What is #PoaDay?

 #PoaDay is an annual event hosted by members of the turfgrass and ornamental weed science team at the University of Tennessee. The goals of the event are to:
  
      • ​Make turfgrass managers aware of the emerging problem of herbicide resistance evolving in turfgrass weeds
      • Educate turfgrass managers about the different herbicidal modes of action available for annual bluegrass control
The event focuses on annual bluegrass control considering that there are more cases of herbicide resistance in annual bluegrass than any other weed species in managed turfgrass systems (Heap 2014).
