Very impressive symptoms on our site😂. I didn’t have any exposure to mini ring in real life prior to this year. Being honest, I am shocked.
What do all of these white boxes with ultradwarf bermudagrass samples have in common besides the box itself? They all were diagnosed with mini ring this week. We are diagnosing a LOT of UDB with that disease right now. Heads up!

I am curious what answers we would get if showing this to students in turf management or turf disease 101. 😂😂😂

Drone photo time-lapse of what PRR can do to bentgrass in the south. Reach out if you’d like more info. We’ve developed programs that incorporate 5 MOAs to combat it.

Between the rain, Dr. Kerns team at NC State were discussing a timely concern. Pythium root rot.
Best long term treatment: 3 way tank-mix of sunlight, air movement, and drainage.
When not available - programs with Fame + Serata rotated with Resilia did pretty dang well.

We know that the N fert decreases dollar spot, but we don't know why. Our most recent paper led by @Suwell86 suggests that N influences the microbiome, specifically increasing oxalic acid-degrading bacteria, which leads to reduced disease. Give it a read!

Dr. Murphy from @RUturfCenter presents the PhD research of @PingyuanZ at #ITRC2025. Using a resistant cultivar in combination with using threshold-based fungicides applications can reduce input by up to 78%

It has been for us in Wisconsin, now it’s working for Kerns and Co down in North Carolina. Stay tuned for more details…
Super cool study we are conducting that was the brain child of @plkoch2 and @kurtaculous. Potassium bicarbonate suppressing dollar spot quite well. Well done gentleman on this work!

Soil temperatures have risen steadily across SC in the past couple of weeks. If you are in an area prone to mini-ring, know that the fungus causing the disease can be active now even if you aren't seeing symptoms. Good time to be on a preventive program.

Recent weather in the Southeast has been quite favorable for Pythium blight on bermudagrass putting greens.
I would like to take this opportunity to sincerely thank Dr. James Murphy, Dr. Bruce Clarke as my advisors; Dr. Stacy Bonos, Dr. Paul Koch, and Dr. Daniel Ward who served my academic committee at RU. At last, I thank Dr. Bruce Branham who opened the door to turf world for me.
