The Ascospore calculation is based on the average temperature during an extended leaf wetness
event. The model utilizies the

required at various temperatures. In general, at least 12-15 hours of continuous leaf wetness are
required when average temperatures are between 10-15 deg C.

Configuring the Powdery Mildew (Ascospore) Calculation
Configuration parameters except for the leaf threshold are similar to previous calculations. The
leaf wetness sensor (Decagon) output binary data, there are no engineering units associated with
the sensor (such as deg C). The graph below shows a typical output. Threshold values around
450 are typical.
