The Iowa Soybean Rust Fast Track System was developed to allow the rapid and accurate diagnosis of samples suspected of being infected with the Asian soybean rust fungus. Early symptoms of various infectious leaf diseases of soybean often appear similar. A positive identification may require incubation of leaf samples in a moist environment and subsequent microscopic examination. Samples submitted to the Iowa State University Plant Disease Clinic through the Fast Track System are given priority status and diagnosed for Asian soybean rust free of charge
