Program '11 Update: More Dollar Spot and Brown Patch

Dollar spot pressure has continued to be very high, and brown patch exploded over the last week as well. For our Program '11 treatment, we proceeded as planned on May 23 with an application of 26GT (4 fl oz) + Fore (6 oz). We also made the scheduled application of Terrazole (4 oz, watered-in) to clean up any Pythium root rot activity that may have been triggered by recent wet weather.

The changes that we made to Program '11 have done a good job of getting the dollar spot under control. In fact, Program '11 is the only treatment that is clean of dollar spot this week. All of the other programs contain noticeable amounts of the disease.

All of the programs are providing excellent brown patch control.

Turf quality is still mostly being impacted by dollar spot. Only Program '11 and the Bayer Program are providing acceptable (>5) turf quality, with Program '11 providing significantly greater quality than all other treatments.

  1. I didn't like Call Graph as it crashes sometimes at calls and records not all calls. I moved to Riviera for Skype. Enjoy: Skype Call Recorder
