March is here and we are extremely busy at Golf Maintenance.  I thought I would post this picture of a green (not Wolf Laurel) with poa annua seed heads.  Poa annua is considered a weed, but at Wolf Laurel with our greens comprising more than 50% poa we maintain it,  as removal would be nearly impossible and expensive.  Poa Annua produces a flower (seed head ) in the spring, this uses up carbohydrate reserves in the roots and makes the plant more susceptible to drought and disease come summer.  It also creates a bumpy, uneven playing surface in spring.  Our job is to hopefully keep the plant from producing the ugly seed head by using plant growth regulators (PGR) and thus making a healthier plant this summer.  We just applied a combination of Primo (PGR) and Proxy (PGR/herbicide) to reduce the number of seed heads on our greens.  Timing is key with this process as you want to catch the seed head in the boot stage (before it emerges) and three applications two to three weeks apart are necessary.  75% control is the best case scenario with 60% being more realistic, but a process that is well worth the try.
