Will Hi-Yield Crabgrass Weed Control help me irradicate well established crabgrass roots in bare ground?

I live in Central AZ and my new house has a bare ground yard which I discovered is almost completely over run with a very well established underground crabgrass root system that literally is EVERYWHERE in my yard with roots starting from the surface down farther than 1' foot deep. Help!


Hi-Yield Crabgrass Weed Control is a selective pre-emergent herbicide, which would only be used to prevent the germination process of weeds.  You would need to apply a post-emergent herbicide for your well established underground Crabgrass root system.  Since your yard is bare ground without any turf grass to kill, we would suggest a non-selective post-emergent herbicide like Roundup QuickPRO applied to the undesired weeds, or for a larger area Roundup Pro Concentrate would be a good option.
