r/Turfmanagement

​Hi everyone, I've noticed a recent issue on the turf that I need help diagnosing.

​Individual grass blades are turning dark purple and then black. It's not a general chemical burn.

​Here are the details:

​Symptoms: Dark purple/lilac areas that become black on the blades. Also, in some areas, it forms patches that look like it lacks watering/irrigation.

​Turf type: Football pitch (low-cut turf).

​My suspicion: I suspect some type of fungal disease, possibly Helminthosporium (Leaf Spot), but I want to confirm.

​Request:

​Can you help me identify this based on the photos? What type of fungus do you think it is?

​Any recommendations for management or effective treatment?

​I'm attaching macro photos taken today. Thanks in advance for the help!

Hey all, I took over at a course over the winter with 2 greens that have sodded in 007 bentgrass. They’ve had cores pulled on them once only, and we’re starting to see the roots not push. I’m worried the previous super wasn’t aggressive enough with aeration to get rid of the sod layer. We pulled cores in April, I double needle tined this past week and I might again pull cores after Memorial Day weather depending. Thoughts on ninja tines to help get rid of the sod layer as well?

I’m wondering also if it’s normal grass but just has some dirt if deficiency. I did find gravel under parts near the concrete for instance.

Put some zoxy pg and watered it heavy the last week thinking maybe lds and/or disease but seems to be getting worse. Maybe bugs? Thought I’d ask the pros…

I am giving my go at a DIY golf green.
This is upstate New York zone 5b and v8 creeping bent grass out of Oregon “outsidepride”

Getting cut at .315 to limit disease pressure and tolerance to massive amounts of rain but need something for weeds that’s safe on bent and any time to encourage bent grass to spread I do plan to overseed but with an overseed and all the tips I receive here I want to have a decent stand to putt on this fall

Thanks in advance for any advice!!

Some background I’m a 9 handicap right now dads building a pond and getting back into the game so I bought a used pgm22 Honda reel mower and it’s been our father son hobby trying to get this looking good to practice short game putting stuff like that.

Howdy y’all. I just recently acquired a Ryan Greensaire II. I think it’s early-mid 80s with a Kohler Magnum 8. Runs like a champ - I am very excited to get it going on my pitch & putt.

When purchasing the machine, it came with the optional windrower attachment, but no windrower blade.

Do any of you have this piece of kit? I’d love some measurements to start with so I can fabricate my own.

Thanks.

Since everyone enjoyed my crispy dig, wanted to share a crispy cup.

Determined to put my camera roll to good use and establish myself as a father figure in this subreddit.

I bought a house one year ago in Belgium.
This is the yard Right now, full of weeds and clovers…

I have a baby on the way and want a soft lawn for it to crawl without stinging weeds.

Is this still savable or should i just lay new grass mats?

Sprayed with glysophate to kill Lesser Celadine which invaded the grass for the third year the first year I spot sprayed, but obviously did not get all of it came back with a vengeance this year. Lesser Celadine starts growing in early March and it is difficult to spray have to have temperatures close to 60°. It is very invasive. It started in the woods and I tried to spray along my fence line have gotten different opinions. Should we till or use aeration and reseed or just wait until next year and see if it pops up again, obviously we will have to spray again because different weeds will come up this summer. The yard is compacted not sure if it’s ever been aerated. Not sure if.Tilling will spread the tubers if not completely dead. If we do use grass seed, which is the best it probably only gets about four hours of sun many large trees. Three dogs one likes to play ball for a half hour at a time. Will fence off the part that is reseeded if we do that

I see your crispy cup and raise you a nearly invisible plug.

Hi everyone, looking for advice on these symptoms:

Symptoms: Shredded/white tips and necrotic lesions on the leaf blades (see photos).

Environment: Pyrenees (high altitude), heavy morning dew.

Mower: Dennis reel mower.

Is this just dull blades (mechanical stress) or an early fungus like Dollar Spot? Should I apply fungicide or just sharpen and add some nitrogen?

Thanks!
