Northwest Degree Day Information
In presenting this information, we wish to stress that errors can occur. Use the information with caution. Predictive models do not replace the need for monitoring in the field. If you observe conditions that differ substantially from model predictions, please contact Dr. Coop to determine if the model inputs were incorrect, if the model functioning or weather data are in error, or if the model is inappropriate for your conditions. Dr. Coop's project was funded in part by grants from the NPDN, National Plant Diagnostics Network, the NRI Plant Biosecurity Program, and from prior grants from the USDA-Western Regional IPM program and from Oregon Statewide IPM funds.
