How long does Honor Guard PPZ Fungicide last before re-treating for brown patch in my lawn?

The turf grass is empire zosyia, and we are located just north of Orlando, Fl. As a preventative in advance of brown patch, how often and what months should we be spraying?


Honor Guard PPZ Fungicide should be used every 14-21 days before the disease is present. The mixing ratio is 1-2 fl. oz. per gallon of water. Brown patch will flourish in prolonged hot and humid weather, so you likely will not need to apply before temperatures reach 70 degrees. See our Brown Patch Treatment Guide for more information about treating for this disease.
