USDA Confirms Final Louisiana Soybean Rust Sample; Suspected Florida Sample Also Tests Positive

Washington, D.C. (November 17, 2004) - The fourth Louisiana soybean leaf sample, and a suspicious soybean leaf sample that Florida researchers turned in to USDA's National Plant Germplasm and Biotechnology Laboratory in Beltsville, Md., earlier this week have both tested positive for Phakopsora pachyrhizi, or soybean rust, today.

The number of confirmed soybean rust cases in the southeast United States now stands at seven. All four soybean leaf samples taken by the USDA soybean rust detection assessment team in Louisiana have now tested positive for P. pachyrhizi.

On Monday, two Florida Institute of Food and Agricultural Sciences researchers surveyed and collected suspected soybean rust samples from the institute's experimental soybean plots at the Quincy research station after hearing samples taken from Louisiana State University production plots had tested positive for soybean rust. That sample has since tested positive for the fungus.

The Gulf Coast states, to include Alabama, Mississippi, Florida and Georgia, are proactively surveying high-risk areas for signs of the disease. APHIS Plant Protection and Quarantine officials have begun talks with the state departments of agriculture in the region and plan to send soybean rust experts to Alabama, Mississippi and Georgia to assist in assessment efforts.
