How do you manage Poa annua?
Most people choose to control poa annua with a pre-emergent herbicide. This is a herbicide that will prevent the poa annua seeds from germinating. For effective poa annua control, apply a pre-emergent herbicide in early fall and again in early spring. This will keep the poa annua seeds from sprouting.
How do you cut Poa annua?
Cutting It Out The best and most effective way to remove POA is by cutting out the POA either with a sharp gardening knife or some sort of other hand tool, such as a trowel. This method works very well for a small amount of POA, but it can be time consuming on a larger scale.

Where can I find Poaannua grass?
Poaannua is found from the Arctic Circle to the equator , says Dr. Zac Reicher, a specialist with the Bayer Greens Solutions Team. “It is more than capable of surviving in a wide variety of climates,” he says. “This is largely due to the tremendous genetic variability of the turf species and its plasticity, or the ability to adapt to its surroundings and cultural management practices. Depending on the climate, Poa may be the best-adapted grass, poorly adapted, or anywhere in between. Furthermore, it may thrive in the summer in some areas, spring/fall in other areas, or all-year-long. Plus, every golf course has a different environment of soil types, shade and humidity. Add to this that all courses have a different level of ‘acceptable’ Poa population and/or performance, and one quickly realizes that Poa management programs vary dramatically from course to course and region to region.”
What is the name of the golf course in Bethlehem, PA?
Lehigh Country Club in Bethlehem, Pa, boasts one of the finest golf courses in the state, a William Flynn-Howard Toomey design. Director of grounds John Chassard has spent nearly four decades in the turf industry, 35 of them at Lehigh. In 1992, he regrassed his greens, replacing the Poa surfaces with bentgrass. But the Poa returned and Chessard is fine with that. “I’m probably a better Poa farmer than I am a bentgrass farmer,” he says. “A lot of it is dictated by the microenvironments on your golf course. The reason we regrassed was because we were doing a bunker restoration and the greens had shrunk somewhat. We wanted to recapture the original size. We had great greens going into that. It takes a while, especially in this climate, to really let bentgrass grow in. You need a good 12 months of growing, which is essentially a season-and-a-half, almost two seasons of growth.”
Is PoA a weed?
In sections of the country where Poa is considered an intrusive weed, superintendents trying to eradicate it understandably focus their attention on their greens. But Young cautions not to ignore tees, fairways and rough areas. “There is such an emphasis on managing Poa in greens that the rest of the golf course can of gets forgotten at times,” he says. “To have a very effective Poa management program you’ve got to manage the entire golf course, not just the greens and tees. Poa can be very easily tracked in from the fairways and the rough surrounding the greens.”
When does Poa Annua grow?
To understand Poa annua, it is best to begin with its biology. This species appears in the botanic literature as a winter annual, which means that it germinates late in the summer and into the fall, lives through the winter as a mature plant, and in the spring it produces a seed crop and simply dies.
How long does PoA seed live?
Preemergence herbicides have long been proposed as the solution and they can provide some control. However, the seed for Poa can live for years in soil and plants will emerge every time there is an opportunity for germination, such as in a cleat mark on a sports field.
Does Poa kill bentgrass?
This product, though, is limited to use in Kentucky bluegrass. It will kill bentgrass and can damage perennial ryegrass and tall fescue. This product does hold some promise for Kentucky bluegrass sports fields, but again, the biotype problem with the Poa is a concern.
Does Prograss kill PoA?
It easily damages Kentucky bluegrass and other species commonly used in sports turf areas. If your field is perennial ryegrass only, Prograss may be the product that you need, but this is rare.
Can Poa Annua survive the summer?
If all Poa annua were a true winter annual, we could control it with preemergence herbicides, but much of it is a weak perennial that can survive the summer. Even where it survives, it is still an annoyance in sports turf because of its difference in color and texture from other grasses.
Is Poa Annua a problem?
This weed could always be found in sports turf areas, but the less-extreme management conditions that predominated on most sports turf through the 1900’s meant that Poa annua was usually not a major problem in athletic fields in most climatic zones. This has changed in the 2000’s, and the greater intensity with which modern fields are managed is ...
Can PoA be used on bentgrass?
