Marcus from Mount Juliet writes
It is not recommended to use any type of dish soap in place of an actual surfactant when applying a product such as Gordons Trimec Classic Broadleaf Herbicide. This is because dish soaps can be ionic which can react with the chemical in herbicides, it also can leave a sticky residue, and most soaps have a degreaser in them that can burn your grass. Also according to the product label, a surfactant is not listed as needed when using this product.
