Liquid Harvest Lazer Blue Concentrated Spray Pattern Indicator - 32 Ounces - Weed Spray Dye, Herbicide Dye, Fertilizer Marking Dye, Turf Marker 1 Quart (32 Ounces)

we all know that these blue dyes are supposed to be concentrated, but this one is super concentrated because I hunted down the Bang for my buck and coverage that I could.Many dies, say that you can see them but often when you mix at the ratios, they say they don’t do quite as well as a job as they said they wouldthis product has not let me down yet and one hint is to use a surfactant so that not only will you die stick better but so will your chemicals that you’re spraying on your plants. Remember surfactants take away the waxy coatings on leaves so that instead of water beading up and running off, It tends to stay on the leaf and allow absorption betterI highly recommend you wear gloves with this and I don’t mean cotton. You need to wear a water or chemical resistant glove even when you’re mixing it because one drop of this goes a long way on your skin and as much as I have had Smurf butt from leaking backpack sprayers, I have learned to do everything I can to keep this product and the chemicals that is mixed with away from my clothing and skin.I’ve even gone as far as to wear high waders To keep my occasional tall weeds from getting stuff on me and it also helps to keep any back spray offIf you look at the wonderful photo of my hand, you will notice it is slightly stained, and it isn’t. The guy that I worry about is the chemicals that went along with the dye as they are Herbicides.I had a brand new battery powered backpack and as much as I thought it was not going to leak the handle did a really bad job and before I knew it I had a blue hand, so always test your equipment without clean water for leaks because this stuff can be very messy but on the good side, after soaking in the bathtub for an hour and a half and scrubbing the mess out of my hands the dye removed itself or neutral, and all is good in paradiseGreat and I highly recommend it and my favorite part. Is that only last about half a day and then it disappears unless you get it on vinyl siding that’s old that might take another day.Just read and follow the directions thoroughly because mixing the chemicals are very important. Otherwise you might be wasting your expensive chemicals because you can’t see where you sprayed and overspray is not a good thing either.I hope this helps you and I wish you the best of luck when you’re using this as it is an amazing product when use properly. I highly recommend it and it lasts a long time and usually at least a couple years just sitting around out of the sunlight. I have no idea it freezes or not so I would definitely tell you if you’re going to keep this somewhere up north where it gets super cold in the winter, I would definitely put it in some type of plastic 1 gallon bucket in case he had a freeze in the plastic cracked and that decided to leak out at least it wouldn’t spill over You could use it again when it warms up

Easy to see and once you figure out how lean you can mix it lasts a long time.

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 !

I use this with milestone and/or Garlon 3A - Both of which are mixed with water, marks well and disappears after a few hours. Great for marking while foliar spraying.

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