Soybean Rust Update: Rust Found in New Hanover County

Soybean rust was detected on soybean in the sentinel plots located in New Hanover County, at the experiment station near Castle Hayne. The sample was submitted this week by station personnel and first identified by Abigail Capps of the Plant Pathology Department. There were only two leaves out of 50 with a few pustules on each leaf. This is the first find of Phakopsora pachrhizi, Asiatic soybean rust, in North Carolina in 2007.

This puts rust about 160 miles from Elizabeth City, 80 miles from Fayetteville, 105 miles from Raleigh, 95 miles from Washington (North Carolina), and 5 miles from Wilmington. Previous finds were closer to Charlotte (120 miles), Murphy (165 miles) and Winston-Salem (180 miles).

In many instances it is too late to apply fungicides to soybean. Some late planted late maturing soybean may still be at risk, but the chances of measurable yield loss from soybean rust are still considered minimal because of the low humidity.
