Soybean Rust Update: September 26, 2014

— Written By Carol Hicks

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 Tift County, Georgia, Calhoun County, Alabama, and Acadia and Tangipahoa counties, Louisiana. That puts rust a little closer to Murphy, but not much closer to Charlotte or the rest of the state. To date, the closest rust to Murphy is approximately 130 miles (Calhoun County, Alabama), and the closest to Charlotte is approximately 295 miles (Calhoun  County, Alabama). 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.
