Last week we discussed Section 18 fungicides and their role in managing Asian soybean rust. However, there are some fungicides that have a full label (Section 3) for soybean. These fungicides can be applied to manage other diseases of soybean as well. See the following table for a complete list of fungicides currently labeled or to be labeled for soybeans in Iowa for management of soybean rust in 2006. For more details on fungicide use for management of soybean rust, please visit www.soybeanrust.info.
