Surfactant for Herbicides is a wetting agent with 80% non-ionic surfactant for increasing the penetration, coverage and overall effectiveness of almost any herbicide. Surfactant for herbicides can be used with almost all herbicide sprays including TrimecÂ®, Atrazine, Brush Killer and 2, 4-D Amine.Please check the herbicide product label first to see if a surfactant is recommended.pplication: HERBICIDES such as 2,4-D Amine, Atrazine, Trimec, Brush Killer, Image, MSMA and others: 1-2 teaspoons per gallon of water, or 1 pint per 100 gallons. GLYPHOSATE HERBICIDES (that do not contain a surfactant): 1 Tablespoon per gallon or 2 quarts per 100 gallons of spray.
