Surfactant for Herbicides
Sufactants stop liquids from BEADING up… and let them cover leaves FULLY. Spray water on a waxed car and it beads up. Spray water on an old nasty car and it covers the entire surface. Get it? Basically the surface of most plants is hydrophobic meaning that water does not adhere to it. A surfactant removes surface and allows it to spread out.
This is the product Doc uses: Order the gallon… it does not GO BAD over time.
Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.
