Justification and Implementation: The pathogen causing Soybean Rust (SBR) was introduced to the United States in 2004. Although the pathogen, Phakopsora pachyrhizi, can only survive the winter in the gulf coast states, it can spread North in the summer, potentially threatening soybean production in New York and the northeast. Predicting risk of SBR occurrence and distribution has been greatly enhanced by the availability of timely monitoring information available through the USDA IPM PIPE effort. Since it's initial detection in the US, SBR has fortunately, not caused economic losses in the northeast. New York participated in the national Soybean Rust surveillance initiative (now called Soybean Rust IPM PIPE) from 2005 – 2009 to detect soybean rust and provide an early warning to farmers in time to apply protective fungicides if warranted. Fortunately, soybean rust has not to date progressed into New York State by the end of a soybean growing season. But it has come close – southwestern Ontario in fall 2007 and southeastern Maryland in fall 2008 (Figure 1). The soybean rust IPM PIPE effort was modified in 2010 to focus on southern states as Tier 1 early detection areas that could also serve to alert more northern states as to potential risk of a SBR epidemic. Fortunately, SBR was not widespread in 2010, remaining largely confined to the gulf coast region of the southern US subsequently posed minimal to no risk for a SBR epidemic for soybeans grown in the northeast (Figure 1).
