Thank you for your review. We apologize you are not getting the expected results. We would like to help troubleshoot. With the Hi Yield Grass Killer Post-Emergent Herbicide a surfactant helps the herbicide stick to the waxy coating of the weeds and lawn you are applying it to. It improves the effectiveness of herbicides greatly. With this product you would need 1 tablespoon of surfactant per gallon of mixture. Please tell us more about what you are treating for so that we are able to locate a product that will best fit your needs. We can also be reached at 866-581-7378 M-F 9-5PM EST.
