Dollar Spot Risk Predictor

Monitor dollar spot disease risk with the Smith-Kerns prediction model. Enter your location for a real-time risk assessment built from local weather — five-day average temperature and relative humidity — so you can time preventive fungicide applications instead of guessing.

How it works

  • Smith-Kerns model — the university-validated logistic model used across the turf industry.
  • Local weather inputs — the tool pulls current conditions for your location automatically.
  • Actionable thresholds — see when risk crosses the 20% spray-decision threshold.
