Fusilade II Herbicide will kill Quackgrass in Fescue. Per the label:
Apply 0.07-0.14 oz/1000 sq. ft. (3-6 oz./A) along with 0.25% v/v (1/2 pt./25 gals.) of a nonionic surfactant. Application should be made every 28 days when the grass weeds are actively growing. The higher rates may result in temporary discolorization of the desirable turf with recovery in 10-14 days. Do not apply to desirable turf which is under stress. For best results, make applications in spring and fall and avoid treatments during July and August.
Complete control of undesirable grass may take 1-2 growing seasons.
We also recommend calling your local county extension office as they usually know the optimum times for spraying lawns in your area
