hot, humid = brown patch

Hot, Humid, & Stormy

The main story this week is that temperatures have surged into the 90’s along with high humidity and more rainfall. We’ve had a string of days where merely stepping outside in the morning leads to sweating. This means it is brown patch season, and not surprisingly there is some activity out there. Earlier this week there was a particularly dewy morning, and I found some mycelium crawling around in the perennial ryegrass at our research facility. Examination in the microscope confirmed that it was brown patch. I’ve seen a few brown patch lesions in tall fescue, too.

Dollar spot continues to be active in many areas. Our research site, Kansas State’s Rocky Ford Turfgrass Research Facility, is wide-open with lots of exposure to Kansas winds. There have been a few dollar spot infection centers, but this week it has really picked up so we can start to gather some data in our trials.

On the ornamental/landscape side of things, a lot of trees in northeast Kansas got totally hammered in heavy winds during a severe thunderstorm on Monday night. There's a lot of tree carnage. So, as if there were not enough to do to manage the turf, now there’s a lot of tree clean-up work to deal with. Proper pruning after storm damage is critical for recovery and the long-term health of trees. Got storm damage at your course? Not sure what to do? The Arbor Day Foundation has some great resources about storm damage in trees on their website:

THANK YOU to everyone who participated in the Heart of America Golf Course Superintendents Association (HAGCSA) Scholarship and Research Tournament on Monday. We at K-State appreciate all the support over the years.

The tournament was held at Oakwood Country Club in Kansas City, MO, with Jeff Elmer as Superintendent.
