Brown, mushy roots:
And, sometimes Pythium oospores (stained pink here):
In the diagnostic lab it has kind of been like that movie Groundhog Day, where each day brings a remarkably similar set of turf plugs.
The stress continues. In the Kansas City area it is still hot with rain, in other parts it is hot and dry. A superintendent over in Kansas City told me that he had recorded a 2-in soil temp of 101. Yikes!
Jim had a nice post this week about the different types of Pythium, and there definitely have been some questions around here. So, if you need some further clarification I suggest reading Jim's summary.
Gray leaf spot
Gray leaf spot is the other big nasty disease on people's minds. There have been reports of GLS showing up early in states farther east, so superintendents in this area should definitely be thinking about it, scouting, getting on their spray programs.
Below is an image of GLS damage in 2007 that was sent in by a superintendent (I cropped it some for anonymity). The plants that are green are weeds (not perennial rye). In this case I believe they re-seeded with Kentucky bluegrass to avoid future problems with GLS.
Turf field day:
We had our annual field day yesterday. Thanks to everyone who came, and to the vendors for supporting this event.
The early part of the crowd mills around at registration:
One of the groups looks at a moss study on one of the putting greens:
I've had some turf samples come in packaged in unusual ways. Here is some turf packed in club-house towels:
There were 5 towels! My Christmas shopping is halfway done!
And another came in a box for Jessica Simpson sandals. Very sassy!
My two favorite boxes of all time are 1) a box from a 12-pack of beer and 2) a box that said "Quik Taters" (some kind of frozen potatoes).
