PHOTO quiz answers John Mascaro President of Turf-Tec International PROBLEM A The indentions on this golf green are actually cow divots. This golf course in Idaho has a summer pasture located in the foothills above its sixth and seventh holes. One day, the rancher was moving cows on the pasture and some of them strayed onto the unfenced course. This is not the frst time that cows have wandered onto the course; however, this is the frst time that they have caused any damage. On this occasion, the rancher saw eight or nine cows standing on this golf green and was in the process of herding them back to the pasture when they got spooked. Apparently, the optimal cow removal technique (if you ever fnd cows on your green) is not to spook them, as they tend to run and will cause much deeper indentions as they run across your green. Two other greens also had damage, but not as signifcant as the one in the photo. There was also some fairway damage and free fertilizer left behind as well. The majority of the hoof prints were repaired with ball mark repair tools and the worst ones were replaced using a cup cutter.

PROBLEM B These brown concentric circles are not the result of a new disease; instead, they are the result of cup changing. As the superintendent was inspecting the golf course one morning, he noticed these odd circles on several of his greens. He immediately recognized that they were located in the area where the prior pin placement had been located, so he had a pretty good idea of what caused it. This course uses a fve-gallon bucket as a carrier for the cup-changing tools. As it turns out, an employee had used the utility vehicle one day for spraying weeds with glyphosate, and apparently a small amount had spilled into the plastic bed liner of the utility vehicle. By the end of the day, that material had dried up so the crew member did not bother to wipe out the back of the cart. The following day, the same employee loaded the cup-changing equipment and fve-gallon bucket into the cart and performed his usual cup-changing duties. After the bucket was placed on the frst green, the bottom got wet from the dew. When the bucket was placed back in the utility vehicle, it re-activated the chemical and transferred it to the bucket and onto several subsequent greens, leaving this brown concentric circle pattern. Fortunately, the areas grew out in about fve days and no follow-up work was needed.
