SpeedZone Southern is not labeled to treat dallisgrass. Dismiss NXT Herbicide is labeled to suppress dallisgrass, meaning that you will need multiple applications and/or other cultural or chemical treatments to completely eradicate the weed. Dallisgrass is a weed that is notoriously difficult to eradicate quickly once it is established. We would also recommend you use Dimension 2EW as a pre-emergent for dallisgrass. Apply Dismiss NXT Herbicide at the rate of 0.117 to 0.350 fl oz./1,000 sq. ft. in however much water it takes you to cover the area. You may need to retreat 4 weeks after the first treatment
