The United States Department of Agriculture
(USDA) recently announced Asian soybean rust has been identified
in Seminole County, Ga., on volunteer soybeans. This is the
first confirmed U.S. case in soybeans for the 2005 season. The
confirmation was made by officials with the
University of Georgia’s Plant
Disease Clinic in Tifton, Ga.
“While rust has now been confirmed in Georgia on volunteer
soybeans, it’s important to remember that it can be managed like
other soybean diseases, as long as we continue to scout and
monitor its spread,” says Greg Anderson,
United Soybean Board
(USB) chairman and farmer from Newman Grove, Neb. “Soybean
farmers can take heart that we are reducing the potential impact
of rust through our own checkoff dollars. The soybean checkoff
is helping keep farmers regularly informed about the status of
rust so we can take appropriate actions to minimize yield loss.”
The checkoff and other industry partners have worked with USDA
to create a Web site to track soybean rust movement at
www.usda.gov/soybeanrust. The site houses three U.S. maps to
provide the latest disease observations, management tips and
scouting recommendations. The maps are updated by individual
state soybean specialists who make their interpretations and
recommendations at the state and local level. The disease
observation map shows the negative and confirmed observations of
rust, the disease management map provides control
recommendations from each state soybean specialist and the
scouting map shows where and when to look for the first
appearance of disease.
“We know now that all commercial soybean varieties are highly
susceptible to soybean rust, and through our checkoff we will
continue to search for resistance to rust,” says Anderson. “In
the meanwhile, the most effective management plan for soybean
rust comes from early diagnosis and treatment. Farmers should
scout frequently for rust, every two to three days, and apply
fungicides as needed.”
Since rust was first identified in Brazil in 2001, the soybean
checkoff has cumulatively invested more than $2.7 million in
rust research, including in excess of $680,000 for research in
2005. Research projects include evaluating U.S. and exotic
soybean germplasm for resistance, disease management strategies,
assessment of rust migration from South to North America using
models that monitor and predict rust migration, and evaluation
of handheld guides for “field-friendly” diagnosis of soybean
rust.
The soybean checkoff also works closely with other
organizations, including Qualified State Soybean Boards (QSSBs),
USDA, the Environmental Protection Agency (EPA) and the American
Soybean Association (ASA) to inform farmers about the fungicide
options available to protect U.S. soybeans from rust.
“While rust may be a challenge for farmers, it is important to
know that there are no known human health concerns associated
with soybean rust disease,” says Anderson.
The checkoff has developed two diagnostic guides that include
information on rust, available through the checkoff-funded
www.stopsoybeanrust.com
Web site.
USB is made up of 64 farmer-directors who oversee the
investments of the soybean checkoff on behalf of all U.S.
soybean farmers. As stipulated in the Soybean Promotion,
Research and Consumer Information Act, USDA’s Agricultural
Marketing Service has oversight responsibilities for USB and the
soybean checkoff. |
