3. El Niño-Southern Oscillation (ENSO) Effects on Hessian Fly Infestation in the Southeastern USA Prem Woli, Brenda Ortiz, David Buntin, Kathy Flanders -To examine the effect of ENSO on Hessian Fly Infestation (HFI) in the Southeastern USA. -To explore relationship between HFI and weather and wheat area. -To assess the impact of HFI on wheat yield as influenced by ENSO. Objectives Results The HFI prediction model was based on : - Temperature and Precipitation of Aug-Sep (TAS, PAS) and Oct-Feb (TOF, POF) periods PLUS - Change in wheat area in the preceding year (ΔWA) Hessian Fly Infestation was significantly lower in El Niño than in the other phases of ENSO HFIP Griffin = 0.012ΔWA + 0.045PAS – 0.017POF – 5.574TAS + 3.139TOF + 112.3 HFI and Yield by ENSO and Variety

4. Corn Aflatoxin Contamination Risk Prediction Based On a Drought Index Damianos Damianidis, Brenda V. Ortiz, Gary L. Windham, Prem Woli – To model the probability of aflatoxin contamination using the Agricultural Reference Index for Drought (ARID). – To determine time windows during the growing season when changes in drought conditions will change the risk for aflatoxin. – To determine how aflatoxin risk changes are affected by soil type and corn hybrids Objectives Assessing the risk for aflatoxin contamination pre- planting or in-season could be used to support changes to management practices Methods – Logistic regression was performed to test the relationship between monthly ARID and corn aflatoxin level exceeding 20 ppb Results Aflaroxin risk for two soil types @ 1 wk before silking - The highest risk to have aflatoxin occurs the week before silking. - ARID can be used to predict Aflatoxin risk. -As ARID values increase, aflatoxin risk increases. Risk changes by soil type.

5. Evaluated the performance of SimCLIM for generating climate projections of specific locations. 15 downscaled GCMs were not significantly different. SimCLIM can provide good projections for climate mean but not for variability. Evaluation of SimCLIM Performance in the Southeast Yawen Bao, Gerrit Hoogenboom, George Vellidis Maximum Temperature Box plots of projections based on 15 GCMs and observations
