Necrotic ring spot treatment from Turf Tonic stops the fungus that leaves frog-eye rings of dead turf in Utah lawns — then helps healthy grass fill back in with a plan built for the Wasatch Front conditions.
If you are seeing circular dead patches, especially in Kentucky bluegrass, you are likely dealing with necrotic ring spot. Early treatment limits spread and shortens recovery time across Lehi and Utah County.
What is necrotic ring spot?
Necrotic ring spot is a soil-borne turf disease common in Utah. It weakens crowns and roots, creating rings or patches of straw-colored grass with living turf in the center (“frog-eye”). Heat, drought stress, and compacted soil make outbreaks worse along the Wasatch Front.
Our necrotic ring spot treatment approach
We confirm symptoms on-site, apply a targeted spray program to suppress the pathogen, and give cultural guidance — watering depth, mowing height, and fertility — so recovery is not undone by stress. Stubborn cases often need multiple visits across a season.
