The Fusilade product label does say you can use the product on well established Tall Fescue grasses to control other grassy weeds such as quackgrass. For mixed fescue you recommend you contact the manufacturer directly as we do not want to give you inaccurate information. You can reach Syngenta by calling 866-796-4368
