What Are the Most Common Fungal Diseases on Commercial Lawns in Springdale AR?
Fungal diseases on commercial turfgrass are infections caused by microscopic pathogens that weaken turf structure, stunt growth, and produce visible lesions or discoloration when environmental conditions favor spore germination. In Springdale’s warm, moist spring, five diseases dominate: brown patch, dollar spot, large patch, Pythium blight, and rust. Recognizing their unique symptoms and life cycles is the first step toward precise intervention.
These infections disrupt turf uniformity and vigor, so understanding each pathogen’s preferences enables targeted cultural or chemical controls before damage spreads to surrounding landscaping.
What Is Brown Patch and How Does It Affect Commercial Turf?
Brown patch is a turfgrass disease caused by the fungus Rhizoctonia solani that manifests as brown, smoke-ringed circles in warm-season grasses, enabling early detection and localized treatment to restore uniform coverage.
Circular to irregular patches of tan to brown turf up to three feet across
Dark “smoke rings” at patch edges during dew periods
Leaf tissue collapse under humid, warm nighttime conditions
This pathogen thrives when nighttime temperatures stay between 65°F and 85°F and leaf surfaces remain wet for over 14 hours. Preventing dense turf canopies and adjusting irrigation schedules reduces moisture retention and curtails disease progression toward dollar spot hotspots.
How to Identify Dollar Spot on Commercial Lawns in Springdale?
Dollar spot is a superficial fungal infection by Sclerotinia homoeocarpa that produces straw-colored spots resembling silver dollars, offering visual cues for granular or foliar fungicide placement.
Small, circular lesions (½–1½ inches) of bleached turfgrass
Straw-colored grass blades with reddish margins as spots expand
Occurs most often in nitrogen-deficient turf and when leaf wetness exceeds eight hours
Dollar Spot Disease
Dollar spot is a common foliar disease that affects various turfgrasses, particularly those under low nitrogen fertility programs [6, 9, 11, 19, 24]. The disease is most prevalent in late spring and early fall when high humidity and cool nights favor dew formation [9, 19, 24].

This citation supports the article by providing information on the conditions that favor dollar spot disease, which is one of the common diseases affecting commercial lawns in Springdale, AR.
This disease escalates under moderate temperatures (60–85°F) and high humidity, particularly when nitrogen applications are delayed. Correcting nutrient imbalances and improving air circulation between mower passes can halt lesion coalescence into larger damaging areas.
What Are the Signs of Large Patch Disease in Warm-Season Turfgrass?
Large patch is a spring/fall disease of zoysiagrass and Bermudagrass caused by Rhizoctonia solani, producing irregular yellow to brown bands that signal deep-seated infection requiring root-zone attention.
Broad, irregular bands of discolored turf near tree lines or shaded areas
Grass blades remain attached to stolons, hampering mechanical removal
Soil temperatures between 50°F and 65°F promote sclerotia formation
This disease spreads in cool, waterlogged soils. Aerating compacted zones and reducing excessive thatch accumulation disrupts fungal sclerotia and fosters turf recovery before patches invade traffic areas.
Large Patch Disease
Large patch, caused by Rhizoctonia solani, is a significant disease of warm-season turfgrasses, especially in the fall and spring [5, 13, 18, 23]. The disease is more severe in lawns that are over-fertilized, watered too much, or mowed too short [5, 13, 18, 23].pero

How Does Pythium Blight Damage Commercial Lawns Quickly?
Pythium blight is a water mold disease by Pythium spp. that causes rapidly expanding, greasy, water-soaked patches in high-traffic turf, underscoring the need for immediate drainage correction and fungicide application.
Dark, slimy turf areas that turn grayish and collapse under foot traffic
Cottonlike mycelial growth visible in early morning hours
Thrives when temperatures exceed 85°F and leaf wetness persists
This pathogen can devastate large turf areas within 24–48 hours of onset. Improving soil infiltration and removing surface moisture combined with a curative fungicide spray halts further spread.
What Is Rust Disease and How Does It Affect Springdale Commercial Turf?
Rust disease, caused by Puccinia and Uromyces species, produces orange to brown pustules on leaf blades, showcasing active spore production that signals reduced photosynthesis and weakened turf resilience.
Fine, dusty pustules on upper and lower leaf surfaces
Fading green color and thinning canopy as spores deplete chlorophyll
Develops in 55–80°F range with poor air circulation
This disease often follows prolonged shade and dew. Mowing at proper heights—increasing airflow—and applying contact fungicides can limit spore dispersal and maintain turf density for commercial presentation.
Common Turfgrass Diseases
Rust disease is a common fungal disease that affects turfgrasses, with symptoms including yellow flecks on leaf blades that enlarge and release spores [3, 10, 15, 20, 25]. The disease thrives in warm, moist conditions and can be exacerbated by low nitrogen levels and drought stress [3, 10, 20, 25].
