Support for grower networks by OSU IPPC - Online IPM weather data and pest models Leonard Coop & Paul Jepson Integrated Plant Protection Center Oregon State University
Outline IPPC Talk - Sept 12, 2006 • Title: "Support for grower networks by OSU IPPC Online IPM weather data and pest models" – 1. Brief history/what we are about as a grantfunded entity – 2. Some issues and problems inherent in using weather-driven services – 3. New and future IPPC products including quality assurance procedures, new models, custom degree-day maps, and insect and disease model forecasts

Weather Networks – How representative? • Dec 05 – where to put next PAWS/agweathernet stations – current area represented each station
Weather Networks – How representative? • Dec 05 – where to put next PAWS/agweathernet stations – current area represented each station
Weather Networks – How to share data? • Campbell-based CPCRC 6 station network – already in publicly available Meso. West database
Weather Network Checklist – What to look for: ✔ Weather station hardware – reliability, uptime, product lifetime, etc. - $$ ✔ Dedicated hardware maintenance – response time - $$ ✔ Type of data transfer to collection points: 1 -way or 2 -way; modem, cell phone, radio, satellite, internet, or? ✔ Database issues – how are the data from various stations stored and accessed? Are missing data auto-resynchronized from sensor to user: station<->gateway<>server<->client partially or completely? ✔ Is there some type of local delivery and support software (models? ) – e. g. the owner's PC - $ ✔ Does the network involve standardized internet data collection and delivery or “Public Aggregation” (e. g. Missoula & Utah NWS Mesowest) ✔ Is there “added value” regarding model development and delivery – such as missing data estimation, intelligent spatial interpolation, integrated forecasts, and Extension service/other expert advising including validations?
IPPC: degree-day calculator and models integrated with 6, 300+ weather stations
IPPC daily online degree-day maps: 48 states

OSU IPPC IPM models – features • IPPC - automated PRISM climate map + nearby station based max-min temperature estimation of missing data • IPPC - use numerous weather networks; higher chance of nearby stations to help estimate missing data • Are missing/bad data feeding the models? How will you know? Need to have option to show the data with model outputs • Pest models database – working with researchers, Extension to develop, maintain, and respond to local user needs for all the models • Forecasts: current – PNW weather. com 10 -day, NWS zone 7 -day max-min forecasts full USA • IPPC/Fox weather 2007 – new research project to estimate missing data(hourly temps, RH, precip, wind speed) using Day 0 forecast data • Forecast models: 2007 – 3 to 5 -day site-specific forecasts for all pest models (IPM weather workgroup grant w/Fox weather, other researchers)

Online Weather Data from IPPC - history • 1995 -6 “bootstrap” era – initial products for Oregon converted from Pascal DOS programs into UNIX • 1996 -1999 PNW 3 -state era, some Areawide Codling Moth funding, initial WR IPM funding • 1999 -2004 WR IPM grants, support OR grower networks and disease models, 5 state NW region (2003: 900+ weather stations, 45 pest models) • 2004 -present Focus on plant disease models, expand to national status (2006: 6300+ stations, 49 pest models), NPDN funding • 2006 -2009 Focus on forecasting for disease models, NRI Plant Biosecurity funding

Conclusions • IPM decision making resides with the grower: decision aids need to be resolved to the field/farm scale • Advanced climate analysis is an effective starting point for development of tools and services • Development model in OR, PNW, West, has recruited large numbers of growers, and is evolving • Plant disease models, supported by improved forecasting, are in development; some released • WIPM Center Weather Workgroup is focusing on standards, quality control, and delivery of comprehensive regional and national services • GIS-based tools offer scope for integration of other IPM decision tools relating to diagnostics, IPM options, and spatially resolved risk and risk mitigation factors
