What are the prospects for a Soybean Rust invasion in summer 2006? Researchers who addressed the National Soybean Rust Symposium last November reviewed last year's efforts to monitor for the fungal disease and made their best forecasts for the coming growing season. You can find the proceedings at here on the web. Of special interest; the presentations in "Session Three: Looking Towards 2006."
Extension Responds - Soybean Rust
Soybean Rust, a potentially devastating fungal disease, was found in Louisiana in November 2004. This was the first report of the disease in the continental U.S. The disease is spread by the wind. Given the right weather conditions next spring or summer, it could blow up to Wisconsin from Louisiana in only a few days. That means Wisconsin growers will need to be prepared for this possibility during the 2006 growing season.
Most recent update: April 2006
As of July 26, Wisconsin still appears free of Soybean Rust. UW-Extension staff continue to monitor.
