How and why a single leaf infected with Asian soybean rust was found in Iowa in March are questions that continue to be addressed by federal investigators. Officials with the Iowa Department of Agriculture and Land Stewardship (IDALS) and Iowa State University (ISU) have found no further evidence of Asian soybean rust in the field where the leaf was reported to have come or in neighboring fields.
