The instructions below explain how to use the WeatherLink Software’s degree-
day reporting feature to track the development of crops and/or pests. For infor-
mation on degree-days, see “Degree-Days” on page 97. In order to use degree-
days, you must determine the developmental threshold(s) for the desired crop or
pest. The base developmental threshold is the temperature at and below which
development stops. Above the base threshold, development increases until the
temperature reaches the upper threshold, over which development rate remains
constant. Information on degree-day thresholds is available from your county
agricultural agent or university agricultural extension service.
