We do not currently carry a product that would be considered comparable to Pylex Herbicide when it comes to treating for dallisgrass in fescue. Another option for treating dallisgrass in Fescue would be to spot treat the areas with a non selective herbicide and reseed the areas as needed. You can also use a pre emergent to prevent the dallisgrass from coming up in the first place. You could use a pre emergent herbicide such as Dimension 2EW. Please be sure to review the product label for more information and complete application instructions.
