Light at the end of the tunnel (e.g., It's August)

It's been a busy week for golf course superintendents in the region as diseases are in high gear and the heat and temperature stress are causing many golf course putting greens to decline. We are hearing a lot of reports of yellowing and discoloration to bentgrass putting greens, possible nematode issues, and the typical diseases that we would expect to see at this time of the year.

Rain storms that swept through much of the mid-Atlantic provided some much needed relief from the drought we were in, but in many cases the rain fell too fast and basically moved via the surface. The good news from that was that many of you who had ponds that were getting low got a "refill". The bad news is that this did little for replenishing the soil and also washed out a few hundred bunkers. There were even reports in parts of southeast PA of flooding due to the massive storm that came through last week. On the other hand, there were also courses that DID manage to get the slow and steady rain that helped to wet the soil. Following these rains, dollar spot became VERY active and anyone not covered with fungicides saw cotton candy fairways on Tuesday.

Heat stress continues to be the biggest issue throughout much of the region and I can't stress enough that just because the turf is declining doesn't mean that it is pathogen related. In many cases, the soil temps are just too high and/or the growing environments too poor. As we hit the home stretch of summer, it is important to continue to be diligent on your water management. Yes, I know that it is not practical for many of you to get out there and hand-water everything as the courses with a $2,000,000 budget do, but the bottom line is that if you are using your overhead irrigation to "syringe" then you are probably over watering (this was from a USGA agronomist who I believe it going to write an article about it for an upcoming issue of the USGA Record).

Active right now: dollar spot, brown patch, Pythium blight, anthracnose, fairy ring, summer patch, others?

Website update: We are in the process of finalizing the details/construction of the new website for Turf Diseases. Some planned features include:
  • More authors for more updates
  • Restructuring of regional updates in line with USGA Regions
  • New "Research" section for the latest research updates from the scientists
  • New "Tech" section (you'll have to wait for the launch to find out more)
  • Disease profiles and Image galleries
  • Disease updates from superintendents
