Does Drive XLR8 Herbicide Crabgrass Killer contain quinclorac?

I was told to eliminate "creeping charley" To get product that contain this chemical.


Drive XLR8 Herbicide Crabgrass Killer contains Quinclorac 15.93%. Drive is not labeled to treat creeping charlie. Tenacity is labeled to control Ground Ivy "Creeping Charlie" as post emergent control. We highly recommend using a temporary turf colorant like Turf Mark Blue so that you can see where you spray with the Tenacity to avoid overlapping. Tenacity is a great product, but also a very strong product so too much overlapping or mixing the product too strong can cause temporary damage and whitening to your turf around the ground ivy. The color will come back in the lawn after 3-4 weeks but to avoid this potential problem it is best to use a colorant to make sure no overlap occurs. To get optimum results for post emergent control it is recommended you use a Non Ionic Surfactant in your mixture as well. Please make sure that you check the label to verify that it is safe for your type of turfgrass as you did not indicate the kind of lawn you will be applying the product to. Please let us know if you have any questions.
