| Leaf with soybean rust |
Part of EPA's mission to protect human health and the environment includes strategically planning for the possibility that an invasive species could threaten the food supply in the United States.
Since November 10, 2004, the U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service has confirmed that soybean rust - an aggressive and harmful plant disease in soybeans - has been discovered in Louisiana, Alabama, Arkansas, Florida, Georgia, Mississippi, Missouri, South Carolina, and Tennessee.
Soybean rust is caused by a fungus that spreads by spores that can be carried by the wind. It is believed that spores were carried to the southeastern United States from South America during the 2004 hurricane season.
The soybean plants in Louisiana and the eight other states listed above were infected with the Asian species of the fungus, which is the most destructive variant. Yield losses of up to 80 percent have been reported in soybean-growing areas of South America and Africa as a result of untreated infection by the fungus. The arrival of soybean rust to the continental United States had been predicted by experts for some time, since it is found around the globe in soybean-producing countries and is a wind-borne disease.
EPA, along with USDA and state departments of agriculture, has been planning
for just such an event and has approved a number of fungicides for soybean
growers. The following tables indicate pesticides that EPA has approved
for use against soybean rust as of October 19, 2005. Updates will follow
if additional new products clear the regulatory and safety review process.
Growers should be aware that availability of these products in the marketplace
depends on a number of factors beyond EPA's control, including manufacturers'
marketing decisions, availability of supplies, product distribution and
production, state registration of EPA-registered products, and state requests
for emergency exemptions. Please consult with your pesticide suppliers
and local Cooperative
Extension office 
for information on products that are available to you
locally.
