Why is _Poa annua_ such a problem for golf course superintendents?
_Poa annua_ is an annual bluegrass that favors cool, moist conditions for germination and growth, flourishing from fall to spring. Thus, it has a strong competitive edge over many course turfgrasses, and can dominate a stand of grasses that are mowed closely and irrigated regularly.
Which turfgrasses are tolerant of Prograss EC?
Prograss EC can be used safely on bermudagrass (dormant, overseeded with ryegrass), creeping bentgrass, Kentucky bluegrass, ryegrass, turf-type tall fescue and St. Augustinegrass (established).
Is Prograss EC safe for overseeded turf?
Yes. If safety intervals listed on the label are followed, Prograss EC can be used after overseeding.
