Weather and Disease Modeling Resources

UW Extension AgWeather – This site provides easy access to several different types of weather data from our database. Data coverage extends across the upper Midwest. You can also subscribe to daily email notifications for any covered location that include weather, solar insolation, potential evapotranspiration, degree day models, and some pest risk models.

Wisconsin Vegetable Disease and Insect Forecasting Network (VDIFN) – This site uses gridded NOAA weather data and a variety of plant disease and insect development models to predict disease and insect pest pressure in Wisconsin with a friendly, map-based interface.

Wisconsin Irrigation Scheduling Program (WISP) – A complete irrigation scheduling program for your farm, it uses a few simple initial and periodically updated conditions (soil moisture, crop, canopy cover) as well as weather and potential evapotranspiration values (automatically imported but can be manually adjusted).

Network for Environmental and Weather Applications (NEWA) – Run by Cornell, this site uses a network of on-the-ground weather stations and disease and insect models to provide a variety of forecasting and decision-support tools. Weather stations in the NEWA network stretch from the Northeast to Minnesota. This link is to the new interface currently under development. The old site is still available here.

Potato Soil Health Project: The Potato Soil Health Project was established to identify reliable indicators of soil health and effective methods for increasing soil health in potato cropping systems, to learn what determines whether growers adopt good soil health management practices, and, ultimately, to improve soil health in potato cropping systems across the United States.

Wisconsin Clean Hops Program: The Wisconsin Clean Hops Program at the University of Wisconsin-Madison maintains a collection of pathogen-free hop varieties as a resource for hop growers and gardeners. Stock plants are maintained in greenhouse facilities on the UW-Madison campus, and are tested for pathogens on an annual basis.
