Pros and cons of the regression model, Bayesian network model, and mechanistic model. DFA: discriminant function analysis.
Regression Model | Bayesian Network Model | Mechanistic Model | |
---|---|---|---|
Prediction accuracy low DON | 93.8% | 90.2% | 84.1% |
Prediction accuracy medium DON | 0% | 0% | 0% |
Prediction accuracy high DON | 0% | 0% | 50% |
Possibility to apply in other conditions (e.g., countries)? | High data dependency. Only in those countries/regions with similar agricultural and weather conditions. Validation needed before its use in new agricultural contexts | High data dependency. Only in those countries/regions with very similar agricultural and weather conditions. Validation needed before its use in new agricultural contexts | Low data dependency. The model can be implemented in other countries/regions given that the fungal species are similar. The combination of model output with influencing agronomic practices in a new country/region needs calibration through a specific DFA. |
Prediction time | One week before flowering, using 10 days’ weather forecast data | From beginning of the growing season | From heading date |
Capability to predict unknown situations | No | No | Yes |
Requirement for specific data | Low | Low. Possible to combine expert knowledge with statistical relationships. | High, e.g., heading date, and leaf wetness duration. |
