Looked at a couple of lawns today-
Excerpts from a email to one of the homeowners-
Did not see any evidence of insects-damage is not typical of insects like chinch bugs or white grubs. No insects were found.
The main problem you have is what we call necrotic ring spot or NRS
A fungus disease attacking the roots- because of the recent dry weather it is manifesting itself all over the city
No easy cure
See our website library for things that can be some to alleviate the symptoms
Roots are not functioning at 100%
During cool moist weather the symptoms are not visible.
Recommend seeding with a mix containing perennial rye grass -30%- a less susceptible species. Fungus will go away in two to five seasons .
To remove by digging you have to remove 6-8" minimum
Here is the other lawn- visited this front lawn earlier today- homeowner said he had similar symptoms two yrs ago- resodded whole lawn- now it is back- a costly fix that did not work.
Seeding - much less expensive
