If you have the feeling that the recommended date for the next spraying after a recent registered spraying in the field register does not adapt, check the following points:
Do you have areas that have not been sprayed (e.g. Piwis/young plants)?
If this is the case, first check which vineyards you include in the recommendation. VineForecast does not yet have its own Forecast models for Piwis, which means that the function does not yet return the appropriate values. Therefore, check the selection of the dropdown at the top right to remove this area from the calculation. In the following selection All vineyards included in the comparison:
However, we can also select the Work area which then creates the recommended action for the vineyards in this work area only. In the following example, the work area Without Piwis selected. The date is now 31 July instead of 19 June:
Have you stored a plant protection product against the relevant fungal disease?
Check again in your documentation in the field index whether you have really stored a product against Downy or Powdery Mildew. Our database has stored the effectiveness against the corresponding diseases. Occasionally it happens that you accidentally select the wrong product from the list or have made a mistake in the selection.
