Soybeans. rust confirmed in S. Florida sentinel plot

Florida reported a find of Asian soybean rust today on a sentinel plot near West Palm Beach, just north of Miami. Here's an excerpt from the report:

"This plot was identified as being near a source of rust, so its early infection is not surprising. At this time no other sentinel plot in Florida is known to be positive, although several others are near known rust infestations. On June 11-13, Tropical Storm Alberto moved through Florida. Although the western panhandle was not affected, Tallahassee received 4 inches of rain, with more rain and wind toward Jacksonville. The direction of the storm path was towards the northeast, so if any spores were carried from Florida and the southeast they would likely have ended up in the eastern seaboard. With this said, we feel the overall production of rust spores in Florida is still very low due to our previously dry conditions; the spore load would probably be greater with storms later in the season. Following Alberto the soils are saturated and there is considerable fog and dew formation, providing further opportunity for rust to develop. If Alberto does have an impact on soybean rust, we expect it to be observed in the sentinel plots during the next few weeks. The Florida kudzu canopy is fully developed and flowering. All other soybean sentinel plots are still negative and at R1-R3 maturity stages."
