Weeds have a waxy coating on them and it beads up the liquid you spray. Surfactant breaks the surface tension and allows the liquid to stay as alot more fine droplets on the leaf and absorb better. I have read that dish soap works. Dye is just to help prevent spraying things twice, or missing something. Im not promoting anything, these are just from my order history. There are tons of options. https://a.co/d/0e2GqYFR https://a.co/d/0eHT5wxC And if you want color, cheated iron will give a darker green. I only add this because I seen it in my order history. https://a.co/d/0hiOt2Yi Welcome to the club.
