DEVELOPMENT AND VALIDATION OF FHB AND DON PREDICTIVE MODELS FOR BARLEY
Project Number: 0500-00053-002-95
Start Date: May 03, 2009
End Date: May 02, 2013
Development of a web-based risk advisory system that utilizes weather in the forecasting of FHB disease severity and DON accumulation for barley. Specific project objectives are to continue: 1) contributing to the development of an experimental database containing information on cultural practices, weather, and resulting field disease and mycotoxin levels for barley; and 2) model development and validation for FHB and DON accumulation in barley.
Objective 1 will be addressed by establishing multiple (12+) spring barley sites throughout ND, SD, and MN. These will be monitored for disease development, plant growth stage, toxin accumulation, and environmental parameters. These locations will contribute to a growing database of information necessary for model development. For objective 2, data from these, and locations from previous years, will be analyzed and screened by scientists at SDSU for strong relationships between environmental variables and final disease and DON levels. Preliminary predictive models will be developed based on these variables and validated during the 2009-growing season.
