Crop circles or Parasites
For some inexplicable reason I am developing large circles of dead grass on the lawn. The first one I noticed was last year and I thought it might be the way I was mowing. They are circular some 20-25 feet in diameter and perfectly circular. I have had two this year. One circling a tree.
Does the crane flys worms make this circular pattern?
Do I call in the UFO hunters and set up a lemonaid stand on the lawn and charge for over night camping?

There is a fungal disease that attacks turf and kills the grass in circular areas. I can't remember offhand what the name of the fungus is, but I've seen it before. It's weird, the circles are PERFECT - but I've never seen them larger than maybe 3 feet in diameter.

I remember the invasion of the hairy cinch bug (love the name). They wrecked havoc with lawns down south awhile back and killed patches but I don't recall whether it was circular patches. Insecticide worked but apparently a bunch of lawn could be killed before you recognized something was wrong.
My folks had something like that at one place when I was a kid. Green circular bands that expanded and lawn in the centre died. Fungicides didn't do much, but something I'll call a hose aerator worked reasonable well. It was a maybe 8" tube on a handle that you poked into the ground and it injected water below the surface. I don't remember much about it but using the thing was one of my chores.

It's Cinch bugs for sure, get that lawn treated or you won't have one left in SHORT order.
Call any proffesional turf care (spraying) company, they will send someone out to examine the situation and recommend a course of action, if you're still not sure call a second company for a second opinion.
Then FOLLOW THE ADVISE they give you.
Tom is right, industry estimates say that approx. 25% of untreated lawns were lost to Cinch bugs in the last few years in southern Ontario.
Best of luck.

I think the fungal disease I was referring to was called fairy ring. Who names these things anyway?

Fairy ring is what I was thinking of as well. Typically mushrooms come up in the outer part of the ring sometimes. The term came from early times when fairies were thought to dance around such rings at night. Now I've got an image of hairy cinch bugs dancing in the dead grass and the grass probably is creeping red fescue. Who names theses things indeed.

These are definately rings. They look like the dog has run around in a circle for few days. I have never seen any fungus come up at the edges and as I have centipee they fill in with risomes quickly after they are finished.
Can you charge tickets for the fairy rings? I guess it requires a different level of nut than the UFO buff.

I have a couple of big dogs, a golden retriever and now a german pointer, but I have never seen them run in cicles nor do they have problems with incontinence. With the heat it is hard to get the retriever run at all. He has determined that air conditioning is fine and has determined to plant himself in the basement.

I think I recall when the cinch bug problem first cropped up of hearing that the bugs could be found by running some soil through a screen. If that's what it is, you really want to take action quickly.
