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.

Drive XLR8 Herbicide Crabgrass Killer is generally safe to use around animals as long as they are out of the treatment area while you are spraying. Once the application is dry, it is not harmful to squirrels or other animals.
Only when Drive XLR8 is being applied to established creeping bentgrass is the rate different than for other turfgrasses as listed on the product label. Otherwise the rate is 1.45 fl oz/1000 sqft. The product is absorbed by foliage and roots and is translocated throughout the plant. It should not harm mature trees or desirable plants when used as directed. Generally if you can it is best to use separate sprayers for herbicides and insecticides but if you use the same be sure to triple rinse the sprayer thoroughly have each application of such.
You will need to keep the Drive XLR8 Herbicide out of the drip line of the tomatoes to be safe.
Depending on what you are treating for Drive XLR8 Herbicide Crabgrass Killer can be applied as a spot treatment or broadcast. Be sure that the turf grass you have is labeled as tolerant if you wish to broadcast.
Drive XLR8 Herbicide Crabgrass Killer is not labeled for applications on pastures on crops used for food or feed. Please provide the names of the targeted weeds so that we can offer an alternative option.
Drive XLR8 is not labeled to control quackgrass. We do carry Certainty which is labeled for it. Please be sure to read over the product label to confirm your lawn type is tolerable to the product. If you lawn type is not listed as tolerable and if only a small area of the lawn is affected by the outbreak, spray only the affected area with RoundUp Quick Pro. If the problem amounts to no more than a few spears of quackgrass in an area of your lawn, paint the individual spears with diluted RoundUp QuickPro.
As you probably know, Centipedegrass is a very sensitive species of turf so many products that eliminate the crabgrass and other weeds can also cause damage to your lawn. Hi Yield Atrazine is safe to be used on Centipede and it will suppress Crabgrass but may not completely eliminate it. It will also control a large variety of other broadleaf weeds. Tenacity is a great pre and post emergent herbicide that will control crabgrass along with many other types of weeds without harming your centipede lawn. Make sure to read the Tenacity label very carefully and mix exactly what is recommended as this is a strong product and mis-using it can cause temporary turf injury. When applying tenacity it is highly recommended to use a temporary turf colorant like Turf Mark Blue to allow you to see where you are spraying. Overlapping your application of Tenacity can cause temporary whitening of the lawn as well, but the color will return in 3-4 weeks at most. Please let us know if you have any other questions.
Drive XLR8 is not recommended to be used in a hose end application. The first thing you need to know when using a herbicide such as Drive XLR8 is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and your risk damaging your lawn, use too little and you will not get adequate results. You will need to use 1.45 fl oz per 1000 sq ft. To decide how much water to use, you should mark a 1000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 1.45 fl oz of Drive XLR8 with for each 1000 sq ft that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either rainfall or by sprinkler) following the application.
Since Drive XLR8 Herbicide is a post-emergent herbicide, we want to make sure that we get good coverage of the target plants, and that the application has time to dry before rainfall or before the lawn is watered. Drive should not be watered-in upon application since we want it to stay on the surface of the target plants. Be sure you are using an appropriate surfactant when using Drive, such as Prime Source Duo Stick. You should allow 10-14 days to start seeing results from post-emergent herbicides.
Per the product label on Drive XLR8 you do not want to apply to exposed roots of trees or ornamentals or within the dripline of trees and other ornamentals species, This would cause potential damage to those trees.
No, Drive XLR8 Herbicide is not labeled for fountain grass. We would recommend either manually removing the invasive grass or using a glyphosate product such as Roundup QuikPro.
Drive XLR8 Herbicide should not be used in temperatures above 80 degrees Fahrenheit. You will use 29 fl. oz. in 20 gallons of water. The rate is 1.45 fl. oz. per gallon of water.
Yes, Drive XLR8 Herbicide is labeled for barnyard grass. For spot treatments, the mixing ratio is 1.45 fl. oz. per gallon of water. Be sure to use a methlyated seed oil surfactant with this product to ensure that you receive the best results.
Per the manufacturer BASF, when using Drive XLR8 Herbicide Crabgrass Killer they recommend using a methylated seed oil like DyneAmic Sufactant not a regular non-ionic surfactant.
Yes, Drive XLR8 Herbicide and Gordons Trimec can be mixed and sprayed together. Be sure to do a small tank mixture first to ensure there is no clumping between the two products. Also, be sure to use a methylated seed oil surfactant, such as Duo Stick, so that the weeds are killed more effectively.
Drive XLR8 Herbicide Crabgrass Killer will not harm established Tall Fescue. It can harm Fine Fescue and also potentially Dallisgrass.
Unfortunately, Drive XLR8 Herbicide Crabgrass Killer is not labeled to kill Japanese stiltgrass. We would recommend a product like Bonide Over the Top II Grass Killer instead. This would not damage the non-grass ornamental plants you have while taking care of the stiltgrass when use based on the product label.
Normally we suggest giving the product 3 weeks to see results using Drive XLR8 or any selective herbicide. Depending on if you are spot treating or broadcasting the solution determines the mix rate.
Spot Treatment: For a 2 gallon sparyer, Mix 6 tbsp + 3 tbsp of Adjuvent. Apply at the rate of 1 gallon per 1000 sq ft. (1 tablespoon = 0.5 fl oz (0.25 lb ae/A)
Broadcast Application: 1.45 fl ozs per 1000 sq ft / Methylated seed oil at 0.55 fl oz per 1000 sq ft (0.75 lb ae/A)
.
When using Drive XLR8 Herbicide Crabgrass Killer the active ingredient quinclorac has dissipation values that can range from 60 to over 500 days. Because quinclorac does not bind well to soil, some dissipation noted in field testing could be due to chemical testing. The persistence hazard of qunclorac is rated high (likely to take over 60 days to degrade to half of the applied concentration). We would recommend waiting an entire season before any grazing took place on the area that was treated for this reason.
