Soybean rust confirmed in the United States

The U.S. Department of Agriculture reported today (Wednesday, Nov. 10) that soybean rust was confirmed on leaf samples in Louisiana. This is the first instance of soybean rust in the United States.

The disease Phakopsora pachyrhizi, commonly known as soybean rust, has decimated fields on the Asian and African continents and in South America. The disease is spread when rust spores become airborne and travel by wind from one soybean field to another. The effect on this year's crop should be minimal, experts say, due to the fact that most soybeans have been harvested. Soybean rust can be managed using fungicides. More information on soybean rust is available.
