Good information here!
Tall fescue lawns are weeping under this lovely hot/wet summer we are experiencing here in North Carolina. While disease pressure is present in some locations, some of the damage we have observed is also weather-related. More below: turfpathology.ces.ncsu.edu/2025/07/gray-l…
Pythium root rot developing nicely at the farm. Second photo shows programs for bentgrass from 2023, 2013, and 2003. New program is rocking!


Field Day Registration is Open!
Registration is now open for our annual turfgrass field day, scheduled to take place in Raleigh, NC, at the Lake Wheeler Turfgrass Field Lab on August 13, 2025. turffiles.ncsu.edu/2025/07/2025-t…
Good advice here!
Putting greens struggling despite your heroic fungicide efforts? Might wanna train your setup folks how to detect black layer. Unless they are nose blind to rotten eggs, they’ll figure it out real quick. Sniff them cup cuts! 🤢
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!

Great trip to speak in Australia. 🇦🇺 Thank you for an incredible trip!




I have two graduate research assistantships opening in the Turfgrass and Forage Weed Science Lab at North Carolina State University. If the outlined projects in description interest you to pursue an MS or PhD degree in Weed Science, consider applying.

Congratulations! Thank you for including me on this manuscript!
So excited to share that my first paper as a lead author has been published! A huge thank you to the REAL experts (and co-authors) on large patch @HutchensWendell, @ArkansasTurf, @purdueturfpath, @KernsJim, @SpurlockLab. Check it out here: dx.doi.org/10.1002/csc2.7… #largepatch
Guess what disease of ultradwarf bermudagrass in Raleigh? Instead of guessing why not send a sample? And here is the appropriate way to collect a sample.

Does pH affect take-all root rot severity? YES. All the plots exhibiting TARR symptoms have a pH of 7.3 to 7.43. All other plots the pH is below 6. Not sure of the exact reason for this, so more to come!

The difference between a fungicide program developed in 2003 on the left and a program developed in 2023. The programs were for bentgrass and these were applied to bermudagrass and bentgrass. Yes modern fungicides have improved!

Sage advice here!
March Madness isn't just for basketball; it's also prime time for preventive apps for diseases like fairy ring, Pythium root dysfunction, and sting nematodes. It's easier to score layups now to get ahead than waiting for the Hail Mary threes in a curative comeback scenario!
