SOYBEAN RUST CONFIRMED IN SEVEN NEW COUNTIES
Soybean rust was detected in seven new counties in Alabama this week. On Aug. 22, the disease was detected in a soybean sentinel plot at the Prattville Experiment Field in Autauga County in central-Alabama. On Aug. 23, rust was detected in a kudzu patch in Conecuh County in the town of Castleberry in south-central Alabama. On Aug. 24, rust was found in soybean sentinel plots in New Brockton in Coffee County and at the Wiregrass Regional Research and Extension Center in Headland in Henry County.
The disease was also detected in commercial soybean fields in Dale (Midland City), Houston (Dothan) and Pike (Brundidge) counties, as well as in a kudzu patch in Pike County.
Soybean rust has now been confirmed in 12 Alabama counties as the seven new counties join Baldwin, Escambia, Lee, Elmore and Talladega counties as positive rust locations. In all, rust has been detected in nine commercial soybean fields, eight soybean sentinel plots and four kudzu patches in the State.
There are not a lot of soybeans acres in SE Alabama, and even less between SE Alabama and the east central sentinel plots that were reported positive a couple weeks ago.
However, there are acres and acres of kudzu in between, and officials suspect kudzu is the bridge between the two regions.
Severity appeared to be relatively low, and sporulation is nowhere near what officials say they have seen on soybeans.
"But it's incredible the amount of kudzu that is out there when I consider how much kudzu I see growing along the roadways and what must be growing in places I can't see back from the highway," said Dr. Edward Sikora, a professor and Extension Plant Pathologist with the Department of Entomology and Plant Pathology of Auburn University.
The USDA Soybean Rust Website at www.usda.gov/soybeanrust displays a national map of all counties that soybean rust has been found in for 2005 as well as all scouted regions of the U.S., and a national commentary provided by soybean rust experts with the USDA.
The site also contains images of rust that may be helpful to producers scouting for the disease.
There are links to the Alabama soybean rust web page and the Mid-South Soybean Rust web page www.soyrust.org which provides some good information on fungicides and control.
A hot-line for producers, especially those without computer access, has been established to help inform producers about the spread of the disease. The number is 1-800-774-2847 (BUGS).
