Leopard Greens

There has been a couple questions asking about the yellow spots on the greens.  Those spots are poa annua that we dabbed Roundup on to get rid of.  Early in the season the poa gets a head start on the bentgrass making it easier to pick out the clusters of poa to target with nonselective herbicides.  We have worked hard to keep our greens relatively free of poa through our cultural practices and this is another way to keep poa populations to a minimum.   As you may have noticed some greens have more poa than others and there may seem like lots of spots because they are so noticeable, but the overall population of poa is under 1%.  As the course ages, poa will continue to invade but we will always be trying to keep it out to maintain high quality pure bentgrass greens.  These spots are much like ball marks and will fill in with bentgrass when the turf starts actively growing.
