Its not labeled to target it, but it's also not labeled as safe or tolerant to the product, so you would need to test a small area for tolerance before making broader applications. We do not carry any herbicides for broadleaf weeds in those settings, you may need to reach out to your states Department of Agriculture for farming recommendations.

You could technically mix Quinclorac 75 DF Herbicide with another herbicide such as EndRun. However, keep in mind that Quinclorac works best with a methylated seed oil (MSO) surfactant, such as Prime Source Duo Stick. If you are adding this kind of surfactant with a broadleaf herbicide such as the EndRun, then you may see increased sensitivity on your desirable turfgrass and it does not require one. So we would recommend a small jar test first for compatability as well as to check the turf for tolerance before spraying the entire lawn with this mixture. Or apply in separate applications to avoid possible injury.
