Brown/Yellow spots in St Augustine Lawm
Help! We have an otherwise beautiful St. Augustine grass lawn in Wilmingtin, NC.
Had some small patches of this yellow/brown circles this spring. Lawn/garden store advised to spray with antifungal . . . Martin's Honor Huard PPZ (contains propiconazole triazole). Seemed to help, lawn thrive in summer. Fertilized with 16-4-8 twice during summer (most recently August).
Since late September/early October, it has returned with a VENGEANCE and is spreading. I sprayed the antifungal about two weeks ago and again today. Any other thoughts ???
