IPM Pest and Plant Disease Models and Forecasting

  For Pest Modeling in the US for Agricultural, Pest Management, and Plant Biosecurity Decision Support in the US
This website brings together US weather data and plant pest and disease models to serve many decision support needs in agriculture. Currently this site provides over 110 degree-day and 23 hourly weather-driven models serving many IPM, regulatory, plant biosecurity, biological control, and conservation uses for the full USA, with emphasis on IPM needs for the Western States.

Weather data and forecasts are currently linked to the models for over 29,000 US and nearby weather locations. Forecast sources include NWS Digital forecasts in all states and Fox Weather LLC forecasts in Western states.

Funding has been provided by numerous USDA NIFA grants, USDA PPQ, RMA and ipmPIPE grants, NPDN grants, WR-IPM Center and Oregon Statewide IPM funds, and local and regional commodity grants.
