response: Also with no disrespect I do NOT think we are dealing with fairy rings. I am familiar with the difference.  My husband and I used to be on the HOA Board of Directors and when we were handling this situation we had a solid diagnosis from a certified lawn care specialist but the other board members didn't want to spend the money on the cost to attempt to eradicate the fungus.   They need to understand that this will NOT go away on its own amd it is starting to degrade our property values. These lawns used to be extremely plush and beautiful but they are going south fast due to this fungus.   Thanks again, Patty       Sent from my Verizon, Samsung Galaxy smartphone        -------- Original message -------- From: Ask Extension <<personal data hidden>>  Date: 7/23/24 6:42 PM (GMT-06:00)  To: Patty Allen <<personal data hidden>>  Subject: Re: Necrotic Ring Spot (#0148272)

response: Hi Maureen!   I have lots of information regarding necrotic ring spot.   What I am really looking for is confirmation from a master gardener confirming that this does appear to be necrotic ring spot. I am dealing with a Board of Directors of our HOA that doesn't seem to understand the importance of this fungus and the fact that it does need to be treated.   If you are able to respond to my original request with your opinion (confirming the diagnosis if you agree) I would greatly appreciate it. I know this can be expensive to treat but it needs to be handled correctly but a licensed and certified lawn care specialist, not just "a guy who mows lawns" which is what we are currently dealing with.   Appreciate your professional opinion!

response: Good Evening Patty,  I think you know more about necrotic ring spot fungus than I do. We are Extension Master Gardener volunteers who answer yard and garden questions. I am not a certified lawn care specialist and cannot confirm a diagnosis on your sterile turf grass lawn from a photo.  Here is a link to the U of M Plant Disease Clinic. For a fee, you can send a sample for a diagnosis: https://pdc.umn.edu/ I will provide a link to our Extension Lawn care calendar: https://extension.umn.edu/planting-and-growing-guides/lawn-care-calendar If you choose to spend resources to get the spots to go away on your lawn, I suggest you contact your lawn care specialist again.  We have had inquiries from various HOA members requesting information about pollinator gardens and lawns and alternative grasses to Kentucky bluegrass.  I will include a few links here for you to consider with your HOA: https://extension.umn.edu/lawns-and-landscapes/planting-and-maintaining-fine-fescue-lawn https://extension.umn.edu/lawns-and-landscapes/flowers-pollinators Good Luck!
