How much do I add?
Yes, you could use the Southern Ag Non-Ionic Surfactant for Herbicides with Tenacity Herbicide for post-emergent applications. You would not need a surfactant when applying Tenacity for pre-emergent weed control only. You should use 1 teaspoons of surfactant per gallon of diluted herbicide, or 1-2 pints per 100 gallons of spray.
