Hi-Yield 2, 4-D can be used on established fescue grass, or grass that has been mowed at least twice.
Hi-Yield 2, 4-D Selective Weed Killer will target broadleaf weeds such as dandelion, plantain, and chickweed, and is made to be used safely in many types of turfgrass, so it will not be effective for eradicating Johnsongrass. We are not sure if you need to kill the Johsongrass in a turf area or around ornamentals, so it is hard for us to make a recommendation. You can use a grass killer such as Grass Out Max to kill Johnsongrass around listed ornamental shrubs and trees, but it is not safe to use in your turfgrass. Otherwise, you may need to just spot treat with a non-selective herbicide such as RoundUp QuikPro, and then re-seed the turf. There are also pre-emergent herbicides for Johsongrass, but we would need to know the type of turf you have to make this recommendation. Surflan AS is a popular choice for listed warm-season turf.
