Drive XLR8 Herbicide Crabgrass Killer is not labeled to control dallisgrass. Unfortunately, there are very few selective herbicides to control existing dallisgrass. Since these plants can have strong roots and may survive mild winters.
Spot treatments with a non selective glyphosate product such as Roundup QuickPRO may provide some knockdown of actively growing daillisgrass otherwise, you may need to dig out the individual clumps.
We recommend using a pre-emergent such as Dimension 2EW to prevent new dallisgrass in the spring.
Drive XLR8 Herbicide Crabgrass Killer is not labeled for crowfoot grass. For crowfoot, it is generally recommended to treat with a pre-emergent product. Something like Ferti-Lome Weed and Feed with Dimension would be an excellent option. This will be used either in early spring or in the fall.
For the weeds that are there now, we would recommend spot treating with a glyphosate product and reseed/sod the areas. This will kill whatever it comes in contact with.
When applying herbicides, including Drive XLR8 Herbicide Crabgrass Killer, it is not recommended to use a hose-end sprayer. It is better to use a hand pump or backpack sprayer to ensure the most accurate application.

The most important factor when planning to tank mix various herbicides is referring to all manufacturer's product labels for tank mixing restrictions. In this case, because Drive XLR8 Herbicide Crabgrass Killer requires the use of an MSO Surfactant like Prime Source Duo Stick Select in order to be effective, it would not be recommended due to the fact that most Turflon Ester product labels advise not adding a surfactant for lawn treatments as this can cause damage to turf grass.
How soon you can apply Drive XLR8 Herbicide Crabgrass Killer after seeding depends on the lawn species you planted. It appears Eco Lawn is a blend of fine fescues and the Drive XLR8 label states to not apply within 4 weeks after seedling emergence of this type of grass. You should wait until the grass is well established and has been mowed at least twice before applying Drive XLR8.
The Drive XLR8 Label does not specifically mention Big Bluestem grass or Indian grass on the label whether it be as a target pest or as a tolerant species to the product. From the links below from the USDA NRCS it states that those grasses are tolerant to most broadleaf herbicides and should not be harmed if product directions are followed and applied accurately. That being said, you can follow the link below to the USDA Service Center Locator to speak with your local conservationist in your region on what works bests in your area and what products they may recommend.
