Soybean Rust Update: September 17, 2009

Asiatic soybean rust was confirmed in five more counties in Alabama, including DeKalb and Cherokee counties, which are closer to Murphy, North Carolina, than any previous finds in 2009. The DeKalb County site is about 100 miles from Murphy, 275 miles from Charlotte, and 325 miles from Winston-Salem. It is a little farther from the other 7 cities we’re tracking than the Berkeley County, South Carolina site. The Berkeley County site is approximately 145 miles from Charlotte, 305 miles from Elizabeth City, 145 miles from Fayetteville, 260 miles from Murphy, 195 miles from Raleigh, 240 miles from Washington, 145 miles from Wilmington, and 200 miles from Winston-Salem, North Carolina.

Rust has now been confirmed on soybeans in Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, South Carolina, and Tennessee. The other counties announced in the past week to have rust on soybeans are all farther away from our North Carolina soybeans than the sites mentioned in the first paragraph.

We do not consider this find to pose any imminent threat to our North Carolina soybeans yet. North Carolina farmers should continue to check their soybeans that have not yet gotten full sized beans in the top of the plants, and to continue to monitor reliable reports of where else rust has been found. An up-to-date map of where rust has been found is at http://www.sbrusa.net. The current version of these North Carolina updates should also be available at our Teletip line: 800/662-7301.
