Necrotic ring spot, also known as frog eye because of the unique pattern it creates on your lawn, is a harmful lawn disease that affects the cool-season grasses in Iowa during the fall season. This disease appears as circular rings of dead grass and attacks the roots of your lawn, making it particularly destructive, and if it's on your lawn, you should treat it immediately. However, the symptoms could look similar to drought or other diseases, so you should hire a professional to confirm whether or not it's necrotic ring spot. Once you confirm that you are dealing with this lawn disease, you should sign up for a curative treatment. Professionals will apply an effective fungicide to get rid of the disease and recommend other lawn care treatments to help it recover; fertilization, aeration, and overseeding are great services that will help to replenish your lawn's health.

Necrotic ring spot is a lawn disease that affects cool-season grasses, primarily Kentucky bluegrass. This disease attacks the roots of your grass and will start showing in late summer-early fall, though it could also present itself during the growing season. Also known as frog eye, this lawn disease appears as circular rings of dead grass around a patch of healthy grass; this unique pattern earned itself the name because it resembles a frog's eye.
