The Wheat Septoria module allows you to monitor and anticipate the risk of septoria infection (Zymoseptoria tritici) on your soft wheat fields. It combines weather data measured by your Sencrop station (temperature, rainfall, wind) with epidemiological models to estimate disease pressure throughout the season
➡️ The module is accessible to all users with a Sencrop station equipped with a rainfall sensor, a temperature sensor, and an anemometer (wind sensor). Organization owners can configure and share model parameters with collaborator members of their network.
Understanding Septoria Risk
What is wheat septoria and why is it important?
Septoria is the main foliar disease of wheat in Western Europe. It can cause significant yield losses (up to 30–40% in severe cases). It develops in mild, humid conditions: primary contaminations occur from autumn/winter, and spring epidemics are promoted by rain that disperses spores from leaf to leaf.
How is the septoria risk calculated?
The calculation is based on weather data measured by your Sencrop station, combining:
Temperatures (min, max, daily average)
Rainfall (quantity and frequency of rain events)
Crop growth stage (BBCH) of the field
These parameters feed an epidemiological model that estimates successively the probability of sporulation, spore dispersal, and leaf infection. The overall risk displayed results from the combination of these three components. Sencrop weather forecasts allow anticipating risk over a 7-day horizon.
What are the conditions favorable to an infection?
An infection event is considered at risk when the following conditions are met:
Temperatures between 8°C and 25°C (optimum around 15–20°C)
Significant rainfall enabling spore dispersal
Extended leaf wetness duration (generally > 20–24h)
Outside these ranges, the risk is greatly reduced.
Using the Module
How do I access the Wheat Septoria module?
From the Sencrop app:
Go to the Agronomy tab
Select the Cereals module
Add your wheat fields to the module by selecting them and filling in the required information
How do I configure the model for my field?
Once your field is added to the Cereals module, the most important thing is to enter the current crop growth stage and keep it up to date throughout the season: this parameter determines the quality of the model results.
The weather station associated with the field and the sowing date can be modified directly from the field list in the Agronomy tab if needed.
How do I interpret the displayed risk levels?
The module displays an overall risk index on a visual scale with four levels:
🟢 No risk — Few or no active spores, or conditions unfavorable to infection. No action required.
🟡 Low risk — Spores present but conditions only partially favorable. Monitor closely, especially over several consecutive days.
🟠 Moderate risk — Spores present and conditions favorable to infection. Evaluate based on crop growth stage and existing fungicide coverage.
🔴 High risk — High spore pressure and very favorable conditions — infection likely. Consult your agronomist to determine if intervention is necessary.
These levels are indicative and must be cross-referenced with your field observations and the recommendations of your agricultural advisor.
Can I view the history of infection events over the season?
Yes. The module displays, as a chart and table, a chronological timeline of infection events detected since sowing, allowing you to visualize the intensity and frequency of at-risk periods throughout the season.
Do the model results replace the advice of my agronomist?
No. The module is a decision support tool: it provides you with precise weather information and an objective risk signal, but does not replace the agronomic expertise of your advisor. The final interpretation (triggering a treatment, choosing the active ingredient...) must always incorporate your field observations and local recommendations.
💡I am a B2B partner, how can I use the Septoria module with my farmers?
As a network administrator, you can:
Add wheat fields for your farmers, provided they have the module
View on the map the various at-risk fields of your network at a glance
Consult the risk summary for all your monitored farmers, as well as the associated charts and tables
