Will Hi-Yield 2, 4-D Selective Weed Killer kill Johnson Grass?

I was recommended this, yet the label does not indicate that it will. The soil is sandy, there are millions of seeds on the ground from neglect over a couple of years. The area is located just southeast of San Antonio. I have a serious back problem, yet what I have been doing is digging up the plants and any roots and burning them. However, 3/4 of an acre is a large area to dig up. I can't afford to hire a guy to do this as I am on disability, and I have no one who will help me in this endeavor. What is the proper chemical to use, that does not cost an arm and a leg? Thanks for any help you can give this gal with a back problem.


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. You may also contact our Customer Service department at 866-581-7378 M-F 9a-5p EST for further assistance.
