I apologize for this delayed reply to your gardening question and hope it is still helpful to you.
There is not a product that is best of all disease problems. I suggest you contact your County Extension Office to see about bringing in a turf sample for diagnosis. With an accurate diagnosis they can then recommend an appropriate product and/or cultural technique to get the lawn strong and healthy again.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
