I have several customers that installed Tifgrand Bermuda over the last year. One of the lawns started to thin and deteriorate rather quickly. No lesions on the blades. No sign of insects. The soil is moist. We tried a fungicide and that did not stop the problem. A week later we went to a different fungicide at the high rate. That stopped it and now the lawn is recovering. I have talked to a couple different companies with the same problem. No one has been able to identify the disease. I was just wondering if anyone else has seen an issue.
