Liquid Harvest Lazer Blue Concentrate Spray Pattern Indicator 8 Ounce Surfactant for Herbicides Non-Ionic 8 Ounce

Tried on my very weedy yard and it killed/turned all crab grass white and really showed off how many weeds I had. Didn't kill grass, only killed weeds.

Didn't know how useful this stuff is until I tried it. It takes the guess work out of spraying a area... the surfactant holds the products on the plant leaf longer to absorb the product...thus making it more effective.

Sticker surfactant seems to help herbicide adhere to clover and creeping charlie. Both are EXTREMELY difficult to retain herbicide droplets because their leaves just let the droplets roll right off. Thus making the application of spraying the herbicide a costly, worthless & frustrating endeavor.The negative is that the blue Laser dye to mark what’s been sprayed is very soon indetectable to sight. It’s so close to the color of Kentucky Bluegrass that the color difference (even as one is applying it) does lessen my rating for the combination purchase. By the way, I DOUBLED the “dose” of the Laser Dye due to my prior experience that it was too light to detect. I choose to apply this after the THOUSANDS of little white petals have fallen from some flowering trees in our 1/2 acre front yard. The white petals actually retain the blue color. There are not many choices for herbicide dues out there, so I have chosen to stick with this product.Like I’ve said though, the surfactant seems to help with weed leaf adhesion.

I needed to spray some larger areas for weed control. This made it much easier to see where I had already sprayed. The surfactant really seemed to help the weed killer stick to the weeds and not run off.

Good

Love these 2 together they work well, and make your life easier.

Work as advertised and a great deal

The surfactant does a good job helping penetrate the grass, and the dye helps show where you’ve sprayed. However, the dye is a nightmare to deal with—it stains your skin and is tough to remove. It’s also a bit hard to see on the grass, even with a normal mix. I might stick to just the surfactant and skip the dye next time.
