During the dry and warm summers of recent years, the fungal disease Phytophthora in potatoes was well controlled. Resulting in fewer outbreaks in the potato fields.

How different the situation is in 2021. In the summer of 2021, the disease spreads quickly. This is due to the fairly wet weather.

Humid weather conditions in combination with a fast-growing crop ensure rapid spread of the fungus throughout the fields. Good timing of the spray application is therefore very important.

The RMA weather stations in combination with the Rhiza Connect app provide insight into the daily risk of disease infection. The control strategy can be adapted to this in order to prevent Phytophthora.
