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.
