Over the past couple of weeks, a number of phone calls have been received asking if Section 18 (emergency exemption) fungicides can be sprayed in Iowa. The answer is "yes," Section 18 fungicides may be used in Iowa; however, the Section 18 label clearly states that the products only are approved for the management of Asian soybean rust (ASR). That is, they are not approved for control of other foliar diseases if rust is not present or conditions do not favor ASR development.
