Our Minnesota lawn has developed a very severe case of Nacrotic Spot Lawn Disease. We have Kentucky Bluegrass which I understand is most susceptible to this and of which is due to not aerating. We were hoping that somebody out there has gone through this experience and were wondering how they were able to kick it. Help??!!

For clarification purposes, I think she meant to type: “Necrotic”.

I was wondering if these rings are small or large? I have them also, fairly larger rings, the color of the rings are almost hay color and in the middle is alive green grass..they are on the front lawn and the side..can you describe yours?

I ran into multiple case of Necrotic ring in my clients lawns. The best way to control it is to let the soil breath, make sure that the roots are going deep into the soil if not you may have too much water in your lawn. Aeroate your lawn to strengthen the roots. And don’t cut the grass any shorter than 2 inches. In some major cases we had to scalp the lawn, put down a 4 inch base of topsoil and re-seed. Once you have Necrotic ring there is really no way to kill it, say with a herbacide.

necrotic ring spot is a fungus- herbicides won’t have anything to do with it! use a quality professional fungicide- maybe only availabe in your area from a licensed applicator.

The universal solution to all turf fungal diseases is ordinary corn meal applied at a rate of 20 pounds per 1,000 square feet. It takes 3 weeks to work but it works every time. You should be able to find it at a feed store in 50-pound bags for $5. You can apply any time of year, rain or shine.
