Experts at Iowa State University have pointed to three factors that need to happen for soybean rust to get to Iowa: overwinter, movement of rust spores, and favorable environmental conditions. For 2006, environmental conditions in Iowa were not favorable for disease development throughout most of June and July but improved with the frequent rains late in the summer. However, because the pathogen never made it to Iowa, these environmental conditions were of no consequence.
