W203-Annual Bluegrass (Poa annua) Control on Non-overseeded Bermudagrass Athletic Fields

Annual bluegrass (Poa annua) infestations are a common problem on bermudagrass (Cynodon spp.) athletic fields in Tennessee. Foot traffic associated with field use can lead to the development of bare soil areas across the playing surface. During the fall and winter months, annual bluegrass plants can establish in these bare soil areas. Such infestations not only reduce the aesthetic quality of the field, but they can affect playability as well. The shallow root system and bunch-type growth habit of annual bluegrass can reduce traction and cause the playing surface to become uneven.
