With the excess moisture and humidity over the last few weeks, we have seen some Dollar Spot on some tees and the fairways. A week ago we sprayed a control product on all the greens, two tee decks and 6 fairways. We have been monitoring the rest and are ready to spray the remainder if needed. Culturally we have aerated select tees that we feel are most susceptible and applied a low rate of fertilizer to help the turfgrass naturally fight off the disease. Luckily for us, the rain events have slowed down and we have had some cooler temperatures so the disease has not progressed. Usually by this time in the season we have sprayed all the greens, tees and fairways for Dollar Spot which is the most common disease of cool season turfgrass.

As part of our tee renovation projects we have been converting our tees to Dwarf Bluegrass. This grass is less susceptible to Dollar Spot and we have not been able to find any disease on these tees at this time. We now have 25% of our tees converted and plan to do more in the future.
