Quackgrass  (Agropyron repens)  ) ) is a perennial weed that propagates by long roots called tillers. It has a long, tapered, blue green blade that wraps around the stem of the plant in a claw like formation. A persistent weed, it is very difficult to pull quackgrass out by hand. A selective herbicide for broad leaf weeds will not control quackgrass. The only solution to controlling quackgrass is to apply a non-selective herbicide containing glysphate to the lawn; this will kill both the lawn and the quackgrass. Follow the label carefully and reseed after the recommended waiting period. Early fall is a good time to plant grass seed. Quackgrass is a persistent weed that requires drastic measures to control. A second application of non selective herbicide may be required for severe infestations of quackgrass. If this is necessary spot treat by using a foam herbicide or apply herbicide with a paint brush. Check the garden center for weed killers labeled for quack grass. I suggest you take a sample of the weed to your local Extension office for a positive ID and recommended control.
