Non-Chemical Approaches to Managing Annual Bluegrass (Poa annua L.)

Creator:: Cain, Alyssa B.
Abstract:: Annual bluegrass (Poa annua L.) is a prolific annual grassy weed that can be found worldwide in most landscapes. Known for its ability to produce seedhead at low heights (0.32 cm), thrive in over-maintained areas, and germinate anywhere, annual bluegrass is a highly invasive weed. Due to annual bluegrass’ persistence,...
