Surfactants In Weed Control. Surfactants help herbicides do their job. When you're trying to kill weeds, you need to add a surfactant to the mix. Technically, a surfactant is a soluble compound that reduces the surface tension of liquids or reduces interfacial tension between two liquids or a liquid and a solid. In other words, it's a linear molecule with a hydrophilic (attracted to water) head and a hydrophobic (repelled by water) end.
