Turf diseases the past month

Took a couple of shots after the snow has cleared off the golf course here in the suburbs of philly about a couple of weeks ago. We never got around to spraying our tees and greens do to all the renovations going on at the course. Hope you enjoy.

Hmm interesting, and that's on a golf course? That Fusarium Patch (snow mould) might of been caused by to much nitrogen in the fall. Curious to see some after pics lol

We never spray our fairways for snow molds, just the tees and greens (except this year). The gray snow mold damage is already dwindling as the poa is popping through the matted turf. The pink snow mold is always present, as it doesn't need snow cover to form like grey snow mold. Last year and this year were the first two years in a decade or so with grey snow mold here.

I think the to much fertilization thing is a pretty open ended statement you see out there these days. Obviously if you fertilize to much you will get any disease. With snow mold and any other diseases, if you have the pathogen and the right host, all you need is the perfect environment and it will show no matter if you fertilize heavy pr not. Plus on the golf course our fairways, greens, and tees are fertilized by fertigation system not granular applications, so we are controlling how much nitrogen is being put out.

We get the pink mold every year, it is only on the high N lawns. I typically run the blower over the lawns as soon as the snow goes, to clean up leaves that are now glued to the grasses and suffocating them, and this also eliminates the snow mold and there is no visible damage...
Never had the grey mold however...

Thanks, Tombo, great photographs.
Snow is melting fast here--but even when it does, I doubt that I can match those photos.
