Fungal Control with Fertility

F-15 has been formulated to address fungal root and leaf threats, including brown patch, zoysia (large) patch, mildew, leaf rust, common root rot, and others.

This innovative product utilizes the disease suppression of chloride while providing the benefits of slow release nitrogen.  Chloride research has concluded that it plays an important role in suppression of fungal leaf and root diseases.  Nitrogen and carbon provide the plant nutrition and energy to facilitate recovery from and resist fungal effects.

“We began using F-15 as a preventative in 2021. Since then, our fungus related service calls have been down consistently over 50%. And that includes 2023, a particularly difficult year for brown patch.” – Denise Wartan, CEO Trad’s Pest Control

Used as a preventative, F-15 has been shown to produce up to 50% reduction in fungus growth, reducing service calls and use of chemical fungicides.

F-15 can be used to treat active fungus growth.

“I have used F-15 to recover fungus damaged lawns that homeowners thought were beyond repair. And I have used it religiously as a preventative for four years with outstanding results.” – George Kuska, Owner Kuska’s Lawn Care

The photo of this fungus damage was  taken in August 2021 and immediately treated with F-15.	After three weeks the damage was almost completely gone.  Note the improvement in color typically seen after applying F-15.
This St. Augustine turf was installed new in November 2020. Fungus had nearly destroyed it, and the homeowner considered replacing it. On January 6, 2021 F-15 was applied.	The fungus was stopped immediately.  In spite of a colder than normal winter, the turf had recovered almost completely by the time this picture was taken on February 23, 2021.
