BBRO - cercospora on sugar beets

BBRO is a British scientific research institute specialising in beet cultivation. The organisation has developed an indicator that helps you to trigger your beet cercospora treatments. It is now available in the Sencrop application!

Crop: Beetroot

Measurements needed: Hygrometry and dry temperature

Availability of models: Plan Plus


Risk of cercospora on sugar beets

Cercospora is a fungal disease that affects the foliage of beet. The disease develops rapidly under favourable conditions with an average temperature of 20°C and 80mm of rainfall during the growing season. Without intervention to stop the infection, the spots multiply until the infected leaves completely dry out. It can lead to losses of up to 30% of root weight and a drop in sugar content of 1 to 2 points.

The indicator provided by BBRO takes into account the humidity as well as the dry temperature, calculated from the ultra-local data of the Sencrop stations. In effect, this tells you the potential for disease infection over a previous 48-hour period. Infection is calculated from the average temperature and the number of hours that the relative humidity is above 87%.

It is then a real early warning to apply the first fungicide to protect your crop and avoid yield loss.


How does the model work in the application?

Sencrop integrates these disease models into its application and allows you to visualise in real time (and up to 4 days) this pressure on your plots. You will find 3 indicators according to the calculated risk:



The expected risk is high It is advisable to start your treatments to protect your crops.



The expected risk is uncertain. Plan a possible treatment to protect your crops, depending on your other indicators.



The expected risk is unlikely You can save inputs for future interventions.
