Speedzone Herbicide and Avenue South Herbicide have different formulations and some different active ingredients, primarily since Speedzone cannot be used on some warm-season turfgrasses such as St. Augustine. If you are in a southern state with a warm-season grass, then we recommend using Avenue South instead for listed broadleaf weeds since it is much safer on those more sensitive grasses. Avenue South has limited residual activity as well. Please refer to the product labels for complete instructions.
