Animated maps showing 2005 vs 2006 vs 2007 vs 2008 spread of soybean rust over the year.

These four animations depict counties with confirmed observations of soybean rust infections in soybean and/or Kudzu for 2005, 2006, 2007, and 2008. The frames were extracted from the 2005 USDA Soybean Rust Information System, 2006, 2007, and 2008 Pest Information Platform for Extension and Education (PIPE) at weekly intervals.
