Final Project Results

Based on the previous three years experience, soybean rust's northward spread seems to take distinct routes. In 2007 the rust spread through the Great Plain soybean-growing region up to northern Iowa. Further examination found that this distinction was associated with the wind patterns supported by large-scale circulation. In the 2006 summer, a quasi-stationary cyclonic circulation anomaly was situated in the central-eastern U.S., whereas in 2007, an anticyclonic circulation dominated the central section of the U.S. Thus, whether there is cyclonic or anticyclonic circulation in the central U.S. is the key in determining the route of northward progress of the rust.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
