Vegetable Disease & Insect Forecasting Network
Visual map-based interface to view disease risk models, insect developmental models, and degree-day accumulation in Wisconsin and surrounding states. This is the newest and most advanced tool we have available.
Degree Day and Disease Severity Maps
View maps of degree day accumulation based on your parameters.
Degree Day Calculator
This calculator allows you to input your location, method of calculation (e.g. average/modified/sine), and the appropriate biofix dates.

Frost Map
The first map shows the median DOY of first frost; for each map location, half the years were earlier than this date, half later. The second and third map show the earliest DOY of frost in the dataset, and the latest, respectively.
