It doesn't happen by accident

The golf course was seeded, beginning on Labor Day of 1989.  30 years later, there is less than 1% Poa Annua in the fairways, and that didn't happen by chance.  For many years, we have successfully used a combination of maintenance practices, along with a post-emergent herbicide to control Poa, and prevent it from invading the fairways.

However, it now appears that we may be seeing some resistance to this herbicide developing.  (Resistance can also occur with insecticides, fungicides, and human medications--such as antibiotics.)  We are therefore looking at alternative ways to prevent Poa from gaining a foothold.

This year, we have added a late summer pre-emergent herbicide application to the fairways in an effort to prevent Poa.  This is one of  the products we typically use in the spring to prevent Crabgrass.

While there is no perfect grass for this region, Bentgrass is definitely a much, much better choice for fairways than Poa, and we will continue to fight to keep the fairways Poa-free!
