Poa on the Greens

May 17, 2016 Dean Baker

Question from a member: “I know it is early but I was just curious about the patches of what appears to be different grass types on the greens. I assume this is Poa? I recall you mentioned there was a plan to chemically control the return of Poa. Is that still the case?  Will we see those patches go away?”

Answer: You are correct, it is Poa. The worst time of the year for Poa is now as it wakes up well before the Bentgrass does. Chemical treatments & manually plugging of Poa spots begins once the Bentgrass is fully active and growing. The goal with chemically treating the Poa is not to kill it immediately as then we would be left with dead spots. The product is applied in small doses to set the Poa back, allowing the Bent to be more aggressive. This will be an ongoing practice considering the invasion of Poa is endless. 85 % of the fairways & tees are Poa, hence the seeds coming onto the greens... all the time.

Will we ever completely eliminate Poa from our greens? Considering the population of Poa on the entire course, this is a tough challenge. Our goal is to maintain our already high population of Bent on our greens by vigorously managing the Poa invasion. Some Poa spots on greens will be inevitable. Controlling the size of the spots will be what we concentrate our efforts on.
