Cougar Blight
Cougar blight risk index is calculated using a number of factors. Please look at the chart below to verify which row you are in for this growing season. Compare the index value in the graph to this chart to see your risk.

Cherry Powdery Mildew
The cherry powdery mildew model runs through three stages. First, growing degree days are calculated from bud break.
If the second stage does not occur before a key degree day threshold is reached, the model shuts down for the year.
Secondly, a specific amount of rainfall is needed during a period of 50F or above to trigger the third stage.
If the rainfall event does occur, the third stage begins. At this point we use the Gubler-Thomas Powdery mildew model
that is described in the table below for powdery mildew. To keep things simple, the Gubler-Thomas model is what is
displayed once the specific rainfall event has occurred.
