Potato Late Blight Decision Support System (DSS)
i) standard Blitecast readings (severity values);
ii) predicted Blitecast readings based on future weather;
iii) another disease forecast system (Simcast) that includes fungicide weathering and varietal susceptibility in determining the need for fungicide; and
iv) opportunity to experiment (virtually) with different fungicide strategies before actually making an application.
The DSS allows you to set up individual fields or farm locations that you would expect to have different climate conditions because of elevation or exposure. It saves the information for each field or farm for the season, allowing you to record fungicide applications and track fungicide weathering along with the disease severity.
