7. EXTENSION OUTPUTS

7.5. PROGRAMS ORGANIZED BY THE IOWA STATE UNIVERSITY EXTENSION AND OUTREACH (ISUEO) CROPS TEAM

The ISUEO Crops Team organizes several programs throughout the year to educate stakeholders on sustainable and profitable farm production. The programs target agribusiness professionals, independent crop consultants, farmers, and crop scouts. I regularly speak at many of these programs (Table 1). The programs may be held in the field or indoors. Table 1. Summary of crop disease presentations that I prepared and have given at various ISU Extension and Outreach programs.
