Over the past three years we have been collecting data on weather, growing degree days, soil temperatures, and fertility, in attempt to better predict application timing for poa seedhead control. Prolific seedhead production is one of the negative attributes of poa annua, which makes up about 80% of our greens. The seedheads are visually unappealing and affect ball roll, if left untreated. The plants also require a large amount of energy in order to produce these seedheads. This is why I have dedicated much time and research into successful seedhead suppression. It is my hope that better timing of growth regulator applications will limit seedhead production. The plants can redistribute the energy that they would have used in seedhead production into other important plant functions. Healthier plants will be better equipped with the energy to endure the stresses of another golf season. Thus far, seedhead suppression has been extremely successful. The seedheads are visible but they remain...
