Soybean Rust Update: October 10, 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 Madison County, Florida;, Dooly and Pike counties, Georgia; Avoyelles, Iberville, and Pointe Coupee parishes, Louisiana; and Amite, Lincoln, Pike, Walthall, Covington, Lamar, Bolivar, Stone, Sunflower, Wayne, and Washington counties, Mississippi. The Pike County, Georgia site is a second site that is approximately 130 miles from Murphy (Calhoun County, Georgia was the first). It is also the closest site to Charlotte, at approximately 240 miles. 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. Soybeans with developing seeds in the top of the plants are probably safe from economic damage from rust.
