ALERT: First-ever rust found in N. Carolina -- five counties positive
|
10/28/2005 1:30 p.m. CDT -- For the first time ever, North Carolina officials have found Asian soybean rust in the state. Five counties were confirmed to have soybean rust based on samples collected Tuesday and Wednesday this week.
According to the map and the Chronology of Positive Detections on www.sbrusa.net, the counties are Brunswick, Columbus and Robeson in extreme southwest North Carolina, and Beaufort and Craven counties in the east-central part of the state. Beaufort County, NC, is now the new northeastern-most positive county in the country.
In the NC state commentary, Steve Koenning with the Department of Plant Pathology at North Carolina State University posted the following:
"As a result of monitoring activities conducted by North Carolina State University, a rust pathogen was identified on soybean leaf samples collected from Brunswick, Columbus and Robeson counties, NC, on 10/25/2005.
"Additional survey samples detected rust on soybean in Beaufort and Craven Counties on 10/26/2005. Steve Koenning of the Plant Pathology Department at North Carolina State University made a tentative diagnosis of Asiatic soybean rust.
"Subsequently, the USDA Animal and Plant Health Inspection Service (APHIS) confirmed the presence of Asiatic soybean rust (Phakospora pachyrizi) on these samples.
"This fungal disease was found in Mississippi, Florida, Alabama, Arkansas, Missouri, Tennessee and South Carolina in 2004. This is the first report of this disease in North Carolina, although it has been found in Alabama, Florida, Georgia, Mississippi, and South Carolina in 2005.
"Soybean rust will not impact North Carolina soybean production in the 2005 growing season, because over 80 percent of the crop is mature. The impact on the remaining soybeans will be minimal because of the late entry of this pathogen into the state. Soybean rust does not infect seed and will not contribute to seed rots."
With this report, plus nine counties in South Carolina and three in Alabama announced today, the 2005 U.S. total for rust-infected counties has passed the 100 mark to 104.
