With that weed free zone and atrizine mixture, is substituting Dawn the same as the weed sticker? I think I remember hearing something about that, or am I thinking of something else?

Many do use Dawn detergent as a surfactant and it’s better than nothing, and I’ve used in a pinch, but of course it’s foaming and I’ve not see definitive proof that it is a non-ionic surfactant as opposed to an ionic surfactant. That said, non-ionic surfactant (spreader/sticker) as recommended is cheap and specifically formulated to be used with herbicides, just seems prudent to me to use a spreader/sticker formulated to be used with herbicides to get the best performance out of those herbicides, which are much more expensive.
