Crop Disease Risk Monitoring

Know when disease pressure is building

Siora Disease Risk Alerts turns crop-specific weather conditions into a daily seven-day forecast, a within-field risk map, and an email when pressure crosses your threshold.

Within-field risk layer

Early warning

Move from reactive treatment to informed timing

Disease Risk Alerts monitors the conditions that create infection opportunity, helping you decide when to scout, when to prepare, and when pressure is low enough to wait.

See pressure before symptoms

Follow the next seven days of weather-driven infection risk for the diseases relevant to your crop.

Know where to look

Open a within-field risk layer to focus scouting on zones where conditions are most favourable.

Act at your threshold

Set a threshold per disease and receive an email when forecast risk crosses it.

Crop coverage

Check what Siora monitors for your crop

Choose a crop to see the diseases or pests currently covered. Every listed risk is monitored automatically when that crop is selected in Siora.

  • Septoria tritici blotch
  • Fusarium head blight

What drives the forecast

Analysis built around each crop and disease

Siora combines observed and forecast weather with the crop's seasonal stage. Satellite vegetation and moisture signals, together with terrain, show how risk may vary inside the field.

The analysis accounts for the factors relevant to each disease, including temperature, humidity, rainfall, leaf wetness, accumulated warmth, canopy conditions, and hail exposure.

Recent conditions

Observed rainfall, temperature, humidity, and relevant weather history.

Seven-day forecast

Projected conditions from today through the next six days.

Crop timing

Planting date or crop-specific seasonal calendars align risk with growth stage.

Field variability

Satellite imagery and terrain downscale risk into a spatial field layer.

Workflow

From monitored field to early warning

Once enabled, the service runs daily without requiring another order for every forecast.

1

Monitor the field

Disease Risk Alerts is added to a field with active Siora Vegetation Monitoring.

2

Set crop context

Choose the crop and, where relevant, add the planting date for better seasonal timing.

3

Analyse risk daily

Crop-specific analysis combines recent weather, forecast weather, growth stage, satellite data, and terrain.

4

Review and respond

Follow the timeline, inspect the map, and receive email alerts when your thresholds are crossed.

From signal to action

Act earlier and with better timing

A high score shows when conditions strongly favour infection or pest development. That gives your team time to focus scouting, coordinate protection plans, and respond before pressure builds further.

  • Prioritize scouting before a forecast high-pressure period.
  • Time preventative action around the crop and disease risk window.
  • Avoid unnecessary treatment when forecast pressure remains low.
  • Use the map to focus attention on wetter, denser, or slower-drying zones.

Scientific foundation

Established science, applied to each field

Siora builds its crop-specific analysis on widely used disease-forecasting and pest-timing methods. It then combines those methods with field weather, crop timing, satellite signals, and terrain to produce a forecast that updates every day.

Questions

Disease Risk Alerts FAQ

What does a high risk score tell me?

A high score shows that recent or forecast conditions strongly favour infection or pest development. It gives you a clear window for focused scouting, protection planning, and timely action.

How far ahead does the forecast look?

The dashboard shows a seven-day forecast for every supported disease associated with the field's crop.

Can I choose which diseases are monitored?

Siora automatically includes the full supported disease set for the selected crop. You can configure the email threshold and switch notifications on or off separately for each disease.

Why does it require Vegetation Monitoring?

Vegetation Monitoring supplies the current satellite-based crop and moisture context used to create the within-field risk layer, alongside weather and terrain data.

How often will I receive email alerts?

An email is sent when risk newly crosses your threshold. Siora does not repeat the same alert every day while the same disease remains above that threshold.

Add early warning to your field

Monitor crop development and disease pressure together

Start with Vegetation Monitoring, then add crop-specific Disease Risk Alerts to the field you want to protect.
