National Soybean Rust Commentary (updated: 02/16/07)
Soybean rust was found in volunteer soybeans and in soybeans left behind after harvest in Hidalgo County, Texas. This is the first report of soybean rust on soybean in the United States in 2007, and the first report of the disease in Texas this year. Texas also was the first to report rust on soybeans in 2006. All other reports of the disease have been on kudzu this year. Soybean rust has now been detected in eight counties in Florida and five counties in Georgia and Alabama, along with this new report from Texas. The pathogen continues to overwinter on kudzu in parts of Florida, and in a few, small kudzu patches in urban areas in Georgia and Alabama along the border with Florida. Rust has also been detected in the Mobile area of Alabama as well in the city of Montgomery (the furthest north the disease has successfully overwintered). In some cases these overwintering sites have been destroyed mechanically or have gone dormant due to recent cold temperatures. There have been no reports of soybean rust surviving the winter in South Carolina, Mississippi or Louisiana. Scouting efforts are continuing in many southern states for both soybean rust overwintering sites and signs that kudzu is breaking dormancy in these Gulf Coast States.
