An aggressive perennial grass, Quackgrass reproduces by seeds and spreads by mass of shallow branching rhizomes. It is only fair forage for livestock, but rapidly spreads and takes over an area. It is a nuisance in lawns and home gardens.
Quackgrass is found throughout Nebraska, but it is most common in the northern and eastern portions of the state. There have been no reported infestations in Kansas since before 1986.
Broken rhizomes form new plants making mechanical control of little use. An aggressive cultivation practice will expose roots and rhizomes to drying on the soil surface, but must have succeeding cultivations at intervals of about 1 week.
There are no biological controls approved for use on quackgrass. Herbicide treatments are available.
