Evaluation of Organic Soybean Rust Treatmentsfor Organic Production

Authors: , ,


Asian soybean rust (ASR), which arrived in the U.S. in 2004, has the potential to be the single most important impediment to economical organic soybean production in the U.S., with the potential economic impact of ASR in organic systems ranging from $30 to $120 million in soybean yield loss. The fungus(Phakopsora pachyrhizi)survives year-round in warm areas, such as the southern United States. During a growing season, the pathogen is disseminated by northward seasonal wind.
