Methodology

This is an operational weather index, not a diagnosis. For sclerotinia it weighs canola flowering, canopy density, 7-14 day rainfall, high-humidity hours, and temperature. For Fusarium head blight it weighs crop stage, variety susceptibility, previous crop, rainfall, relative humidity, and temperature before and during flowering.

Weather source: Open-Meteo. Agronomic thresholds are based on public guidance from the Canola Council of Canada, NDSU/USWBSI, and university extension materials. For a production decision tool, calibrate the coefficients against local field history, varieties, fungicide records, and scouting observations.
