Soybean Rust Update: October 15, 2014
From: Jim Dunphy, Extension Crop Science Specialist, and Steve Koenning, Extension Plant Pathologist, North Carolina State University.
Asiatic soybean rust has been confirmed on soybeans in Floyd and Toombs counties in Georgia, and in Jones and Simpson counties in Mississippi. The Floyd County, Georgia site is only approximately 85 miles from Murphy, and approximately 230 miles from Charlotte. The Toombs County site is also approximately 230 miles from Charlotte. Rust has not been confirmed on soybeans within 300 miles of Elizabeth City, Fayetteville, Raleigh, Washington, Wilmington, or Winston-Salem, North Carolina.
We do not consider these finds to pose any imminent threat to North Carolina soybeans, since essentially all our state’s soybeans are mature enough that they will likely mature naturally before rust can develop enough to cause economic damage. This is especially true since the majority of our state’s soybeans are more than 300 miles away from any confirmed finds of rust on soybeans.
