Soybean rust once again did not make it to Iowa in 2009, but it wasn’t from a lack of trying. Rust was found early in Louisiana and eventually was found at high levels throughout the Southeast. These – overwintering finds and high levels of inoculum in the South – are two prerequisites for rust getting to Iowa.
