How risk is calculated
The dashboard calculates a 0-100 weather risk index. It is not a disease diagnosis or a spray recommendation; it is a decision-support signal for scouting and fungicide timing discussions.
Canola sclerotinia
The index weighs canola flowering stage, canopy density, sclerotinia field history, rainfall in the last 7 and 14 days, wet hours in the last 48 hours and 7 days, relative humidity, and average temperature.
Wheat and barley FHB
The index weighs heading/flowering stage, variety susceptibility, previous crop and residue, 7-day rainfall, 7-day wet hours, relative humidity, temperature, and precipitation probability.
Risk bands
Below 45 is low risk, 45-69 means monitor closely, and 70+ indicates high weather pressure. Always confirm crop stage and field conditions before a fungicide decision.
Lines show a 0-100 risk index. Yellow means monitor closely; red means high risk and a fungicide timing check.

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.
