Grass Disease

Hello all,

I laid rolawn turf a couple of months back.

All went well, looked nice and green, but over the last 4 weeks, it started to form small brown circles, and now they are getting bigger and they are all over the lawn.

I think its either Leaf Blight or foliar fungus.

Is there a way to be exactly sure, OR, a chemical/fungicide to kill both?

Many Thanks.

I hope I'm wrong but it sounds like Fairy Rings. It is a fungus but it lives in the soil so the only way to eradicate it is to completely remove all your topsoil and get some new stuff in.

how about a photo?

Sounds like it could be red thread. There's been quite a lot of it about so far this year. Can you see a reddish colour in any of the patches? If so cut, wait 3-4 days and apply a high nitrogen granular feed, water it in well then cut about 7-10 days after application. Cut at least once a week after that, twice if possible. If you can, raise your mower height a notch and the lawn will be back to normal in no time.

If it isn't red thread post a pic.
