Luke from San Diego, Ca writes

Is Certainty Herbicide - 1.25 oz. labeled to be used on Turf Type Tall Fescue to treat for quackgrass?


Certainty is labeled to control quackgrass and but is not labeled for your tall fescue. Unfortunately, there is not a product that will kill quackgrass without also killing the tall fescue. The best treatment is spot treating with a glyphosate product like Roundup QuickPro and then reseeding after 2 weeks.
