever). Prepare your tank sprayer batches on the lawn… doing it on driveway will create a mess not easy to clean. Allowed me to put an accurate uniform application of pre emergent for the first time ! I’ll use it again for sure .

Yes buy this. Makes it super easy to see where you sprayed so you don’t waste expensive product. Color easy to see. Sprayed nicely. Easy to use.

This stuff works good, but it also turned our atv blue. Fortunately it washed right off. I could definitely see where I sprayed!

I wouldn’t buy this at first because “it was too expensive” but after missing a lot and overspraying others we purchased it. It’s so great to know where you’ve been. The blue dye shows up well and we had enough to do 3 25gallon tanks with plenty of color. It’s a game changer for sure.

Works Great, the color helps identify where I haven’t sprayed. Make sure to use gloves it gets very messy but it’s very easy to use. If you go by the directions.

J'ai testé ce produit sur différentes mauvaises herbes de différentes tailles et .... excepté le fait que ça est donné une couleur bleu au sol ca n'a absolument rien fait !

J'ai suivi les recommandations.Le colorant bleu est bien visible. Les mauvaises herbes sont toujours là et rigolent. PRODUIT INEFFICACE, A FUIR!

Très déçus du produit ça n’as rien fait même après deux passage Produit nil
