(posted 2-21-08)

Jim Marois, Professor of Plant Pathology at the University of Florida reported that soybean rust was found on kudzu in Duval County yesterday, 2/20/08. This is a historically positive site, but the first time visited in 2008. He indicated that he would turn the county map red when data are uploaded. The rust was found on leaves that were probably several weeks old and on newer leaves (2 weeks?) indicating that the rust is spreading. Also the uridenia on the newer leaves were very light colored with light colored spores – indicating from our experience to be young infections. Weather forecast for the next few days at the site are expected to reach the highs in the 70s with rain.

Where Did It Come From? Asian soybean rust was first observed in Japan in 1902, and was found throughout most Asian countries and in Australia by 1934. It currently is found in Africa, Asia, Australia and South America. This disease is spread by spores that are carried by the wind. If spores are killed of by the cold winter weather in the United States, it is expected to make its way to the United States from areas south of the US again next year.
