IPM and Weather Data Long history of successful IPM programs which base IPM decisions on weather data, models and field observations –Insect phenology and movement –Disease development and spread –Weed phenology –Cultural practices Planting harvesting Irrigation others

IPM is Local IPM practitioners need a high level of precision at the local level Economy of scale leads management of infrastructure towards state or regional level Pests and Pathogens know no borders

IPPC’s Web-based System Multi-state, Multi-scale Serve local, state and national needs for IPM and biosecurity for weather-based risk Open and Collaborative Approach The system is a fully integrated pest management setting for monitoring, diagnosis, decision support, outreach

Online IPM weather, Degree-Day and Disease Models from OSU/IPPC Len Coop, Assistant Professor (Senior Research) Integrated Plant Protection Center, Botany & Plant Pathology Dept. Oregon State University

Weather and Degree-day Concepts 1)Degree-day models: accumulate a daily "heat unit index" (DD total) until some event is expected (e. g. egg hatch) daily: cumulative: Eggs hatch: 152 cumulative DDs Eggs start developing: 0 DDs 70 o(avg) - 50 o(threshold) =20 DD

Disease risk models: Pear scab (Venturia pirina)

NPDN / IPM Partnership to meet overlapping needs IPM needs decision support system for daily decisions on pest management at the local scale. NPDN needs to know what is normal, what is not, at a national down to a local scale. NPDN has highly sensitive and confidential data. Industry has proprietary information. All groups need information on what to expect during an epidemic.

NPDN / IPM Partnership to meet overlapping needs

IPPC / NPDN Web based delivery tools integrate open information (distributed by IPPC) with secured information (housed at CERIS) Maps and reports display pest/ disease incidence and estimate or predict crop risk. Economy of Scale for Infrastructure optomized NPDN and IPM resources. These decision support tools can be interfaced with other systems to create a distributed set of databases for decision support Novel technologies for example PRISM interpolation.

PRISM Parameter-elevation Regressions on Independent Slopes Model Christopher Daly, Ph.D., Director, Spatial Climate Analysis Service, Oregon State University Developed by Christopher Daly, Ph.D., Director, Spatial Climate Analysis Service, Oregon State University a local, moving-window, regression function between a climate variable and elevation that interacts with an encoded knowledge base and inference enginea local, moving-window, regression function between a climate variable and elevation that interacts with an encoded knowledge base and inference engine engine is a series of rules, decisions and calculations that set weights for the station data points entering the regression function. Rules account for the elevational influence on climate, terrain-induced climate transitions (e.g., rain shadows), coastal effects, atmospheric layers, inversions, and the orographic effectiveness of terrainRules account for the elevational influence on climate, terrain-induced climate transitions (e.g., rain shadows), coastal effects, atmospheric layers, inversions, and the orographic effectiveness of terrain
