Animal and Plant Health Inspection Service
Washington, D.C. (December 1, 2004) - Researchers at the National Plant Germplasm and Biotechnology Laboratory in Beltsville, MD, said today that one of two soybean leaf samples collected near Memphis, Tenn., has tested positive for Phakopsora pachyrhizi, or soybean rust.
Soybean rust, a disease spread primarily by wind-borne spores, has been confirmed in nine states since it was first discovered in the United States on Nov. 10 in Louisiana. Other states include Alabama, Arkansas, Florida, Georgia, Mississippi, Missouri and South Carolina.
USDA encourages growers to contact USDA's Extension Service, their State Department of Agriculture, and their crop consultants to obtain information on what fungicides are registered for use in their states, as well as when these fungicides should be used.
