No waste

It does what it says....
With my Pertatools sprayer I was able to pin point application, with no wasted overlapping or missed spots. You must wear gloves and choose a proper area to mix in but as stated it's not permanent. It does fade.....as for my lawn it returned to normal color after a good soak

Step up weedkilling game

The dye is very potent, wear gloves and be careful of spills. You don't need much to leave clear indication of which weeds have been sprayed and which ones haven't; so no more double spraying some and leaving others untreated.

Impact of the surfactant is less obvious, but assuming it works as advertised, it will improve the exposure of the weeds to the herbicide, leading to more effective weed control of even waxy, herbicide resistant weeds.

Strong dye

As the description mentions, it has 3x more dying power!
It also dissipates in a few days, so it's perfect for applying herbicides, etc.
