Since 2005, numerous foliar fungicides were labeled for use in soybean, primarily as a result of the introduction of Asian soybean rust into the U.S. While many of these products have since been approved for a Section 3 label, indicating that EPA has approved their use throughout the U.S., others have not, and their Section 18 labels have expired as of November 10, 2007. The expiration date was after the publication of Pest Management in Wisconsin Field Crops-2008 (A3646), available through UW-Extension, and we felt that it was important to provide a summary update regarding these changes. Currently, if you have any unopened canisters of material for products under the Section 18 label, they should be returned to the distributor and not used on soybean. The return requirement is only if the application of the fungicide was for soybean, as these fungicides may be used on other approved crops.
