Notes from the Anthem Greens Committee
Every week, Golf Course Superintendent Cory Wood sends out a briefing to keep Club management informed of what his team accomplished during the two-day closures. Here is his latest report on last week’s closures.
The following is a quick synopsis on what my staff was able to accomplish on the two day course closures this week. Our first priority was to spray the transition aid herbicides on all remaining ryegrass and poa annua. This year we decided to spray three different chemistries of herbicides depending on weed pressure and location of spray. On Persimmon, because of the greater weed pressure, we applied a broad-spectrum herbicide that will not only eradicate all cool season grasses, but will also eliminate broadleaf weeds. Over on Ironwood we sprayed two different chemistries of herbicide depending on the proximity to the bentgrass. Reason being is that the herbicides that are the most rapid and effective for ryegrass (and bentgrass) removal have a tendency to move with the soil water. With this in mind we sprayed all rough and all areas that slope away from the greens with the herbicide that has the greater efficacy. On the areas that are down sloping towards the greens we sprayed an herbicide that is less effective on ryegrass removal (studies show 65% to 80% control), but does not move with the soil water. In order to accomplish this and not have confusion on what herbicide is sprayed where, we painted lines signifying where to start and stop the respective sprays. Unfortunately, these paint lines will be visible for the next week or so, but it is a small price to pay to ensure no damage to the bentgrass greens. Any areas of ryegrass that were too close to the putting surface to safely apply an herbicide will be transitioned through mechanical means (mowing heights and verticutting).
The second priority that my staff was able to accomplish was verticutting all tee pads and collars on both courses. This serves three purposes, first of all, the verticutting will remove a good portion of the dead decaying ryegrass on the areas that have already started to transition. Second, it will open up the canopy of the ryegrass (Ironwood collars) to allow the Bermuda grass to better compete. And finally, the verticutting will actually stimulate the Bermuda grass and encourage it to spread.
Additionally, my staff was able to redistribute sand on greenside bunkers #1, #11 Persimmon & #10, #1 Ironwood to achieve the 3” depth on the bunker faces to help with the plugged lies some of us have been experiencing. All of the rough and bunker surrounds were mowed down on Persimmon to a height of .750”. Ironwood is mowed down 1 through 5, and 10 through 18. And finally, were able to trim a good number of trees that were interfering with travel along the cart paths.
We will continue to forward these progress reports throughout the summer as we rotate the courses to perform important maintenance tasks. As always, if you have questions, feel free to write the Committee at firstname.lastname@example.org
